We carry out timber roof lantern repairs in Carmarthen and across the SA31 area. Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber.

What usually causes it?
Paint failure

Timber needs redecorating on a cycle; skipped cycles turn small repairs into big ones.
Covering Carmarthen and nearby
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Close by, we also cover Llanelli (13 miles), Ammanford (14 miles), Gorseinon (17 miles).
How much should it cost?
Guide price for timber roof lantern repairs: £395–£1,995 ex VAT (£474–£2,394 inc 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?
In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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.
