Leak Detection London — Find the Leak Without the Damage
Hidden leaks under floors, behind walls or below concrete can go undetected for months — causing structural damage, mould and inflated water bills. Our specialist leak detection engineers use thermal imaging cameras, acoustic listening equipment and tracer gas to pinpoint leaks precisely before opening anything up.

Thermal Imaging Leak Detection
Infrared cameras detect temperature anomalies caused by pipe leaks under floors or behind walls. Non-invasive, no drilling — the camera shows exactly where moisture is present.
Acoustic Leak Detection
Electronic listening equipment picks up the sound of water escaping pressurised pipes. Effective for buried pipes under concrete, tarmac or garden paths.
Tracer Gas Detection
A harmless mix of hydrogen and nitrogen is pumped into the pipe. The gas escapes at the leak point and is detected at surface level with a sensitive probe — accurate to within centimetres.
Swimming Pool & Underfloor Pipe Leaks
We locate leaks in underfloor heating systems, swimming pool pipework and buried supply pipes — services that require specialist equipment most plumbers don't carry.
Water Main Leak Location
If your water bill has spiked or you have unexplained damp patches, we can survey the incoming supply main from the meter to your stopcock to find any loss of pressure.
Report and Repair Option
After detection, we provide a written report with photos of the leak location. We can then carry out the repair work in the same visit or on a confirmed date.
Why Non-Invasive Leak Detection Matters
Traditional leak-finding by exploratory cutting is expensive, disruptive and often inaccurate — opening the wrong section of wall or floor means extra repair costs with no guarantee of finding the leak. Our specialist equipment locates the leak before we open anything, saving you significant time and money.
All detection surveys are followed by a written report with photographs of the leak location, moisture readings and recommended repair method. This report is accepted by insurers for escape-of-water claims.
