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 features a mix of Victorian and Edwardian terraces, 1930s semis, and mid-century ex-local authority housing. A recurring issue is the retrofitting of modern combi boilers and associated pipework into homes with outdated distribution systems. This creates pressure spikes and thermal stresses on old lead-turned-copper connections, often hidden within floor voids and behind original lathe and plaster walls, leading to sudden joint failures.
Engineer's note
In Charlton's older homes with modernised systems, we focus on pinpointing failures at material transitions and within concealed spaces, using ultrasonic and fibre-optic tools to target repairs in complex void and wall scenarios.
Covered in Charlton
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
What fails here
Common leak problems in Charlton
01
Failed Lead-to-Copper Transitions
Original lead communication pipes were often spliced to copper decades ago. These incompatible material joints, now stressed by modern system pressure, fail intermittently. We conduct precise soil probe gas detection at the property boundary to confirm a leak on the communication pipe before excavation.
02
Chased-In Pipework Leaks
Pipes for radiator installations were often chased into solid brick walls and plastered over. Micro-fractures from building movement cause slow leaks into the wall core. Long-range thermal imaging cameras detect subtle temperature differentials in the wall surface, revealing the wet pipe run's path.
03
Leaks Under Suspended Timber Floors
Ground-floor pipework in voids is susceptible to condensation corrosion and joint failure. Access is often restricted. We use a combination of ultrasonic leak detection and fibre-optic inspection cameras fed through air bricks to visually inspect the void without lifting floors.
04
Pressure-Induced Leaks in Old Radiator Valves
Modern high-pressure boiler systems cause gland failures in original radiator valves, leaking along the valve spindle into the floor. Acoustic listening devices isolate the hiss of escaping water at the valve itself, distinguishing it from other system noise.
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 features a mix of Victorian and Edwardian terraces, 1930s semis, and mid-century ex-local authority housing. A recurring issue is the retrofitting of modern combi boilers and associated pipework into homes with outdated distribution systems. This creates pressure spikes and thermal stresses on old lead-turned-copper connections, often hidden within floor voids and behind original lathe and plaster walls, leading to sudden joint failures.
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.
