Skylight repairs & leak fixes in Wandsworth: what is involved?
Our skylight repairs & leak fixes service in Wandsworth covers leak tracing, resealing, actuator repairs and glass replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
From Wandsworth to Battersea, Chelsea and Fulham, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight repairs & leak fixes in Wandsworth
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Skylight repairs & leak fixes in Wandsworth: questions
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.
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
