We carry out cracked lantern glass replacement in Monmouth and across the NP25 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
- Broken glass inside the room — keep everyone out of the area
Why it happens
Impact
Hail, falling branches or dropped tools.
Spontaneous breakage
Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.
Covering Monmouth and nearby
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Monmouth is around 20 miles from Newport, Gwent, and both are within our Gwent coverage.
Close by, we also cover Chepstow (12 miles), Abergavenny (13 miles), Pontypool (16 miles).
Guide prices for cracked lantern glass replacement in Monmouth
Most cracked lantern glass replacement jobs come in between £295 and £795 ex VAT (£354–£954 including 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 Wales?
In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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.

Cracked lantern glass replacement in Monmouth: questions
How do I get a price for cracked lantern glass replacement in Monmouth?
Send a few photos of the lantern and the problem, with your Monmouth postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Can you repair a lantern someone else installed in Monmouth?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Is it covered by home insurance?
Accidental damage often is; check your policy. We can provide a written quote and photos for your insurer.
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.
