Leak Detection Putney
Hidden water leaks in Putney pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Putney buildings.
Local knowledge
Putney housing, from a leak engineer's side
Putney is dominated by red-brick Edwardian mansion blocks along the Lower and Upper Richmond Roads and the riverside, sitting alongside Victorian terraces on the streets climbing towards Putney Heath and newer apartment schemes near the bridge and Putney Wharf. The mansion blocks are the defining challenge: communal boosted risers, shared bathroom stacks and original pipework threaded between flats mean a single failed joint can affect several leaseholders at once. The terraces below the Heath follow the borough pattern, with side-return kitchen extensions that bury the rear-wall pipe run. Newer riverside flats add concealed plastic pipework in ceiling voids, so leaks here rarely show where they start.
Engineer's note
With Putney's shared mansion-block risers and stacks, the flat reporting the damp is often not the flat with the leak. We trace the stack across flats before recommending access, which prevents the wrong leaseholder paying to open a ceiling, and the written trace report settles who is responsible. Non-invasive throughout, no find no fee.

What fails here
Common leak problems in Putney
01
Communal stack leaks between mansion-block flats
Putney's Edwardian mansion blocks share bathroom and soil stacks that run vertically through several flats. When an old joint on the stack weeps, the damage typically appears one or two floors down, in a flat with no plumbing fault of its own. Tracing this from the affected flat alone is unreliable. We work the stack from the reported damp upward with thermal and acoustic detection, identify the responsible flat, and supply an insurer-ready report so liability between leaseholders is documented clearly.
02
Boosted riser drips on upper-floor flats
To push cold water to the top of the blocks, Putney's mansion flats use boosted systems that keep the pipework under steady extra pressure. Worn olives and ageing valves on the upper floors give way first, and the resulting drip runs down inside the wall before surfacing lower down. We isolate the affected riser the same day where the managing agent grants access, then pinpoint the exact fitting with thermal imaging so only the relevant section of wall is opened.
03
Side-return joint leaking near Putney Heath terraces
The Victorian terraces on the streets rising towards Putney Heath carry the usual side-return kitchen extensions. The pipe crossing the old rear wall is now sealed under a solid extension floor, and a compression fitting that weeps there can track along the screed and emerge against the party wall. Non-invasive tracing at the buried junction locates the fault precisely, so the reinstatement is confined to a small area rather than the length of the new kitchen.
04
Concealed pipe leaks in Putney Wharf flats
The newer riverside apartments near Putney Bridge run plastic pipework through ceiling and floor voids that were sealed at construction. A push-fit joint that loosens over time drips into the void and spreads before it stains a ceiling below. Opening voids blind is wasteful in these finishes. We moisture-map the affected area and trace the run acoustically to mark the joint, keeping access minimal and the detection fee fixed at the point of booking.
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 Putney — FAQs
How quickly can you attend a leak in Putney?
Same-day appointments are usually available in Putney and across Wandsworth, 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 Putney?
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 Putney properties?
Yes — Putney is dominated by red-brick Edwardian mansion blocks along the Lower and Upper Richmond Roads and the riverside, sitting alongside Victorian terraces on the streets climbing towards Putney Heath and newer apartment schemes near the bridge and Putney Wharf. The mansion blocks are the defining challenge: communal boosted risers, shared bathroom stacks and original pipework threaded between flats mean a single failed joint can affect several leaseholders at once. The terraces below the Heath follow the borough pattern, with side-return kitchen extensions that bury the rear-wall pipe run. Newer riverside flats add concealed plastic pipework in ceiling voids, so leaks here rarely show where they start.
Can you provide a report for my insurer?
Every Putney detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
