We carry out cracked lantern glass replacement in Tewkesbury and across the GL20 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 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
Common causes we find
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 Tewkesbury and the GL20 area
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.
Tewkesbury is around 9 miles from Gloucester, and both are within our Gloucestershire coverage.
If you're just outside Tewkesbury, we also cover Cheltenham (7 miles), Gloucester (9 miles), Great Malvern (11 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.
