When Should You Repipe Your House?
Replacing the plumbing in your home is one of the most significant investments a homeowner can make. Whether your pipes are corroded galvanized steel, failing polybutylene, or just past their expected lifespan, house repiping restores water pressure, eliminates discoloration, and protects against catastrophic leaks. This guide covers everything Canadian homeowners need to know about repiping costs, materials, timelines, and how to decide if it is time to act.
Most plumbing systems last between 40 and 70 years depending on the material. Homes built before 1990 with galvanized steel pipes are the most common candidates for full repiping. Polybutylene pipes, installed between 1978 and 1995, are another widespread concern across Canada due to their tendency to become brittle and fail without warning.

Signs that repiping may be necessary include discoloured or rusty water, low water pressure throughout the house, frequent leaks, visible corrosion on exposed pipes, and knocking or banging sounds when you turn on taps. If you are experiencing multiple symptoms, a professional inspection is the safest next step.
Repiping Materials: What Are Your Options?
PEX Piping
Cross-linked polyethylene (PEX) has become the standard replacement material for residential repiping across Canada. PEX is flexible, freeze-resistant, and significantly faster to install than rigid materials. It costs between $4 and $8 per linear foot for materials, making it the most budget-friendly option. PEX fittings are reliable, and the material carries a 25-year warranty from most manufacturers. For the vast majority of Canadian homes, PEX is the right choice.
Copper Piping
Copper remains the premium option for homeowners who want maximum longevity and resale value. Copper pipes typically last 50 years or more and are resistant to UV damage and corrosion. However, copper costs between $10 and $20 per linear foot, and installation requires skilled soldering, which increases labour time. Copper is often preferred for exposed runs and in homes where property value is a top priority.

Replacing Galvanized Steel
Galvanized steel pipes were the standard in Canadian homes built before the 1960s. Over decades, the interior of these pipes corrodes, reducing water flow and eventually causing complete blockages. If your home still has galvanized supply lines, replacement with PEX or copper is strongly recommended regardless of whether you are currently experiencing problems.
House Repiping Cost Breakdown
Repiping costs in Canada typically range from $3,500 for a small condo to $20,000 or more for a large multi-storey home. The total depends on your home size, the number of plumbing fixtures, pipe accessibility, and the materials you choose.
Cost by Home Type
Condos and townhomes are the most affordable to repipe, usually falling between $3,500 and $8,000. Single-storey bungalows and smaller homes typically cost $5,500 to $12,000. Two-storey family homes with multiple bathrooms and finished basements range from $8,000 to $15,000. Large custom homes or heritage properties with complex layouts can exceed $18,000, especially if wall and ceiling access is limited.
Regional Cost Differences
Labour rates vary significantly across Canada. Vancouver and Toronto tend to be the most expensive markets, with full-home repiping averaging $8,000 to $15,000. Calgary and Edmonton fall in the mid-range at $5,500 to $12,000. Smaller markets in the Prairies and Atlantic Canada typically see lower costs, though material prices are relatively consistent nationwide.
What Factors Affect Cost?
The biggest cost driver is accessibility. Pipes behind finished drywall, under concrete slabs, or in tight crawlspaces require additional demolition and restoration work. Drywall repair and repainting alone can add $500 to $2,000 to the total bill. Other factors include the number of bathrooms and kitchens, whether the home has in-floor heating, permit fees ($300 to $600 in most municipalities), and the material you select.
Labour vs. Materials: Where Does the Money Go?
On a typical residential repiping project, labour accounts for 50 to 60 percent of the total cost. A professional crew of two to three plumbers can complete most single-family homes in three to seven business days. The timeline depends on the home size, the complexity of the routing, and whether demolition and restoration are included in the scope.
Material costs include the piping itself, fittings, manifolds, mounting hardware, and any required transition fittings to connect new pipes to existing valve stacks or water heaters. PEX systems typically use a central manifold that simplifies the layout and makes future maintenance easier.
DIY Repiping: Is It Worth the Risk?
Full-home repiping is not a suitable DIY project for most homeowners. The work requires permits, professional pipe sizing calculations, knowledge of local plumbing codes, and proper pressure testing before walls are closed up. Improperly installed pipes can cause hidden leaks, mould growth, and reduced water pressure that may not become apparent until months after installation.
According to the National Association of Home Builders, plumbing failures are one of the leading causes of residential water damage claims in Canada. A professional repiping job includes warranty coverage, proper permits, and the restoration work needed to return your home to its original condition.
How Long Does Repiping Take?
Most repiping projects are completed within three to seven business days, depending on the home size and complexity. Condos and townhomes are typically finished in two to three days. Larger two-storey homes with finished basements may require five to seven days. The timeline includes demolition of affected walls and ceilings, pipe removal and installation, pressure testing, and drywall and paint restoration.
Your water supply is only interrupted for short periods during the actual pipe connections. Most crews aim to restore water service by the end of each workday so you have full use of your plumbing overnight.
Does Repiping Increase Home Value?
A recently repiped home is significantly more attractive to buyers, especially in markets where galvanized steel or polybutylene pipes are common. Many home inspectors flag outdated plumbing as a major concern, and buyers frequently request repiping credits or price reductions during negotiations. A professional repipe with proper documentation and permits provides peace of mind that can accelerate a sale and protect your asking price.
For homes with polybutylene pipes, repiping can also restore insurance eligibility. Several Canadian insurers refuse to cover homes with known polybutylene plumbing, or charge significantly higher premiums. Completing a repipe resolves this issue and opens up access to standard coverage rates.
What to Expect During the Process
A professional repiping project follows a structured process. It starts with an in-home assessment and written quote. Once approved, the crew schedules the work around your availability. On day one, they protect your floors and furniture, then open walls and ceilings where pipe runs are located. Old pipes are removed and new piping is installed, routed through the most efficient pathways to minimize wall openings.
After installation, the system is pressure-tested to verify there are no leaks. Walls and ceilings are patched, taped, and mudded. Once dry, the surfaces are sanded and painted to match the surrounding areas. The crew cleans the work area and walks you through the completed system before final sign-off.
