Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Truro (TR1) and we'll tell you which it is — with the price agreed in writing before any work.

Covering Truro 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.
If you're just outside Truro, we also cover Falmouth (8 miles), Redruth (8 miles), Newquay (10 miles).
How much should it cost?
Typical range: £95–£245 ex VAT, which is £114–£294 with VAT, per visit. 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 England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
