Leak Detection Hornsey
Hidden water leaks in Hornsey pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Hornsey buildings.
Local knowledge
Hornsey housing, from a leak engineer's side
Hornsey offers a blend of Edwardian semis and smaller Victorian terraces, with a significant portion now functioning as single-floored flats or small HMOs. These conversions often involve subdividing original layouts, requiring plumbing to be re-routed through new partition walls and under suspended timber floors. The proximity of many properties means leaks can quickly become a party-wall issue. Systems are often a mix of original pipework and modern additions, leading to compatibility issues.
Engineer's note

What fails here
Common leak problems in Hornsey
01
Leaks Under Suspended Timber Floors
Pipes routed beneath floorboards in conversion projects are vulnerable to abrasion and condensation corrosion. Leaks here can soak insulation and joist ends, leading to structural damp. We use floorboard inspection cameras and moisture probes to locate the leak without extensive floor removal, providing insurers with a cost-contained diagnosis and repair scope.
02
Party-Wall Service Duct Leaks
When creating separate flats, plumbing is often run in ducts within newly built party walls. A leak in these enclosed spaces can dampen both sides, blurring liability. Our trace and access identifies which flat's pipework is the source, producing the neutral evidence needed for the respective insurers to settle the claim and apportion costs.
03
Corrosion at Dissimilar Metal Joints
Mixing original iron or lead pipes with modern copper or plastic fittings accelerates galvanic corrosion at the joints, a common issue in incremental upgrades. These joints fail predictably. We identify the specific corroded junction and document the material mismatch, satisfying insurer requirements for a cause-of-loss related to material failure, not just wear and tear.
04
Leaks from Abandoned Pipework
During conversions, old pipe runs are sometimes abandoned in situ rather than properly removed. These forgotten pipes can still hold water or decay, causing leaks that are extremely difficult to trace. We map all live and dead plumbing, identifying the abandoned line as the source, which is crucial evidence for insurers to approve the unusual but necessary remedial work.
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 Hornsey — FAQs
How quickly can you attend a leak in Hornsey?
Same-day appointments are usually available in Hornsey and across Haringey, 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 Hornsey?
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 Hornsey properties?
Yes — Hornsey offers a blend of Edwardian semis and smaller Victorian terraces, with a significant portion now functioning as single-floored flats or small HMOs. These conversions often involve subdividing original layouts, requiring plumbing to be re-routed through new partition walls and under suspended timber floors. The proximity of many properties means leaks can quickly become a party-wall issue. Systems are often a mix of original pipework and modern additions, leading to compatibility issues.
Can you provide a report for my insurer?
Every Hornsey detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
