Leak Detection Holborn
Hidden water leaks in Holborn pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Holborn buildings.
Local knowledge
Holborn housing, from a leak engineer's side
Holborn presents a mix of converted commercial buildings, modern apartment blocks, and some remaining historic townhouses, often used as professional offices. Plumbing systems are frequently under high demand from commercial use or high-occupancy residential blocks. There is a prevalence of pumped drainage systems and internal soil stacks. Leak detection often occurs out-of-hours to minimise business disruption, requiring thorough, immediate documentation for fast-track insurance processing.

What fails here
Common leak problems in Holborn
01
Leaks in Commercial Conversions
Buildings converted from offices to flats often have complex, repurposed plumbing. Leaks can occur in redundant pipework or at new connections. We map the active systems to isolate the leak, providing a clear system diagram for insurers that distinguishes legacy pipework from current supply lines.
02
High-Rise Internal Stack Leaks
Modern apartment blocks rely on internal soil and vent stacks. A leak in a stack joint can affect multiple floors. We conduct a coloured dye test from the suspected source flat to visually confirm the leak path. This definitive test provides incontrovertible evidence for claim approval and cost recovery from the responsible leaseholder.
03
Pumped Drainage System Failures
Basement and lower-ground-floor units often rely on pumped drainage systems. Pump failure or pipe blockage causes back-up and flooding. We test the pump and survey the pressure pipe to identify the fault. The report determines if it's a mechanical failure (content of policy) or a blockage (often maintenance).
04
Leaks from Rooftop Plant Areas
Buildings with rooftop plant rooms for HVAC or communal hot water have supply lines prone to freezing or corrosion. Leaks here can cascade down service ducts. We trace the water through risers to confirm the rooftop origin. This places the repair under the building's commercial block policy, not individual residential policies.
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.
