Rooflight installers in Chiswick

Whatever the job in Chiswick, 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 use a rooflight fitting specialist

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.

Nearby towns we also cover

Our fitters cover all of Chiswick, including W4, W3 and W6, and travel on to Acton, Barnes and Hammersmith on the same basis. Nobody needs to visit us, because we come to the property for surveys and fitting. Dates are offered according to fitter availability, and travel is part of the written quote rather than an extra.

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 Chiswick

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

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.

How long does fitting take?

Fitting a rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

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.
