Leak Detection Colliers Wood
Hidden water leaks in Colliers Wood pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Colliers Wood buildings.
Local knowledge
Colliers Wood housing, from a leak engineer's side
Colliers Wood has a high density of mansion flats and conversion properties, alongside smaller terraces. The flat blocks frequently have communal heating systems and vertical plumbing stacks. Smaller terraces often have narrow, shared side passages where external drainage and supply pipes are concentrated, creating access challenges for leak investigation.

What fails here
Common leak problems in Colliers Wood
01
Communal Heating Pipe Leaks in Ducts
Heating pipes serving multiple flats run in vertical ducts. Leaks within these sealed ducts soak insulation and cause damp patches on several floors. Trace & access must identify the exact flat and pipe section responsible.
02
Leaks at Supply Tees in Shared Passageways
In terraces, the main supply often runs down a shared passage, teeing off to each property. These buried tee joints are prone to failure, causing water loss that may be billed to one homeowner but originates from a shared point.
03
Bathroom Waste Leaks in Conversion Flats
Flats converted from larger houses often have bathroom waste pipes routed in creative, sub-optimal ways. Poorly supported plastic pipe can sag and leak at joints, affecting neighbouring units.
04
Faulty Pressure-Reducing Valves
High mains pressure in the area requires pressure-reducing valves. When these fail, the resulting surge can blow fittings in older plumbing systems. We test and document valve performance for the claim.
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.
