Here's the useful thing first: Poly-B is less common in the City of Vancouver than most people assume.
Vancouver's housing skews to two eras that mostly miss the 1978–1997 Poly-B window. Much of it is pre-1960, which means galvanized steel. Much of the rest is post-2000 condo, which means modern PEX — or, in buildings from 1995 to 2007, Kitec.
So before you price a Poly-B repipe, it's worth thirty seconds establishing that you actually have Poly-B.
Send us a photo of the pipe where it comes out of your hot water tank, to 604-865-7979 or [email protected]. We'll tell you free what it is — no visit, no obligation, and if it's modern PEX we'll just say so.

What you've probably got, by neighbourhood
Pre-war and pre-1960 houses — the east side, Kitsilano, Kerrisdale, Dunbar, Shaughnessy, Mount Pleasant, Grandview-Woodland. Almost certainly galvanized steel if it hasn't been repiped: rigid grey metal with threaded joints, rusting closed from the inside. The symptom is water pressure that has been declining for years and discoloured water in the morning. Different material, different failure mode, and it needs replacing for different reasons.
Condos built 1995–2007 — downtown, Coal Harbour, Yaletown, False Creek, the Broadway corridor. If the pipe is orange and blue with brass fittings, that's Kitec, not Poly-B. It fails at the fittings through internal corrosion, and it's currently the biggest repipe driver in Vancouver's tower stock.
Where Poly-B genuinely does turn up in Vancouver: the Champlain Heights townhouse complexes from the 1970s–80s, parts of the River District and Marine Drive corridor, some South Vancouver detached housing from the same window, and scattered 1980s–90s infill and townhouse developments across the city.
If you're in one of those, the odds are real. Elsewhere in Vancouver, check first.
If you do have it
Grey plastic pipe, roughly garden-hose flexible, often stamped PB2110, with grey plastic or copper crimp rings.
It fails through two compounding mechanisms: chlorine degradation makes the pipe progressively brittle from the inside, and the original acetal fittings crack. Neither is visible from outside, and it doesn't usually weep before it splits.
Replacement in Vancouver:
Detached home $8,000–$18,000 · Townhouse $6,000–$14,000 · Condo suite $5,000–$12,000
The insurance question
Many BC insurers now restrict coverage, raise premiums or decline new policies on homes with Poly-B. Practices vary and change, so your broker is the only reliable answer for your policy.
After replacement we provide a written completion report, photographs and the permit record — which is what a broker will ask for.
Townhouse complexes and stratas
Vancouver's Poly-B is concentrated in townhouse complexes, which means it's frequently a strata question rather than an individual owner's. Some complexes run coordinated programmes — cheaper per home and less disruptive than a decade of individual work.
If your depreciation report has flagged it and nobody has acted, we'll attend a council meeting and explain the options without a quote attached.
A City plumbing permit is needed to install, change, or upgrade any part of a plumbing system. Repairing leaks, clearing stoppages in pipes or drains, and repairing or replacing valves or faucets do not need a plumbing permit. All work done under a plumbing permit must be inspected before the permit is finalized. City of Vancouver: Plumbing permit
