We carry out leak investigation and inspection in Woodford Green and across the IG8 area. Some leaks are obvious; many aren't.

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
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 Woodford Green 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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
We cover Woodford Green as part of Greater London, about 10 miles from Westminster.
Close by, we also cover Chingford (2 miles), Walthamstow (2 miles), Leytonstone (3 miles).
How much should it cost?
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.
