What do skylight repairs & leak fixes in Carmarthen involve?
For Carmarthen 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
Neighbouring towns include Llanelli (22 km) and Ammanford (23 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Glass unit replacement
- Planned maintenance visits
- Condensation diagnosis
- Actuator, motor and control repairs
- Upstand and membrane repairs
- Leak tracing, not guesswork
- Misted unit replacement
Before you order: points to check
- Repairs are charged — the free survey applies to new installations
- Commercial roofs need access and fall protection
Consents for skylight repairs & leak fixes in Carmarthen
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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. 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.

Skylight repairs & leak fixes in Carmarthen: questions
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.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Do I need to be at home for the survey in Carmarthen?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Carmarthen?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
