Leak Detection West Norwood
Hidden water leaks in West Norwood pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know West Norwood buildings.
Local knowledge
West Norwood housing, from a leak engineer's side
West Norwood is largely Victorian and Edwardian terraces and semis climbing the hills between Norwood Road and Tulse Hill, with converted flats in the bigger houses and pockets of post-war and later infill housing. Many terraces have been split into upper and lower flats sharing the original supply and waste, and the sloping streets mean pipe runs cross changes in level. Older houses retain lengths of lead and iron pipe. Leaks hide because the gradient carries water downhill inside walls and floors, and because back-additions and rear extensions bury feeds under solid floors where an escape has no visible outlet until it reaches a skirting.
Engineer's note
West Norwood combines a slope and a lot of original lead and iron pipe, so an escape can weep unseen and then travel downhill to show in a lower room. We pressure test the old runs to confirm the leak is real, moisture map to follow the water back uphill, and separate a buried solid-floor escape from rising damp before any lifting.

What fails here
Common leak problems in West Norwood
01
Ageing lead and iron pipe joints failing
Many older West Norwood houses still run lengths of original lead or galvanised iron supply that corrode and weep at joints. The escape is slow and hidden inside a wall or under a floor, spreading damp long before it drips. In converted houses that pipe may serve more than one flat. We pressure test the suspect run to confirm a genuine escape and locate the failing joint, then set out the access needed to reach only that section.
02
Downhill leak tracking on sloping streets
West Norwood's streets climb steeply, so a leak on an upslope or upper-floor pipe runs downhill inside the structure and surfaces in a lower room or the flat below. The visible damp sits well away from the fault. We moisture map the full length of the affected wall and floor and pressure test in sections to work back uphill to the source, opening up at the joint rather than at the point the water reached.
03
Shared supply between upper and lower flats
Terraces split into upper and lower flats commonly share one supply and waste run. When it fails the lower flat takes the damp while the upper flat owns the pipe, so the leak and the bill land on different doors. We isolate and pressure test each flat's branch to identify the responsible length and provide a clear trace and access report for both leaseholders and their insurers.
04
Solid-floor rear-extension escapes read as damp
Rear kitchen and bathroom extensions in West Norwood often bury supply and waste in a solid screed floor with no route to show a leak until it emerges at a skirting or wall junction. Owners assume rising damp and treat the wrong problem. We map moisture across the floor and wall and use tracer gas to pinpoint the buried pipe, confirming a leak against environmental damp before any of the floor is lifted.
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.
Leak detection in West Norwood — FAQs
How quickly can you attend a leak in West Norwood?
Same-day appointments are usually available in West Norwood and across Lambeth, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in West Norwood?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know West Norwood properties?
Yes — West Norwood is largely Victorian and Edwardian terraces and semis climbing the hills between Norwood Road and Tulse Hill, with converted flats in the bigger houses and pockets of post-war and later infill housing. Many terraces have been split into upper and lower flats sharing the original supply and waste, and the sloping streets mean pipe runs cross changes in level. Older houses retain lengths of lead and iron pipe. Leaks hide because the gradient carries water downhill inside walls and floors, and because back-additions and rear extensions bury feeds under solid floors where an escape has no visible outlet until it reaches a skirting.
Can you provide a report for my insurer?
Every West Norwood detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
