Leak Detection Charlton
Hidden water leaks in Charlton pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Charlton buildings.
Local knowledge
Charlton housing, from a leak engineer's side
Charlton is largely Victorian and Edwardian terraces and semis on the slopes between the river and Charlton village, with pockets of later infill and some post-war housing. The older homes carry the usual period mix of lead and early copper supply pipes, iron waste stacks and suspended timber ground floors that have often been boxed in or overlaid. Bathrooms added into former bedrooms and rear-return extensions bring newer plumbing tied into aging runs. Leaks hide behind lath-and-plaster, under floorboards and inside boxed-in stacks, and because these are terraces the water can travel along joists and appear next door or in the room beyond. Damp on chimney breasts and ceilings rarely marks the true source.
Engineer's note
Charlton's terraces let water travel, so the visible damp and the actual leak are usually in different places. We trace non-invasively through period plaster and suspended floors to confirm the source before anything is opened, keeping the work to a single spot. Fixed fee agreed at booking, no find no fee, and an insurer-ready trace and access report.

What fails here
Common leak problems in Charlton
01
Leaks tracking along joists in terraces
In a Victorian terrace, water from a bathroom or a supply pipe can run along the joists and surface several feet away, often near a chimney breast or in the next room. We trace the flow back with thermal and acoustic equipment so the ceiling is opened directly beneath the leak, not under the stain.
02
Aging iron waste stack leaks behind boxing
Original cast-iron soil and waste stacks, often boxed in, can corrode and weep at joints. The damp shows on a wall or ceiling with no visible pipe. We locate the leaking section within the boxing so only that panel is removed and the right length of stack is dealt with.
03
Rear-return and extension roof ingress
Charlton's rear-return extensions and flat-roofed additions let rainwater in at failed junctions and outlets, and the damp often lands near a kitchen or bathroom pipe. Moisture mapping separates roof ingress from a plumbing leak so you chase the right fault.
04
Pinhole leaks in old copper under floorboards
Decades-old copper supply runs under suspended floors can develop pinholes that drip onto joists and, over time, into the ceiling below. The clue is often a musty smell or a soft board. Acoustic tracing finds the leak so a couple of boards are lifted rather than the whole floor.
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 Charlton — FAQs
How quickly can you attend a leak in Charlton?
Same-day appointments are usually available in Charlton and across Greenwich, 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 Charlton?
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 Charlton properties?
Yes — Charlton is largely Victorian and Edwardian terraces and semis on the slopes between the river and Charlton village, with pockets of later infill and some post-war housing. The older homes carry the usual period mix of lead and early copper supply pipes, iron waste stacks and suspended timber ground floors that have often been boxed in or overlaid.

Damp on chimney breasts and ceilings rarely marks the true source.
Can you provide a report for my insurer?
Every Charlton detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
