We carry out cracked lantern glass replacement in Daventry and across the NN11 area. A cracked pane in a roof lantern needs prompt attention because the glass is overhead.
Is it time for cracked lantern glass replacement?
- A starburst from an impact point
- A crack running from an edge (often thermal stress)
- 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 Daventry and nearby
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
From Northampton to Daventry is roughly 12 miles — all part of the Northamptonshire area we cover.
If you're just outside Daventry, we also cover Rugby (9 miles), Northampton (12 miles), Leamington Spa (15 miles).
How much should it cost?
Typical range: £295–£795 ex VAT, which is £354–£954 with 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?
In England, 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, so we set out the route in writing first. 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.
