In Redruth, as everywhere, some leaks are obvious; many aren't. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Previous repairs haven't stopped the leak
- You're not sure if it's a leak or condensation
- You need a written report for a landlord, insurer or builder
Why it happens
More than one fault
Older lanterns often have two or three small failures.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
About Redruth and the TR15 area
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 Truro to Redruth is roughly 8 miles — all part of the Cornwall area we cover.
If you're just outside Redruth, we also cover Camborne (4 miles), Truro (8 miles), Falmouth (9 miles).
Guide prices for leak investigation and inspection in Redruth
Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including 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.
