We carry out timber roof lantern repairs in Isleworth and across the TW7 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
- 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.
Water trapped by beads
Glazing beads and putty can trap water against the timber if their seals fail.
Covering Isleworth 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.
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 Isleworth as part of Greater London, about 9 miles from Westminster.
Close by, we also cover Hounslow (1 mile), Heston (2 miles), Richmond (2 miles).
Guide prices for timber roof lantern repairs in Isleworth
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
