Water Leak Detection

A hidden water leak rarely announces itself. It shows up as a water bill that has crept upward, a damp patch that keeps returning no matter how often it dries out, a warm spot on a cold floor, or a water meter that keeps turning when every tap in the house is off. Left alone, a small pinhole in a supply pipe can shift thousands of litres a month and quietly damage floors, walls and foundations.

How we find hidden water leaks

We locate leaks non-invasively, with no exploratory digging and no ripping out kitchens on a hunch. A typical survey combines:

• Acoustic profiling. Ground microphones and listening equipment pick up the distinct hiss of pressurised water escaping underground.
• Thermal imaging. Infrared cameras reveal the temperature signature a leak leaves in floors and walls.
• Tracer gas. A safe hydrogen and nitrogen mixture is introduced into the pipe and detected at the surface directly above the leak.
• Pressure and flow testing. Sections of pipework are isolated in turn to confirm which run is losing water before any pinpointing begins.
• Moisture mapping. Calibrated meters trace the spread of moisture back to its source, separating leaks from condensation and penetrating damp.

Signs you have a hidden leak

• Unexplained increase in your water bill or meter readings
• The meter dial moves with all outlets turned off
• Damp patches, lifting flooring or peeling paint that keeps coming back
• The sound of running water when nothing is in use
• Low water pressure at taps that used to run strongly
• Warm areas on solid floors, often a hot water or heating pipe

What you get

Every survey ends with a clear verbal explanation on the day and a written report with photographs, thermal images and a marked leak location: the same report your insurer needs for a trace and access claim. Because we come from a plumbing and heating background, we can usually repair the leak as well as find it.
