Rooflight installers in Clapham

Rooflight jobs in Clapham usually start for one of four reasons. You have bought one and need it fitted. You have an old one that leaks, mists or has gone cloudy. You want more daylight and need a new opening cut. Or you are a builder who wants the rooflight part done by a specialist. We cover all four across Greater London. You might also want a lantern over a new kitchen, a sun tunnel for a dark hallway, or a hatch to reach the roof. Start with the service that matches your job.

Where rooflight jobs go wrong

Water has to go somewhere. Around a rooflight, the roof falls should carry it away from the kerb, not towards it. The glass itself needs enough pitch to shed rain and stop dirt settling. Condensation needs a path out of the frame. Get any of this wrong and the result is ponding, staining or drips months later. A specialist fitter checks these details as a matter of course, because they are the difference between a rooflight that works and one that turns into a repair job.

Covering Clapham and surrounding areas

Covering Clapham properly means covering the whole of it, house or business unit, across SW4, SW8 and SW11. Beyond the town, we take on jobs in Battersea (1 mile) and Brixton (1 mile) as standard. Each one gets the same survey or photo-based pricing, the same written quote, and the same fitting standard.

Planning and building rules in England

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.

Questions about rooflight fitting in Clapham

Can you fit the rooflight I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
