What you might be seeing

  • The leak moves around or is intermittent
  • You're not sure if it's a leak or condensation
  • You need a written report for a landlord, insurer or builder

Common causes we find

Hidden water paths

Water can travel along bars, decks and linings before it shows.

More than one fault

Older lanterns often have two or three small failures.

Covering Mitcham and nearby

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

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.

Mitcham is around 7 miles from Westminster, and both are within our Greater London coverage.

Neighbouring places we cover include Morden (1 mile), Wimbledon (2 miles), Streatham (2 miles).

How much should it cost?

Guide price, per visit£145–£295 ex VAT£174–£354 inc VAT

Typical range: £145–£295 ex VAT, which is £174–£354 with 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.
