From industrial Erith to suburban Blackfen: Bexley's housing
Bexley grew quickly once the railways came. Bexleyheath developed along the old London to Dover road, while estates and farmland around Blackfen, Lamorbey and Falconwood were broken up for suburban building, leaving the streets of semis and short terraces that make up much of the borough today. Erith has a longer history as a Thames port that became an industrial town in the late nineteenth century.
In the north, Thamesmead was built from the late 1960s by the Greater London Council on the former Erith Marshes, and its first residents moved in during 1968. Early phases used system-built concrete blocks and town houses, later phases returned to brick, and the new town spans the boundary between Bexley and Greenwich.
Mains renewal and the private supply pipe
Thames Water has been replacing ageing mains in the borough, including cast iron pipes around Bexleyheath and the main along Bexley High Street, and upgrading pipes on Chislehurst Road, Elm Road and Station Road in Sidcup. Check your bill to confirm who supplies your address. That company looks after the pipes in the street, while the pipe from your boundary into the house is the owner's responsibility.
New mains in the road do nothing for an old private pipe. In an interwar semi in Sidcup or Welling, the owner's section may still be lead or early copper, often under a front garden that has since been paved for a car. Where one pipe was laid to serve a pair or row of houses, the owners it feeds share the cost of fixing it.
Thamesmead: raised homes, shared ducts and flood history
The land that became Thamesmead had been flooded in 1953, so the original design put living accommodation at first floor level or above, left much of the ground level for garages and linked buildings with overhead walkways. In homes like these, pipes often pass through ducts and slabs shared with neighbours, and a leak can surface in the flat below or next door rather than in the room where it began.
Close to the river, damp at low level is not always a plumbing fault. Before any wall or floor is opened, the engineer checks whether the supply and heating are holding and maps the moisture. A damp and moisture survey is £250 to £450, and the report says whether the evidence points to a pipe or to water coming from outside.
Typical faults in Bexleyheath, Welling and Sidcup semis
Houses from between the wars have often had their heating renewed more than once, with the newer runs set into a kitchen floor or clipped beneath the boards. A radiator that stays cold at one end, a stain creeping along a skirting and a boiler that loses pressure over a few days are the usual clues.
Rear extensions add another weak point, where new pipework in the slab joins the original circuit. Loft conversions sometimes relocate a cold water tank or route pipes through the eaves, and a slow drip there can mark a bedroom ceiling well away from its true source.
Bathrooms added upstairs in later decades are another source. Pipes to a shower or basin often run inside a stud wall or beneath a boxed-in floor, and a weeping compression joint there can soak plasterboard for a long time before a mark shows below.
Methods and prices for a Bexley leak survey
Heating leaks in solid floors are usually found with thermal imaging at £150 to £250. Supply pipes beneath lawns and block paving are traced acoustically at £150 to £300, and tracer gas at £200 to £350 is used where the pipe is plastic or the sound is too faint to follow. A buried supply pipe survey is £300 to £500, and a combined survey £250 to £500.
For flats where a repair has to be agreed with a housing provider or freeholder, a trace and access survey at £350 to £450 gives a written record of what was found and where. When water is actively coming through a ceiling, emergency detection is from £300 in working hours and £450 out of hours. Phone 020 3912 0200 to book.
Before the visit, note whether the meter moves while nothing is in use, how quickly the boiler pressure falls, and whether any neighbour on a shared pipe has noticed low flow. Those details help the engineer choose where to start.

Leak Detection in Bexley: Common Questions
Who is responsible for the water pipe outside my Bexley home?
The water company named on your bill is responsible for its main in the road and the connection up to your property boundary, so report a leak in the street to them. From the boundary into your home, the supply pipe belongs to the owner. Where one pipe feeds several houses, the owners it serves share responsibility for repairing it.
Can you find a leak in a Thamesmead flat without opening the floor?
The search itself needs no opening. The engineer confirms which system is losing water, then uses thermal imaging, moisture readings and, for quiet plastic pipes, tracer gas to find the point of escape. The position is marked so the repair can be limited to a small area. In a rented home, tell your landlord or housing provider before booking.

My meter keeps moving but I cannot see a wet patch. Where could the water be going?
Under a long or paved front garden, water from a supply pipe leak can drain into the ground and never reach the surface. It can also be lost under a suspended floor, or through a cistern that runs quietly into the pan. We check the fittings indoors first, then follow the supply pipe from the boundary with acoustic equipment or tracer gas.
