In Rhyl, as everywhere, the upstand, or kerb, is the raised frame the lantern sits on. Send photos and we'll tell you what we think has failed.

Is it time for upstand and kerb repairs?
- Soft or spongy timber at the base of the lantern
- Roof membrane not lapped up the kerb, or peeling off it
- Cold, damp or mouldy lining around the opening
What usually causes it?
Kerb too low
If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.
Rotten timber
Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.
Covering Rhyl and nearby
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.
Rhyl is around 28 miles from Wrexham, and both are within our Clwyd coverage.
We also cover nearby Prestatyn (4 miles), Abergele (4 miles), Colwyn Bay (10 miles).
How much should it cost?
Guide price for upstand and kerb repairs: £395–£1,295 ex VAT (£474–£1,554 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.
