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 semis and purpose-built maisonettes from the inter-war and post-war periods. These properties commonly have galvanised steel internal pipework, which has a finite lifespan. The maisonettes often have communal boiler systems or complex heating layouts. The prevalence of steel pipes means internal rust buildup and sudden pinholing are a standard leak scenario, often occurring without obvious prior warning.
Engineer's note
A sudden water stain on a ceiling is an emergency—it often means a steel pipe has pinholed. We respond 24/7 to isolate it.
Covered in Greenford
- Hidden leaks under floors and in walls

What fails here
Common leak problems in Greenford
01
Galvanised Steel Pipe Pinholing
The original steel pipes in 1930s homes rust from the inside. Pinholing typically occurs at points of stress like elbows or near clips. A small, high-pressure jet can spray inside a wall or floor void for hours before damp appears. We use moisture detection to find the origin fast.
02
Maisonette Heating Leaks
In purpose-built maisonettes, heating pipes often run in concrete floor screeds or communal ducts. A leak here can affect another flat and is costly to access. We use thermal imaging from your unit to locate the hotspot before any destructive investigation.
03
Cold Feed Tank Leaks
Homes with older heating systems have a loft-mounted cold feed tank. A split tank or failed ball valve can flood a ceiling. The first sign is often a stained ceiling or water down a light fitting. Isolating the feed is an immediate priority.
04
Bath Panel Concealed Leaks
In standard 1930s bathroom layouts, bath pipes are boxed in. A leak from the tap connections or waste goes unseen until the floor or downstairs ceiling is damaged. We remove panels for direct inspection as a first step.
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 semis and purpose-built maisonettes from the inter-war and post-war periods. These properties commonly have galvanised steel internal pipework, which has a finite lifespan. The maisonettes often have communal boiler systems or complex heating layouts. The prevalence of steel pipes means internal rust buildup and sudden pinholing are a standard leak scenario, often occurring without obvious prior warning.
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.
