We carry out leak investigation and inspection in Dagenham and across the RM10 area. Some leaks are obvious; many aren't.

What you might be seeing
- Previous repairs haven't stopped the leak
- The leak moves around or is intermittent
- You're not sure if it's a leak or condensation
Common causes we find
Hidden water paths
Water can travel along bars, decks and linings before it shows.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
Covering Dagenham 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.
We cover Dagenham as part of Greater London, about 13 miles from Westminster.
We also cover nearby Becontree (2 miles), Romford (2 miles), Hornchurch (2 miles).
Guide prices for leak investigation and inspection in Dagenham
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
