Leak Detection New Malden
Hidden water leaks in New Malden pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know New Malden buildings.
Local knowledge
New Malden housing, from a leak engineer's side
New Malden features dense Edwardian and Victorian terraced housing, with many properties having solid ground floors and original bathroom layouts positioned over living spaces. This means leaks from sanitaryware or waste pipes immediately affect ceilings below. The area has a mix of shallow and deeper foundations, influencing how leak water pools. Many homes have had loft conversions, adding pressure on existing plumbing stacks and creating new zones for potential leaks behind new stud walls.
Engineer's note
Don't wait if a ceiling stain appears or grows. In New Malden's terraces, water spreads quickly between floors. Call for immediate tracing and isolation.
Covered in New Malden

What fails here
Common leak problems in New Malden
01
Bathroom Waste Pipe Leaks
Original cast-iron waste stacks running through terraced properties corrode internally. Leaks often manifest as damp on downstairs ceilings, mimicking a roof leak.
02
Solid Floor Leak Spread
With many homes having solid ground floors, leaks from underfloor pipes can travel laterally, appearing far from the source. Isolating the exact branch is critical.
03
Loft Conversion Pressure Leaks
Adding an extra bathroom increases demand on old supply pipes. Weak joints upstairs can fail, causing water to channel down inside partition walls to the ground floor.
04
Shared Stack Leaks in Terraces
In some Victorian terraces, waste stacks are shared between properties. A leak can originate next door. We quickly determine responsibility with targeted testing.
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.
