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 is primarily inter-war and post-war semi-detached and terraced homes, alongside some later infill developments. Properties often have original cast iron waste systems and extended plumbing from loft conversions or side-return extensions. These modifications can create complex routes where leaks travel far from their source, appearing in unexpected areas like ground-floor kitchens from a first-floor bathroom fault.
Engineer's note
For Eltham's older homes, our detailed reports distinguish between gradual wear and tear (which may affect coverage) and sudden escape of water, providing the clarity insurers need to process claims swiftly.
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
Cast Iron Waste Pipe Fractures
Original cast iron soil stacks and waste pipes are prone to hairline cracks, especially at junctions. These leaks seep slowly into wall cavities, causing extensive rot before a stain appears. We use endoscopic cameras to visually confirm the fracture inside the pipe, providing definitive proof for an insurer's major works claim.
02
Loft Conversion Pipework Freezes
Many homes have loft conversions with plumbing routed in uninsulated roof spaces. Insufficiently lagged pipes freeze and split, leaking into the ceiling void between the conversion and original house. Our thermal imaging identifies the exact split and the freeze pattern, supporting a claim for escape of water due to frost damage.
03
Side-Return Extension Joint Failures
Kitchen extensions often involve extending the waste run. Poorly made solvent-weld joints on plastic waste pipes fail over time, leaking under the new slab. We use acoustic listening devices and tracer gas to locate the failure without destructive digging, minimising claim costs for reinstatement.
04
Lead Communication Pipe Corrosion
Many properties still have the original lead communication pipe from the mains. Pinhole leaks develop where the lead passes under foundations, saturating the subfloor. We trace the leak to the specific section of lead pipe, evidence required by insurers to approve a full mains replacement claim.
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 is primarily inter-war and post-war semi-detached and terraced homes, alongside some later infill developments. Properties often have original cast iron waste systems and extended plumbing from loft conversions or side-return extensions. These modifications can create complex routes where leaks travel far from their source, appearing in unexpected areas like ground-floor kitchens from a first-floor bathroom fault.
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.
