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
Corroded lead or iron rising main under the hall
Across Ealing's Edwardian and interwar houses the original lead or iron rising main often enters under a solid front hall floor, with the stop-tap in a cramped recess. Hard London water thins these pipes from within until the joint weeps into the sub-floor, showing as damp skirtings and a creeping meter rather than an obvious leak. We pressure-test the main and trace acoustically to replace only the failed length.
02
Screed-buried heating pipe leaks in period floors
Heating added to the borough's semis and conversions from the 1960s on was frequently chased into floor screed. A pinhole on that buried run bleeds into the slab, dropping boiler pressure daily and warming a patch of floor while nothing surfaces. Owners top up for weeks as the screed saturates. We pressure-test the circuit and trace the pipe thermally, exposing the single failed section rather than the whole floor.
03
Underground supply pipe losing water before the house
Many Ealing homes still run on an old lead or galvanised supply pipe crossing the front garden, path or drive. When it corrodes or an old joint fails, water escapes underground and the metered bill climbs while the surface stays dry. We pressure-test the incoming supply and use tracing and correlation to pinpoint the break, so the repair targets one section instead of digging the whole run. Detection is offered on a no find, no fee basis.
04
Misleading damp stain far from the real leak
In the borough's mansion flats, conversions and maisonettes, water from a concealed pipe travels along slabs and floor voids before it surfaces, so a ceiling stain or damp wall often sits well away from the fault. Opening at the visible damage misses the source and multiplies the mess. We trace live pipework under pressure and map moisture to locate the leak precisely before any access is cut.
What the data says about Ealing
How leaks behave in Ealing, and why
Converted houses and retrofitted pipework
12.7% of the stock here is converted or shared houses, well above the London median of 8.8%, ranking 15th of 331. A house split into flats carries pipework threaded through a building never designed to hold it: waste boxed into an original chimney breast, supply chased through lath and plaster, a bathroom sitting over what used to be a bedroom.
Those retrofits are where slow leaks sit, and the runs are rarely where anyone expects. We trace them rather than assume them, which is the difference between lifting one board and lifting a room.
Long private supply pipes
Ealing is a borough of houses rather than blocks: 21.9% semi-detached, 23.4% terraced and 5.1% detached, with only 34.5% in purpose-built flats, close to the London median of 36.6%. More pipework runs underground and outside the building line here, across front gardens and beneath driveways, so the private supply pipe you are responsible for is simply longer than it is in a mansion block.
That changes the method rather than the price. Acoustic ground microphones and correlation along the buried run do the work a thermal camera does indoors, and pinpointing the spot is what keeps the excavation to a square metre rather than a trench.
Who supplies the water in Ealing
Ealing is split between Thames Water and Affinity Water, so which company to report to depends on your postcode rather than your borough. Worth checking before you call: being passed between two companies is the commonest way a week disappears.
The responsibility line does not move either way. The pipe from the boundary stop tap into the property is yours, and so is the four-week window to repair once you have been notified.

Coverage
Main postcode districts in Ealing
London postcodes were drawn for mail routing, not borough boundaries, so several of these run into neighbouring boroughs and a few edge districts are left off rather than claimed. If yours is not listed, we almost certainly still cover it, say the postcode when you call.
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 and out to the M25, 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. At a fixed £160 an hour across a two to four hour survey, the total comes to £320–£640.
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.
