Skylight repairs & leak fixes for Llantwit Major: the essentials
We handle skylight repairs & leak fixes across South Glamorgan, including Llantwit Major. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Llantwit Major, as anywhere, skylight repairs & leak fixes are the usual choice for leaks, condensation, misted units and failed actuators.
We work across South Glamorgan, including Llantwit Major, and in neighbouring towns such as Cowbridge and Bridgend. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Llantwit Major
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. 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.

Questions about skylight repairs & leak fixes in Llantwit Major
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 you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
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 work alongside my builder in Llantwit Major?
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 Llantwit Major?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
