We carry out leak investigation and inspection in Grangemouth and across the FK3 area. Some leaks are obvious; many aren't.

Signs you need leak investigation and inspection
- Previous repairs haven't stopped the leak
- The leak moves around or is intermittent
- 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 Grangemouth 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 Stirling to Grangemouth is roughly 11 miles — all part of the Stirling and Falkirk area we cover.
If you're just outside Grangemouth, we also cover Falkirk (3 miles), Bo'ness (4 miles), Larbert (4 miles).
How much should it cost?
Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including 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 Scotland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
