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's housing stock is primarily inter-war and post-war semi-detached and detached homes, plus some low-rise estates. Properties typically have traditional pipe layouts, but many have undergone multiple DIY extensions and loft conversions, creating complex, multi-stage modifications to the original copper plumbing. Leaks often occur at these poorly executed junctions or within the inaccessible spaces of later additions, requiring smart tracing to avoid chasing leaks through multiple finished rooms.
Engineer's note
For Eltham's modified period homes, our diagnostics excel at tracing leaks through successive renovations, using thermal imaging and tracer gas to isolate failures in later additions without unnecessary disruption to original structures.
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
Leaks in Loft Conversion Plumbing
Cold water tanks removed and pipework re-routed for loft conversions often leave poorly supported pipes and compression joints in cold roof spaces. These joints fail under thermal cycling. Thermal imaging from below pinpoints the cold spot of an evaporating leak in the ceiling before staining appears.
02
Ground Heave Impact on Incoming Mains
Clay soil subsidence or heave can stress the underground communication pipe entering the property, causing fractures at the entry point or under ground-floor slabs. We use tracer gas injected into the mains pipe to detect escapes at the foundation level without excavation.
03
Leaks Beneath Conservatory Bases
Many extensions like conservatories are built over existing outdoor tap runs or drain lines. Fractures cause damp under the base, migrating into the main house. Moisture mapping establishes the flow direction back to the source pipe under the addition.
04
Corrosion in Original Copper Runs
Early thin-wall copper pipes from the mid-20th century, often run in solid floors, are now prone to pinhole leaks from internal corrosion. High-frequency acoustic listening devices are calibrated to detect the specific sonic signature of a high-pressure pinhole leak through a screed.
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's housing stock is primarily inter-war and post-war semi-detached and detached homes, plus some low-rise estates. Properties typically have traditional pipe layouts, but many have undergone multiple DIY extensions and loft conversions, creating complex, multi-stage modifications to the original copper plumbing. Leaks often occur at these poorly executed junctions or within the inaccessible spaces of later additions, requiring smart tracing to avoid chasing leaks through multiple finished rooms.
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.
