We carry out cracked lantern glass replacement in Horsham and across the RH12 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
Thermal stress
Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.
Spontaneous breakage
Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.
About Horsham and the RH12 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Horsham as part of West Sussex, about 25 miles from Chichester.
If you're just outside Horsham, we also cover Crawley (7 miles), Horley (11 miles), Haywards Heath (11 miles).
Guide prices for cracked lantern glass replacement in Horsham
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?
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.
