What does Poly B replacement actually cost in Canada?
Repipe quotes can vary by thousands of dollars for the same house, which makes the whole market feel murky. It isn't, once you know the one variable that drives most of the spread.
The 30-second answer
Most full-home Poly B replacements in Canada land between $6,000 and $18,000, with typical detached homes in Alberta and the Okanagan between $8,000 and $15,000 and condos often under $5,000. Access to the pipe, not the size of the house, is the biggest price driver.1

What actually moves the price
- 1Access, above everything. An unfinished basement ceiling means the crew sees the pipe; finished ceilings, tile showers, and vaulted spaces mean cutting and restoring drywall. Two identical floor plans can be thousands apart on this alone.
- 2Bathrooms and fixtures. Each added bathroom or wet fixture adds roughly $800 to $1,500 of pipe, fittings, and labour.3
- 3Storeys. Second and third floors mean longer runs and harder routing.
- 4Material choice. PEX is the standard replacement: it doesn't react to chlorinated water and carries a 50 to 100 year expected service life. Copper is excellent but typically two to four times the material cost.3
What a proper quote includes
A complete repipe is more than pipe. The full scope is drywall access, complete removal of the Poly B, the new PEX system, pressure testing, drywall repair, and paint, done by one crew or coordinated by one contractor. When a quote is dramatically cheaper than the others, the missing money is usually drywall and paint, which you end up buying separately anyway.3
The paperwork matters as much as the pipe: the completion certificate stating full removal, the replacement material, Red Seal certification, pressure test results, and the contractor's licence is what your insurer will ask for. The insurance chapter covers that package in detail.
Timeline
Typical full-home repipes run two to nine days on site depending on size and access, with water off for roughly one to two days in stretches. Most families stay in the home during the work.3
Common questions
Why won't anyone give me a firm price over the phone?
Because the biggest cost driver, access, can't be seen over the phone. A contractor who quotes a firm number without seeing the basement ceiling and bathroom walls is guessing, and the guess protects them, not you. Fixed pricing after a site visit is the standard to look for.
Is the cheapest quote a red flag?
Not automatically, but check what's excluded. Drywall repair, paint, permits, and the insurer documentation package are the common gaps. Compare quotes on identical scope before comparing them on price.
Does replacing Poly B add value to my home?
It removes a negotiating lever more than it adds a premium. Buyers and their inspectors increasingly flag Poly B, insurers may condition coverage on it, and industry reporting suggests homes with original Poly B sell at a discount. A completed repipe with paperwork turns all of that into a non-issue at the negotiating table.4
