Leak Detection Clapham
Hidden water leaks in Clapham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Clapham buildings.
Local knowledge
Clapham housing, from a leak engineer's side
Clapham is dominated by large, grand Victorian houses, many of which have been converted into spacious flats, often with modernised interiors. Despite refurbishments, the original underlying plumbing infrastructure frequently remains, with single supply pipes feeding multiple high-value units. The area also has mansion blocks with shared heating and water systems. Leaks here often involve significant damage due to the scale of properties, making precise source identification critical for high-value insurance claims.

What fails here
Common leak problems in Clapham
01
Leaks in Lateral Shared Pipes
In converted grand terraces, lateral pipes run under floorboards across flat boundaries. A leak under one flat's floor can drip into the ceiling void of the flat below. We pinpoint the exact leak location in the lateral run. Our report defines which property contains the faulty pipe section, a key fact for insurers apportioning repair and damage costs.
02
Mansion Block Pressure Issues
Clapham's mansion blocks have complex pumped water systems. Pressure fluctuations can cause joints in older sections to fail, leading to leaks in communal areas that affect private flats. We test system pressure and trace the leak to the specific failed component. This engineering assessment is required by insurers to approve system-wide repairs covered by building policies.
03
Leaks from En-Suite Additions
Many flats added en-suites during conversion, with new plumbing routed through voids. Leaks from these later installations can damage original features in neighbouring flats. We determine if the leak is from the original structure or a later addition. This distinction is crucial for insurers, as it affects whether the freeholder's or leaseholder's policy is responsible.
04
Concealed Heating Pipe Leaks
Original Victorian heating pipes, often buried in screed or behind cornices, corrode and leak slowly. This causes hidden structural damp that crosses property boundaries. We use thermal imaging and acoustic detection to find the leak without destructive searching. Our methodical approach provides the justified evidence insurers need to approve the invasive access required for repair.
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
