Poly-B Repiping Cost in Vancouver for Houses and Condos

Replacing the polybutylene (Poly-B) supply lines in a Vancouver house with PEX typically lands in the low five figures for a detached home, and well under that for a single condo or townhouse unit. The spread is wide because the price is driven by fixture count, how many floors the pipe runs through, how much drywall has to be opened and repaired, and whether the finish work is included in the quote. Below are the typical ranges we see across Metro Vancouver, labelled as such, plus the factors that push a specific house toward the top or the bottom of the range.

Why Poly-B is a Vancouver problem in particular

Polybutylene was installed in a large share of BC homes built or renovated from the late 1970s to the late 1990s. It is the grey (sometimes blue or black) flexible pipe you can usually spot at the water heater, under sinks or in the mechanical room. The pipe itself degrades slowly from chlorine in municipal water, but the usual failure point is the fitting: early acetal (plastic) fittings crack, and crimp rings loosen over decades of thermal cycling.

Much of the Lower Mainland's townhouse and low-rise condo stock dates from exactly that window, which is why the topic keeps coming up in strata depreciation reports and insurance renewals. Several insurers in BC now ask whether a home still has Poly-B, and some will decline a new policy, raise the water-damage deductible, or require replacement within a set period.

Typical repiping cost ranges in Metro Vancouver

Treat these as planning numbers in Canadian dollars, not quotes. Every figure assumes PEX supply lines, a licensed crew, a City of Vancouver or municipal plumbing permit, and pressure testing before walls are closed.

Copper instead of PEX generally adds 35 to 60 percent to the labour and material portion. Painting of the patched areas is the most common item quoted separately, so ask whether a number covers drywall patching only, patching and primer, or a full paint finish.

The factors that move a Vancouver quote

Fixture count and bathroom spread. Every sink, toilet, tub, shower, dishwasher, washer and hose bib is a run that has to be fished through the building. Three bathrooms stacked on top of each other are cheaper to repipe than three bathrooms at opposite ends of a long bungalow.

Floors and access. Single-storey homes with an open crawl space or unfinished basement are the easiest: most horizontal runs happen below the floor and only short vertical drops need wall openings. Finished basements, slab-on-grade construction and three-storey townhouses all add openings and ceiling work.

Wall and ceiling finishes. Standard drywall is quick to open and patch. Lath and plaster in older Vancouver Specials, tile, wood panelling and textured ceilings all slow the work and raise the restoration portion of the price.

Strata rules and scheduling. In a strata, you may need to coordinate water shut-downs with the building, give notice to neighbours, book the elevator and work within noise bylaw hours. Some stratas also have a repiping specification from a past building-wide project. That coordination time shows up in the quote.

Water heater, main shut-off and pressure. A repipe is the natural moment to replace a corroded main shut-off, add a pressure-reducing valve if incoming pressure is high (common in parts of the North Shore and Burnaby), and swap an aging water heater. These are add-ons and should be listed as separate line items.

Permit and inspection. The City of Vancouver requires a plumbing permit for repiping, and the surrounding municipalities have their own permit processes under the BC Plumbing Code. Permit fees are modest compared with the job, but a quote that skips the permit is a warning sign and can create problems at resale or with an insurance claim.

What the work looks like day to day

A typical detached-home repipe runs three to five working days. The first day is protection and layout. Days two and three are the pipe runs, usually one floor at a time so the house keeps water overnight wherever possible. Pressure testing happens before any wall is closed, and the municipal inspection is booked at the rough-in stage. The last day or two are drywall patching, taping and mud.

Condo units move faster, often two to three days, because the runs are short and the building's risers are not part of the job. Expect to be without water for parts of each day, not for the whole project, and ask for a scope that says exactly when.

Poly-B in a strata: who pays for what

In a BC strata, the dividing line is usually the Strata Property Act's distinction between common property and the strata lot. Pipes serving only one unit are often the owner's responsibility, while risers and lines serving more than one unit are typically common property. Bylaws and the registered strata plan can change that split, so the strata's own documents govern. Many stratas choose a building-wide repipe funded from the contingency reserve or a special levy because it is cheaper per unit and avoids a patchwork of half-replaced systems.

If you are buying in a 1980s or 1990s building in Vancouver, read the depreciation report and recent minutes for the word "polybutylene" before you remove subjects.

Spot repair or full repipe?

A single failed fitting can be cut out and replaced with a PEX transition in a couple of hours, which is sometimes the right call for a home about to be gutted anyway. For a house or unit you plan to keep, the usual advice is that the second Poly-B leak is the signal to repipe. By then the fittings have reached the age where failures cluster, and repeated water-damage claims can cost more in premiums and deductibles than the repipe itself.

Frequently asked questions

Is Poly-B pipe banned in BC?

Polybutylene is no longer an approved material for new potable water piping under the BC Plumbing Code, so it cannot be installed in new work. Existing Poly-B does not have to be removed by law. The pressure to replace it comes from insurers, strata councils and buyers, not from a municipal order.

Does homeowner insurance in Vancouver cover Poly-B leaks?

It depends on the policy. Many BC insurers still cover sudden water damage from a burst Poly-B line, but some apply a higher water-damage deductible, exclude Poly-B specifically, or ask for replacement as a condition of renewal. Review the current wording and ask the broker directly, because the answer changes from one insurer to the next.

How long does a Poly-B repipe take in a detached house?

Most two-bathroom detached homes take three to five working days including drywall patching, with water back on at the end of each day in most areas of the house. Larger homes with a basement suite can run a full week. Painting the patched areas, if included, adds a day or two at the end.

Should I choose PEX or copper for the repipe?

PEX is the default choice for repiping a finished Vancouver home because it can be pulled through existing wall cavities with fewer openings, it tolerates minor freezing better, and it costs less installed. Copper is a reasonable choice for exposed runs in mechanical rooms or where a strata specification calls for it, but expect the higher material and labour cost noted above.
