Signs of a Hidden Leak

Signs You May Have a Hidden Leak in Your Barking and Dagenham Property

Hidden leaks rarely announce themselves with a puddle. Across the borough’s mix of 1930s estate terraces and newer flats, these are the warning signs our engineers are called out to investigate most often.

 

Unexplained rise in water bills

A steady increase in your water bill with no change in usage is one of the clearest signs of a hidden leak — often in an underground supply pipe or beneath a solid floor.

Water bill spike

Damp patches, staining or peeling paint

Damp patches on walls or ceilings, discoloured plaster, or peeling paint in Becontree and Chadwell Heath’s older terraces often trace back to a slow leak in wall-chased or floor pipework rather than rising damp.

Visible damage

Warm patches on floors

A warm spot on an otherwise cool floor usually points to a leaking underfloor heating pipe or hot water supply pipe running beneath a solid floor — common in the borough’s 1930s estate housing.

Underfloor leaks

Sound of running water with no tap on

A persistent trickling or hissing sound when no fixture is in use is a strong indicator of a pressurised pipe leak, often audible near a riser cupboard in flats around Barking and Barking Riverside.

Audible leak

Barking and Dagenham leak detection context: The Becontree estate’s terraced houses, built to a consistent design across the 1920s and 30s, typically have supply pipes running beneath solid concrete floors laid decades ago. Non-invasive detection avoids the need to break up flooring speculatively, locating the leak to within a small area before any opening-up work begins.

Our Service

Our Leak Detection Service in Barking and Dagenham

A methodical, non-invasive process to find the exact source of a leak before any repair work begins — minimising disruption to your property.

 

1. Initial assessment

We review the symptoms — damp patches, bill spikes, pressure loss — and identify likely pipe runs based on your property's age and layout.

2. Thermal imaging

A thermal camera detects temperature differences in walls and floors caused by escaping water, narrowing the search area without any opening-up work.

3. Acoustic & tracer gas detection

Acoustic listening equipment and, where needed, tracer gas pinpoint the exact leak location, even behind walls or under solid floors.

4. Confirm & repair

Once located, we confirm the finding with you and provide a fixed price for the repair before any further work begins.

What Barking and Dagenham Customers Say

Water bill had crept up for months with no obvious cause. Thermal imaging found a leak under our Becontree kitchen floor within an hour — only had to lift a small section of tiling to fix it.

Wandsworth · Like-for-like combi replacement

Damp patch appeared on the lounge wall in our Dagenham terrace. The engineer used acoustic detection and traced it to a pinhole leak in a hidden pipe run — repaired the same day.
