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
Blackheath is known for its large Victorian and Edwardian villas, many subdivided into spacious flats, and prestigious modern mansions. Plumbing systems are often complex, with original cast-iron waste stacks, later additions, and high-spec contemporary installations in newer homes. Leaks in these substantial properties can cause major damage before detection.
Engineer's note
In large, high-value properties, every minute a leak continues increases the repair cost. Our engineers are on standby for rapid response.
Covered in Blackheath
- Hidden leaks under floors and in walls

What fails here
Common leak problems in Blackheath
01
Cast iron waste stack failures
Grand period properties have large, original cast-iron soil and waste stacks. Internal corrosion can cause leaks that seep slowly through brickwork for weeks, presenting as damp on multiple floors. Sudden catastrophic failure is also possible.
02
Leaks in multi-bathroom manifold systems
Larger modern homes and converted flats often use a central manifold system with individual runs to each bathroom. A leak at the manifold or in one of the many concealed plastic supply lines can pressurise wall cavities and floor voids across a wide area.
03
Leaking parapet gutters and valley gutters
The complex rooflines of large villas feature internal gutters. When these block or their linings fail, water is channeled inside the roof structure. It can then travel down inside walls, mimicking a plumbing leak from an upper-floor bathroom.
04
Under-slab supply pipe leaks
Many properties have the incoming water supply pipe running under a solid ground floor slab. If this pipe fractures, water migrates through the sub-base, causing rising damp and floor damage far from the actual leak point, complicating detection.
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?
Yes — Blackheath is known for its large Victorian and Edwardian villas, many subdivided into spacious flats, and prestigious modern mansions. Plumbing systems are often complex, with original cast-iron waste stacks, later additions, and high-spec contemporary installations in newer homes. Leaks in these substantial properties can cause major damage before detection.
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.
