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 characterised by sprawling inter-war and post-war suburban housing, mostly houses and low-rise flats, with some newer infill developments. Properties often have original galvanised steel pipework, later extended with copper, and many have loft conversions adding pressure to old systems. Leaks frequently occur where different pipe materials join.
Engineer's note
A leak hidden in a cavity or under a floor won't fix itself. We respond around the clock to find it before the damage spreads.
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
Loft conversion pipework leaks
Adding a bathroom in a loft conversion strains existing plumbing. New pipe runs are often boxed in or hidden under insulation. A leak at a solder joint or valve in this enclosed space can drip down through multiple floors before becoming obvious.
02
Galvanised steel to copper joint failures
Homes with original galvanised steel pipes often have sections replaced with copper. The dielectric connection between these dissimilar metals corrodes over time, leading to sudden failure and significant leaks, often inside wall cavities.
03
Garden tap and outside pipe leaks
Many houses have long runs of pipe feeding garden taps or outbuildings. These pipes, often poorly insulated, can freeze and split in winter. The leak flows back along the pipe run, entering the house structure at the point it passes through the wall.
04
Leaks under suspended timber floors
Ground floors in many houses are suspended timber. Leaks from original underfloor pipework or from new extensions can pool in the sub-floor void, leading to rot and damp before any water is seen in the living space.
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 characterised by sprawling inter-war and post-war suburban housing, mostly houses and low-rise flats, with some newer infill developments. Properties often have original galvanised steel pipework, later extended with copper, and many have loft conversions adding pressure to old systems. Leaks frequently occur where different pipe materials join.
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.
