Leak Detection Cheam
Hidden water leaks in Cheam pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Cheam buildings.
Local knowledge
Cheam housing, from a leak engineer's side
Cheam is characterised by spacious 1930s semis and larger detached homes, often with extended bathroom suites and additional en-suites added over time. These modifications have increased the complexity of original hot-water circuits, placing more strain on scaled joints. Properties frequently have larger roof spaces and longer pipe runs from tanks to outlets, increasing the potential for concealed leaks. The architectural value of these homes makes minimally invasive leak detection a priority for both homeowners and insurers.
Engineer's note

What fails here
Common leak problems in Cheam
01
Extended Pipework Stress
Additions like en-suites have extended original hot-water circuits beyond their designed capacity, accelerating failure at old, scaled joints. We document the system layout and pinpoint the failure at the original, insured plumbing, not the newer extensions, to satisfy insurer scrutiny.
02
Tank Feed Leaks in Lofts
Cold feed pipes from header tanks in large loft spaces are prone to scale buildup and subsequent pinhole leaks, which can go unnoticed until ceiling damage appears. Our loft inspections provide photographic evidence of the active leak source, a prerequisite for most insurer-approved repairs.
03
Under-Bath Leaks in Period Homes
Original cast-iron baths in Cheam homes are often on raised panels, concealing the pipework below. Leaks from scaled joints here damage floorboards and ceilings. We use targeted access to expose only the failed joint, creating a documented, justified trace and access record for cost recovery.
04
Lead-to-Copper Junction Failure
Some older Cheam properties have original lead mains connected to copper internal systems. The galvanic reaction at these junctions, exacerbated by local scale, causes corrosion. We identify this specific failure mode in our report, which is key for insurers to confirm it's a sudden plumbing failure, not excluded gradual deterioration.
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 Cheam — FAQs
How quickly can you attend a leak in Cheam?
Same-day appointments are usually available in Cheam and across Sutton, 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 Cheam?
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 Cheam properties?
Yes — Cheam is characterised by spacious 1930s semis and larger detached homes, often with extended bathroom suites and additional en-suites added over time. These modifications have increased the complexity of original hot-water circuits, placing more strain on scaled joints. Properties frequently have larger roof spaces and longer pipe runs from tanks to outlets, increasing the potential for concealed leaks. The architectural value of these homes makes minimally invasive leak detection a priority for both homeowners and insurers.
Can you provide a report for my insurer?
Every Cheam detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
