How Much Does a Poly-B Repipe Cost in BC?
If you are reading this, you probably have a reason. Maybe a contractor handed you a quote that made you blink. Maybe a letter from your insurer mentioned Poly-B and a deadline. Maybe a home inspection flagged grey plastic pipe under the sink and now you are trying to figure out what you are actually looking at.
The honest answer is that Poly-B repipe pricing in BC covers a wide range, and the number on your quote depends on your specific home. But "it depends" is not a useful answer when you are trying to budget. So here is the real breakdown: what the work typically costs, what moves the price up or down, and how to read a quote so you know whether it is fair.
What a Poly-B Repipe Typically Costs in the Lower Mainland
Across Metro Vancouver and the Lower Mainland, a full Poly-B repipe for a typical single-family home usually lands somewhere between $10,000 and $20,000. The full spread looks roughly like this:
Smaller homes and condos (1 to 2 bathrooms): around $6,000 to $10,000
Average family homes (around 3 bathrooms): around $12,000 to $18,000
Larger or custom homes with long pipe runs: $20,000 and up
These are general market ranges for BC, not a quote for your house. BC labour rates and property values push repipe costs higher here than in much of the rest of Canada, so do not be alarmed if your number is at the upper end of what you have read about online. The only way to know your real price is an on-site assessment. At Ark, that comes back to you as a written quote, and the price we quote is the price you pay.
What Drives the Price Up or Down
Two homes the same square footage can come in thousands of dollars apart. Here is what creates that gap.
Access is the single biggest factor. Replacing pipe in an open, unfinished basement or a crawlspace you can move through is straightforward. Rerouting pipe through finished ceilings, tiled walls, or a tight attic is slow, careful work, and it costs more. If your mechanical room and pipe runs are easy to reach, your quote goes down.
Number of bathrooms and fixtures. Every sink, toilet, shower, tub, and hose bib is a connection point. More fixtures means more pipe, more fittings, and more labour hours.
Home size and layout. A sprawling two-storey with long runs between floors takes more material and time than a compact single-level. Split-level and heavily renovated homes with layered plumbing from different eras tend to surprise people, in the wrong direction.
Slab vs. basement. Homes with pipe run in or under a concrete slab are more involved than homes where pipe runs through accessible joist space. Slab situations sometimes require rerouting through walls and ceilings instead, which changes the scope.
Drywall and finishing. Getting to the pipe almost always means opening walls and ceilings. How much, and how nicely it has to be put back, is often one of the largest single line items on a repipe.
PEX vs. Copper: What Ark Recommends
For almost every residential repipe, Ark installs PEX, and we back it with a 25-year warranty.
PEX is flexible cross-linked tubing that has become the standard for modern residential plumbing in Canada. It resists corrosion, tolerates freezing better than rigid pipe, needs fewer fittings (which means fewer potential leak points), and meets BC plumbing code. Because it installs faster and the material costs less, a PEX repipe typically runs noticeably cheaper than copper, often in the range of 20 to 40 percent less.
Copper is still a fine material, and some homeowners want it for resale reasons. But it costs significantly more in both material and labour, and for the vast majority of homes it does not buy you better day-to-day performance. We are happy to quote copper if you want it. We just will not push you toward it when PEX is the better value for your situation.
If you want the deeper version of why we trust PEX to outlast Poly-B by decades, we wrote about pipe lifespans here: How Long Do Poly-B Pipes Last?
What Is Included vs. What Costs Extra
This is where cheap quotes and complete quotes separate. A proper Poly-B repipe quote should account for the whole job, not just the pipe.
Typically included in a complete repipe:
Full removal and replacement of Poly-B supply lines with PEX
All necessary fittings and connections
Pressure testing the new system
Permits and inspection (required for code compliance and to keep your insurance valid)
Reconnection of your existing fixtures
Often quoted as separate line items or excluded entirely:
Drywall repair, taping, texture matching, and paint. Some companies handle this in-house, some patch to a "ready to paint" state and leave the finishing to you, and some do not touch it at all. Ask exactly what "restoration" means in your quote.
New fixtures, faucets, or valves if you want them upgraded while the walls are open
Bringing other out-of-code plumbing up to standard once it is exposed
None of these are hidden traps when they are spelled out up front. They become a problem only when a quote stays quiet about them and the costs land on you later.
Does the Insurance Savings Offset the Cost Over Time?
Sometimes, and it is worth checking, but be careful about treating it as the whole justification.
Many BC insurers now treat active Poly-B as a liability. Depending on your provider, you may face higher premiums, reduced coverage, a non-renewal notice, or a requirement to replace it within a set window. Removing the Poly-B can stabilize your coverage and, with some insurers, lower your premium. Over many years those savings add up, but they rarely match the full cost of the repipe on their own.
The stronger financial case is usually two other things. First, a single Poly-B failure can cause water damage that easily costs more than the entire repipe, and you may be on the hook for some of it. Second, resale: homes with known Poly-B tend to sell for a few percent less than comparable repiped homes, and they shrink your buyer pool because many buyers see Poly-B as an immediate post-purchase expense. A repipe removes that discount and that hesitation.
Run the math for your own situation. We are happy to talk it through honestly, including the cases where waiting is a reasonable choice.
Red Flags in a Cheap Quote
A low number is only a good deal if it is for the same scope of work. Here is what to watch for when one quote comes in well under the others.
No mention of permits or inspection. Skipping the permit shaves cost now and can void your insurance and create problems at resale later. This is not a corner worth cutting.
Drywall repair left vague or excluded without saying so. If finishing is silently off the table, the "cheap" quote may cost you more once you hire someone to close the walls.
No written, itemized quote. A verbal estimate or a single lump-sum number with no breakdown gives you nothing to hold them to.
No licensing or insurance details. Every repipe should be done by a plumber certified through Technical Safety BC, working for a company that is bonded and insured. Ask, and confirm.
Pressure to decide today. Reputable companies give you a written quote and let you think.
A partial repipe sold as a full one. Replacing the easy-to-reach pipe and leaving Poly-B buried in the walls is not a repipe. Make sure the quote covers the whole system.
The goal is not to find the lowest number. It is to find the quote where you understand exactly what you are getting, so you can compare like with like.
