Areas around Clapham we cover
Jobs across SW4, SW8 and SW11 are part of our normal cover for Clapham. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Battersea and Brixton are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Fit-only or supply and fit
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a conservation rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
Included in the work
- Rafters trimmed with timbers that suit the existing roof
- Position checked against any consent drawings or council conditions
- Slates or tiles made good around the frame with tidy cuts
- Glazing bar and frame detail — We check whether the council has asked for particular details, such as a central glazing bar or a dark frame colour.
- Energy and old roofs — We make sure the rooflight meets current energy rules while suiting an older roof build-up.
Fitting your conservation rooflight, step by step
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a conservation rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Do you need permission in Clapham?
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
Getting a price from photos
Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in SW4, and we can price it.
Common questions in Clapham
Do you make good inside after fitting?
Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Do you cover Clapham?
Yes. Fitters travel to addresses in Clapham and the surrounding districts, including SW4. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Got a unit waiting to go in, or need one sourced? Either way, start with your Clapham address and a couple of photos.
