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, so long as the leak is one arising inside your own property in Ealing: attend, fail to locate it, and you are not charged the detection fee. It is not cover against the leak being someone else's. Where the trace ends at a neighbouring property, a communal riser or the mains before your boundary, we have located it and the visit is payable.
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.
The leak is in a loft conversion en-suite above our bedroom. What happens at night?
The good news is that an en-suite added in a loft is usually fed by a short run that can be closed locally, often at a service valve under the basin or behind the cistern, without shutting the whole house. The bad news is the ceiling below it, which takes the water. Close the local valve if you can find it, move whatever is under the wet patch and leave the lights on that circuit off. Pinpointing which fitting failed is quick once nothing is flowing. Check whether the water is warm, since a warm leak points at heating or hot supply and narrows things considerably.
Our stop tap disappeared when the kitchen was extended. What now?
It is almost certainly still there, behind or under whatever was built across it, and that is worth solving before an emergency rather than during one. In the meantime the outside stop tap becomes your isolation point, usually in the front path or at the pavement edge, and it needs a key. Plenty of Ealing houses have had two or three kitchens fitted over the decades, so a buried tap is common rather than unlucky. Knowing the outside one turns is the practical answer. Freeing a stiff outside tap is cheap; replacing a snapped one after it shears off is not.
How is a night visit different from a survey booked for the morning?
A night visit is aimed at stopping the situation. A daytime survey is aimed at answering the question. At night the priorities are isolation, electrical safety and containment, plus whatever can be established without opening anything. A booked survey has daylight, time, the full set of equipment and no pressure to leave the property usable in the next twenty minutes, which is when acoustic, thermal and tracer work does its best job. A lot of calls genuinely want the second, and we will say so rather than sell you the first.
How do we tell a flat-roof problem from a plumbing leak?
Watch the weather and watch the clock. Water that appears during or shortly after rain, stops within a day or two of it drying up, and shows up near the junction between an extension and the original house is behaving like a roof. Water that runs regardless of the weather, continues through the night when nobody is using anything, and is clean and steady is behaving like a pipe. Temperature helps too, since a hot supply or a heating leak is warm to the touch and a roof leak never is. The meter is the decider: shut every tap, watch the dial or the display for an hour, and if it moves you have a supply leak somewhere. That test costs nothing and saves calling out the wrong trade.

ReadHow Leak Detection Works: The Methods, What Each One Reads, and Where Each One Fails
Leak detection is not one technique. It is a sequence: prove there is a leak, work out which system it is on, then use the method that suits the pipe, the floor and the failure. Here is how each method works and what defeats it.
