Leak Detection Cheam
Hidden water leaks in Cheam pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Cheam buildings.
Local knowledge
Cheam housing, from a leak engineer's side
Cheam is characterised by larger 1930s detached and semi-detached houses, often with multiple bathrooms across two floors. The longer pipe runs from the original boiler location to distant bathrooms increase the number of joints at risk. Many properties have original lead-to-copper connections at the mains entry, which can corrode where they meet the scaled copper system.
Engineer's note
We carry equipment to trace leaks along long pipe runs common in these larger homes. Don't wait for multiple damp patches—a single stain indicates an active leak.
Covered in Cheam
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss

What fails here
Common leak problems in Cheam
01
Distant Bathroom Leaks
Long hot-water pipe runs to ground-floor cloakrooms or en-suites in extensions contain numerous joints. A leak mid-run is particularly hard to locate as the water can travel along floor joists before dripping through. Stains may appear far from the actual leak point.
02
Corrosion at Service Entry
Where original lead communication pipes connect to the internal copper system, galvanic corrosion is accelerated by the chalky water. This creates pinhole leaks at the connection, often within the floor void under the hallway or kitchen. The first sign is often damp at the skirting board.
03
Leaking Original Towel Rails
Many Cheam bathrooms retain original heated towel rails connected to the hot-water circuit. Scale buildup inside these rails restricts flow and increases pressure on the aged connections. The lower joints, hidden behind panels or under floors, are common failure points.
04
Failing Bib Taps
Original bib taps in utility areas or garages, fed from the domestic hot-water system, are often forgotten. Their aged washers fail, and scale prevents the tap from fully closing. This causes a constant, slow drip that drains into a floor drain or soaks surrounding timber.
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 Cheam — FAQs
How quickly can you attend a leak in Cheam?
Same-day appointments are usually available in Cheam 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 Cheam?
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 Cheam properties?
Yes — Cheam is characterised by larger 1930s detached and semi-detached houses, often with multiple bathrooms across two floors. The longer pipe runs from the original boiler location to distant bathrooms increase the number of joints at risk. Many properties have original lead-to-copper connections at the mains entry, which can corrode where they meet the scaled copper system.
Can you provide a report for my insurer?
Every Cheam detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
