Local knowledge
How Ealing properties leak
Ealing housing is dominated by Edwardian terraces, 1930s semis and purpose-built maisonettes. Edwardian houses here often keep original lead or iron rising mains; corrosion at the stop-tap joint under the front hall floor is a common find.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest — before we arrive.
Covered in Ealing
- 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
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.
What fails here
Common leak problems in Ealing
01
Corrosion at Stop-Tap Joint
In Edwardian terraces, the original iron or lead rising mains often corrode at the junction with the stop-tap beneath the front hall floorboards. This creates a persistent, slow leak that can saturate the subfloor timber and joists. Access typically requires lifting original floorboards, and we use acoustic listening devices to pinpoint the exact joint under pressure.
02
Maisonette Supply Pipe Leaks
Purpose-built maisonettes from the 1930s often have shared supply pipes that run through ceiling voids between flats. Corrosion at connection points or splits in copper piping from movement are common. Tracer gas testing is particularly effective here, as it can travel through wall cavities and floor voids to identify the precise flat of origin without invasive demolition.
03
Semis' External Pipework Failure
1930s semis frequently have original external soil stacks and overflows. Frost damage and degradation of iron or cast iron pipes lead to leaks at brackets or joints. Thermal imaging surveys from inside adjacent rooms can reveal cold spots and moisture trails, mapping the extent of water ingress through the brickwork.
04
Concealed Heating Pipe Leaks
In all Ealing property types, original or retrofitted central heating pipes are often concealed under suspended timber floors. Pin-hole leaks from corrosion or failed solder joints drip onto subfloor materials. We employ a combination of acoustic listening for pressurised systems and precise moisture mapping with hygrometers to trace the leak path back to its source.
From the forums
Leak Detection in Ealing's Terraces, Semis and Mansion Flats
Across housing and DIY forums, Ealing residents describe a fairly consistent set of problems for a borough of Edwardian terraces, 1930s semis, mansion flats and later maisonettes. A common theme is old lead or iron rising mains that have corroded over decades, sometimes weeping slowly under solid hall floors where the stop-tap sits, so damp appears with no obvious source. People in converted flats often mention shared or unclear supply pipes, which makes it hard to tell whose leak it is or where the run goes. Others report struggling to separate a genuine water leak from rising or penetrating damp, and worry about lifting original tiled or concrete floors unnecessarily. The general advice that recurs is to locate the leak before opening anything up, rather than guessing and digging.

How to Choose a Leak Detection Company in London: A Guide to Technology & Precision
Selecting a leak detection company requires evaluating their technology, methodology, and commercial sector expertise. Here's what to prioritise.
Leak detection in Ealing — FAQs
How quickly can you attend a leak in Ealing?
Same-day appointments are usually available in Ealing, and next-day almost always. If water is actively escaping, tell us when you book — live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Ealing is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes — trace and access reports documenting the cause, precise origin and affected areas are available for every Ealing detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Ealing do you cover?
All of it — including Ealing, Acton, Hanwell, Southall, Greenford. We cover every London borough, so coverage never depends on which side of a postcode line you live.
My Ealing house still has an old lead or iron rising main under the hall floor. Can you find a leak without lifting the whole floor?
Usually yes. On Edwardian terraces and 1930s semis the rising main and stop-tap often sit under a solid hall floor, so we use acoustic listening, tracing and moisture readings to pinpoint the likely spot before anything is lifted. That narrows excavation to a small area rather than the whole hallway. A fixed leak-detection fee typically falls in the £250 to £450 range, in line with UK trade cost-guide figures.
I live in a converted flat or maisonette in Ealing and damp is spreading, but nobody knows whose pipe it is. Can you help?
We can trace the supply run to work out where the pipe goes and whether the water is coming from your flat or a shared or neighbouring one. Older conversions often have unclear or shared pipework, so establishing the route first helps with both the repair and any freeholder or neighbour discussion. We also check whether the moisture is a leak at all, rather than rising or penetrating damp, before recommending any work.
