We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos from Falmouth (TR11) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
What usually causes it?
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Rot
Timber lanterns left unmaintained.
Covering Falmouth 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 Truro to Falmouth is roughly 8 miles — all part of the Cornwall area we cover.
Close by, we also cover Truro (8 miles), Redruth (9 miles), Camborne (11 miles).
Guide prices for roof lantern replacement in Falmouth
Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including VAT), supplied and fitted. 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.

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Will you tell me if repair is enough?
Yes. We'd rather do a repair that works than sell a lantern you don't need.
