Common causes we find
More than one fault
Older lanterns often have two or three small failures.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
Covering Walthamstow and nearby
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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 Walthamstow as part of Greater London, about 8 miles from Westminster.
Close by, we also cover Leytonstone (2 miles), Tottenham (2 miles), Woodford Green (2 miles).
What should you expect to pay in Walthamstow?
Guide price for leak investigation and inspection: £145–£295 ex VAT (£174–£354 inc 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?
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.
