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 is the borough's most mixed stock: new-build apartment blocks and warehouse conversions along the creek and Deptford High Street sit beside surviving Georgian terraces around Albury Street and later Victorian streets. New builds bring pressurised manifold plumbing, underfloor heating and concealed risers; warehouse conversions carry long horizontal pipe runs across former industrial floors; the Georgian and Victorian houses hold the familiar rear back-addition pipework corner. Leaks hide differently in each: buried manifold joints under new screeded floors, shared horizontal runs above converted flats, and boxed-in back-addition pipes in the period houses, so the surfacing point is often a long way from the failing joint.
Engineer's note
Deptford asks for range: on new builds and warehouse conversions I follow the manifold and the long horizontal runs with thermal imaging and pressure isolation, while on the Georgian and Victorian houses I keep tracing non-invasive to spare the old fabric. In every case I prove the source before access, so the trace and access report is precise enough for the freeholder or insurer.
Covered in Deptford

What fails here
Common leak problems in Deptford
01
Underfloor heating leak in a new-build flat
New-build apartments around Deptford Creek often run underfloor heating from a concealed manifold under screed. A falling pressure with no visible water usually means a circuit or manifold joint is leaking into the slab. We thermal-image the floor to map the warm circuits, then confirm the leak point with tracer gas so only a small section of finished floor is disturbed.
02
Long horizontal run leaking in a warehouse conversion
Warehouse conversions carry water across wide former industrial floors in long horizontal runs above and between flats. A leak mid-run can travel the length of a ceiling before it drips, making the source hard to place. We trace the run acoustically and by pressure isolation to find where the pipe has actually failed rather than where the water shows.
03
Georgian terrace concealed supply damp
The Georgian houses around Albury Street hide original and upgraded supply pipes within thick walls and deep back additions. A slow weep can salt and darken lath-and-plaster a good distance from the actual source, and the historic fabric makes exploratory opening costly. We moisture-map the area and trace the run non-invasively, opening only the small spot where the leak is proven to sit.
04
Shared stack leak between converted flats
Conversions of period and industrial buildings frequently share a single waste stack across several flats. A blockage or failed joint on the stack surfaces in whichever flat sits below the fault, not the one that caused it. We trace the stack and isolate branches to identify the responsible flat and give the managing agent a clear report.
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 is the borough's most mixed stock: new-build apartment blocks and warehouse conversions along the creek and Deptford High Street sit beside surviving Georgian terraces around Albury Street and later Victorian streets. New builds bring pressurised manifold plumbing, underfloor heating and concealed risers; warehouse conversions carry long horizontal pipe runs across former industrial floors; the Georgian and Victorian houses hold the familiar rear back-addition pipework corner. Leaks hide differently in each: buried manifold joints under new screeded floors, shared horizontal runs above converted flats, and boxed-in back-addition pipes in the period houses, so the surfacing point is often a long way from the failing joint.
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.
