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.
