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 mix includes tightly packed early-Victorian workers' cottages and larger Edwardian terraces, many with historic back-additions. These properties often have shallow foundations and high water tables, exacerbating damp in the pipe-concentrated rear extensions. A history of industrial use in parts of the area means some soil conditions are aggressive to metal pipes. The prevalence of basement and cellar conversions in some streets adds another complex layer where leaks can manifest far from their source.
Engineer's note
We specialise in differentiating plumbing leaks from environmental damp in high-risk areas, producing the technical proof that streamlines insurer approval and cost-recovery.
Covered in Deptford

What fails here
Common leak problems in Deptford
01
Aggressive Soil Corrosion
Historical industrial land use can create acidic soil conditions that aggressively corrode buried lead and iron supply pipes where they enter the back-addition. This causes sudden pipe failure. We take soil and pipe samples to provide forensic evidence of external corrosion for complex insurance claims.
02
High Water Table Flooding
A high water table means any leak from a buried pipe or drain in the back-addition can quickly flood a cellar or sub-floor void. Determining if water ingress is from a leak or groundwater is crucial. Our differential pressure tests provide definitive proof of a plumbing leak, not ground water, for the insurer.
03
Basement Leak Misdiagnosis
Leaks from ground-floor back-addition bathrooms can travel down through party walls and appear as damp in a basement conversion. We use tracer gas and endoscopic cameras to prove the leak path, preventing insurer rejection due to suspected 'rising damp'.
04
Historic Drain Collapse
Original brick barrel drains running under back-additions are prone to collapse from root ingress and ground movement, causing waste water back-up. Our CCTV drain surveys provide the clear visual evidence of collapse that insurers mandate before approving excavation and repair.
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 mix includes tightly packed early-Victorian workers' cottages and larger Edwardian terraces, many with historic back-additions. These properties often have shallow foundations and high water tables, exacerbating damp in the pipe-concentrated rear extensions. A history of industrial use in parts of the area means some soil conditions are aggressive to metal pipes. The prevalence of basement and cellar conversions in some streets adds another complex layer where leaks can manifest far from their source.
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.
