We carry out cracked lantern glass replacement in Colchester and across the CO1 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
- A crack running from an edge (often thermal stress)
What usually causes it?
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.
Roof lanterns in Colchester
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
From Chelmsford to Colchester is roughly 21 miles — all part of the Essex area we cover.
If you're just outside Colchester, we also cover Sudbury (13 miles), Clacton-on-Sea (13 miles), Witham (13 miles).
How much should it cost?
Most cracked lantern glass replacement jobs come in between £295 and £795 ex VAT (£354–£954 including 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.
