In Cowbridge, 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
- Flaking or blistered paint on bars or eaves
- Soft timber when pressed
- Leaks at bar joints
Why it happens
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.
Covering Cowbridge and nearby
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.
Cowbridge is around 11 miles from Cardiff, and both are within our South Glamorgan coverage.
Close by, we also cover Llantwit Major (4 miles), Bridgend (7 miles), Barry (8 miles).
What should you expect to pay in Cowbridge?
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?
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.
