Leak Detection Carshalton
Hidden water leaks in Carshalton pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Carshalton buildings.
Local knowledge
Carshalton housing, from a leak engineer's side
Carshalton's mix includes Victorian terraces, 1930s semis, and post-war council-built houses. This creates varied plumbing ages and materials. A common feature is the retrofitting of modern combi boilers onto old, scaled pipework. The higher pressure can blow out weakened joints that were previously holding under low-pressure tank systems.
Engineer's note
A leak after a boiler upgrade is an emergency—the higher pressure will quickly worsen the breach. Call for immediate isolation and repair.
Covered in Carshalton
- Hidden leaks under floors and in walls
- Underground supply pipe leaks

What fails here
Common leak problems in Carshalton
01
Combi Boiler Pressure Spikes
Older scaled pipes weren't designed for mains pressure. When a new combi boiler is installed, the sudden pressure surge can fracture already-weakened joints, especially on the hot-water circuit. Leaks often appear shortly after a boiler upgrade.
02
Leaks Behind Built-In Cupboards
In post-war houses, bathroom pipework was often boxed in or hidden behind built-in storage. Leaks from joints within these concealed spaces go undetected until the cupboard base rots or damp spreads to an adjacent wall. Musty smells are often the first clue.
03
Corroded Galvanised Tanks
Many properties still have original galvanised cold-water storage tanks in the loft. Scale and sediment accelerate corrosion, leading to pinhole leaks. Water then drips through the ceiling below, often mistaken for a pipe leak. The tank itself is the source.
04
Faulty Overflows from Scale
Scale jams the ball valve arm in toilet cisterns or cold-water tanks, causing constant overflow. The water often runs down the outside wall, but can also leak internally at the connection point. Homeowners see high water bills or hear constant refilling.
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 Carshalton — FAQs
How quickly can you attend a leak in Carshalton?
Same-day appointments are usually available in Carshalton and across Sutton, 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 Carshalton?
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 Carshalton properties?
Yes — Carshalton's mix includes Victorian terraces, 1930s semis, and post-war council-built houses. This creates varied plumbing ages and materials. A common feature is the retrofitting of modern combi boilers onto old, scaled pipework. The higher pressure can blow out weakened joints that were previously holding under low-pressure tank systems.
Can you provide a report for my insurer?
Every Carshalton detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
