Victorian streets and interwar cottage estates in Lewisham
Lewisham's housing falls into a few clear groups. Brockley, Ladywell, Forest Hill and Sydenham are largely Victorian, and the Brockley conservation area was built mostly in the 1870s and 1880s, with Italianate stucco and Gothic terracotta detailing. Between Catford and Hither Green, the Corbett Estate added around 3,000 terraced houses between 1897 and 1913 on former farmland bought by Archibald Cameron Corbett.
In the south, the London County Council built the Downham estate between 1924 and 1930, with 7,000 homes on land between Catford and Bromley, and the Bellingham estate close by, laid out on garden city lines with cottages around a central green. Deptford and New Cross add post-war estates and newer blocks, and Lewisham town centre has gained many new flats in recent years.
Corbett Estate terraces and their plumbing
The Corbett houses look alike from the street, but more than a century of new kitchens, bathrooms and loft rooms means no two are plumbed the same way now. Most have suspended timber ground floors over a void, and the back rooms often sit on a later concrete slab. Water from a heating leak under the boards can spread through the void and soften joists long before anything shows in the room.
The supply pipes are often as old as the houses. Where the original lead pipe was never replaced, a joint can fail under the front garden or the tiled path to the door. Lewisham is supplied by Thames Water, which is responsible for the pipe up to the outside stop valve. The section from there into the house belongs to the owner, and a supply shared between houses is a shared responsibility.
Downham and Bellingham: cottage estate houses
Houses on the Downham and Bellingham estates are mostly brick cottages and semis. Some are now privately owned and have been refitted by successive owners, while others are rented from a social landlord. Typical problems include heating pipes laid into a solid kitchen floor during a refit, pipework boxed in behind a bath panel, and stop taps that have seized and will not shut off the supply.
If you rent, report a suspected leak to your landlord. If you own, a quick check shows where to start. Note the meter reading, use no water for an hour and look again, then watch the boiler pressure over a few mornings. A moving meter points to the supply, and a falling pressure gauge points to the heating.
River flooding and damp along the Ravensbourne
The Ravensbourne runs through Catford, Ladywell and Lewisham, where the Quaggy joins it. Flood alleviation schemes have reduced the risk, and at Ladywell Fields the river was reshaped to improve flood control, but the Environment Agency still keeps flood warning areas for the Ravensbourne from Bellingham to Catford and at Lewisham, including Ladywell.
Close to the river, damp in a ground floor or cellar may come from groundwater or surface water rather than a pipe. Before any floor is lifted, we test the supply and heating for loss and map the moisture. A damp and moisture survey is £250 to £450, and a combined leak survey is £250 to £500, each with a written report you can pass to an insurer or landlord.
Methods and prices for a Lewisham survey
Thermal imaging from £150 is the usual method for heating leaks under boards and in slabs. Acoustic detection from £150 suits supply pipes under the front gardens of Hither Green and Catford. Tracer gas from £200 finds quieter plastic pipes, including those in newer flats around the town centre, and under-floor surveys for underfloor heating are £300 to £700.
In Brockley and Ladywell, where plenty of Victorian houses have been split into flats, a trace and access survey at £350 to £450 is often the most useful choice. It covers the search and a written record of the leak position, which helps when the repair involves a neighbour, a freeholder or an insurance claim.
If water is 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 Lewisham: Common Questions
Do you cover Catford, Hither Green, Ladywell and Brockley?
Yes. We cover the whole London Borough of Lewisham, including Deptford, New Cross, Brockley, Crofton Park, Ladywell, Lewisham, Lee, Hither Green, Catford, Forest Hill, Sydenham, Bellingham, Downham and Grove Park. The methods and published prices are the same in every part of the borough.
Our Corbett Estate house keeps losing heating pressure. What should we check?
First look at the pressure relief pipe where it leaves the outside wall. If it is dry, the water is probably escaping inside, often from pipes under the ground floor boards or in the rear slab. Thermal imaging with the heating on shows the pipe routes and any warm spread from a leak, and the engineer marks the spot for repair.
Is a damp cellar near the Ravensbourne always groundwater?
No. Groundwater and river flooding are possible near the Ravensbourne, but a leaking pipe can produce the same signs. We check whether the supply or heating is losing water before drawing any conclusion. If both hold steady, the damp is probably coming from outside, and the report will say so. If not, we trace the leak and mark it.
Who fixes the supply pipe outside my Lewisham home?
Thames Water is responsible for the pipe up to the outside stop valve, which is usually at the boundary. From there into your home, the supply pipe is the owner's to repair. If it serves more than one house, the owners share the responsibility. Our report shows where the leak is, which makes it clear which side of the valve it sits on.
