Older homes in Kanata may still contain Poly B plumbing, a flexible grey plastic pipe commonly installed from the late 1970s through the 1990s. Although these pipes may appear intact, aging Poly B pipes can develop pinhole leaks, brittle sections and unexpected failures that lead to water damage.

An optional video consultation may help us identify visible grey plastic pipes or problem areas before the visit. During the on-site inspection, we confirm whether your home has Poly B and assess the layout of the existing plumbing.
A sewer or main-line camera inspection may also be recommended when drainage or under-slab conditions could affect the replacement plan.

Most smaller jobs require no deposit or upfront payment. Payment terms for larger projects are discussed during the proposal stage.
Before the replacement process begins, we protect flooring, nearby fixtures and personal belongings. Work areas are isolated where practical to control debris and reduce unnecessary disruption.
Our team disconnects or removes the affected polybutylene pipes and installs PEX or copper. Copper or brass fittings and approved PEX fittings are used where appropriate for the selected system.
We test the new system for water pressure, leaks, hot water delivery and proper fixture operation. The completed work is checked against applicable national plumbing code requirements.

Real feedback from our valued customers based on their genuine experience with Lister Plumbing.
Polybutylene was once used as an affordable alternative to copper. Over time, chemicals commonly found in municipal water supplies may affect Poly B pipes and plastic fittings from the inside.
Other factors can also contribute to failure, including:
High water pressure
Heat from hot water lines
Installation quality
Tight bends or stressed fittings
Reactions with other chemicals
Age and long-term material deterioration
Poly B plumbing can develop small pinhole leaks or fail suddenly. Because many pipes are concealed behind drywall, ceilings or flooring, a leak may cause significant property damage before it becomes visible.
Replacing Poly B can help homeowners avoid repeated pipe repairs, damaged walls, mould concerns and other costly repairs.
Lister Plumbing commonly replaces Poly B with cross-linked polyethylene, better known as PEX, or with copper.
PEX is a flexible modern solution that can often be installed through finished areas with fewer connections and less drywall removal. It offers a long life expectancy when properly installed and is widely used in modern residential plumbing systems.
Copper is a durable replacement material that may be recommended for visible piping, mechanical rooms, utility areas and other sections where rigid pipe is preferred.
We evaluate the home, existing layout and project budget before recommending the most appropriate replacement material.
Partial pipe replacement may be suitable when Poly B is limited to one accessible area or when the immediate issue involves a specific section.
However, repairing one leak does not address Poly B pipes in other parts of the home. If the entire system contains Poly B, many homeowners choose full replacement to reduce the likelihood of repeated failures and ongoing repair costs.
Our team will explain the advantages, limitations and cost of each option after inspecting the property.
Most Poly B replacement projects require access to basements, utility rooms, ceilings or selected wall areas. We carefully map pipe routes and choose practical access points to minimize openings.
When drywall must be removed, we keep cuts as limited and organized as possible. Lister Plumbing can coordinate drywall repair or recommend qualified professionals to restore affected surfaces after the plumbing work is complete.
We also protect floors, furniture and personal belongings throughout the project and clean the work areas before the final walkthrough.
Poly B replacement cost varies depending on:
The size and layout of the home
The total length of Poly B piping
Accessibility behind walls and ceilings
The selected replacement material
Under-slab pipe locations
Drywall repair requirements
Hot water tank or fixture reconnections
Whether full or partial replacement is selected
Lister Plumbing provides upfront pricing with no hidden fees. Free quotes are available for larger projects, and an optional small booking incentive may be offered.
We accept e-transfer, cash and cheque. Smaller projects generally require no upfront payment. Payment terms for larger replacement projects are discussed during the proposal stage.
Project timelines vary depending on the size of the property, the amount of piping involved and how easily the pipes can be reached.
A smaller or sectional replacement may be completed relatively quickly. A complete residential Poly B plumbing replacement typically requires several days, while projects involving under-slab work, multiple units or extensive wall access may take longer.
Lister Plumbing provides a specific schedule estimate with every quote so you understand when work begins and how long the project is expected to take.
Some insurance companies consider Poly B plumbing a potential red flag because of its history of leaks and failures. Depending on the insurer and the condition of the home, the presence of Poly B may affect coverage, premiums or renewal requirements.
Replacing the entire system may help address an insurer’s concerns, but it does not guarantee lower insurance premiums or automatic coverage. Homeowners should confirm requirements directly with their insurance provider.
Documentation showing that a professional plumber replaced the Poly B pipes may also be useful when selling or refinancing the property.

What is Poly B and why should I be concerned?
Poly B, or polybutylene, is a flexible grey plastic pipe installed in many homes from the late 1970s through the 1990s. Chemicals commonly found in municipal water supplies may contribute to internal deterioration, brittle failures and pinhole leaks. Replacing Poly B can reduce the risk of water damage, property damage and repeated costly repairs.
How do I know if my home has Poly B pipes?
Look for flexible grey plastic pipes in the basement, near the hot water tank, beneath sinks, behind access panels or above unfinished ceilings. Some Poly B pipes are concealed behind walls, so a professional plumber may be needed to confirm what materials are present. A sewer or main-line camera inspection may also be recommended when other hidden plumbing issues are suspected.
What are my replacement material options?
The most common options are PEX and copper. PEX, or cross-linked polyethylene, is flexible, durable and widely used in modern residential plumbing systems. Copper is a proven rigid material with a long life expectancy. We recommend a replacement material based on the home’s layout, local requirements and project needs.
How disruptive is the Poly B replacement process?
Most replacements require access to basements, utility rooms, ceilings and selected wall sections. Our team protects floors and personal belongings and carefully plans access to minimize disruption. When drywall repair is required, we can coordinate the repair work or recommend qualified contractors.
Will my insurance company require Poly B replacement?
Insurance requirements vary. Some insurance companies may decline coverage, apply conditions or charge higher premiums when a home has Poly B plumbing. Replacing the system may address this concern, but homeowners should speak directly with their insurer because replacement does not guarantee coverage or lower insurance premiums.
How long does replacement typically take?
Timelines vary depending on the home’s size, pipe access and project scope. Smaller sectional replacements may be completed more quickly, while most complete residential Poly B replacements require several days. More complex projects may take longer. A specific schedule estimate is provided with every quote.
What is the Poly B replacement cost?
The cost to replace Poly B depends on the total pipe length, home layout, accessibility, replacement material, under-slab work and drywall requirements. Lister Plumbing provides a detailed, upfront quote after inspecting the property. Free quotes are available for larger jobs.
Do you offer a warranty on Poly B replacement?
Yes. Lister Plumbing offers a one-year workmanship warranty on labour for Poly B replacement work. Material warranties vary by product and manufacturer.
Do you handle under-slab plumbing and sewer-line issues?
Yes. We perform under-slab plumbing repairs, pipe rerouting and sewer or main-line camera inspections from the house to the street. These services may be incorporated into a Poly B replacement project when hidden pipes or drainage conditions need to be assessed.
Will you use copper or brass fittings on replacements?
We use approved fittings suited to the selected replacement material. This may include copper or brass fittings for copper sections and reliable fittings designed for PEX pipes. All work is completed according to applicable plumbing standards.
Can you replace only sections of Poly B piping?
Yes. We can replace individual sections when partial replacement is practical. However, many homeowners choose full replacement when Poly B is present throughout the home because repairing one area does not eliminate the risk of future leaks elsewhere.
Will replacing Poly B affect my hot water tank or water heater?
The existing hot water tank may need to be disconnected and reconnected during the replacement process. We can also install or reconfigure electric hot water tanks and electric tankless water heaters when required. Replacement of the water heater itself is not always necessary.
Do you offer help with drywall repair after pipe replacement?
Yes. We keep wall openings as limited and organized as possible and can coordinate drywall repair after the plumbing work. We may also recommend trusted repair professionals depending on the scope and location of the openings.
How do you help prevent future costly repairs?
We replace aging Poly B with modern materials, use approved fittings and perform pressure testing before the new system is placed into service. We also inspect connections, hot water delivery and visible plumbing components to confirm the completed system is operating correctly.
