In Mold, as everywhere, commercial lanterns and atrium rooflights fail in the same ways as domestic ones, but access, safety and disruption matter more. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Leaks into trading or office areas
- Multiple lanterns on one roof needing a programme
- Managed buildings with planned maintenance needs
Common causes we find
Scale
More lanterns, more joints, more drainage to block.
Access
Roof access, edge protection and permits all affect the plan.
Roof lanterns in Mold
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.
Mold is around 10 miles from Wrexham, and both are within our Clwyd coverage.
If you're just outside Mold, we also cover Buckley (2 miles), Deeside (5 miles), Flint (5 miles).
How much should it cost?
Most commercial roof lantern repairs jobs come in between £495 and £2,995 ex VAT (£594–£3,594 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.
