A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Cambridge (CB1) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- A starburst from an impact point
- 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.
About Cambridge and the CB1 area
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.
Neighbouring places we cover include Newmarket (13 miles), Ely (15 miles), Huntingdon (16 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?
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.
