In Windsor, as everywhere, timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos and we'll tell you what we think has failed.

Signs you need timber roof lantern repairs
- Flaking or blistered paint on bars or eaves
- Putty or beads cracking and lifting
- Leaks at bar joints
Common causes we find
Paint failure
Once the paint film breaks, water gets into the end grain and joints.
No maintenance
Timber needs redecorating on a cycle; skipped cycles turn small repairs into big ones.
Covering Windsor and nearby
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
We cover Windsor as part of Berkshire, about 16 miles from Reading.
If you're just outside Windsor, we also cover Slough (2 miles), Egham (4 miles), Staines (5 miles).
How much should it cost?
Guide price for timber roof lantern repairs: £395–£1,995 ex VAT (£474–£2,394 inc VAT), per lantern. 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
