Queen of the Suburbs: Ealing's period houses
Ealing grew into a middle-class suburb in the Victorian and Edwardian years, much of it with semi-detached houses, and in 1902 the borough surveyor Charles Jones called it the Queen of the Suburbs. Brentham Garden Suburb near Pitshanger, mostly built between 1901 and 1915, was the first garden suburb in London built on co-partnership principles, and it has been a conservation area since 1969.
Between the wars came the mock Tudor houses of the Hanger Hill Garden Estate and the 1930s flats of Ealing Village, now Grade II listed. Beyond Ealing itself, the borough takes in Acton, Hanwell, Southall, Greenford, Northolt and Perivale, each with its own mix of terraces, semis and flats. Because Ealing Village is listed, works affecting its historic fabric can need listed building consent, so knowing exactly where a leak is before anything is opened matters there.
Two water companies supply Ealing
Affinity Water supplies Greenford, Northolt, Perivale and much of Southall, while Thames Water supplies Acton, Ealing, Hanwell and the rest of the borough. Your bill confirms which applies. Both work on the same principle: the company owns the main and the connection up to your boundary, and the supply pipe from there into the house is the owner's.
In an Edwardian house the supply pipe may still be lead if it has never been replaced, and under a deep front garden or a tiled path it can fail well away from the building. Some older streets also have one supply feeding two or more homes, which makes a repair a joint matter between the owners it serves. A written report showing the leak position gives every owner the same evidence to work from.
Suspended floors, extensions and period finishes
Edwardian houses in Ealing and Brentham were built with timber floors over a void, and many have since had a kitchen extension added on a concrete slab. Heating leaks under the boards can soak the void unseen, while a leak in the slab may only show as a boiler that keeps losing pressure. Owners with original parquet, tiled halls or decorative plaster usually want the leak found before anything is lifted.
In Brentham, Hanger Hill and other conservation areas, the survey works from the surface. Thermal imaging, from £150, reads heat through plaster and boards. Acoustic detection, from £150, listens for pressurised water under tiled paths, and tracer gas, from £200, finds plastic or deep pipes. A trace and access survey at £350 to £450 records the leak position in writing for your insurer.
Flats and conversions: pipes that serve more than one home
Blocks such as Ealing Village and houses converted into flats share one problem: pipework that serves more than one household. A leak in a bathroom above can travel along a joist or a riser and appear in the flat below, so the survey starts by checking both homes for water loss before following the moisture to its source.
Newer blocks usually have plastic pipes in screed and often underfloor heating, where a leak makes little noise. Under-floor surveys are £300 to £700, and a combined survey using several methods is £250 to £500. The written report states which pipe and which flat the leak was traced to, which also helps when the repair has to be agreed with a freeholder.
Checks worth making in an Ealing home
Before booking, read the meter, use no water for an hour, then read it again. Note the boiler pressure on cold mornings, and look at the pressure relief pipe and radiator valves for drips or crusting. With a long front garden, walk the route from the boundary to the door and look for grass that stays greener or ground that stays soft in dry spells, since either can mark a supply leak.
If you rent, tell your landlord as soon as you suspect a leak. If you live in a flat, ask the neighbour above for access on the day. For water coming through a ceiling now, emergency detection is from £300 in working hours and £450 out of hours. Call 020 3912 0200.

Leak Detection in Ealing: Common Questions
Is my Ealing home on Affinity Water or Thames Water?
Affinity Water supplies Greenford, Northolt, Perivale and much of Southall, and Thames Water supplies the rest of the borough, including Acton, Ealing and Hanwell. Streets near the dividing line can go either way, so check your bill. With both companies, the owner is responsible for the supply pipe between the property boundary and the house.
Do you cover Acton, Hanwell, Southall and Greenford?
Yes. We cover the whole London Borough of Ealing, including Ealing Broadway, West Ealing, South Ealing, Pitshanger, Brentham, Hanger Hill, Acton, East Acton, Hanwell, Southall, Norwood Green, Greenford, Perivale and Northolt. The same equipment and published prices apply across the borough.
Can you trace a leak in a Brentham house without damaging original features?
The search is carried out from the surface using thermal imaging, acoustic listening and, where needed, tracer gas. The survey ends with a marked leak position, so any opening for the repair can be kept to one small area. Brentham is a conservation area, so check with Ealing Council if the repair could affect the character of the house.
Our Edwardian house keeps losing boiler pressure. What is the likely cause?
If the pressure relief pipe outside is dry, the water is usually escaping inside the house, often from heating pipes under the ground floor boards or set into an extension slab, or from a weeping radiator valve. Thermal imaging with the heating on shows the pipe routes and any warm spread, and the engineer marks the leak so the plumber opens only that spot.
