In Dolgellau, 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
- Insurance or landlord requirement for a report
Why it happens
Scale
More lanterns, more joints, more drainage to block.
Access
Roof access, edge protection and permits all affect the plan.
Covering Dolgellau 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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
From Bangor, Gwynedd to Dolgellau is roughly 35 miles — all part of the Gwynedd area we cover.
If you're just outside Dolgellau, we also cover Machynlleth (11 miles), Porthmadog (16 miles), Aberystwyth (24 miles).
What should you expect to pay in Dolgellau?
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?
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.
