We carry out cracked lantern glass replacement in Truro and across the TR1 area. A cracked pane in a roof lantern needs prompt attention because the glass is overhead.
What you might be seeing
- A visible crack in the outer or inner pane
- A starburst from an impact point
- A crack running from an edge (often thermal stress)
Common causes we find
Impact
Hail, falling branches or dropped tools.
Thermal stress
Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.
Roof lanterns in Truro
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.
Close by, we also cover Falmouth (8 miles), Redruth (8 miles), Newquay (10 miles).
Guide prices for cracked lantern glass replacement in Truro
Guide price for cracked lantern glass replacement: £295–£795 ex VAT (£354–£954 inc VAT), per glass unit. 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.

Send a few photos of the lantern and the problem, with your Truro postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

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.

Why did my glass crack on a sunny day?
Thermal stress — one part of the pane heats faster than another, often where it's shaded or chipped at the edge.
