In Dolgellau, as everywhere, aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • Leaks at bars or ridge
  • Misted units
  • Corrosion at cut edges or fixings in coastal areas

Common causes we find

Worn gaskets

Gaskets do the weatherproofing; they harden and shrink with age.

Thermal movement

Aluminium moves with temperature; seals and fixings take the strain.

Roof lanterns in Dolgellau

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.

Dolgellau is around 35 miles from Bangor, Gwynedd, and both are within our Gwynedd coverage.

Close by, we also cover Machynlleth (11 miles), Porthmadog (16 miles), Aberystwyth (24 miles).

What should you expect to pay in Dolgellau?

Guide price, per lantern£195–£695 ex VAT£234–£834 inc VAT

Most aluminium roof lantern repairs jobs come in between £195 and £695 ex VAT (£234–£834 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.
