Leak Detection Deptford
Hidden water leaks in Deptford pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Deptford buildings.
Local knowledge
Deptford housing, from a leak engineer's side
Deptford's housing includes tightly packed early-Victorian workers' terraces, many with historic, single-story rear 'scullery' additions now serving as modern kitchens and bathrooms. These structures are often of poorer original construction, with low ceilings and pipework crammed into a minimal cavity between the original rear wall and the addition's inner skin. The proximity to the river and high water table exacerbates dampness in this already vulnerable zone.
Engineer's note
Acoustic correlation is highly effective in these dense, small properties to isolate the precise leak point within the saturated cavity, preventing unnecessary masonry removal.
Covered in Deptford
- Hidden leaks under floors and in walls

What fails here
Common leak problems in Deptford
01
Cavity-Wall Saturation
The narrow cavity housing the plumbing in these scullery additions acts as a capillary break, wicking moisture from the ground. Chronic dampness in this cavity accelerates pipe corrosion and conceals active leaks until plaster fails.
02
Ground-Movement Induced Fractures
Shallow foundations on clay soil near the river cause seasonal movement. This stresses rigid pipe runs fixed across the junction between the main house and the back-addition, leading to fractures at elbow joints.
03
Condensate Drainage Misrouted
Boilers and condensate pipes for new combis in back-additions are often poorly routed. Leaks from these acidic drains corrode nearby potable water pipes and are mistaken for a freshwater leak.
04
Historic Brickwork Degradation
Pipe brackets drilled into soft, historic lime mortar loosen over time, allowing waste pipes to sag. This creates negative gradients, leading to standing water and joint failure within the wall.
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 Deptford — FAQs
How quickly can you attend a leak in Deptford?
Same-day appointments are usually available in Deptford and across Lewisham, 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 Deptford?
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 Deptford properties?
Yes — Deptford's housing includes tightly packed early-Victorian workers' terraces, many with historic, single-story rear 'scullery' additions now serving as modern kitchens and bathrooms. These structures are often of poorer original construction, with low ceilings and pipework crammed into a minimal cavity between the original rear wall and the addition's inner skin. The proximity to the river and high water table exacerbates dampness in this already vulnerable zone.
Can you provide a report for my insurer?
Every Deptford detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
