Leak Detection Hendon
Hidden water leaks in Hendon pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Hendon buildings.
Local knowledge
Hendon housing, from a leak engineer's side
Hendon presents a mix of substantial inter-war semis, many with multiple bathrooms added over time, and large Edwardian villas now often serving as institutional buildings. Plumbing systems have been repeatedly modified, creating potential for crossed pipes and incorrect gradients. The area also has several 1960s-70s low-rise flat blocks with communal heating systems.
Engineer's note
We provide insurers with detailed modification histories for Hendon's institutional properties, linking leaks directly to specific upgrade phases for liability assessment.
Covered in Hendon

What fails here
Common leak problems in Hendon
01
Leaks in Institutional Plumbing Systems
Former large homes used as care homes or HMOs have high-usage, modified plumbing. Constant use stresses old joints and valves. We document usage patterns and system wear for insurers assessing business interruption claims.
02
Failed Lead-to-Copper Solder Joints
Partial upgrades in Edwardian villas often left lead pipes connected to copper with old-style solder joints. These degrade, causing leaks inside partition walls. Our thermal imaging identifies the exact joint failure for targeted access.
03
Communal Heating System Leaks
Low-rise blocks have shared pressurised heating loops. A leak in one flat's section can drain the entire system, causing widespread heating failure. We pressure-test individual sections to isolate the fault for the managing agent's insurer.
04
Blocked Soil Stacks in Multi-Storey Homes
Tall period properties with added en-suites overload original soil stack capacity, leading to recurrent blockages and overflow leaks. Our CCTV surveys show the inadequate gradient or capacity, supporting upgrade claims.
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.
