We carry out leak investigation and inspection in Stanley and across the DH9 area. Some leaks are obvious; many aren't.

Is it time for leak investigation and inspection?
- 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 Stanley and nearby
Freeze-thaw cycles open up tired sealant and gaskets faster than mild weather does. A spring check after a hard winter catches most problems before they leak.
From Durham to Stanley is roughly 8 miles — all part of the County Durham area we cover.

What should you expect to pay in Stanley?
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.
