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 is characterised by long rows of late-Victorian terraces with distinctive back-addition 'scullery' extensions. These narrow, single-story additions typically house the kitchen and a ground-floor bathroom, creating a compact wet zone. The original brickwork in these extensions is often of lesser quality and more exposed to damp, making pipe runs within the walls particularly vulnerable. Many properties have undergone piecemeal modernisation, leaving hybrid plumbing systems that are prone to failure at the junctions between old and new.
Engineer's note
Our documented tracing of leaks to the damp scullery environment provides the causal evidence insurers need to approve claims for both the leak and the necessary investigative work.
Covered in Catford
- Hidden leaks under floors and in walls

What fails here
Common leak problems in Catford
01
Scullery Extension Damp
The original, single-brick 'scullery' walls offer little protection from ground moisture, creating a chronically damp environment for pipework. Corrosion of iron brackets and pipe clips leads to pipes sagging and stressing soldered joints. We document the environmental cause to satisfy insurer requirements for gradual damage claims.
02
Hybrid System Junction Failures
Piecemeal upgrades leave old lead or iron waste pipes connected to modern plastic via incompatible junctions in the cramped scullery corner. These junctions frequently fail, causing leaks. Our report details the specific failure point and material incompatibility for the insurer's assessor.
03
Suspended Floor Leak Spread
Leaks from the scullery often drip into the shallow, unventilated space beneath the suspended timber floor, spreading silently. We use trace equipment to map the full extent of moisture migration, evidence needed for insurers to approve floorboard removal and drying.
04
Obstructed External Drain Access
Shared rear access alleys behind terraces often have obstructed manholes for the main waste runs. Clearing blockages to test for leaks requires specialist access. We video-record the process to justify the costs as part of the leak investigation for your claim.
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 is characterised by long rows of late-Victorian terraces with distinctive back-addition 'scullery' extensions. These narrow, single-story additions typically house the kitchen and a ground-floor bathroom, creating a compact wet zone. The original brickwork in these extensions is often of lesser quality and more exposed to damp, making pipe runs within the walls particularly vulnerable. Many properties have undergone piecemeal modernisation, leaving hybrid plumbing systems that are prone to failure at the junctions between old and new.
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.
