Leak Detection Woolwich
Hidden water leaks in Woolwich pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Woolwich buildings.
Local knowledge
Woolwich housing, from a leak engineer's side
Woolwich pairs the new-build density of Royal Arsenal Riverside with older ex-council blocks and street after street of Victorian and Edwardian terraces inland. The riverside apartments are built for speed, with plastic push-fit pipework threaded through ceiling voids, risers and behind dry-lined walls, and manifold systems serving several rooms from one point. That is exactly where a single failed O-ring or an under-seated push-fit collar can soak two or three flats before anyone sees a stain. The ex-council stock adds its own issues, with communal risers, boxed-in stacks and aging supply runs. Leaks here move vertically through the building, so the damage often appears well below the fault.
Engineer's note
Woolwich riverside leaks call for moisture mapping across the affected voids and slabs and close coordination with building management, since the source often sits in a flat above the one that reports the damage. We trace to a single joint, agree a fixed fee at booking, work no find no fee, and leave you with an insurer-ready trace and access report.

What fails here
Common leak problems in Woolwich
01
Failed push-fit O-ring soaking flats below
Royal Arsenal Riverside plumbing relies on push-fit joints in concealed voids. When an O-ring perishes or a joint was never fully home, water tracks along the void and drops through a ceiling one or two storeys down. We use thermal and acoustic tracing to find the exact joint without opening every ceiling, and report it for building management.
02
Communal riser leaks in ex-council blocks
Older Woolwich blocks carry shared supply and waste risers behind access panels and boxing. A leak on a communal run can affect several homes and needs careful coordination with the managing agent. We trace the fault to a single point so the right pipe is opened, not a whole stack.
03
Manifold and concealed pipe leaks behind dry lining
New-build flats often feed rooms from a central manifold through pipes run behind plasterboard. A weep at a connection shows as a spreading damp patch with no visible pipe. Moisture mapping and thermal imaging let us follow the run and pinpoint the leak behind the board.
04
Waste and shower-tray leaks in new bathrooms
In the newer apartments, a poorly sealed shower tray or a loose waste connection can let water past the finish and into the void every time the room is used. The tell is a stain that darkens after showering. We confirm whether it is a supply leak or a waste and sealing failure before any tiling comes up.
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 Woolwich — FAQs
How quickly can you attend a leak in Woolwich?
Same-day appointments are usually available in Woolwich 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 Woolwich?
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 Woolwich properties?
Yes — Woolwich pairs the new-build density of Royal Arsenal Riverside with older ex-council blocks and street after street of Victorian and Edwardian terraces inland. The riverside apartments are built for speed, with plastic push-fit pipework threaded through ceiling voids, risers and behind dry-lined walls, and manifold systems serving several rooms from one point.

The ex-council stock adds its own issues, with communal risers, boxed-in stacks and aging supply runs. Leaks here move vertically through the building, so the damage often appears well below the fault.
Can you provide a report for my insurer?
Every Woolwich detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
