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.
Common leak problems in Ealing
Corroding Rising Mains
In Ealing's Edwardian terraces, original lead or iron rising mains are still common. Corrosion often concentrates at the stop-tap joint located under the front hall floorboards. This can cause a gradual leak that soaks the subfloor or a sudden failure. Our engineers are equipped to trace and replace these ageing sections.
Stop-Tap Failures
A seized or leaking stop-tap is a frequent emergency call. In older properties, decades of mineral buildup and corrosion render the original valve inoperable. This prevents you from isolating the water supply during a leak. We can replace the stop-tap, often requiring careful access under floorboards.
Leaks Under Floorboards
The suspended timber floors in period properties hide pipework. Leaks from corroded joints or pinholed pipes can go unnoticed until damp patches appear on ceilings below or floorboards warp. We use non-invasive moisture meters and thermal imaging to locate the exact source without unnecessary damage.
1930s Semi-Detached Pipework
Homes from the 1930s expansion often have original iron or galvanised steel pipes. These are now beyond their lifespan, prone to internal rust buildup that restricts flow and leads to pinholed leaks, especially at elbows and joints. We assess the entire system's condition during any leak investigation.

How to Choose a Leak Detection Company in London: Speed is Everything
Choosing a leak detection company in London comes down to one critical factor: response speed. Here’s how to ensure you get immediate, 24/7 action.
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.
