Leak Detection Stockwell
Hidden water leaks in Stockwell pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Stockwell buildings.
Local knowledge
Stockwell housing, from a leak engineer's side
Stockwell's housing includes a significant proportion of large local authority estates alongside Victorian and Edwardian terraces converted into flats. The estates have networks of communal plumbing, while the conversions suffer from ageing infrastructure. A particular challenge is the vertical spread of leaks in high-rise blocks and the difficulty of accessing plumbing that serves numerous individually owned leasehold flats, where establishing responsibility is complex.
Engineer's note
For Stockwell's estates, we provide insurers with clear diagrams of leak pathways in complex building systems, essential for determining liability across multiple leasehold and freeholder policies.
Covered in Stockwell

What fails here
Common leak problems in Stockwell
01
Leaks in Prefabricated Estate Plumbing
Some estates use prefabricated plumbing channels within concrete panels. Leaks inside these sealed channels are extremely hard to locate and access. We use specialised detection to find the leak without unnecessary demolition. Our report justifies the specific access points required, which insurers need to approve before funding complex, disruptive repairs.
02
Leak Spread in High-Rise Blocks
A leak on an upper floor in a tower block can travel down service ducts, electrical conduits, or external walls, appearing several floors below. We track the moisture pathway to its origin. This vertical trace report is vital for insurers to correctly assign the claim to the policy covering the flat where the leak originated, not where the damage manifested.
03
Failing Lead Communication Pipes
Many original lead communication pipes (between the main and the building) still serve Stockwell's older terraces. These can fracture, causing water to seep into foundations and neighbouring properties. We trace the leak to the communication pipe and document its condition. This evidence supports an insurer's case for recovery from the water utility if the leak is on their side of the boundary.
04
Balcony Drainage Leaks
Leaks from blocked or failed balcony drains on estates seep into the concrete structure, causing damp in flats below. We test drainage and use moisture meters to prove the source is the balcony above. This establishes that the repair is the responsibility of the freeholder or managing agent, guiding the insurer on which policy to claim against.
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.
