Leak Detection Eltham
Hidden water leaks in Eltham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Eltham buildings.
Local knowledge
Eltham housing, from a leak engineer's side
Eltham is 1930s suburban London: bay-fronted semis and short terraces on quiet avenues, with the Arts and Crafts cottages of the Progress Estate standing apart in their own style. These houses commonly have solid ground floors with heating pipework buried in or under the screed, plus original supply runs that have been part-modernised over the years. Later rear extensions and refitted kitchens and bathrooms add newer joints tied into old pipework, often under tiled solid floors. Leaks hide under those slabs and behind the render, showing only as a warm patch, an unexplained damp corner, or a boiler that will not hold pressure. On the Progress Estate the protected exteriors make non-invasive tracing especially important.
Engineer's note
In Eltham most calls come down to a buried heating or supply leak under a solid floor. We map the slab with thermal imaging to find the warm anomaly, pinpoint the fault to a small footprint, and on the Progress Estate keep tracing entirely non-destructive. Fixed fee agreed at booking, no find no fee, insurer-ready report provided.
Covered in Eltham
- 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 Eltham
01
Buried heating leaks under solid floors
Many Eltham semis run central heating pipes in or beneath a solid floor slab. A pinhole leak shows as a warm strip across the floor, a damp edge at the skirting, or steadily falling boiler pressure. We trace the buried circuit with thermal imaging and pinpoint the leak, so only the small area over the fault is ever lifted.
02
Damp in bay window and solid floor junctions
The projecting bays on these 1930s houses create awkward junctions where solid floor meets external wall. Water from a leaking supply pipe or from outside can collect here and be mistaken for rising damp. Moisture mapping tells us whether the source is plumbing or ingress before anything is opened up.
03
Leaks under refitted kitchens and bathrooms
Where a newer kitchen or bathroom has been plumbed into original pipework under a tiled solid floor, a weeping connection can spread damp into adjoining rooms. Non-invasive tracing locates the failed joint so a single area of tiling is lifted rather than a whole floor.
04
Concealed supply leaks on the Progress Estate
The Progress Estate's protected cottages need a careful, non-destructive approach. Aging supply runs behind original finishes can leak without any surface clue beyond a faint stain or a rising bill. Acoustic tracing lets us follow the pipe and confirm the leak while keeping the historic fabric intact.
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 Eltham — FAQs
How quickly can you attend a leak in Eltham?
Same-day appointments are usually available in Eltham and across Greenwich, 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 Eltham?
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 Eltham properties?
Yes — Eltham is 1930s suburban London: bay-fronted semis and short terraces on quiet avenues, with the Arts and Crafts cottages of the Progress Estate standing apart in their own style.

Can you provide a report for my insurer?
Every Eltham detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
