In Mold, as everywhere, many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos and we'll tell you what we think has failed.

Signs you need uPVC roof lantern repairs
- Cracked cappings or ridge covers
- Rattling or whistling in wind
- Leaks at the ridge or eaves
Why it happens
Clip failure
Clip-on cappings can lose their grip and lift.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Mold 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.
From Wrexham to Mold is roughly 10 miles — all part of the Clwyd area we cover.
If you're just outside Mold, we also cover Buckley (2 miles), Deeside (5 miles), Flint (5 miles).
Guide prices for uPVC roof lantern repairs in Mold
Most uPVC roof lantern repairs jobs come in between £175 and £595 ex VAT (£210–£714 including 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.
