Leak Detection Mitcham
Hidden water leaks in Mitcham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Mitcham buildings.
Local knowledge
Mitcham housing, from a leak engineer's side
Mitcham's housing is dominated by interwar terraces and some earlier Edwardian rows, often with original external layouts. Plumbing is typically straightforward but aged, with a high incidence of original cast iron waste stacks and galvanised steel feed pipes. Many properties have single-storey rear additions with basic plumbing, where poor initial work leads to recurrent issues. Access under suspended timber floors is common, allowing for non-invasive leak tracing along the traditional pipe runs.
Engineer's note
A burst galvanised pipe won't respect the clock. Our 24/7 team is geared for Mitcham's interwar terraces, getting to the stop tap and the burst fast to limit water damage.
Covered in Mitcham

What fails here
Common leak problems in Mitcham
01
Cast Iron Stack Corrosion at DPC Level
The original soil stacks in terraced rows often corrode just below ground level or at the damp proof course, causing hidden leaks into the foundation air gap. We use endoscopic inspection to view the pipe condition internally and pinpoint the corroded section for a targeted repair.
02
Galvanised Pipe Blockages and Bursts
Old galvanised steel mains pipes narrow with internal rust, causing pressure build-ups that lead to bursts at weak joints, often under the kitchen sink. A sudden drop in pressure followed by damp patches is a key sign. We locate the burst section and replace the entire feed with modern MDPE pipe.
03
Leaking Drains Under Side Extensions
Many properties have small side-return extensions built over the original clay yard drain runs. Ground movement can fracture these pipes, causing persistent damp and odours. We conduct a drain camera survey from the nearest access point to identify the fracture without digging up the new floor.
04
Faulty Stop Tap Replacement
The primary external stop tap, crucial for isolating a major leak, is often seized or broken in these older terraces. We can replace this critical valve with minimal excavation, ensuring you have immediate control in any future plumbing emergency.
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 Mitcham — FAQs
How quickly can you attend a leak in Mitcham?
Same-day appointments are usually available in Mitcham and across Merton, 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 Mitcham?
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 Mitcham properties?
Yes — Mitcham's housing is dominated by interwar terraces and some earlier Edwardian rows, often with original external layouts. Plumbing is typically straightforward but aged, with a high incidence of original cast iron waste stacks and galvanised steel feed pipes. Many properties have single-storey rear additions with basic plumbing, where poor initial work leads to recurrent issues. Access under suspended timber floors is common, allowing for non-invasive leak tracing along the traditional pipe runs.
Can you provide a report for my insurer?
Every Mitcham detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
