Leak Detection Erith
Hidden water leaks in Erith pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Erith buildings.
Local knowledge
Erith housing, from a leak engineer's side
Erith presents a mix of late Victorian/Edwardian conversions, interwar semis, and considerable post-war council-built housing. This creates a diversity of plumbing systems, from original two-pipe systems to modern combi-boiler installations. Proximity to the river can influence ground conditions. Many properties have undergone piecemeal plumbing upgrades, resulting in hybrid systems.
Engineer's note
In Erith's hybrid systems, we correlate thermal imaging data with acoustic findings to identify failing interfaces between different pipe materials.
Covered in Erith
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
What fails here
Common leak problems in Erith
01
Hybrid System Incompatibility Leaks
Piecemeal upgrades result in connections between old lead, copper, and plastic pipes. Different expansion rates and jointing methods cause failures at these interfaces, which are often hidden in floor voids. Leaks are often seasonal, worsening with temperature changes.
02
Original Two-Pipe System Concealed Drips
Surviving two-pipe systems (separate hot and cold feeds) have double the pipework in the void. A pinhole leak in an old gravity-fed hot pipe can drip slowly onto insulation, evaporating before causing visible damp. Prolonged moisture mapping reveals the pattern.
03
Ground Conditions Masking Subfloor Leaks
Damp ground conditions can mean the subfloor is perpetually moist. A fresh pipe leak adds to this baseline, making it hard to detect via moisture meters alone. Thermal imaging identifies the anomalous temperature signature of fresh, pressurised water ingress.
04
Waste Pipe Subsidence Fractures
Ground movement can fracture rigid clay or cast-iron waste runs beneath the floor. This causes continuous but variable leakage, depending on wastewater discharge. The leak smell is pronounced, but the fracture can be distant from the inspection chamber.
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 Erith — FAQs
How quickly can you attend a leak in Erith?
Same-day appointments are usually available in Erith and across Bexley, 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 Erith?
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 Erith properties?
Yes — Erith presents a mix of late Victorian/Edwardian conversions, interwar semis, and considerable post-war council-built housing. This creates a diversity of plumbing systems, from original two-pipe systems to modern combi-boiler installations. Proximity to the river can influence ground conditions. Many properties have undergone piecemeal plumbing upgrades, resulting in hybrid systems.
Can you provide a report for my insurer?
Every Erith detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
