What we find, and fix
Every investigation starts the same way — establishing what's actually happening before anyone lifts a floor.
Water Mains & Central Heating Leaks
Detecting hidden leaks in underground water mains, central heating systems, and pipework before they cause further damage.
Internal & External Leak Detection
From leaks hidden in your walls to pipework buried underground, we locate the exact source so repairs can be targeted and precise.
Damp & Wet Patch Investigation
Not sure if it's a leak, rising damp, condensation, or humidity? We identify the true cause, so you're not paying to fix the wrong problem.
Leak Repairs
Where a repair is needed, we only excavate exactly where the problem is, no unnecessary disruption.
