Skylight repairs & leak fixes for Thamesmead: the essentials
We handle skylight repairs & leak fixes across Greater London, including Thamesmead. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Thamesmead, as anywhere, skylight repairs & leak fixes are the usual choice for rooflights that have stopped opening or started dripping.
From Thamesmead to Barking, Welling and Bexleyheath, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight repairs & leak fixes in Thamesmead
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.

Other services in Thamesmead
Skylight repairs & leak fixes in Thamesmead: questions
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
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 I need to be at home for the survey in Thamesmead?
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 Thamesmead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
