SOUND FAMILIAR?

Signs You Might Have a Hidden Leak

Not all leaks are obvious. These are the most common signs we’re called out for across London.

Unexplained High Water Bills

A sudden jump in your water bill with no change in usage often points to an underground or hidden leak.

Damp Patches or Warm Spots

Damp patches on walls or floors, or warm areas on flooring, can indicate a leaking hot water pipe.

Water Meter Still Spinning

If your meter keeps moving with every tap and appliance off, water is escaping somewhere in the system.

Musty Smells or Mould

Persistent damp smells or mould growth, especially in areas without obvious water use, often trace back to a slow leak.

HOW WE FIND IT

Non-Invasive Detection Methods

We use professional detection equipment to locate leaks precisely, minimising disruption to your property.

Acoustic Detection

Sensitive listening equipment picks up the sound of water escaping from pressurised pipes, even behind walls or under floors.

Pressurised pipe leaks

Thermal Imaging

Thermal cameras detect temperature differences caused by leaking water, useful for spotting leaks in walls, floors and ceilings.

Hidden & slow leaks

Tracer Gas Detection

A safe, non-toxic tracer gas is passed through the pipework and detected at the surface, pinpointing leaks with high accuracy.

Underground & complex leaks
