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 substantial Victorian and Edwardian family homes, many of which have undergone significant rear extensions and loft conversions. The classic side-return kitchen extension is almost universal, burying critical pipework. Larger properties also mean longer pipe runs in ceilings and under suspended floors, where leaks can go unnoticed for longer. The proximity to the river can also mean a higher water table affecting underground drainage.
Engineer's note
A leak under your suspended floor won't fix itself. We deploy moisture meters and borescopes for fast, non-invasive diagnosis, 24 hours a day.
Covered in Putney

What fails here
Common leak problems in Putney
01
Loft Conversion Pipework Stress
Adding a bathroom in a loft conversion places new strain on old rising mains and waste stacks. Poorly supported new pipework can shake and leak where it connects to the original system in ceiling voids, often dripping through light fittings in rooms below.
02
Underfloor Leak in Period Homes
The large ground floors of Putney homes often have suspended timber floors. Leaks from buried side-return joints or from old lead communication pipes run unseen beneath the floorboards, leading to rotten joists and a persistent musty smell that signals urgent investigation.
03
River-Adjacent Drain Surcharge
During heavy rainfall, the combined sewer system near the Thames can surcharge. This pushes wastewater back up through the lowest drains in your property, such as basement shower trays or ground-floor toilets, requiring immediate intervention to prevent internal flooding.
04
Extension Roof Valley Leaks
Complex roof lines where a new rear extension meets the original house create valleys and parapets. Blocked gutters or failed flashings here channel water into the structure, often mimicking an internal plumbing leak as it tracks down inside walls near kitchen or bathroom areas.
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 substantial Victorian and Edwardian family homes, many of which have undergone significant rear extensions and loft conversions. The classic side-return kitchen extension is almost universal, burying critical pipework. Larger properties also mean longer pipe runs in ceilings and under suspended floors, where leaks can go unnoticed for longer. The proximity to the river can also mean a higher water table affecting underground drainage.
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.
