Leak Detection Blackheath
Hidden water leaks in Blackheath pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Blackheath buildings.
Local knowledge
Blackheath housing, from a leak engineer's side
Blackheath is known for its grand Georgian and Victorian houses, many of which have undergone significant rear extensions to create modern kitchen-diners and en-suites. While high-spec, these renovations still concentrate new wet rooms in the traditional back-addition zone, often over old cellar spaces. The use of underfloor heating and complex appliance systems in these extensions adds potential leak sources. The premium nature of properties demands leak detection that causes minimal disruption to high-end finishes, aligning with insurers' expectations for careful claims handling.

What fails here
Common leak problems in Blackheath
01
Leaks Under High-Spec Finishes
Leaks from pipes serving luxury back-addition wet rooms can damage expensive stone tiles, underfloor heating, and fitted cabinetry. Our non-invasive acoustic and infrared detection precisely locates the leak before any flooring is lifted, controlling investigative costs for the insurer.
02
Underfloor Heating Manifold Leaks
Manifolds for underfloor heating systems are often installed in back-addition utility cupboards. Pressurised system leaks at manifold joints are common and can go undetected under screed. We use thermal imaging to identify anomalous heat patterns that pinpoint the leak without unnecessary excavation.
03
Void Leaks into Cellars
Many properties have vaulted cellars or basements beneath the back-addition. Leaks from new pipework in the extension floor can drip into this pristine storage space. We use tracer gas testing to confirm the vapour trail from leak to void, providing clear evidence for the claim.
04
Integrated Appliance Supply Failures
High-end kitchens in extensions feature multiple plumbed-in appliances (coffee machines, ice makers) fed from a single supply line in that congested corner. Leaks from plastic push-fit connectors behind integrated units are frequent. We isolate and test each branch line to identify the specific failing component for the claim report.
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 Blackheath — FAQs
How quickly can you attend a leak in Blackheath?
Same-day appointments are usually available in Blackheath 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 Blackheath?
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 Blackheath properties?
Yes — Blackheath is known for its grand Georgian and Victorian houses, many of which have undergone significant rear extensions to create modern kitchen-diners and en-suites. While high-spec, these renovations still concentrate new wet rooms in the traditional back-addition zone, often over old cellar spaces. The use of underfloor heating and complex appliance systems in these extensions adds potential leak sources. The premium nature of properties demands leak detection that causes minimal disruption to high-end finishes, aligning with insurers' expectations for careful claims handling.
Can you provide a report for my insurer?
Every Blackheath detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
