Search for this and the numbers come back wildly inconsistent. That is the honest starting point, so this page begins by putting the published figures next to each other with attribution rather than adding one more unsourced range to the pile.
No figure below originates here. Each one is what a named source published, with the date it was published.
What is actually published
| Source | Published range | Stated basis |
|---|---|---|
| ER Plumbing and Heating, May 2026 | $8,000 to $15,000, with most jobs $10,000 to $13,000 | Standard Calgary single-family home |
| Pro Star Plumbing, 2026 | $8,000 to $12,000 | Full repipe, average Calgary home |
| RE/MAX Calgary Homes blog | $5,000 to $15,000 | Calgary replacement generally |
| Urban Piping, regional pricing | Around $10,000 to $18,000 | Standard 2,000 square foot home, varying with materials and complexity |
| Reported condo and unit figures | $6,000 to $12,000 | Unit repiping, varying with accessibility and unit size |
The lowest published floor and the highest published ceiling differ by $13,000 on what is nominally the same job. Sources are listed at the bottom of this page.
Why the published numbers disagree
Four reasons, and none of them is that one contractor is cheap and another is expensive.
- Different houses. A bungalow with an unfinished basement and one bathroom, and a two-storey with a developed basement and three and a half bathrooms, are not the same job. Most published ranges do not say which one they priced.
- Different scope. Some numbers include drywall board and tape. Almost none include paint. A few are plumbing only, with restoration left to the homeowner.
- Different dates. A range published three years ago is a different range today, and many pages are quietly recycled.
- Different purposes. A low anchor gets a phone to ring. A high anchor makes a mid-range quote look reasonable. Numbers published by companies selling the work are marketing figures as well as estimates.
What actually moves the number
| Driver | Direction | Note |
|---|---|---|
| Fixture group count | Largest single driver | Bathrooms, kitchen, laundry, hose bibs. Cost tracks connections more closely than square footage |
| Finished basement | Large increase | Access and restoration both go up, often by thousands |
| Storeys | Increase | Vertical runs mean more openings in finished walls |
| Ceiling and wall finish | Increase | Textured or stippled ceilings, wallpaper and specialty finishes are hard to patch invisibly |
| Restoration scope | Large swing | Board and tape, versus sanded, primed and painted, versus nothing at all |
| Occupied during work | Increase | Staging, protection and daily cleanup |
| Condo or townhouse | Varies | Board approval, shared walls, and building schedules |
| Season | Minor | Trade availability rather than material cost |
What a quote has to itemise before it can be compared
Two quotes are only comparable if both answer all of the following in writing. If one is a single number on one line, it is not a quote, it is a hope.
- Pipe material, fitting system and manufacturer
- Number of fixtures being reconnected, listed individually
- Whether permits and inspection are included
- Restoration level, stated exactly: patch, board and tape, or finished and painted
- Whether paint matching is included and to what standard
- Whether outdoor hose bibs, irrigation and any secondary suite are in scope
- Whether the water heater, softener and any treatment equipment are reconnected
- How the old pipe is handled, removed or abandoned in place
- Expected number of working days and whether the house is habitable throughout
- What happens to the price if something unexpected is found behind a wall
- Cleanup and debris removal
- A fixed written total rather than an hourly estimate
The frame to hold onto is a fixed written price against a written scope. Comparing on the total alone rewards the quote that left the most out.
Is drywall repair included
Usually only partly, and this is the single most common surprise. Most repipe quotes that mention drywall mean board and tape: the hole is closed and the seams are taped. Sanding, priming, texture matching and paint are frequently a separate trade and a separate invoice.
On a whole-home repipe in a finished Calgary house, the restoration can be a meaningful share of the total. It is worth asking for the drywall and paint scope as its own line, and worth knowing whether the crew doing it is a drywall trade or a plumbing crew patching holes.

Common questions
How much does it cost to replace Poly B in Calgary?
Published Calgary ranges run from about $5,000 at the low end to about $18,000 at the high end, clustering around $10,000 to $13,000 for a standard single-family home. Every one of those figures comes from a company selling the work, and none of them describes a specific house.
Is there a Poly B replacement cost calculator for Calgary?
Not a reliable one. The two largest drivers, fixture group count and restoration scope, are not things a calculator can see, so a calculator output is an anchor rather than an estimate.
What is the cost to replace Poly B pipes in a bungalow versus a two-storey?
A two-storey costs more for the same floor area, because vertical runs mean more openings in finished walls. A bungalow with an unfinished basement is the cheapest common case in Calgary.
Is PEX repiping cost different from other materials?
PEX is the standard replacement and the baseline for published pricing. A full copper repipe is materially more expensive and is now uncommon for a whole house.
Why is one quote thousands of dollars below another?
Almost always scope rather than rate. Check restoration level, permits, fixture count and whether outdoor lines are included before treating two totals as comparable.
