Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos from Barnet (EN5) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need timber roof lantern repairs
- Flaking or blistered paint on bars or eaves
- Soft timber when pressed
- Putty or beads cracking and lifting
Why it happens
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 Barnet and nearby
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.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
Barnet is around 11 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Barnet, we also cover Potters Bar (3 miles), Borehamwood (3 miles), Finchley (3 miles).
What should you expect to pay in Barnet?
Typical range: £395–£1,995 ex VAT, which is £474–£2,394 with 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?
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.
