Rooflight installers in Norbury

Whatever the job in Norbury, the route to a price is the same. Fit-only work is usually priced from your photos and measurements. Supply and fit, replacements and new openings get a free survey. After that, a written quote sets out the scope and the price before anything is booked. The range covers rooflights, lanterns, pitched roof windows, conservation units, upstands and kerbs, and trade fitting across Greater London. Leak investigation is available too, as a charged visit with its price confirmed before you book.

Why the fitting matters as much as the unit

Builders run many trades at once, and the rooflight often gets squeezed in between the roofer and the plasterer. That is when corners get cut: an upstand built a little low, sealant applied in damp conditions, a reveal left rough. Bringing in a fitting specialist for that one stage means someone is focused on it alone, following the maker's instructions, with time set aside to finish the inside properly. The builder keeps control of the programme, and the rooflight gets proper attention.

Postcodes and places we cover

Postcodes SW16, SE27 and SE19 are the core of our Norbury coverage, but they are not the boundary. Addresses in Upper Norwood, Streatham and Tooting are handled in just the same way, with fitters travelling to each one and travel costs built into the quote before you agree to anything. If you are unsure which side of a boundary you fall on, the full postcode settles it.

Planning and building control

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Questions about rooflight fitting in Norbury

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

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.

What if my roof opening is the wrong size for the rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Will my new rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
