Smoke and tracer-gas testing for hidden drain failures.
Drain and waste leaks don't always show up as a dripping pipe — they show up as recurring stains, persistent musty odours, or water damage that doesn't track to a supply line. Our smoke and tracer-gas testing pressurizes the drain system with a harmless visible or chemical indicator that escapes through any failure point and can be located precisely on the surface. We do this for residential drain stacks, commercial waste systems, and below-grade lateral failures throughout Greater Vancouver. The deliverable is a single point of failure, not a list of possible causes.
Leaks Detector is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.
We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.
Yes — the standard tracer (hydrogen / nitrogen blend) is non-toxic, non-flammable, and dissipates quickly.
No. The smoke we use is the same theatrical fog used in stage productions; it cleans up by itself within minutes.
On accessible surfaces, yes. On below-grade lines we can usually place the failure to within 30 cm horizontally.
