Leak Detection Chiswick
Hidden water leaks in Chiswick pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Chiswick buildings.
Local knowledge
Chiswick housing, from a leak engineer's side
Chiswick is characterised by its well-maintained Victorian and Georgian terraces, many with rear extensions and modernised interiors. These renovations often involve complex plumbing reroutes and underfloor heating installations, which can introduce new pressure points and potential leak sources. High-quality finishes mean leak detection must be minimally invasive to preserve period features. We tailor our methods to protect ornate cornicing, original floorboards, and decorative plasterwork during investigation.

What fails here
Common leak problems in Chiswick
01
Leaks in Renovated Extensions
Kitchen or bathroom extensions on period homes can have plumbing joints that fail under movement or pressure changes. Leaks often damage expensive finishes. We pinpoint the joint precisely, limiting repair work to a small area and providing a focused report for the insurer.
02
Underfloor Heating Leaks
Retrofitted wet underfloor heating systems in these homes have pipework buried in screed. A leak requires exact location to avoid destroying large sections of flooring. Our thermal imaging and acoustic correlators isolate the problem zone, justifying the trace and access costs to your insurer.
03
Concealed Bathroom Waste Leaks
Original cast-iron waste stacks hidden within walls can corrode, leaking slowly into party walls. This causes gradual, widespread damp. We identify the exact stack section responsible, which is essential for insurers to approve access through the wall for repair.
04
Faulty Pressure-Reducing Valves
High mains pressure can stress older pipework in upgraded homes. Failing pressure-reducing valves cause surges that lead to joint failures. We test system pressure and document valve condition, evidence that supports a claim for subsequent leak damage.
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.
