Leak Detection Feltham
Hidden water leaks in Feltham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Feltham buildings.
Local knowledge
Feltham housing, from a leak engineer's side
Feltham's housing stock is largely comprised of 1930s semi-detached homes, inter-war terraces, and larger post-war council and ex-council estates. Properties typically have suspended timber floors, older radiator systems, and a mix of original and replaced pipework. The prevalence of loft conversions and side-return extensions adds complexity to the plumbing layout. System pressure issues and ageing infrastructure are the predominant concerns.
Engineer's note
In Feltham's older stock with accessible sub-floors, our technical approach combines acoustic detection for active leaks with thermal imaging to trace historical water damage paths.
Covered in Feltham
- 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

Common leak problems in Feltham
01
Leaks Under Suspended Timber Floors
The void beneath ground-floor timber floors is a common route for leaking heating and water pipes. Water pools on the damp-proof membrane, causing rot in joists and floorboards. Inspection cameras and moisture probes are first used to assess conditions, followed by acoustic listening devices to locate the leak source from above.
02
Failing Feed-and-Expansion Tank Systems
Many older properties retain traditional open-vented heating systems with roof-space tanks. Overflows, ball-valve failures, and corrosion in the feed pipes are frequent leak sources. Thermal imaging of the ceiling below the tank can reveal moisture spread, while tracer gas can confirm leaks in inaccessible pipe runs.
03
Lead Communication Pipes
Like other parts of the borough, the original water service pipe from the mains to the property boundary is often lead. These can split, causing water loss into the front garden or under the driveway. We use pipe locators to trace the lead run and then ground microphones to listen for the distinctive sound of a leak under pressure.
04
Leaks at DIY Extension Junctions
Loft and side-return extensions often involve amateur plumbing ties into existing systems, creating weak points at new joints. These leaks are frequently intermittent and hard to trace. A combination of pressure decay testing and thermal imaging of the junction areas is used to identify the faulty connection.
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 Feltham — FAQs
How quickly can you attend a leak in Feltham?
Same-day appointments are usually available in Feltham and across Hounslow, 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 Feltham?
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 Feltham properties?
Yes — Feltham's housing stock is largely comprised of 1930s semi-detached homes, inter-war terraces, and larger post-war council and ex-council estates. Properties typically have suspended timber floors, older radiator systems, and a mix of original and replaced pipework. The prevalence of loft conversions and side-return extensions adds complexity to the plumbing layout. System pressure issues and ageing infrastructure are the predominant concerns.
Can you provide a report for my insurer?
Every Feltham detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
