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 includes grand Victorian and Edwardian houses, many with original, well-built rear service wings that have been upgraded to luxury kitchens and bathrooms. The plumbing here is often extensive, with long pipe runs from the original core to the wing, and may include underfloor heating in newer additions. The focus is on preserving period features and high-value finishes, making non-invasive leak location a priority to avoid damaging ornate plasterwork and joinery.
Engineer's note
For high-value period properties, we integrate thermal imaging to screen large areas for moisture patterns, followed by tracer gas injection for definitive, pinpoint location with zero structural damage.
Covered in Blackheath

What fails here
Common leak problems in Blackheath
01
Long-Run Pipework Corrosion
Extended copper runs from the original utility basement to the rear wing are common. These long, often poorly accessible runs are susceptible to galvanic corrosion at intermittent support points, leading to pinhole leaks.
02
Underfloor Heating Manifold Leaks
Modern underfloor heating systems installed in back-addition slabs have complex manifolds. Leaks at manifold valves or within the screed are low-volume but constant, leading to slow, widespread slab saturation and inefficient heating.
03
Leaks Beneath Original Floorboards
Pipework feeding the wing often runs beneath original, wide-board timber floors in the main house. Leaks here directly threaten irreplaceable period flooring and require precise location to limit board removal.
04
Void Condensation Misdiagnosed as Leak
Temperature differentials between the main house and a glazed rear extension can cause significant condensation in subfloor voids. This moisture is often mistaken for a plumbing leak, requiring clear differentiation.
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 includes grand Victorian and Edwardian houses, many with original, well-built rear service wings that have been upgraded to luxury kitchens and bathrooms. The plumbing here is often extensive, with long pipe runs from the original core to the wing, and may include underfloor heating in newer additions. The focus is on preserving period features and high-value finishes, making non-invasive leak location a priority to avoid damaging ornate plasterwork and joinery.
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.
