Leak Detection Willesden
Hidden water leaks in Willesden pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Willesden buildings.
Local knowledge
Willesden housing, from a leak engineer's side
Willesden features a high concentration of large, converted Victorian and Edwardian terraced houses, many now operating as HMOs or split into flats. These conversions often involved retrofitting multiple bathrooms and kitchens into original floorplans, creating complex, sometimes non-compliant plumbing routes. Original lead and iron pipework may still be in use or poorly connected to modern additions. The high occupancy in these conversions puts persistent strain on all parts of the water system.
Engineer's note
Our documentation of non-compliant alterations and material failures in Willesden's conversions provides insurers with the factual basis to approve repairs and pursue recovery from responsible landlords or contractors.

What fails here
Common leak problems in Willesden
01
Retrofit Bathroom Leaks
Bathrooms added in former bedrooms often rely on extended pipe runs and pumps. Leaks from poorly supported pipes or failing pump seals are common and can damage the structure and the flat below. We trace the leak to the specific retrofit installation.
02
Shared Kitchen Drain Blockages
In HMOs, shared kitchen sinks see heavy use, leading to frequent fat and waste blockages in older, narrow waste pipes. This causes overflows that leak into cupboards and underfloor spaces, requiring drain clearance and leak source verification.
03
Original Lead Pipe Fatigue
Surviving sections of original lead supply piping can develop pinhole leaks at joints or due to vibration. These leaks are often slow, causing hidden damp in walls. Our detection confirms the material and failure mode for the claim.
04
Illegal DIY Alterations
Unauthorised plumbing work by landlords or tenants, like moving a washing machine outlet, is prevalent. These alterations often feature substandard fittings that fail. Our report identifies non-compliant work, clarifying cause and responsibility.
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.
