WHAT VANCOUVER HOMEOWNERS FACE
Many Vancouver homes, townhouses, and condos built or renovated between the late 1970s and mid-1990s still rely on Poly B (polybutylene) water lines, which are now 30 to 45 years old. Chlorine in the city water supply slowly breaks down the plastic from the inside, causing hidden leaks behind walls and ceilings at fittings and crimp rings. In multi-unit properties, a single pipe leak can quickly cause damage to neighboring units below or next door.
We replace failing Poly B with durable PEX or copper across Vancouver neighborhoods, including Kitsilano, Fairview Slopes, False Creek South, Mount Pleasant, the West End, Kerrisdale, Marpole, Oakridge, Champlain Heights, Killarney, Fraserview, Renfrew-Collingwood, Sunset, Hastings-Sunrise, and Dunbar. We specialize in 1980s and 1990s low-rise condos, townhouses, and renovated detached houses, working directly with strata councils and property managers on building-wide repipes. All work includes municipal permits with the City of Vancouver, coordinated drywall patching, and our 2-year labour warranty, double the industry standard.
Common reasons homeowners act now:
Poly B does not need to be actively leaking to justify an assessment.
Hidden failure
risk
30- to 45-year-old pipes brittle from chlorine cause unannounced leaks.
Insurance
concerns
Insurers charge higher rates, limit coverage, or refuse Poly B properties.
Strata & neighbor impact
Multi-unit leaks can damage adjoining suites and trigger high deductibles.
Home sales & inspection
Home inspectors flag Poly B, impacting property sales.

HOW TO IDENTIFY POLY B
Homeowners and strata owners can usually spot Poly B as flexible grey (sometimes blue or black) plastic piping near the hot water tank, under sinks, behind washing machines, or at the main water shut-off. It is typically joined with copper or plastic crimp rings at the fittings.
Coverage may be limited or cost more.
Insurance concerns
Crimped connections are common failure points.
Aging fittings
Future plans
Replacement can help before a sale or renovation.
Purposeful openings. Respect for your home is part of the job.
