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 terraces of Edwardian and inter-war housing, with many properties having single-storey rear extensions. Plumbing layouts are often repetitive but modified piecemeal over decades, leading to inconsistent pipe materials and hidden junctions. Loft conversions are also common, adding pressure points to aging vertical stacks.
Engineer's note
We excel at unravelling the complex modification history of New Malden properties, producing a forensic audit of the plumbing system that gives insurers confidence in the claim's validity.
Covered in New Malden

What fails here
Common leak problems in New Malden
01
Multi-Material Pipework Junction Leaks
DIY alterations have created junctions between lead, copper, and plastic pipes that are prone to failure. We trace the entire system to map these incompatible joints. Our report details every non-compliant connection, substantiating the claim that the leak was a sudden failure of a modified system.
02
Back Addition & Kitchen Extension Leaks
Leaks under single-storey extensions are hard to access. We use borescope cameras via minimal access points to visually confirm the leak source and its cause. This video evidence satisfies insurer requirements for visual proof before authorising invasive repair work.
03
Shared Lateral Drain Leaks
Terraced properties often share lateral drains. We perform dye tests and CCTV surveys to establish which property's waste is escaping and where. This clear assignment of responsibility is essential for the insurer to pursue recovery from the correct policyholder or freeholder.
04
Loft Conversion Pressure Stress
Additional bathrooms in loft conversions increase demand on old iron rising mains. We pressure-test the entire vertical stack to identify weak points before they fail catastrophically, providing proactive evidence that can mitigate a larger future claim.
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.
Leak detection in New Malden — FAQs
How quickly can you attend a leak in New Malden?
Same-day appointments are usually available in New Malden and across Kingston upon Thames, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in New Malden?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know New Malden properties?
Yes — New Malden features dense terraces of Edwardian and inter-war housing, with many properties having single-storey rear extensions. Plumbing layouts are often repetitive but modified piecemeal over decades, leading to inconsistent pipe materials and hidden junctions. Loft conversions are also common, adding pressure points to aging vertical stacks.
Can you provide a report for my insurer?
Every New Malden detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
