We carry out timber roof lantern repairs in Streatham and across the SW16 area. Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber.

What you might be seeing
- Flaking or blistered paint on bars or eaves
- Dark staining or black lines along joints
- 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 Streatham and nearby
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
Streatham is around 5 miles from Westminster, and both are within our Greater London coverage.
We also cover nearby Mitcham (2 miles), Brixton (3 miles), Wimbledon (3 miles).
How much should it cost?
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.
