What do skylight repairs & leak fixes in Brecon involve?
For Brecon 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Brecon, as anywhere, skylight repairs & leak fixes are the usual choice for rooflights that have stopped opening or started dripping.
From Brecon to Merthyr Tydfil, Ebbw Vale and Aberdare, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Brecon

Planning, building control and Brecon
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.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.

Common 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.
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.
How do I book a survey in Brecon?
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 Brecon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
