Measuring up a roller shutter for a renovation in Saint-Laurent-du-Var: the trade checklist

A badly handled survey on a renovation is never recovered on site. It is paid for in rework, in a unit that cannot be used, and in a phone call to the customer to move the date. You know how to hold a tape measure; that is not the question. The question is the order of operations and the points that decide the outcome. Deductions and tolerances depend on the product chosen: those get confirmed with us, never from memory.

Before the tape comes out, look at what is there

Start by observing.

Identifying the existing installation

A built-in box at the head of the reveal with the curtain behind it, a monobloc unit married to the joinery, an original window-and-shutter block, a shutter added to the outside of a seventies villa: these do not share the same dominant constraint. Open the box if it opens. Look at how the barrel is held, whether someone has been in before you, whether a makeshift screw is jamming an end plate. We regularly receive surveys that are immaculate on paper, taken on a box nobody had opened.

The intended product decides the method

Three families come up in renovation, each imposing its own reading of the opening:

  • The traditional shutter put back inside an existing box. The constraint becomes the internal volume of the box and the room left for the roll.
  • The monobloc, fitted with the joinery. Coherence with the new window and its frame governs the whole survey.
  • The renovation shutter, face-fixed or under the lintel. Here the wall, the plumb and the obstacles outside dictate the measurement.

The choice follows from what is there and from the result expected. Our made-to-size roller shutter ranges cover all three, and a borderline configuration is settled beforehand, on the phone, before any material is cut. What each one means on site is set out in our guide to changing a roller shutter without opening a wall.

What to record, according to the intended fitting

The table below works as an aide-memoire on site. No values appear in it, deliberately: what changes is the priority of the survey, not the millimetres.

Intended fitting Record first The point that decides the job
Traditional, inside an existing box Internal volume of the box, real clearance between end plates, condition and position of the barrel, curtain height The room available for the roll: it governs the choice of slat
Monobloc with new joinery Bare reveal dimensions after removal, wall thickness, any lining or dry lining, planned frame position Coherence between the block and the window ordered alongside it
Face-fixed renovation unit The wall as substrate, plumb of the outer face, projecting obstacles, sill overhang, acceptable depth outside What the fixing substrate is made of, and what projects around the opening
Renovation unit under the lintel Clear height under the lintel, flatness of the lintel, return of the end plates, clearance left for the rails The clear height under the lintel, which is almost always tighter than expected

One opening can belong to two families. That is where a phone call saves a day.

The survey, point by point

Width and height, in several places

An old reveal is rarely square. Masonry that has settled, render made good three times over, a sill deformed by water, jambs that belly out. One measurement taken in the middle describes nothing usable. Take the width at the head, at mid-height and at the bottom; the height on the left, in the centre and on the right. On tall openings, put the tape away and work with a rigid rule: a tape that twists gives you a wrong figure delivered with confidence, which is far worse than an uncertain one. What governs manufacture is the least favourable value, the one that leaves the narrowest passage.

Send us the raw figures.

No averaging, no rounding, no deduction applied at your end. Deduction rules depend on the product and we give them to you; an installer who applies them before ordering creates precisely the problem they think they are avoiding.

“I’ve measured this way for twenty years”

That is the objection we hear most, and it is a fair one: an experienced fitter reads an opening before measuring it. The problem is not the skill, it is the handover. A correct figure inside a fitter’s head is worth nothing on an order form, because they are not the one cutting the profile. We manufacture what is written, not what was meant. So the survey is not an exercise in measuring, it is an exercise in communicating with the workshop.

Plumb, square, and flat end faces

The level goes against the jamb itself, not against a frame that is heading for the skip. Then check for square, and run a straight edge across the reveal faces and the back of the opening to find a lean or a belly in the render.

A known defect can be dealt with. A defect discovered on fitting day has to be endured, because a guide rail will not follow a deformed jamb without putting the curtain under strain.

Room for the rails, and what you are fixing into

A width that looks sufficient on the tape is not necessarily sufficient for the product. The rails take room on each side and reduce the final clearance. Check that the space on each jamb accepts the rail planned, allowing for whatever is staying: retained frame, trim, lining.

Then look at what you will be screwing into. Concrete, stone, hollow brick, shuttering block, timber frame, added insulation: the fixing follows from that, and a doubtful substrate is flagged at the order rather than at the moment the plug spins in the void. On villas in the hills it is not unusual to find a stone jamb on the left and recent dry lining on the right, on the same opening. Write it down. Those are two different fixings, and they are not improvised from a mobile tower. Note the aspect too when the opening faces the water: screws and attachment parts are not chosen the same way on shutters exposed to salt spray.

The sill, the upstand, the obstacles

This is the part most often forgotten.

A projecting sill or an upstand at the bottom changes how the rail terminates and how the curtain seats. Add to that whatever is lying around the opening: window handle, balustrade, downpipe, return wall, surface cable, hinged shutters the customer wants to keep. What is not reported is not anticipated, and gets discovered with a drill in your hand, in front of the customer, on a Friday afternoon. Take thirty seconds to write down everything that projects near the opening, including what strikes you as unimportant.

Roll direction, control side, and where the operation exits

Two lines that stop a production run

State which side the curtain rolls and which side the control is on. Above all, write down the point of view you are speaking from: without it, “on the right” is a coin toss. We would far rather have an order that says “right-hand side seen from inside” than one that says “as usual”.

Where the operation comes out

Strap, winder, cable exit, wired control run: the place where the operation passes through the box or the masonry is machined, and that machining cannot be moved afterwards. Record what exists, then report the real constraints: consumer unit at the other end of the room, dry lining, fitted furniture, return wall. An exit point chosen by default, without looking at the room, is always paid for at connection.

What a motor adds to the survey

The motor is prepared during the survey. Note the side wanted, whether there is a usable supply nearby, and the aspect of the façade if a solar solution is in play. With no supply available, radio control or a solar motor avoids chasing a wall the customer has just had repainted, and our comparison of radio solutions helps settle the choice before ordering.

The manual override

Check it will still be operable once everything is fitted. That access is reserved at manufacture, not at fitting.

Roll space, the constraint discovered too late

Inside an existing box, the question is not whether the shutter fits the width. It is whether the curtain has room to roll. The roll the curtain forms occupies a volume that depends on the height of the shutter and the slat profile chosen. When the box is too tight the roll rubs, the travel stays incomplete, the hatch no longer closes cleanly, and the customer rings you a few weeks after fitting thinking the motor is faulty. The motor has done nothing wrong.

Your survey therefore has to describe the inside of the box: usable volume, position and condition of the barrel, presence of an inspection hatch, any deformation. Those are what steer the choice of slat, not the other way round. On tight configurations, the right profile sometimes saves a box everyone had written off, particularly with the low-bulk solutions in the Vision+ range.

Photograph and annotate

One general view, one of each jamb, one of the sill, one of the box open, plus a dimensioned sketch in your own hand. It takes a few minutes and removes half the questions. When a joiner sends us that set with the order, we confirm or raise the alarm straight away, without four emails.

The survey sheet: what has to be on your order

Information to send Why it cannot be left out
Existing type of fitting and intended product Determines the measuring method and the manufacture
Widths taken in several places The least favourable value governs the product
Heights taken in several places An out-of-square reveal makes a single measurement false
Plumb, square, flatness of the end faces Decides whether the rails will sit properly
Space available for the rails Avoids discovering at fitting that they do not go in
Usable volume of the existing box Steers the slat choice and the roll
Nature of the fixing substrate Determines the fixings and whether it is feasible at all
Projecting sill, upstand, obstacles Changes how the rail ends and how the curtain seats
Roll direction and control side Governs the machining; holds the job up if missing
Where the operation exits Machined in the workshop, not changeable later
Motor, power supply, manual override Determines the motor and the override access
Colour references Avoids a shade mismatch and a wait for confirmation
Annotated photographs of the opening and the box Confirm what the text does not say

Copy that list into your notebook once and you will never read it again. A survey that ticks every line never comes back to us for more information.

The most frequent survey mistakes

Do I measure the opening or the existing shutter?

The opening, and the clearance genuinely available. Never the product in place: the existing curtain is smaller than the opening, and copying it condemns the new shutter. It tells you about the configuration, not about the dimensions.

What do I do when the reveal is out of square?

Record it as it is and report it. Adapted rails, a local repair, a change of fitting type: the solutions exist as long as the defect is known before manufacture.

Can the existing box be kept?

Often yes, if its usable volume allows the curtain to roll fully and the structure is sound. To be plain about it: this is the point on which we most often ask for a photograph before confirming an order.

Why is a height taken from the sill a problem?

Because a projecting sill or an upstand shifts the starting point of the measurement. We see rails ordered short for that reason alone. Always state the level you measured from.

In doubt about a dimension? Call before you order

The rule fits in one sentence: anything that makes you hesitate on an opening is settled before the order, not during the fitting. A three-minute call with two annotated photographs costs less than a curtain remade, and you know that already. The real question is whether you take up the habit on your next job.

Send us your survey and your photographs and we will tell you what is feasible and what needs a decision — start here. On a job at Saint-Laurent-du-Var or higher up the valley, a check on site remains possible; the simplest thing is to say so when you send the survey.

Roller shutters in a Cannes apartment block: getting approval

An owner calls us, the measurements are taken, the colour is chosen. Then comes the question that suspends the whole project: does the syndic know? If you own a flat in a French building, roller shutter approval is settled before the quotation, never after the fitting. Here is what we see come through, what holds a file up, and how to build one that gets voted through the first time.

Your shutter is private, the façade is not

Two logics for the same object

The roller shutter serves your flat and nobody else’s. You operate it, you maintain it, you replace it when it gives up: it belongs to the parties privatives, the private parts of the building, and no one is going to dictate what kind of curtain hangs behind your window. The box, the guide rails and the outer face of the curtain, though, are visible from the street. They belong to the appearance of the building as much as to you. That boundary, and not a question of ownership, is what decides whether your project has to go to the general meeting.

What can be seen is decided by everyone.

We put it that way on the phone because the confusion comes back every month. An owner feels at home, therefore free. They are free as regards the mechanism and how comfortable it is to use. They are not free as regards the colour their neighbour opposite will be looking at.

Read the building’s rules before you fall for a colour

The règlement de copropriété, the deed that sets the rules of the building, is the document nobody digs out of the file, and it settles half the matter. Some say nothing at all about shutters. Others fix the colour of the joinery, the position of the box, sometimes a single model for the whole building, with a descriptive schedule that must not be departed from. In the newer residences in Nice and Cagnes-sur-Mer that schedule almost always exists, and it makes life simpler: the colour is written down in black and white, and the discussion stops before it starts. Take the time to read it before falling in love with anthracite grey.

Where nothing is written down, what exists becomes the reference: the colour already fitted, the box height of the flat below, the profile of the curtains in place. No text, but a custom the meeting will expect you to respect.

How the vote actually works

This is the heart of it, and it comes down to very little.

The syndic prepares, the meeting decides

Any work that changes the external appearance has in principle to be authorised by the general meeting of owners, even when it is carried out on a private part and paid for by one person alone. The syndic — the managing agent — does not authorise anything: they receive the request, check it, and put it on the agenda. The conseil syndical, the owners’ council, gives an opinion. The decision is taken in the meeting and recorded in the minutes.

Agreement given over the phone is worth nothing. Get it in writing.

Which majority applies depends on the nature of the work, and it is for the syndic to say which one when drafting the resolution. That sounds like a formality. It is not: a resolution passed under the wrong majority remains open to challenge, and the owner who fitted their shutters in the meantime is left alone with the risk. We would rather wait for the wording to be checked than take a box down the following year. Ask to see the draft resolution before the notice of meeting goes out, and read it with the same attention you give the quotation: a comma in the wrong place on the colour will follow you for years.

Replacement like for like

Same colour, same type of box, same geometry as seen from the pavement: the façade does not change, so nothing is modified in the sense the building’s rules mean. A great many files stop there, with a letter of information to the syndic and dated photographs. This is also the territory of the lighter interventions, curtain alone or box re-equipped, that we describe in our guide to replacing roller shutters without building work. But “like for like” has to be demonstrated. It cannot simply be asserted.

Which is exactly where a manufacturer nearby changes things.

Fitting a motor and nothing else

Swapping a winder for a motor cannot be seen from below. As long as the curtain, the box and the rails stay where they are, you are in your own home. It becomes a collective matter the moment a cable runs along the façade, a trunking appears under the balcony, or a box gets screwed to the outside wall. A radio motor, and a solar motor even more so, avoids that debate before it begins.

What the syndic needs from your file

A syndic hardly ever refuses on principle. They put things off when they have nothing to show the meeting. When a file reaches us with two photographs taken into the sun and a quotation with no colour reference, we already know it will be adjourned.

  • A dated written request, naming the flat, the floor and the openings concerned.
  • Usable photographs: the whole façade, then each opening square on, box and rails visible, taken with the sun behind you.
  • The RAL colour reference for the box, the rails and the curtain, with the finish stated (satin, textured).
  • The technical description: type of box, material, overall dimensions, projection from the face of the wall.
  • An itemised quotation naming the manufacturer and the fitter.
  • The chosen control method, with the position of the control points.
  • An argument about harmony: how the product matches what is there, or could serve as the reference for the replacements that follow.
  • An undertaking to bear the cost, the upkeep and the reinstatement should the shutter ever be removed.

A file like that defends itself in the meeting. That is all anyone asks of it.

Preparing a resolution that stands a chance

The calendar matters more than the argument

The meeting only deliberates on what is on the agenda. A request that arrives after the notice of meeting has gone out will not be considered, however good it is and however urgent: it waits for the next meeting. Every spring we see the same jam of requests submitted too late, followed by the same shutters fitted without waiting, then the same painful regularisations. Send the file to the syndic well ahead of the meeting season, then ask for written confirmation that the resolution is on the agenda. Without that confirmation you have nothing.

A shutter that has stopped working does not justify going ahead anyway. A like-for-like repair does.

Three cases, three routes

Before advising a client on how to proceed, we place the project in one of the situations below. The sorting is done on a single criterion: what a passer-by will see once the job is finished.

Situation External appearance changed? Goes to the general meeting Documents that decide it
Like-for-like replacement No, if colour, box and profile are carried over In principle no; a written notice to the syndic is advisable Photographs before the work, colour reference, product sheet
Motorising an existing shutter No, unless a cable or box shows on the façade No if everything stays inside, yes if the façade is touched Type of motor, position of the controls
New shutter, different colour, different box, or a projecting box Yes Yes, as a resolution placed on the agenda Complete file, quotation, harmony argument

Answer the objections inside the resolution

The objections never vary: the colour, how far the box sticks out, and the notion that saying yes once opens the door to anything. Deal with them in the text of the resolution rather than out loud in the meeting, where you will have a few minutes and no photographs on the wall. A request that proposes a rule for the whole building goes down better than a request for an exception.

Nobody enjoys voting for an exception.

When the whole building does it at once

A façade that becomes coherent again

In the tightly packed buildings of Le Cannet and Cannes, the façade tells the story of successive replacements: whites that do not answer each other, box heights that change from floor to floor, curtains of different generations that are not ageing at the same rate. On the seafront, salt spray adds its own mark and widens the gap. A decision taken for the whole building brings the façade back into line and sets a reference that later replacements only have to follow.

The syndic gains one point of contact and one job to oversee.

What a building-wide order changes

A single measuring visit, one colour to coat, fitting that moves from floor to floor: the conditions bear no resemblance to those of a one-off order. In the older residences of Nice it is also the moment to deal with the weatherproofing of the rails and to move to motorised operation while the access is already in place.

Have both scenarios priced. The gap makes the argument better than any speech.

Why a workshop nearby makes the file easier

Matching a shade fitted a long time ago, reproducing a slat width that appears in no current catalogue, adapting the height of a box to a lintel that is not straight: these are workshop questions, not online-order questions. We coat to the RAL chart and manufacture to size at La Gaude, which means we can hand an owner a real sample rather than a picture from a brochure. That sample, held against the existing shutter and looked at in the morning and again late in the day, ends more discussions than a whole meeting. You can look at the boxes and curtains we make, and at how the workshop works.

Three traps that end in reinstatement

Fitting before the vote

This is the heaviest risk, and it does not fade with time. The building can require the work to be brought into line, or even the shutter removed and the façade made good at your expense, long after the job. Having paid in full regularises nothing. Having chosen a good product does not either.

We have turned jobs down for this reason.

The “near enough” colour

A white is not a white. Two neighbouring references are perfectly distinguishable on a south-facing wall, and the difference leaps out when one is satin and the other textured, because the light does not catch them the same way. The classic objection, which we hear every week: “it’s the back of the building, nobody sees it”. The neighbour in the block next door sees it very well from his balcony. Have the exact reference written into the resolution that is voted: it protects the building as much as it protects you.

It is the leading cause of disputes after the event.

The box that sticks out

Projection is checked with a line pulled from the face of the wall, not by eye from the balcony. A rail wider than the old one, a different slat pitch, a thicker bottom slat: each of those details counts as a change of appearance, even if the whole thing looks discreet from below. Look too at solid balustrades and fascia bands, which constrain the fitting, and at the rules that apply in conservation areas, which come on top of the building’s own.

The questions that come up in the meeting

Who pays, if the shutter belongs to the owner?

They do, unless a building-wide operation decides otherwise.

What is the risk in going ahead without approval?

Being made to bring the work into line at your own cost, removal in the clearest cases, and a lastingly strained relationship with the owners’ council. The time saved is paid back later.

Can the syndic approve it alone?

No, not once the external appearance changes. They prepare and table it; the meeting authorises.

Is a vote needed to fit a motor?

Not if everything stays inside the box and the room. A radio or solar motor removes the cable on the façade, and with it the debate. Visible trunking, on the other hand, has to be voted.

Build your file before you order

Dig out the building’s rules, photograph the façade and then each opening square on, and note the colour reference of your current shutters. With those in hand a quotation can be written seriously and a resolution can be defended. We prepare the product sheets, coated samples and images the syndic will ask for: start your quotation request and tell us how your building is arranged. Managing agents and fitters are quoted the same way for grouped operations, colour included.

Roller shutters by the sea in Villefranche-sur-Mer: what the salt really attacks

On the coast, a shutter does not age at the same speed as one fitted up at Grasse. A roller shutter by the sea collects a salt deposit that never stops arriving, even when the curtain has not moved for weeks. From the seafront at Cagnes-sur-Mer to the Cap d’Antibes, we see the same faults come back, with the same explanation behind them: the shutter was decent, its fittings were not.

Under the sea wind, a façade never stops working

Sea air is not a breeze, it is an aerosol. The wind tears microscopic droplets off the surface of the water, the water evaporates, and what stays behind is salt crystals settled on everything in front of it: glass, sill, curtain, guide rails, box. Those crystals have an unpleasant property — they pull moisture out of the surrounding air. At night, as humidity rises, they turn back into a liquid, conductive film pressed against the metal. By morning it has all dried. The cycle starts again the following evening, and not one drop of rain is needed. That mechanism, rather than the storms, is what wears out coastal shutters.

When the surface protection has been breached

The curtain itself holds up rather well.

Aluminium does not rust. It does something else: it pits. Small isolated craters eat into the metal wherever the coating has been pierced, scratched or cut through. Seen from the garden the shutter looks perfect. With your nose against the slat you can make out a scattering of dull white spots, sometimes a halo lifting the paint slightly around them.

And it is almost never the curtain that goes first. The trouble declares itself in what surrounds it: brackets, curtain clips, barrel, bearings, locks, screws. No sales leaflet mentions those parts. They are what decides how long the whole thing lasts. One piece of good news in passing: nearly all of them can be changed with the box open, which brings a great many coastal jobs back to a renovation with no building work at all.

Guide rails, seals and brushes

The guide rails gather everything the wind carries. Salt, fine sand, pollen, mineral dust: the mixture packs down into the bottom of the channel and becomes an abrasive paste. The curtain still comes down, but it scrapes, and the movement turns noisy and hesitant at the end of its travel. We regularly take calls about “a tired motor” on seafront flats; the motor is usually in excellent health and the rail is full. The seals and brushes take salt and ultraviolet together: they harden, they let air through, and the salt then reaches the one place it should never get to, inside the box.

The motor strains silently. Nobody hears it wearing out.

Aluminium or PVC against salt: the honest comparison

The question comes up at every appointment along the coast, and it deserves better than a stock answer. This is how we work through it in the workshop, criterion by criterion, before recommending a material.

Criterion Powder-coated aluminium PVC
Sensitivity to salt A metal open to attack as soon as the protection is breached; everything rests on the coating Not a metal, so out of reach of electrochemical corrosion
Behaviour under UV Colour stays stable where the coating has been done properly More prone to chalking and colour shift in strong shades
Wide openings Wider curtains, better behaviour in wind More modest sizes, more distortion in heat
Observed weak point Fittings, drilled holes left unprotected, edges cut on site The metal parts that go with it: barrel, mechanism, screws, fixings
Where it belongs Front-line façades, wide openings, a lasting appearance requirement Ordinary window sizes on sheltered façades

“My neighbour fitted PVC and has never had a problem.” We hear that a lot, and it deserves a straight answer. PVC is indeed untroubled by salt. But a PVC shutter is not a shutter without metal: its barrel, its curtain clips and its fixings all are. If those parts come out of a standard batch, that is where the shutter will fail, and the material of the curtain will make no difference. A well-coated, well-equipped aluminium shutter, on the other hand, goes through the years on a seafront without incident. Our roller shutter ranges exist in both materials, and the decision is made opening by opening.

Material does not rescue a badly equipped shutter.

A coastal shutter is judged first on its coating

A coating is not a colour, it is a treatment. How well it lasts depends on what came before the paint: degreasing, surface preparation, curing. Skip the preparation and you get a beautiful profile on delivery, then a patch of lifting paint a few seasons later. Ask for a reinforced treatment for aggressive environments, and have it written on the quotation.

Drilling a coated profile opens a door

Any machining done after coating creates a bare area. A drilled hole, a re-cut edge, a stroke of the file: that is where corrosion starts on a façade at Golfe-Juan. Restoring the protection after cutting is not a refinement, it is the condition for everything else.

Another site habit that costs dearly later: metal shavings left on the sill or dropped into the bottom of the rail after drilling. They oxidise where they lie and mark both the sill and the profile for good. A vacuum and a damp cloth on fitting day is all it takes to avoid that.

Manufacturing to the exact measurements spares most of that cutting in the first place.

Why we talk about screws at the quotation stage

It is the most neglected item in the trade and probably the most decisive one on the coast. An ordinary screw driven into an aluminium bracket brings two different metals together with a salty electrolyte between them: galvanic corrosion sets up at the interface, the joint works loose, and on the day someone has to intervene the screw head crumbles to dust under the bit. Out comes the extractor, the bracket gets damaged, and a ten-minute job becomes half a day. No customer should be paying for that kind of repair on a shutter that is still young.

The points we check, and that you are entitled to ask about:

  • screws chosen for a marine environment, not whichever ones were left in the bottom of the toolbox;
  • consistency of metals between the screw, the part being fixed and the substrate;
  • curtain clips and attachment parts treated as well, not merely painted;
  • bearing plates and barrel supports protected through the material rather than on the surface;
  • plugs suited to the real substrate, whether concrete, hollow brick or a timber reveal;
  • a box left clean at the end of the job, with no filings or offcuts in it.

This level of detail is written down nowhere. It has to be asked of the manufacturer and checked at fitting. On exposed openings around Cagnes-sur-Mer, it is what separates a shutter you forget about from one you have to go back to too soon.

Three levels of exposure, three ways of looking after them

Not every address in the department gets the same treatment. We think in three families.

Level of exposure What to watch What upkeep involves
Front line facing the sea: the Cagnes-sur-Mer promenade, Saint-Laurent-du-Var, Marina Baie des Anges, the Croisette Permanent salt deposit, wind carrying sand, screws and clips first in line, seals that harden quickly Rinsing with clean water far more often, a visual check of the fixings at every clean, rails kept clear
Second row, a few streets back: Golfe-Juan, Mandelieu, central Menton, behind the Cap d’Antibes A real deposit, softened by the buildings; wide variation depending on whether the façade takes the sea wind Regular rinsing of façades facing the water, rails cleaned, seals watched
Inland but close by: La Gaude, Vence, the heights above Cagnes Occasional salt carried in on windy spells, dust and pollen dominant, sharper temperature swings Ordinary upkeep, plus a rinse after episodes of sea wind and a check of the rails

Rinse rather than scrub

The useful gesture is neither polish nor a miracle product. Salt dissolves in water, so you rinse it off, curtain fully down, paying attention to the face that looks out to sea. For the bottom of the rails we use a cloth wrapped round a flat rule or a soft spatula, which reaches the paste of sand in the base of the channel without scratching anything.

  • Clean water, curtain down, box and rails included.
  • No pressure washer, which drives salt water under the seals and into the box.
  • No solvent and nothing chlorinated: mild soapy water, then a rinse.
  • Never a metal tool in the rail, never an abrasive pad on a slat.
  • With a check of the seals and brushes: suppleness, shrinkage, hardened patches. They are wear parts and they can be replaced.

Which leaves the question of how often.

We refuse to give a calendar, because it would be wrong. A front-line façade facing the sea and taking the wind off the water needs attention that bears no comparison with a flat three streets back sheltered by its neighbours. Two façades of the same building age differently according to which way they look. The reliable guide is not a date, it is the look of the curtain: as soon as a whitish veil starts to show on the slats, or a finger run along the profile comes away chalky, the salt is there.

And motors in a salty environment?

Against everyone’s intuition, fitting a motor protects the shutter. On a motorised unit the tubular motor lives inside the barrel, which sits inside the box: it is one of the best-sheltered parts of the whole assembly. Compare that with a crank handle, whose exit from the box and universal joint stay outside taking the spray all year round.

That argument is rarely heard in a showroom.

Radio control adds a benefit that is quieter still. A wired control point means going through a wall and running a cable; on a coastal façade every hole is a route by which salt-laden damp migrates into the masonry and the box. With a Somfy radio transmitter, io-homecontrol or RTS, or a CAME receiver, that hole disappears. We have covered the differences between the radio technologies and what a Somfy io motor with feedback brings elsewhere; facing the sea, the thing to remember is that one cable less means one hole less.

One last reflex: a stiff shutter should never be forced. Holding the button down on a curtain that is scraping makes the motor work in overload for a problem that water and a cloth would solve.

What coastal owners ask us

Does a roller shutter by the sea cost more?

The extra sits in the surface treatment and the quality of the fittings, not in the principle of the product, and it is worth weighing against the repairs it avoids. What it comes to depends on the façade, which way it faces and how far it is from the water: it goes on a quotation.

Does facing the sea mean aluminium is compulsory?

No. Properly coated aluminium is a very good choice, but PVC keeps its place on ordinary sizes and sheltered façades.

My curtain has little white marks — is it finished?

Rarely. Surface pitting stabilises with consistent rinsing, and a damaged slat or part can be replaced individually on a product made to measure. A survey on site settles whether it is a repair or a replacement.

Can a manual crank be kept on a seafront?

Yes, as long as you accept that the exit from the box and the joint stay exposed, and therefore need watching more closely.

Take stock of your real exposure

Our advice fits in one sentence: decide the level of protection from the façade, never from the catalogue. A due-west opening on the promenade and a courtyard opening in the same building call for neither the same surface treatment, nor the same screws, nor the same upkeep. We manufacture in our workshop at La Gaude, we deliver across the department, and we would rather tell a customer an opening poses no problem than sell them protection they do not need.

Tell us which way your openings face and how far they are from the water, with a photograph of the façade if you can.

Replacing roller shutters in Nice without major building work

A curtain stuck halfway, a snapped strap, a box that no longer opens: the worry is always the same one, and it is not about the shutter. It is about the builders. In most homes on the Riviera you can replace a roller shutter without opening a wall, provided the starting point is the opening you already have and not a page in a catalogue. Here are the three ways it is done, what separates them, and the moment when the angle grinder has to come out after all.

What “without building work” actually covers

No masonry does not mean no intervention

The word works frightens people because of what comes with it: dust, an open wall, a room out of use, paint to redo. What we call a dry renovation is an intervention that touches neither the wall, nor the window reveal, nor the joinery. No lintel cut into, no channel chased for a cable, no rendering to patch, no plasterer to bring back after us. The fitter works on the shutter and its accessories, leaves with the debris in a bucket, and the room is usable that same evening.

It is a stepladder job, not a scaffolding job.

Three families, one deciding factor

Depending on what has actually worn out, the renovation covers the curtain alone, the contents of the existing box, or a complete shutter fixed to the face of the wall or under the lintel. These three families answer to different states of wear, and they mix happily: on one house we often treat two windows with a new curtain and a third with a face-fixed unit because its box is finished. The choice is not made on the headline price. It is made on the condition of the box, judged with the inspection hatch open.

New curtain, re-equipped box, or a face-fixed unit

Changing the curtain only

This is the lightest intervention and often the most rewarding. The box, the barrel and the guide rails stay; the slats go, along with the parts that wear: curtain straps, bottom slat, end stops, automatic locks where they are fitted. We replace every strap, including the ones that look sound, because plastic that has spent years in a box baked by the sun snaps clean off at the next dismantling. The clearest sign of this kind of wear is a curtain that rolls up in a staircase, offset on one side, because the clips have let go along a single row.

A new curtain is made to the measurement of the opening as it is, not to the theoretical size in a catalogue.

A curtain cut short leaves a strip of daylight at the bottom — nobody notices it in a showroom and everybody notices it on the first night, particularly in a child’s bedroom. A curtain cut wide rubs, then scratches, then buckles.

Re-equipping the box in place

Here the built-in or tunnel box stays exactly where it is. What changes is what it contains: barrel, winder or motor, curtain, guide rails. The façade does not move by a millimetre, the opening loses no daylight, and you get new mechanics with a motor if you want one. Two conditions apply: a sound box, and genuine access to the inside of it. The inspection hatch has often been sealed shut by successive coats of paint; we free it along the joint with a blade, and that is usually the moment we find out what state the barrel is in.

A damp or cracked box changes the conversation.

Fitting a renovation shutter, face-fixed or under the lintel

When the original box is beyond use, unreachable, or when the window never had a shutter at all, we fit a complete assembly whose box is part of the product. It is fixed to the outside face of the wall, or under the lintel inside the reveal. No masonry is opened: the box stays visible, and that trade-off is exactly what saves you the building work. What has to be checked is the room available, since a balcony rail or a rainwater downpipe is enough to complicate the fixing.

The three solutions side by side

Solution What the work involves Effect on the façade Effect on daylight When to choose it
Curtain only Curtain and wear parts removed, new curtain made to size None, if the colour is kept None Box, barrel and rails sound; curtain broken or buckled
Re-equipping the existing box Barrel, motor or winder, curtain and rails replaced inside the box in place None, the box stays the original one None Complete old installation, box sound and accessible
Renovation shutter, face-fixed or under lintel Complete assembly fixed to the wall or under the lintel, no masonry opened Box visible outside or in the reveal Slight, depending on position and box size Original box beyond use, unreachable, or no shutter at all

Checking feasibility before you order

This is what we look at before anything goes into production.

  • The state of the box: cracks, damp marks, sagging, enough internal width for a new assembly, a workable inspection hatch.
  • The reveal and the lintel: sound substrate, square corners, a reliable fixing possible.
  • The guide rails: side play, brush seals torn out, corroded channels, true vertical.
  • The real measurements, taken at the top, the middle and the bottom, because old Riviera masonry is almost never regular.
  • The obstacles: balcony rails, window handles, hinged shutters being kept, an existing awning.
  • How much daylight can be given up, room by room.
  • Appearance constraints: the building’s own rules, the coherence of the façade, local planning rules.
  • Exposure: salt spray, wind, full afternoon sun on west-facing walls.

A curtain that rattles in the wind almost always means dead brush seals rather than a shutter at the end of its life. A new curtain is then enough, and the quotation looks nothing like the other one.

This survey is also what allows us to say no. We would rather tell you a light solution will not hold than force a product into an opening that will not take it. A customer remembers a shutter that rubs for a very long time, and a discount on a quotation for about a week.

Adding a motor without breaking into a wall

Radio removes the cable to the switch

What has always stood in the way of motorising an existing shutter is not the motor, it is the cable. Getting a control to a wall switch means a chase, a conduit, a patch, then a band of paint that never quite matches. A radio motor solves half of that: the control point becomes wireless and goes where you want it, on the wall by the door or in a handset that follows you round the house. Somfy RTS, io-homecontrol, CAME radio — the logic differs from one to the next, and we set out those differences in our comparison of radio motors for roller shutters.

A solar motor goes further than that.

Solar removes the cable altogether

A small panel charges a battery housed with the motor, the commands arrive by radio, and there is nothing left to run: no supply to create, no conduit, no rendering to make good. The whole fitting stays dry. This is what we recommend for an isolated window, an outbuilding with no power, or a flat where drilling the façade would need a vote at the owners’ meeting. The panel simply needs a decent exposure, which takes a few minutes to check on site. On a north wall closed in by the building next door we would rather stay with a mains motor and say so plainly. Our article on choosing a Somfy io motor covers what a connected motor changes day to day.

Think about the day it fails, too: a solar motor has a manual override, and that override has to stay reachable without a ladder.

When a light renovation is no longer enough

Some situations fall outside all of this, and saying so early saves everyone’s time. A cracked box that puts the lintel in question needs structural repair, not a cover-up. A window due for replacement calls for a built-in shutter fitted with the new joinery, which is the best moment to deal with both at once — that is joinery work, and we supply the shutter rather than fit the window. An enlarged opening is a building job. And wanting a box completely hidden where no box has ever existed is paid for in building work: that is an aesthetic choice, made with open eyes, not a technical constraint. Our range of roller shutters covers all three families, from the tunnel box to the aluminium or PVC renovation unit.

The millimetre decides the result

A successful renovation cannot be seen. It can be heard even less: no vibration when the mistral gets up, no rubbing, no stray daylight under the curtain. Improvised fixes on site — stacked packers, added angle trim, oversized seals — start to show after a few seasons. Making each unit to size in our workshop at La Gaude, for jobs that run from the hills behind Grasse down to the seafront, lets the product go into the opening as it actually is, including when it leans.

What we get asked most

Can a roller shutter be replaced without building work in a flat?

Yes, in most cases, by changing the curtain or re-equipping the box. If the outside appearance changes, the owners’ meeting still has to approve it, even though not a single brick has moved.

Will I lose daylight?

Only with a shutter fitted under the lintel, and only slightly if the box is sized to what is actually needed.

How long does the work take?

It depends on the number of openings and the solution chosen: a curtain is quick, a complete box takes longer. The survey is what allows a reliable duration to be given before the order, and we hold to it.

Can a shutter be motorised without an electrician?

With a solar motor, no new power supply is needed.

Have the feasibility checked before you buy

Open the box, or have it opened, before you order anything at all. Everything else follows from what is found in there. Tell us about your openings and we will say which solution applies and which one we are ruling out — ask us for an estimate and describe the configuration you have. We manufacture and supply; private customers are put in touch with an approved installer near them, and the joiners and blind specialists who work with us order made to size direct.

Roller, motorised and solar insect screens: the complete guide

Roller, motorised and solar insect screens: the complete guide

An insect screen is a simple product that is easy to get wrong. Almost every complaint we hear traces back to the same mistake: the wrong type for the opening. Get that decision right and the screen becomes invisible; get it wrong and you fight it every day of the summer.

Start from the opening, not the catalogue

The rule is close to arithmetic. Taller than wide, the mesh should travel vertically. Wider than tall, it should travel sideways. That single comparison eliminates most of the wrong answers.

  • Standard windows — a roller screen. The mesh winds into a slim cassette at the head and drops in front of the opening.
  • French doors and sliding bays — a side-sliding screen. The mesh crosses horizontally, so you are not winding two metres of mesh every time you step onto the terrace.
  • Large spans and exposed terraces — a motorised screen, driven like a roller shutter.

What makes a roller screen last

Three components decide it, and none of them is the mesh.

The internal mechanism: the springs should be heavy-duty, silent, and the return speed adjustable with the screen already fitted — because a screen that snaps back is a screen that will be torn within two seasons.

The seals: one or two PVC seals at the roller close the gap above the mesh. Without them, flying and crawling insects simply come in over the top, which is the most common reason a screen “does not work”.

The side channels: telescopic and adjustable, to take up any out-of-plumb in the opening, with brushes closing the sides.

Motorised and solar: when they earn their place

Past a certain area a screen becomes uncomfortable to operate by hand, and the mesh copes badly with wind. A motorised screen solves both. The ZIP versions weld a bead along each edge of the mesh and run it inside a closed channel, so the mesh cannot pull out and stays taut instead of billowing — which is what allows the very large spans, and what makes screens viable on the open sides of a pergola.

Solar versions exist where bringing power to the opening would mean opening a wall. The same caveat applies as for shutters: the panel needs real exposure to work properly.

The mesh is a real choice, not a detail

  • Standard grey — general purpose, and the most discreet from outside.
  • High transparency — a finer thread and more open weave, for when the view is the reason you bought the house.
  • High contrast — easier to see through against strong backlight.
  • Fine weave — for the smallest insects.
  • Anti-pollen — filters a large part of airborne pollen, for hay fever sufferers.

Made to measure, and why it matters here

Riviera openings are rarely square, particularly in older buildings. A screen built to the measurement taken at the opening seals at the perimeter; one bought to a nominal size leaves the gaps that let insects in. Everything we make is built to the measured dimension in our workshop at La Gaude.

Why choose a Somfy io motor for your roller shutter

Why choose a Somfy io motor for your roller shutter

Motorising a roller shutter is rarely a question about the motor. It is a question about the cable, the wall and what you want the shutter to be able to tell you. The Somfy io range answers all three, and it is the range we fit most often — but not in every case, and it is worth knowing why.

Two-way radio, which is the real difference

io-homecontrol is a radio protocol shared by several manufacturers working in home automation. Its defining property is feedback: the shutter does not only receive orders, it answers. It can report its exact position, the temperature at its control point, and the battery charge if it is solar-powered.

In practice that changes what the installation can do. A one-way system sends an order and hopes. A two-way system knows whether the shutter actually moved — which is what makes reliable scheduling, grouping and remote checking possible.

868 MHz rather than 433

io motors work at 868.95 MHz. That band is far less crowded than the 433 MHz used by many cheaper systems, so it is less exposed to interference from other devices. On top of that, the protocol sends several command pulses per button press, so a single missed pulse does not mean a shutter that ignores you.

Fitting without opening the walls

The obstacle to motorising an existing shutter has never been the motor — it is running a supply to a wall switch. That means cutting a channel, sleeving it, filling it and repainting a strip that never quite matches.

A radio motor removes half the problem: the control point becomes wireless and can go where it suits you. A solar io motor removes the cable entirely — a small panel feeds a battery housed with the motor, and orders arrive by radio. That is the option we suggest for an isolated opening, an outbuilding with no supply, or a flat where drilling the façade would need a vote at the owners’ meeting.

Solar has one real limit and we would rather state it: the panel needs decent exposure. On a north elevation closed in by a neighbouring building, we will steer you back to a mains-fed motor.

The protections that pay for themselves

More than half of all call-outs on roller shutters are caused by something left underneath the curtain, and very often the curtain is what gets replaced.

  • Obstacle detection stops the motor before the hardware breaks.
  • Frost protection puts the motor into a safe mode rather than forcing a frozen curtain.
  • Reinforced braking stops the motor being back-driven by someone lifting the curtain from outside. With anti-lift locks, that is a genuine additional barrier.

A step towards home automation, if you want it

Because io is shared across brands, an io shutter is not a dead end. It can later join a Somfy TaHoma box alongside gates, lighting and heating, and be grouped or scheduled. If you never want that, io still works perfectly well as a plain handset-operated shutter — you simply will not use the feedback.

When we suggest something else

If you want a straightforward radio link, no feedback and a lower price, Somfy RTS or a CAME radio motor does the job. The comparison of the four families is set out in our radio motor comparison.

Radio motors for roller shutters compared: RS 100, Oximo, Altus and CAME

Radio motors for roller shutters compared: RS 100, Oximo, Altus and CAME

Four radio motor families cover almost every roller shutter we build. They are not interchangeable, and the choice is decided by the weight of the curtain first, then by the protocol you want to live with. Here is what actually separates them, from the manufacturer that fits them.

Torque before anything else

Torque, in newton metres, is what lifts the curtain. Get it wrong and no feature list will save the installation.

  • RS 100 — 6, 10 and 20 Nm. Small to medium windows.
  • Oximo — 30, 40 and 50 Nm. Larger openings and heavier aluminium curtains.
  • Altus — the RTS workhorse across a similar range.
  • CAME — an alternative radio family we also fit.

io-homecontrol: the protocol that answers back

io-homecontrol is a radio protocol shared by several manufacturers committed to home automation. Its defining feature is feedback: the shutter can report its exact position, the temperature at its control point, or the battery charge if it is solar. Communication is two-way — the handset sends the order, the shutter replies.

io runs at 868.95 MHz. That band is far less crowded than 433 MHz, so it is less exposed to radio interference, and the protocol sends several command pulses per button press to make sure the motor receives the order.

The protections that save the curtain

More than half of all call-outs on roller shutters are caused by something left underneath the curtain. Very often that ends in a replaced curtain.

  • Obstacle detection. io motors detect the obstruction and stop before the hardware breaks.
  • Frost protection. If the curtain is frozen, or the motor is dangerously outside its operating temperature range, it goes into a protective mode rather than forcing.
  • Anti-intrusion braking. Reinforced brakes stop the motor being back-driven by lifting the curtain. Combined with anti-lift locks, that is a real additional barrier.

Noise: where the RS 100 stands apart

The RS 100 is quiet for two structural reasons rather than one marketing reason.

First, it is a brushless motor: there are no brushes rubbing on the rotor, and brushes are what generate most of the noise in a conventional motor. Second, it slows as it reaches its end limits — which is precisely where the slats stacking up make the most noise.

That two-speed behaviour applies even when you are not using the quiet mode, and it protects the mechanical parts as well as your ears. With compatible control points the RS 100 also offers a feather mode: a slow-running mode that makes opening and closing all but inaudible, which matters if the rest of the household is already asleep.

So which one

Give us the width and height of the opening and the material of the curtain, and the torque decides itself. The protocol is your call: io if you want feedback and a path towards a fully automated house, RTS or CAME if you want a simpler, less expensive radio link and no feedback.
