We carry out timber roof lantern repairs in Thamesmead and across the SE28 area. Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber.

Signs you need timber roof lantern repairs
- Dark staining or black lines along joints
- Putty or beads cracking and lifting
- Leaks at bar joints
Why it happens
Paint failure
Once the paint film breaks, water gets into the end grain and joints.
Water trapped by beads
Glazing beads and putty can trap water against the timber if their seals fail.
Roof lanterns in Thamesmead
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.
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.
We cover Thamesmead as part of Greater London, about 11 miles from Westminster.
Close by, we also cover Barking (3 miles), Welling (3 miles), Becontree (3 miles).
How much should it cost?
Most timber roof lantern repairs jobs come in between £395 and £1,995 ex VAT (£474–£2,394 including 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.
