Skylight repairs & leak fixes in Dinas Powys: what is involved?
Our skylight repairs & leak fixes service in Dinas Powys covers leak tracing, resealing, actuator repairs and glass replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.

From Dinas Powys to Penarth, Cardiff and Barry, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Dinas Powys
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. 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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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 charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Can you work alongside my builder in Dinas Powys?
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 Dinas Powys?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
