What do skylight repairs & leak fixes in Llanelli involve?
For Llanelli 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for skylight repairs & leak fixes include rooflights that have stopped opening or started dripping.
Llanelli is the main town we list in Dyfed; we also cover nearby Gorseinon and Swansea.

Planning, building control and Llanelli
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight repairs & leak fixes in Llanelli
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
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 Llanelli?
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 Llanelli?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
