We carry out roof lantern replacement in Cambridge and across the CB1 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.
Signs you need roof lantern replacement
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
Common causes we find
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
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.
If you're just outside Cambridge, we also cover Newmarket (13 miles), Ely (15 miles), Huntingdon (16 miles).
How much should it cost?
Typical range: £1,995–£4,995 ex VAT, which is £2,394–£5,994 with VAT, supplied and fitted. 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.
