Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Barnes (SW13) and we'll tell you which it is — with the price agreed in writing before any work.

About Barnes and the SW13 area
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.
Barnes is around 5 miles from Westminster, and both are within our Greater London coverage.
We also cover nearby Chiswick (1 mile), Putney (2 miles), Fulham (2 miles).
What should you expect to pay in Barnes?
Most cleaning and maintenance jobs come in between £95 and £245 ex VAT (£114–£294 including VAT), per visit. 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.
