What do skylight repairs & leak fixes in Coulsdon involve?
For Coulsdon 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.
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 Coulsdon to Purley, Banstead and Wallington, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Actuator, motor and control repairs
- Planned maintenance visits
- Resealing and re-flashing
- Condensation diagnosis
- Glass unit replacement
- Misted unit replacement
- Leak tracing, not guesswork
What to check first
- Repairs are charged — the free survey applies to new installations
- Commercial roofs need access and fall protection
Planning and building rules for Coulsdon
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.

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.
