You only pay the detection fee if we locate the leak.
All of Sutton
Same-day and next-day cover across the whole borough.
Insurer-ready reports
Trace & access documentation loss adjusters accept.
Multi-method survey
Acoustic, thermal, tracer gas and moisture on every visit.
Local knowledge
How Sutton properties leak
Sutton housing is dominated by 1930s semis, post-war family houses and low-rise flats. Chalky local water scales up older copper pipework; scale-weakened joints on hot-water circuits fail slowly and quietly under bathroom floors.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest — before we arrive.
Covered in Sutton
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance 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.
Common leak problems in Sutton
Scale-Induced Copper Pipe Joint Failure
Sutton's chalky water supply leads to significant limescale accumulation within older copper pipework. This scale buildup creates stress points at soldered joints, particularly on hot-water circuits. The gradual weakening causes slow, quiet leaks that often manifest under bathroom floors in 1930s semis and post-war houses before becoming visible.
Bathroom Subfloor Concealed Leaks
The prevalence of suspended timber floors in the borough's housing stock allows leaks from weakened hot-water pipe joints to travel undetected. Water pools within the floor cavity, damaging structural timber and underfloor insulation. This pattern requires precise location to minimise destructive investigation in family homes.
Low-Pressure Drip Accumulation
Slow leaks from scale-damaged joints often operate at very low pressure, producing minimal audible signature. Over weeks or months, this leads to substantial water accumulation and secondary damage like plaster degradation or mould. Standard inspection methods frequently miss these subtle failures.
Aged Hot-Water Circuit Degradation
The thermal cycling of hot-water systems accelerates scale formation in Sutton's water. Repeated expansion and contraction of copper pipes at scale-constricted joints creates microfractures. This results in systemic vulnerability across the heating and domestic hot-water circuits in properties from the mid-20th century.

How to Choose a Leak Detection Company in London: A Guide to Technology & Precision
Selecting a leak detection company requires evaluating their technology, methodology, and commercial sector expertise. Here's what to prioritise.
Leak detection in Sutton — FAQs
How quickly can you attend a leak in Sutton?
Same-day appointments are usually available in Sutton, and next-day almost always. If water is actively escaping, tell us when you book — live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Sutton is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes — trace and access reports documenting the cause, precise origin and affected areas are available for every Sutton detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Sutton do you cover?
All of it — including Sutton, Cheam, Carshalton, Wallington, Worcester Park. We cover every London borough, so coverage never depends on which side of a postcode line you live.
Why do so many Sutton and Carshalton homes get hot-water joint leaks?
The area sits on hard water, so scale gradually forms inside copper pipe and around soldered joints. On hot-water and heating circuits the repeated heating and cooling stresses those weakened joints, which is why pinhole and joint leaks in interwar Cheam and Carshalton semis often appear on hot feeds rather than cold ones. Thermal imaging works well on these warm circuits.
Can you tell if it is a leak or just damp in a 1930s Worcester Park house?
Often, yes. In 1930s and post-war Wallington and Worcester Park houses, damp can come from a slow pipe leak, condensation or ground moisture. We use moisture meters, thermal imaging on hot-water pipes and, where needed, acoustic tracing to check for an active leak before anyone lifts floors or replasters. A typical fixed detection fee is around £250 to £450.
