Leak Detection in Cockfosters

Finding leaks in Cockfosters homes

Cockfosters is largely suburban, with many inter-war semi-detached and detached houses, plus blocks of flats around the station. Homes of this age often have original or early replacement pipework, and heating systems that have been altered several times over the decades.

A common call-out here is a slow heating leak under a ground-floor floor, where the first sign is a boiler that keeps losing pressure. Because the pipe is buried in screed or beneath boards, it can be hard to locate by guesswork, which is where thermal imaging and pressure testing help.

We also look at leaks on the supply pipe outside the house, which can run for a long way between the boundary and the property, and at leaks in flats where shared pipework serves several homes.

Problems we commonly investigate in Cockfosters

• Boiler pressure that keeps dropping
• Buried heating pipe leaks under floors
• Supply pipe leaks between boundary and house
• Water stains in flats served by shared pipework

What we offer

• 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.

We use thermal imaging, tracer gas, moisture mapping, pressure testing, dye testing and salt analysis, choosing the method that suits your property. See how our methods work.
