In Cowbridge, as everywhere, commercial lanterns and atrium rooflights fail in the same ways as domestic ones, but access, safety and disruption matter more. Send photos and we'll tell you what we think has failed.

About Cowbridge and the CF71 area
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
Cowbridge is around 11 miles from Cardiff, and both are within our South Glamorgan coverage.

What should you expect to pay in Cowbridge?
Typical range: £495–£2,995 ex VAT, which is £594–£3,594 with VAT, per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Wales?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
