What does skylight replacement in Sunbury-on-Thames involve?
Our skylight replacement service in Sunbury-on-Thames covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
Sunbury-on-Thames is around 14 km from Woking, and we survey and fit throughout that part of Surrey, including the TW16 district.

What to check first

Consents for skylight replacement in Sunbury-on-Thames
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about skylight replacement in Sunbury-on-Thames
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Do I need to be at home for the survey in Sunbury-on-Thames?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Sunbury-on-Thames?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
