Leak Detection in Barnet

Finding leaks in Barnet homes

Barnet has a wide mix of homes, from Victorian and Edwardian terraces around the High Street to inter-war semis and larger detached properties towards the edges of town. Older pipework in the earlier houses is a common source of slow, hidden leaks, while newer extensions and loft conversions add extra runs of pipe that are easy to forget about until a stain appears.

Many Barnet homes have central heating pipes running under solid or screeded floors. A drop in boiler pressure, or a damp patch on a ground-floor wall with no obvious cause, often points to a heating leak that cannot be seen from the surface. Thermal imaging and pressure testing let us trace it without lifting floors unnecessarily.

Whether it is a wet patch on a ceiling, a rising water bill, or a suspected leak on the supply pipe between the street and your house, we start by working out what is actually happening before any digging or opening up is suggested.

Problems we commonly investigate in Barnet

• Central heating leaks under floors
• Ceiling stains from bathroom or loft pipework
• Underground supply pipe leaks between the street and the house
• Damp patches that may or may not be a leak

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.
