Leak Detection Wallington
Hidden water leaks in Wallington pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Wallington buildings.
Local knowledge
Wallington housing, from a leak engineer's side
Wallington features a high proportion of interwar and post-war semis, many with original but updated heating systems. A common trait is the boxing-in of pipework in corners of kitchens and bathrooms, which conceals ageing joints. Properties also have a notable number of original ground-floor cloakrooms, adding complexity to the cold-water feed network. These hidden pipe runs necessitate systematic leak detection to avoid unnecessary damage during investigation, a key concern for cost-controlled insurance claims.
Engineer's note
We focus on pinpoint accuracy to limit investigative damage, keeping trace and access costs within typical policy allowances and streamlining your claim.
Covered in Wallington

What fails here
Common leak problems in Wallington
01
Boxed-In Pipe Leaks
Pipework concealed in built-in boxing is a frequent leak source, as scale-weakened joints fail out of sight. We use acoustic amplifiers to listen for leaks through the boxing, allowing us to specify a single, precise access point. This minimises repair costs and provides insurers with a justified trace and access invoice.
02
Cloakroom Supply Leakage
The cold feed to ground-floor cloakrooms often branches off long, scaled main runs. Leaks at these T-joints slowly dampen internal walls. Our moisture meters map the damp pattern back to the source, creating the objective data required to prove the leak's origin to an insurer's loss adjuster.
03
Partial System Re-pipes
Some homes have had partial re-pipes, leaving old, scaled sections connected to new pipework. Failure occurs at the interface. We map the entire system to identify the failed section as part of the original, insured installation, which is critical for claim acceptance.
04
Leaking Isolating Valves
Old, rarely-used isolating valves on bathroom feeds seize and then leak from their stems when finally operated. We document the valve's age and location on the original system, demonstrating the failure was sudden and unforeseen, not a maintenance issue.
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 Wallington — FAQs
How quickly can you attend a leak in Wallington?
Same-day appointments are usually available in Wallington 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 Wallington?
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 Wallington properties?
Yes — Wallington features a high proportion of interwar and post-war semis, many with original but updated heating systems. A common trait is the boxing-in of pipework in corners of kitchens and bathrooms, which conceals ageing joints. Properties also have a notable number of original ground-floor cloakrooms, adding complexity to the cold-water feed network. These hidden pipe runs necessitate systematic leak detection to avoid unnecessary damage during investigation, a key concern for cost-controlled insurance claims.
Can you provide a report for my insurer?
Every Wallington detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
