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 offers a blend of Victorian and Edwardian terraces, 1930s semi-detached houses, and modern low-rise apartment complexes. A common feature is the prevalence of suspended timber floors in older properties and shared drainage pathways in the newer flats. Leaks from ground-floor bathrooms or kitchens can quickly drop into the subfloor void and travel laterally, affecting multiple rooms before detection.
Engineer's note
In Charlton, we focus on distinguishing between internal plumbing failures and external water ingress, a critical determination that dictates which section of a household insurance policy applies.
Covered in Charlton
- Hidden leaks under floors and in walls
- Underground supply pipe leaks

What fails here
Common leak problems in Charlton
01
Subfloor Void Leak Migration
Homes with suspended timber floors have a continuous void. A leak from a ground-floor appliance or pipe drops down and flows along the top of the subfloor, emerging at the perimeter walls far from the source. We use moisture mapping to plot the migration path back to the origin, a vital step for an insurer to understand the full extent of damage.
02
Terrace Shared Drainage Blockages
Rows of terraced houses often share a single drainage run to the sewer. A blockage in the shared section can cause back-up and flooding in the lowest property. We use CCTV drainage surveys to identify the location and cause of the blockage, determining liability between neighbours for insurance purposes.
03
Flat Complex Balcony Leaks
Low-rise apartment complexes often have balconies above living spaces. Failed balcony waterproofing or drainage is frequently misdiagnosed as an internal plumbing leak. Our water testing procedures isolate the source, ensuring the claim is correctly categorised under building insurance or contents cover.
04
1930s Home Lead Main Joint Leaks
Many 1930s semis have lead mains with soldered joints that fail with ground movement. The leak follows the pipe trench, potentially undermining foundations. We trace the leak along the pipe run with specialised equipment, documenting the exact joint failure for the insurer's structural repair assessment.
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.
