How we approach skylight repairs & leak fixes in Dover
Skylight repairs & leak fixes in Dover means leak tracing, resealing, actuator repairs and glass replacement. We cover the CT16 district and the rest of Kent, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
From Dover to Folkestone, Deal and Canterbury, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Dover
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Skylight repairs & leak fixes in Dover: questions
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
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.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
How do I book a survey in Dover?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Dover?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
