Leak Detection for Townhouses
Townhouse complexes combine private plumbing with shared walls and common drainage, so a single leak can affect neighbours and trigger strata involvement.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
In-depth detection guidance for townhouses, tied to every BC city.
Most BC townhouses are wood-frame strata properties built from the 1990s onward, with poly-B or copper supply lines, party walls and shared perimeter drainage. Leaks migrate along shared walls and into adjacent units more readily than in detached homes.
- Party-wall and shared-plumbing leaks between units
- Poly-B and copper supply-line failures
- Crawlspace and perimeter-drain seepage in complexes
- Roof and envelope leaks on multi-unit roofs
- Acoustic and thermal detection along shared walls
- Moisture mapping across adjacent units
- Tracing complex drainage to find the failure point
