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 cottage-style properties. These homes often have original layout plumbing, with later single-storey extensions adding a kitchen or bathroom. External pipework, including older lead supply lines and outdoor taps, is common. The property mix means leaks frequently occur in accessible but ageing systems.
Engineer's note
Our clear documentation of pipe materials and failure points, especially for lead pipes, gives Mitcham homeowners the evidence needed for insurers to cover full system upgrades, not just patch repairs.

What fails here
Common leak problems in Mitcham
01
Lead Supply Pipe Corrosion
Original lead communication pipes from the mains to the property boundary are prevalent. Corrosion and joint failure here cause supply issues and garden flooding. We trace and expose the pipe, providing material evidence for a full replacement claim.
02
Leaking Outdoor Tap Connections
Many terraces have an outdoor tap on a rear wall. The internal connection often corrodes or the pipe freezes in winter, causing leaks inside the cavity wall or under the kitchen floor.
03
Bathroom Waste Pipe Sagging
First-floor bathroom waste pipes in extensions sometimes lack proper support over time. The sag creates a trap that leads to slow drainage and eventual leakage at joints, damaging ceilings below.
04
Faulty Stop Tap in Front Path
The main stop tap for many terraces is located under the front path slab. Ingress of dirt and corrosion can prevent a full shut-off, complicating emergency repairs. We document its condition for insurer records.
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.
