Leak Detection Hanwell
Hidden water leaks in Hanwell pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Hanwell buildings.
Local knowledge
Hanwell housing, from a leak engineer's side
Hanwell is characterised by long rows of Edwardian and late-Victorian terraces, many with distinctive bay windows. Properties often have narrow frontages, concentrating plumbing services in a tight central zone. The proximity of the bathroom to the kitchen stack, with pipes running in boxing or between floors, is typical. Original cast iron waste stacks are still prevalent and a known failure point for internal leaks.
Engineer's note
A damp patch on an internal wall or ceiling needs immediate investigation—it's often a cast iron stack leaking foul water.
Covered in Hanwell

What fails here
Common leak problems in Hanwell
01
Cast Iron Stack Failures
Original cast iron soil and waste stacks rust from the inside out. A failure often occurs at a collar joint in the boxing between floors, leaking foul water into the wall. The first sign is usually damp staining down an internal wall, not a visible pipe.
02
Bay Window Roof Leaks Misdiagnosed
Damp in a bay window ceiling is often assumed to be a roof leak. However, it can be a leaking joint on the rising main or a radiator pipe that runs in the cavity of the bay. We use tracing equipment to confirm the source is plumbing, not roofing.
03
Bathroom Waste Leaks
Close-proximity plumbing means a leak from a bath waste or shower trap can quickly seep into the kitchen ceiling below. The sealant around bath edges is often blamed, but the leak may be from the waste pipe itself. We perform water tests to isolate the exact fitting.
04
Front-to-Back Pipe Runs
With narrow homes, cold water pipes often run from the front stop-tap, under the ground floor, to a back kitchen. A leak anywhere on this long run can undermine ground floor stability. We trace the entire route with acoustic listening devices.
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 Hanwell — FAQs
How quickly can you attend a leak in Hanwell?
Same-day appointments are usually available in Hanwell 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 Hanwell?
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 Hanwell properties?
Yes — Hanwell is characterised by long rows of Edwardian and late-Victorian terraces, many with distinctive bay windows. Properties often have narrow frontages, concentrating plumbing services in a tight central zone. The proximity of the bathroom to the kitchen stack, with pipes running in boxing or between floors, is typical. Original cast iron waste stacks are still prevalent and a known failure point for internal leaks.
Can you provide a report for my insurer?
Every Hanwell detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
