Walk-on rooflight installation in Isleworth

Isleworth guide prices

Guide ranges for supply & fit. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

Coverage in and around Isleworth

Jobs across TW7, TW3 and TW5 are part of our normal cover for Isleworth. 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 Hounslow and Heston 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

Your unit or ours, the fitting standard is the same. For supply and fit we choose a walk-on rooflight to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

What the job includes

• Perimeter joints sealed and the waterproofing lapped as the maker shows
• Unit bedded and fixed so it sits level with the finished surface
• Drainage around the unit checked so water does not lie on the glass
• Structural calculations — We need structural calculations for the glass and its support before a walk-on job goes ahead.
• Drainage around the glass — We check how water will drain from the terrace around the unit.

Fitting your walk-on rooflight, step by step

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a walk-on rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days.

Do you need permission in Isleworth?

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Help us quote accurately

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as TW7.
