We carry out cracked lantern glass replacement in Norwich and across the NR2 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 crack running from an edge (often thermal stress)
- 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.
Roof lanterns in Norwich
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We also cover nearby Great Yarmouth (18 miles), Lowestoft (22 miles), Thetford (27 miles).
Guide prices for cracked lantern glass replacement in Norwich
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.
