In Porthcawl, as everywhere, timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Dark staining or black lines along joints
- Putty or beads cracking and lifting
- Leaks at bar joints
What usually causes it?
Water trapped by beads
Glazing beads and putty can trap water against the timber if their seals fail.
No maintenance
Timber needs redecorating on a cycle; skipped cycles turn small repairs into big ones.
About Porthcawl and the CF36 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
We cover Porthcawl as part of Mid Glamorgan, about 6 miles from Bridgend.
Neighbouring places we cover include Bridgend (6 miles), Port Talbot (8 miles), Maesteg (9 miles).
What should you expect to pay in Porthcawl?
Typical range: £395–£1,995 ex VAT, which is £474–£2,394 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. 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.
