Leak Detection Greenwich
Hidden water leaks in Greenwich pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, covering Greenwich, Woolwich, Eltham, Charlton and Blackheath.
No find, no fee
You only pay the detection fee if we locate the leak.
All of Greenwich
Same-day and next-day cover across the whole borough.
Insurer-ready reports
Trace & access documentation loss adjusters accept.
Multi-method survey
Acoustic, thermal, tracer gas and moisture on every visit.
Local knowledge
How Greenwich properties leak
Greenwich housing is dominated by period conversions, post-war estates and new riverside towers. New riverside developments run plastic push-fit pipework in ceiling voids; a single failed O-ring can soak several flats before it surfaces.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest — before we arrive.
Covered in Greenwich
- 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
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.

Common leak problems in Greenwich
01
Concealed Push-Fit Failures in New Builds
Our most frequent call in Greenwich's riverside towers involves leaks from plastic push-fit plumbing systems installed in ceiling voids and service risers. A single degraded O-ring or improperly seated joint can discharge water for extended periods, often migrating laterally to saturate multiple flats before any visible dampness appears. This necessitates acoustic correlation or thermal imaging to pinpoint the source without invasive demolition.
02
Leak Migration in Period Conversions
Properties converted from larger historic houses often have complex, multi-level pipe runs shared between units. A leak in a ground-floor void or within a party wall can manifest as damp in an upper-floor flat, creating liability disputes. We use tracer gas injection and precise moisture mapping to trace the migration path and definitively identify the source flat's responsibility.
03
Aging Infrastructure in Post-War Estates
System-built estates from the mid-20th century frequently have original galvanised steel or early copper pipework now suffering from internal corrosion and pinhole leaks. These often occur within concrete floor screeds or behind prefabricated wall panels. Non-invasive inspection with high-sensitivity acoustic listening devices is critical to locate these failures before significant structural damage occurs.
04
Pressure Stress on Composite Systems
Many borough properties feature hybrid plumbing where modern extensions tie into older systems, or where pipework has been partially replaced. Differential pressure and material incompatibility can cause joint failures. Our engineers conduct systematic pressure testing and use thermal imaging to identify thermal anomalies at transition points, preventing cascading failures.
From the forums
What Greenwich residents say about tracing hidden leaks
Across r/HousingUK, r/DIYUK and MoneySavingExpert, Greenwich threads tend to cluster around two housing types. Owners in the Royal Arsenal Riverside and Woolwich new-builds describe push-fit joints failing inside floor voids and risers, with water tracking down and soaking the flat below before anyone spots a stain. Much of the frustration is not the leak itself but the who-pays dispute between leaseholders, the freeholder and building management, plus the wait for access to shared risers. Owners of Georgian townhouses near the town centre and 1930s Eltham semis more often report slow losses in old concealed pipework. A recurring theme is that people want the source pinpointed and documented before they open a ceiling or file a claim.

How to Choose a Leak Detection Company in London: A Guide to Technology & Precision
Selecting a leak detection company requires evaluating their technology, methodology, and commercial sector expertise. Here's what to prioritise.
Leak detection in Greenwich — FAQs
How quickly can you attend a leak in Greenwich?
Same-day appointments are usually available in Greenwich, and next-day almost always. If water is actively escaping, tell us when you book — live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Greenwich is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes — trace and access reports documenting the cause, precise origin and affected areas are available for every Greenwich detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Greenwich do you cover?
All of it — including Greenwich, Woolwich, Eltham, Charlton, Blackheath. We cover every London borough, so coverage never depends on which side of a postcode line you live.
A leak from the flat above is soaking my Royal Arsenal Riverside flat. Who is responsible?
Responsibility usually depends on where the leak originates and what your lease says, so it often becomes a dispute between the upstairs leaseholder, the freeholder and building management. A neutral leak-detection survey that pinpoints and documents the source helps everyone agree who should act and supports an insurance claim. We provide an insurer-ready report; we do not decide liability.
Can you find a leak in a period Greenwich townhouse or 1930s Eltham semi without damaging finishes?
Yes. In older concealed pipework we use non-invasive methods such as acoustic listening, thermal imaging and moisture readings to narrow the source before anything is opened up. This limits disruption to original plaster, cornicing and floors. You receive a written report showing where the leak is, typically for a fixed fee of £250 to £450 depending on access and property size.
