Leak Detection Carshalton
Hidden water leaks in Carshalton pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Carshalton buildings.
Local knowledge
Carshalton housing, from a leak engineer's side
Carshalton's housing mix includes many post-war family houses with solid ground floors, as well as 1930s semis. The solid floors in later builds change leak behaviour, often causing water to travel to the perimeter or appear at damp-proof course level. Many properties have original immersion heaters and associated hot-water pipework, which are prime sites for scale accumulation. Identifying the precise leak path in these constructions is critical for insurer sign-off on remedial work.
Engineer's note
Our evidence clearly distinguishes internal plumbing leaks from external water ingress, a fundamental determination for insurance claim approval.
Covered in Carshalton
- Hidden leaks under floors and in walls

- Trace & access reports for insurance claims
What fails here
Common leak problems in Carshalton
01
Immersion Heater Circuit Leaks
Older immersion heater installations have long, often inaccessible, horizontal pipe runs that scale heavily. Leaks from these copper pipes can track within solid floor constructions. Our thermal imaging identifies the exact heat signature of the leaking hot water, providing the technical evidence insurers need to approve claim progression.
02
Solid Floor Leak Tracking
In post-war houses, leaks from pipes within or under solid floors can travel metres before appearing. We use tracer gas and moisture profiling to prove the water source is a specific pipe failure, not ground moisture, which is a standard requirement for insurer validation.
03
Garden Tap Feed Failures
The external feed to garden taps, often installed in post-war builds, is vulnerable to frost and scale. Leaks occur where the pipe enters the house under the solid floor. We isolate and pressure-test this line to confirm it as the source, documenting the process for the insurer's engineer.
04
First-Fall Soil Pipe Leaks
Leaks from the initial vertical drop of soil pipes behind ground-floor WCs are common in family houses. Our endoscopic camera surveys confirm the leak is from the pipe itself, not the pan connector, ensuring the correct cover is applied under the policy.
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 Carshalton — FAQs
How quickly can you attend a leak in Carshalton?
Same-day appointments are usually available in Carshalton 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 Carshalton?
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 Carshalton properties?
Yes — Carshalton's housing mix includes many post-war family houses with solid ground floors, as well as 1930s semis. The solid floors in later builds change leak behaviour, often causing water to travel to the perimeter or appear at damp-proof course level. Many properties have original immersion heaters and associated hot-water pipework, which are prime sites for scale accumulation. Identifying the precise leak path in these constructions is critical for insurer sign-off on remedial work.
Can you provide a report for my insurer?
Every Carshalton detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
