Leak Detection Greenford
Hidden water leaks in Greenford pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Greenford buildings.
Local knowledge
Greenford housing, from a leak engineer's side
Greenford features many 1930s semi-detached and detached houses alongside inter-war terraces. These properties typically have more spacious under-floor voids and longer pipe runs from the front stop-tap to rear kitchens and bathrooms. The pipework, while sometimes newer than in Edwardian homes, is still decades old and subject to wear. Leak detection here often involves navigating these longer, concealed runs.
Engineer's note
For Greenford's inter-war homes, our procedural leak tracing provides insurers with a clear audit trail from symptom to source along characteristic long pipe runs, ensuring claim accuracy.
Covered in Greenford

What fails here
Common leak problems in Greenford
01
Long Underfloor Run Leaks
The layout of 1930s semis means hot and cold pipes often run the full length of the house under the ground floor to serve rear additions. Leaks in the middle of these long runs are challenging to locate. We use strategic pressure testing to isolate sections. This methodical approach is documented to show the insurer we minimised unnecessary access points, controlling costs.
02
Leaks in Under-Stair Cupboard Pipework
A common design in these homes places the cold water tank feed, stop-tap, and manifold piping in an under-stairs cupboard. This cramped, often unheated space is a hotspot for condensation masking leaks and for pipework corrosion. Our inspection focuses on this critical hub. Identifying a leak source here often explains water damage in adjacent hallways and living rooms.
03
Garden Tap Feed Leaks
External tap feeds in 1930s properties often branch off under the kitchen floor and are rarely insulated. A frost-damaged pipe or faulty tap can leak back into the subfloor void, causing internal damp. We test these external branches as part of a full trace. Confirming or ruling out this source provides a complete picture for the insurer's claim file.
04
Original Galvanised Iron Pipe Failure
While less common than lead, some inter-war homes in Greenford retain original galvanised iron pipes, which corrode internally and can suddenly fail. The rust can obscure small leaks. Our engineers recognise the signs of this ageing material. Documenting the failure of obsolete pipework justifies a full replacement claim, preventing future incidents.
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 Greenford — FAQs
How quickly can you attend a leak in Greenford?
Same-day appointments are usually available in Greenford and across Ealing, 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 Greenford?
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 Greenford properties?
Yes — Greenford features many 1930s semi-detached and detached houses alongside inter-war terraces. These properties typically have more spacious under-floor voids and longer pipe runs from the front stop-tap to rear kitchens and bathrooms. The pipework, while sometimes newer than in Edwardian homes, is still decades old and subject to wear. Leak detection here often involves navigating these longer, concealed runs.
Can you provide a report for my insurer?
Every Greenford detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
