We carry out cracked lantern glass replacement in Sandown and across the PO36 area. A cracked pane in a roof lantern needs prompt attention because the glass is overhead.

Signs you need cracked lantern glass replacement
- A visible crack in the outer or inner pane
- A starburst from an impact point
- A crack running from an edge (often thermal stress)
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 Sandown 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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Sandown by arrangement: island work is planned around ferry access, and any travel or access costs are set out in your written quote before you commit.
Neighbouring places we cover include Ryde (5 miles), Newport, Isle of Wight (7 miles), Cowes (10 miles).
Guide prices for cracked lantern glass replacement in Sandown
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.

Cracked lantern glass replacement in Sandown: questions

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.

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.

Usually £295–£795 ex VAT per unit depending on size, spec and access, confirmed in writing before work starts.
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.
