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 has significant post-war housing alongside older pockets, including many ex-local authority homes built with concrete ground floors. Where suspended floors exist, they are often in interwar semis near the town centre. Properties may have older galvanised steel pipework, and the proximity to the river can influence ground conditions. Later upgrades mean a mix of plumbing systems, sometimes poorly integrated.

What fails here
Common leak problems in Erith
01
Galvanised Pipe Failure
Many post-war homes used galvanised steel for both supply and waste. This pipe corrodes internally, eventually sealing itself shut or bursting. A leak often appears at a threaded joint first, but the corrosion can be widespread under floors.
02
Ground Moisture vs. Leak Confusion
Damp patches on solid concrete floors are common, but could be rising damp or a leak from embedded under-floor pipework. Our engineers quickly distinguish between the two using moisture meters and thermal imaging to avoid unnecessary excavation.
03
Leaks in Vented Loft Spaces
Cold, draughty loft spaces in these homes can lead to frozen header tank pipes or condensate lines in winter. A thaw can then cause a leak that flows down inside a cavity wall, emerging far from the original source.
04
DIY Plumbing in Updated Homes
Homes modernised over decades can have a patchwork of copper, plastic, and old steel pipes joined together under floors. These incompatible connections are weak points that frequently spring leaks under pressure.
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 has significant post-war housing alongside older pockets, including many ex-local authority homes built with concrete ground floors. Where suspended floors exist, they are often in interwar semis near the town centre. Properties may have older galvanised steel pipework, and the proximity to the river can influence ground conditions. Later upgrades mean a mix of plumbing systems, sometimes poorly integrated.
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.
