Boiler constantly losing pressure

Mould or mildew growth
Warm spots on floor (underfloor heating)

How We Find Leaks Without Damage

We use industry-leading non-destructive technology to pinpoint the exact location of your leak.

Acoustic Detection
Using highly sensitive microphones to listen for the precise frequency of escaping water.
Thermal Imaging
Infrared cameras detect temperature differences caused by damp or hot water leaks.
Tracer Gas
Safe gas is pressurized into the system; sniffer devices detect where it escapes.
Mains Tracing
Locating underground supply pipes and pin-pointing leaks in external mains.
Moisture Mapping
Creating a map of damp levels to trace the leak back to its source non-intrusively.
Detailed Reporting
Comprehensive written report including photos and recommendations for insurance.
