How we approach skylight repairs & leak fixes in Barry
Skylight repairs & leak fixes in Barry means leak tracing, resealing, actuator repairs and glass replacement. We cover the CF62 district and the rest of South Glamorgan, with a survey before any price is fixed.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Barry, as anywhere, skylight repairs & leak fixes are the usual choice for leaks, condensation, misted units and failed actuators.
Barry is around 11 km from Cardiff, and we survey and fit throughout that part of South Glamorgan, including the CF62 district.

Do you need permission in Barry?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Skylight repairs & leak fixes in Barry: questions
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.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Can you work alongside my builder in Barry?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Barry?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
