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 many smaller, tightly-packed Victorian workers' cottages, often with single-storey rear kitchen extensions. These compact spaces cram washing machine, sink, and boiler feed pipes together, creating a high-density leak risk zone. Many properties have also been subject to rapid, budget-conscious renovations, which can mask underlying plumbing issues in these damp-prone corners.
Engineer's note

What fails here
Common leak problems in Deptford
01
Washing Machine Feed Leaks in Kitchens
In cramped back-addition kitchens, the washing machine cold feed and waste are often squeezed into a corner. Constant vibration and high-pressure surges can shake loose connections on old pipework, causing rapid leaks that flow behind appliances and under floorboards.
02
Concealed Leaks from Past Renovations
Quick renovations may have boxed in problematic pipework without fixing it. A leak develops unseen behind plasterboard or kitchen panels, only showing as mould at the panel edges or a soft spot in the floor. This requires urgent investigation before structural rot sets in.
03
Condensate Pipe Leaks from New Boilers
Modern combi boilers are often fitted in these old extensions, with plastic condensate pipes routed outside. If poorly installed or frozen, they can leak internally, dripping inside the wall cavity of the back addition and creating a hidden damp patch.
04
Leaks at the Original House Junction
The point where plumbing from the new back addition ties into the original house stack is a classic failure point. Differential movement between the old and new structures can crack seals, causing leaks that appear in the ground-floor room of the main house. Damp on an internal party wall near the back is a key clue.
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 many smaller, tightly-packed Victorian workers' cottages, often with single-storey rear kitchen extensions. These compact spaces cram washing machine, sink, and boiler feed pipes together, creating a high-density leak risk zone. Many properties have also been subject to rapid, budget-conscious renovations, which can mask underlying plumbing issues in these damp-prone corners.
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.
