Leak Detection Catford
Hidden water leaks in Catford pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Catford buildings.
Local knowledge
Catford housing, from a leak engineer's side
Catford mixes Victorian and Edwardian terraces around Culverley Green and Corbett Estate with a heavy layer of interwar semis and pockets of ex-council housing off the South Circular. The Corbett terraces are well built but carry the usual rear back-addition where kitchen and bathroom pipework is stacked in one corner. Interwar semis add solid floors and buried heating runs from later refits, while ex-council blocks bring shared risers and communal supplies. Leaks hide in the boarded back-addition corner, under screeded interwar kitchens, and in the communal pipework of converted or council-built flats, so damp frequently surfaces a floor or a room away from where the pipe has actually failed.
Engineer's note
In Catford I take particular care to tell a buried heating leak in an interwar solid floor from rising damp, because the two look alike at skirting level. Thermal imaging and tracer gas locate the pipe fault to a small square, and on the ex-council blocks I trace communal risers before opening anything so responsibility is clear on the trace and access report.

What fails here
Common leak problems in Catford
01
Buried heating leak under an interwar solid floor
Catford's interwar semis often had heating pipes set into solid or screeded floors during later refits. A gradual pressure loss with no puddle usually means a buried pipe or manifold joint is weeping into the slab. We thermal-image the floor to trace the warm loss and confirm with tracer gas, pinpointing a small area rather than breaking up the whole kitchen or hall.
02
Corbett terrace back-addition damp
In the Corbett Estate terraces the rear addition stacks the kitchen over the bathroom, so a failed waste seal or supply joint upstairs wets the corner below and darkens the party wall. Nothing shows at the source because it is boxed in. We moisture-map the corner and trace acoustically to fix the exact joint before opening the boarding.
03
Communal riser leak in ex-council flats
Ex-council blocks around Catford run shared risers and communal supplies, so a leak on a riser can surface in a flat that is not the source. We trace the communal pipework non-invasively and isolate branches to establish whether the fault sits with the freeholder's communal system or an individual flat, which matters for who repairs and who claims.
04
Rear extension flat-roof outlet leaking
Many Catford kitchens sit under later flat-roof extensions whose outlets and upstands fail with age, letting rainwater into the wall in a way that mimics a plumbing leak. We use moisture profiling and dye testing to separate the roof drainage defect from any internal pipe, so the report names the roof rather than sending you chasing pipework.
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 Catford — FAQs
How quickly can you attend a leak in Catford?
Same-day appointments are usually available in Catford 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 Catford?
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 Catford properties?
Yes — Catford mixes Victorian and Edwardian terraces around Culverley Green and Corbett Estate with a heavy layer of interwar semis and pockets of ex-council housing off the South Circular. The Corbett terraces are well built but carry the usual rear back-addition where kitchen and bathroom pipework is stacked in one corner. Interwar semis add solid floors and buried heating runs from later refits, while ex-council blocks bring shared risers and communal supplies. Leaks hide in the boarded back-addition corner, under screeded interwar kitchens, and in the communal pipework of converted or council-built flats, so damp frequently surfaces a floor or a room away from where the pipe has actually failed.
Can you provide a report for my insurer?
Every Catford detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
