Skylight repairs & leak fixes for New Malden: the essentials
We handle skylight repairs & leak fixes across Greater London, including New Malden. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for skylight repairs & leak fixes include rooflights that have stopped opening or started dripping.
From New Malden to Surbiton, Kingston upon Thames and Morden, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in New Malden?
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. 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.

Questions about skylight repairs & leak fixes in New Malden
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.
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.
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Do I need to be at home for the survey in New Malden?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
