What do skylight repairs & leak fixes in Hampstead involve?
For Hampstead homes and buildings we offer skylight repairs & leak fixes: leak tracing, resealing, actuator repairs and glass replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Typical uses for skylight repairs & leak fixes include leaks, condensation, misted units and failed actuators.
Hampstead sits about 1 km from Kilburn and 2 km from Highgate, and we cover the whole NW3 postcode district and the roads in between.
Specification options
- Condensation diagnosis
- Glass unit replacement
- Resealing and re-flashing
- Upstand and membrane repairs

Before you order: points to check
- Commercial roofs need access and fall protection
- Repairs are charged — the free survey applies to new installations
Do you need permission in Hampstead?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight repairs & leak fixes in Hampstead
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
Do I need to be at home for the survey in Hampstead?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Hampstead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
