Professional Leak Detection in London

Hidden water leaks cause thousands of pounds in damage and significantly increase your water bills. Our specialists use the latest thermal imaging cameras and acoustic listening devices to pinpoint leaks to within centimetres - without digging or breaking.

Once we locate the leak, we provide a clear report and fixed-price repair quote. Many leaks are repaired on the same visit.

Signs You Have a Hidden Leak

  • Unexplained rise in water bills
  • Damp patches on walls, floors, or ceilings
  • Sound of running water when taps are off
  • Mould or mildew in unusual locations
  • Drop in water pressure
  • Warm spots on floors (underfloor leak)
  • Meter running when no water is in use

Technology We Use

Thermal Imaging

Infrared cameras detect temperature variations caused by water movement behind walls and under floors.

Acoustic Detection

Highly sensitive listening equipment hears the sound of water escaping pressurised pipes.

Tracer Gas

Safe hydrogen gas tracing locates leaks even under concrete slabs with pinpoint accuracy.

Frequently Asked Questions

How do you find a hidden water leak?
We use thermal imaging cameras to detect temperature variations caused by water movement, acoustic listening equipment to hear escaping water through pipes, and hydrogen tracer gas for leaks under concrete slabs.
Will you need to break up my floor to find the leak?
In most cases no. Our non-invasive methods locate leaks precisely so that only a small targeted access point is needed for repair - saving your floors, walls and budget.
How much does leak detection cost in London?
Leak detection costs from £150 for a thermal imaging survey to £350 for combined acoustic and tracer gas methods. A fixed price is always confirmed before work begins.
Can you detect leaks under concrete?
Yes - hydrogen tracer gas testing is specifically designed to locate leaks beneath concrete floors and driveways with pinpoint accuracy, without any breaking or excavation.
