Local Knowledge - Hounslow
Serving residents near Chiswick House, Kew Bridge Steam Museum, and Osterley Park.
From Chiswick's riverside to the interwar streets of Feltham
Hounslow stretches a long way west from Chiswick. In the east, Chiswick has Georgian houses by the river at Strand on the Green and Chiswick Mall, Victorian and Edwardian streets, and a small part of Bedford Park, the garden suburb begun in 1875. Brentford mixes older terraces with new flats beside the canal and river, including the developments around Brentford Lock.
Further west the borough is mainly suburban. The Great West Road opened in 1925 and set off a decade of building, and by the early 1930s new housing was spreading across Osterley, Heston and Isleworth where there had been fields and orchards. Feltham and Hanworth also have a great many semi-detached and terraced houses from the 1930s building boom. Much of Hounslow's housing is therefore close to a century old, and most of it has been replumbed at least once.
Interwar semis: where the pipework hides
A 1930s semi in Heston or Hanworth usually started with a suspended timber ground floor and a small kitchen. Most have since gained a rear extension on a concrete slab, a converted garage or a loft room, and the heating was extended each time. The joins between old copper and newer pipe, often buried in the extension floor, are a common place for a leak to begin.
Outside, the supply pipe runs from the boundary under what was a front garden and in many streets is now a paved drive. Houses of this age may still have lead or old iron on the supply side, and a leak there can drain away into the ground without leaving a wet patch. Weak flow at the kitchen tap, or a meter that keeps moving with everything turned off, is often the first clue.
Thames Water, supply pipes and the rivers through Hounslow
Hounslow is supplied by Thames Water, whose Kempton Park treatment works lies partly within the borough. Thames Water looks after the main and the pipe up to the outside stop valve. The supply pipe from that valve into your home is yours, and if it is shared with neighbours, so is the cost of repairing it.
Several watercourses cross the borough. The River Crane and the Duke of Northumberland's River pass through Isleworth before reaching the tidal Thames, and the River Brent meets the Thames at Brentford. Homes close to them, and along the Chiswick riverside, can suffer damp from high groundwater or flooding that is easily mistaken for a leak. Testing the meter and heating pressure first shows whether your plumbing is really losing water.
Choosing a method for a Hounslow home
For supply pipes under lawns and drives, acoustic detection from £150 listens for escaping water along the route. Plastic or deep pipes, which carry sound poorly, are found with tracer gas from £200. Leaks on the buried supply between the boundary and the house are priced as an underground or mains survey, at £300 to £500.
Heating leaks in extension slabs and under floorboards are traced with thermal imaging from £150. Newer flats in Brentford with underfloor heating are covered by under-floor surveys at £300 to £700, and a combined survey with more than one method is £250 to £500.
Each visit ends with a written report marking the leak, so the repair can usually be limited to a few lifted blocks or a small patch of floor. Call 020 3912 0200 to book.
Simple checks before booking in Hounslow
Start with the stop valves. The outside one is usually under a small cover near the front boundary, and the inside one is often under the kitchen sink or where the pipe enters the house. If you have a meter, read it, leave every tap, toilet and appliance unused for an hour, and read it again. Any movement means water is escaping after the meter.
For the heating, note the boiler pressure each morning while the system is cold, and look at the pressure relief pipe on the outside wall. In a Chiswick or Brentford flat, let the neighbour below know early if you suspect a leak, because a slow drip under a floor often reaches their ceiling first. Any plans from past extensions are worth having to hand, since they can show where pipes were rerouted.

Leak Detection in Hounslow: Common Questions
Is Hounslow supplied by Thames Water?
Yes, Thames Water supplies the borough, and its name should be on your water bill. It is responsible for the main and the pipe up to the outside stop valve, so leaks in the road or pavement should be reported to it. The supply pipe from the stop valve into your home is the owner's responsibility, and shared supply pipes are shared between the owners they serve.
Do you cover Chiswick, Brentford, Isleworth, Heston and Feltham?
Yes. We cover the whole London Borough of Hounslow, including Chiswick, Brentford, Isleworth, Osterley, Heston, Cranford, Hounslow town, Hounslow West, Lampton, Hanworth, Feltham, Bedfont and Hatton. The same equipment and published prices apply, whether the property is a riverside flat, a period house or a 1930s semi.
My 1930s Heston semi has low water pressure. Could it be a leak?
It could. Check that the stop tap is fully open, then take a meter reading, use no water for an hour and read it again. If the meter has moved, water is escaping on your side. We trace the supply pipe from the boundary with acoustic equipment or tracer gas and mark the leak, so only a small section of drive or garden needs opening.
Can you tell a leak from river damp in an Isleworth house?
Yes, in most cases. A plumbing leak shows up as lost water on the meter or falling heating pressure, while damp from groundwater or flooding does not. We run those tests first, then map the moisture to see its pattern. The written report sets out what was found, which helps when deciding between a plumber and a damp or drainage specialist.
