YOUR POLY-B PIPE REPLACEMENT EXPERTS
Household plumbing systems fail for a variety of reasons. Pipes, the pipe joints and connectors, all wear over time. Different types of piping and plumbing are made using different materials. One such piping material Poly B piping was popular in Greater Victoria between the late 1970's and mid 1990s. Poly B was originally used as it was viewed as a cheaper and better plumbing pipe then copper which would save builders time on installation and cost. Unfortunately Poly B piping has proven to be less durable then copper piping with a very short lifespan before major fails happen.
Poly B Piping has been known to break down in as little as ten years causing leaks in walls resulting in mold issues, and in extreme cases flooding.
Poly B Piping that is not replaced or repaired can:
-
lead to increase in in home insurance premiums.
-
cancelled insurance.
-
difficulty in selling your home.

Poly-B Pipe Replacement in Greater Victoria: What Every Homeowner Needs to Know
What Is Poly-B Plumbing?
​
Poly-B is a flexible plastic piping material that was widely installed in residential homes from approximately 1977 to 1995. It was popular with builders because it was lightweight, easy to install, and initially less expensive than copper.
Unfortunately, Poly-B pipes degrade over time. Chemicals found in treated municipal water — particularly chlorine — combined with heat from hot water systems cause the pipe material to break down internally. This deterioration often occurs without visible warning signs.
​
Why Poly-B Pipes Are a Serious Risk
​
Even when Poly-B pipes appear to be in good condition, they can fail suddenly and without notice. Common problems include:
-
Sudden pipe bursts leading to major water damage
-
Cracks and splitting at fittings, joints, and bends
-
Internal weakening of pipe walls
-
Increased risk of mold growth and structural damage
Because of these risks, many insurance companies now view Poly-B plumbing as a liability. Homeowners may face higher premiums, restricted coverage, or difficulty obtaining insurance until the pipes are replaced.
​
How to Tell If Your Home Has Poly-B Pipes
​
You may have Poly-B plumbing if:
-
Your home was built or renovated between 1977 and 1995
-
Your plumbing supply lines are flexible plastic, often grey, blue, or black
-
Pipes are stamped with markings such as “PB2110”
-
Poly-B piping is visible near the hot water tank, in crawlspaces, basements, or behind fixtures
If you’re unsure, a professional inspection can confirm whether Poly-B piping is present and assess its condition.
Repair vs. Full Poly-B Replacement
While repairing a single leak may seem like a cost-effective solution, spot repairs rarely provide long-term protection with Poly-B plumbing. Once one section fails, others are often close behind. Repairs do not address the widespread internal deterioration affecting the entire system and may still leave insurance concerns unresolved.
A full Poly-B replacement is the most reliable way to eliminate risk and protect your home.

How Much Does Poly-B Pipe Replacement Cost in Greater Victoria BC
​
If you've discovered Poly-B piping in your home, one of the first questions you're probably asking is: How much does it cost to replace Poly-B plumbing in Victoria?
​
The cost of a complete Poly-B pipe replacement can vary significantly from one home to another. Factors such as the size of your home, number of bathrooms and plumbing fixtures, accessibility of the existing piping, number of floors, and the amount of wall or ceiling access required can all affect the final cost.
​
As a general budgeting guideline, many Greater Victoria homeowners should expect a complete Poly-B replacement to cost approximately $8,000 to $15,000, although smaller and simpler homes may cost less and larger or more complicated homes can cost $18,000 or more.
​
Published 2026 BC pricing guides currently place many complete Poly-B replacement projects in the $6,000–$18,000 range, while Victoria-specific pricing information also shows that the condition and accessibility of each individual home can make a significant difference. These figures should be considered budgeting guidelines rather than a quote for your home.

-
Typical Greater Victoria home $8,000–$15,000
-
Larger home with multiple bathrooms $12,000–$18,000+

Why Can Poly-B Replacement Cost So Much?
Replacing Poly-B isn't simply a matter of pulling out old pipe and installing new pipe.
A complete repipe can involve:
-
Accessing existing water supply lines
-
Removing or abandoning old Poly-B piping
-
Installing new PEX or other approved replacement piping
-
Connecting every plumbing fixture
-
Replacing fittings and connections
-
Working around walls, ceilings, floors and cabinets
-
Pressure testing the new plumbing system
-
Repairing openings required to access the plumbing
-
Coordinating permits and inspections where required
The amount of work involved is why two homes of similar size can receive very different Poly-B replacement estimates.
What Factors Affect the Cost of Poly-B Replacement?
​
1. Size of Your Home
The larger the home, the more plumbing supply lines there are likely to be.
A smaller single-storey home with one or two bathrooms may require substantially less pipe and labour than a larger two- or three-storey home with several bathrooms, a kitchen, laundry room and additional plumbing fixtures.
2. Number of Bathrooms and Fixtures
Every bathroom, kitchen, laundry room and other fixture supplied by Poly-B can add to the scope of the replacement.
A three-bathroom home, for example, will generally require more connections and labour than a one-bathroom home.
3. Accessibility of the Existing Poly-B
Accessibility can have a major impact on the cost of a re-pipe.
If plumbing is accessible through a crawlspace, unfinished basement, utility room or other open areas, installation may be considerably easier.
​
If the existing Poly-B is concealed behind finished drywall, ceilings, flooring or cabinetry, additional access work may be required.
​
This is one reason an in-home assessment is much more useful than relying on an online Poly-B replacement calculator.
4. Number of Floors
A single-storey home may have a relatively straightforward plumbing layout.
A two- or three-storey home can require additional planning and labour to route new water supply lines between floors while minimizing disruption to the finished areas of the home.
​
5. PEX vs. Copper
Modern PEX is commonly used when replacing Poly-B because its flexibility allows plumbers to route new supply lines through many areas of a home efficiently.
Copper can also be used for residential plumbing applications but may have different material and installation costs.
The best replacement material depends on the home, plumbing configuration and homeowner preferences.
6. Drywall and Restoration
One of the most important questions to ask when comparing Poly-B replacement quotes is:
“What is included in the price?”
Some projects require openings to be made in walls or ceilings to access existing plumbing.
The plumbing portion of the project and the subsequent drywall repair may be handled separately, depending on the contractor and scope of work.
​
Make sure you understand whether drywall repair, painting and other finishing work is included before comparing one quote with another.
