About Barry and the CF62 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.
Barry is around 7 miles from Cardiff, and both are within our South Glamorgan coverage.
We also cover nearby Penarth (5 miles), Cardiff (7 miles), Cowbridge (8 miles).
How much should it cost?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. 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.
