In Wimbledon, as everywhere, a cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos and we'll tell you what we think has failed.

Is it time for cracked lantern glass replacement?
- A visible crack in the outer or inner pane
- A crack running from an edge (often thermal stress)
- Broken glass inside the room — keep everyone out of the area
What usually causes it?
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 Wimbledon and nearby
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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
From Westminster to Wimbledon is roughly 6 miles — all part of the Greater London area we cover.

What should you expect to pay in Wimbledon?
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?
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.

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.

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.
