Rooflight installers in Sunbury-on-Thames

Maybe the extension is nearly finished and the rooflight is still in its crate. Maybe the old dome on the kitchen roof has started to drip. Maybe you want daylight on a dark landing and wonder whether the roof can take a new opening. These are the kinds of job we take on in Sunbury-on-Thames and across Surrey: fit-only, replacement, new openings, roof lanterns and pitched roof windows. Builders and roofers can also bring us in for the rooflight part of a larger project, with the scope and price agreed in writing.

The details a specialist gets right

The joint between the rooflight and the roof covering is where most leaks start. On a flat roof that means turning the membrane up the kerb and terminating it properly under the frame. On a pitched roof it means the right flashing kit, lapped correctly with the tiles or slates. These details are fiddly and easy to rush on a busy build. Giving them to someone focused on fitting the rooflight, rather than treating it as one task among dozens, cuts the chance of a callback.

Fitting in Sunbury-on-Thames and beyond

Postcodes TW16, TW17 and KT12 are the core of our Sunbury-on-Thames coverage, but they are not the boundary. Addresses in Walton-on-Thames, West Molesey and Hampton 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.

Do you need permission in Sunbury-on-Thames?

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.

Questions about rooflight fitting in Sunbury-on-Thames

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 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.

Do you cover Sunbury-on-Thames?

Yes. Fitters travel to addresses in Sunbury-on-Thames and the surrounding districts, including TW16. 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.

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.
