Leak Detection Blackheath
Hidden water leaks in Blackheath pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Blackheath buildings.
Local knowledge
Blackheath housing, from a leak engineer's side
On the Greenwich side of Blackheath, around the heath and Blackheath Standard, the housing is handsome Georgian and Victorian: detached and semi-detached villas, tall townhouses and solid family homes, many with original features carefully kept. These properties carry lengthy runs of period pipework, lead and early copper supply, iron waste, threaded behind ornate plaster, under wide suspended floors and inside deep wall voids. Basements and cellars are common and hide supply runs and stopcocks. Because owners here rightly protect cornicing, panelling and original floors, a leak that surfaces on a decorative ceiling demands a genuinely non-destructive trace. Water often travels far from its source through the generous voids of these larger houses.
Engineer's note
Blackheath work is about protecting original fabric while still finding the leak. We trace non-invasively through period plaster, cellars and wide floor voids, confirm the exact source before a single board or panel is lifted, and keep disruption to a minimum. Fixed fee agreed at booking, no find no fee, and an insurer-ready trace and access report.
Covered in Blackheath
- Hidden leaks under floors and in walls
- Underground supply pipe leaks

What fails here
Common leak problems in Blackheath
01
Leaks staining ornate period ceilings
In these villas a small leak above a decorated ceiling can spread across cornicing and plaster before it is noticed. Cutting exploratory holes risks irreplaceable detail. We trace the source with thermal and acoustic equipment from above or alongside, so the leak is confirmed and only the minimum is opened.
02
Basement and cellar supply leaks
Many Blackheath homes have cellars carrying old supply pipes and the main stopcock. A weep down here can raise humidity, damage stored contents and feed damp into the floor above. We locate the leaking joint or run precisely rather than replacing sound pipework on suspicion.
03
Long buried runs in large family homes
The generous footprint of these houses means supply and heating pipes travel a long way under floors and through walls. A leak can surface rooms away from the fault. Moisture mapping and tracing follow the run to its true source before any original floor is lifted.
04
Roof and valley ingress on tall townhouses
Tall Georgian and Victorian townhouses have complex roofs, valleys and parapets where water can enter and run down internal walls, mimicking a plumbing leak. We use moisture mapping to distinguish rainwater ingress from a pressurised leak so the right trade addresses the right problem.
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 Blackheath — FAQs
How quickly can you attend a leak in Blackheath?
Same-day appointments are usually available in Blackheath 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 Blackheath?
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 Blackheath properties?

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