How Much Does It Cost To Repipe A House?


If your home is more than 30-50 years old, the pipes that bring water into your house could be in danger of leaking or bursting. With this, it’s essential to know how much it would cost to repipe a home so you know what to expect.

Repiping or replumbing means replacing the pipes in your house with new material. Repiping is usually required when the pipes are damaged, leaking, corroded, or if you want to upgrade from an older type of piping to a more modern and better type.

If you are looking to replace your old pipes with something new, this article can advise what type of material might work best and how much it might cost. So read on to learn more!

Average Cost To Repipe A House

Average Cost Range To Repipe A House

The average cost range to repipe a house is $1,500 to $8,000 for a regular house with 2-3 bathrooms. The total cost will depend on the size of your home, the type of pipes used, and whether you’re doing a partial or complete repipe.

The National Average Cost to repipe a house is around $4,000. The minimum cost of repiping a home is $1,500 for a smaller house with fewer pipes. The maximum cost of repiping a home can exceed $15,000, particularly if it involves a major overhaul of the piping system.

The estimated cost includes labour, materials, and necessary permits (if required). The cost of repiping a house can also vary from province to province due to labour rates and the availability of materials. Generally speaking, you’ll pay more for labour in some provinces than others, and you’ll find that certain types of plumbing pipes are much cheaper in some areas than others.

Factors That Affect The Cost To Replace Plumbing In A House

Replumbing a home can be expensive, and many factors can affect the cost of a repiping project. Here are some examples of the factors:

Size of the House

Larger houses are generally more expensive to repipe due to the amount of plumbing involved, resulting in more man-hours and higher materials costs.

In addition, larger houses may have complicated systems that will require extra work to replace, such as drainage pipes in multi-story homes or lengthy systems that run through walls and floors.

The Number of Fixtures

The more fixtures in a house, the higher the repiping cost will be. This is because each fixture needs to be disconnected and reconnected during the process, so each fixture adds more time and cost to the project.

Age of the House

Older homes are more likely to need complete replumbing, as the existing pipes may be made of outdated materials that are no longer up to code. For example, a poly-b pipe was a popular replacement for galvanized pipes during the 1970s and 1900s, but poly-b is now considered dangerous because it’s very prone to corrosion.

Also, older homes may have plumbing added over the years, which means there could be numerous cut-ins or interrupted lines due to remodeling projects. This means that all cutting must be re-sealed, which is time-consuming.

Location and Climate

The cost of replacing plumbing in a home can be impacted by location and climate. Homes with inaccessible pipes due to cramped crawl spaces or other factors may incur extra costs as well. In addition, some climates are more problematic than others when it comes to plumbing.

For example, homes in cold climates may have to deal with frozen pipes and the resulting water damage, while homes in earthquake-prone areas may need special seismic shut-off valves that meet local building codes.

Soil Conditions

The type of soil around a home can also affect the cost of repiping. Homes in areas of expansive clay soil may suffer from shifting and movement, which can affect plumbing pipes. In addition, homes with shallow water tables or properties that fall in flood zones will also require special considerations. This will only affect the price if you plan on re-piping your underground water lines. 

Permits and Inspections

In some areas, a repiping project may require permits and inspections. This typically entails an assessment of the pipe materials being used and a site-specific evaluation done by a professional in your area. In some cases, these services can add to the overall cost of repiping a house.

When it comes to repiping a house, many factors can vary the project’s cost. However, you can get the job done without breaking your budget with careful planning and a qualified contractor.

Cost for Different Types of Pipes

While repiping a house can vary depending on the factors mentioned above, there are also different costs associated with different types of pipes. Here are some of the most common types of pipes and their estimated costs.

PEX or Cross-Linked Polyethylene

PEX Piping Average Cost

The cost of PEX piping is typically around $1.50 to $5.00 per linear foot, making it one of the more affordable options on the market. In a 1000-square-foot home, the cost of PEX piping would be between $1,500 and $5,000+.

PEX is a type of plastic pipe that’s become increasingly popular in recent years. This piping is often considered to be the best option for homes because of the following benefits:

  • It’s flexible, so it can be snaked through existing walls and floors without too much difficulty.
  • PEX is more resistant to freezing and bursting, making it a better option for cold climates.
  • It has high heat tolerance, which makes PEX pipes an ideal choice for hot water lines.
  • PEX is also resistant to corrosion, so it’s less likely to develop leaks over time.

Copper Pipes

Copper Piping Average Cost

Copper pipes are among the most popular and reliable types of piping out there. However, they can also be one of the more expensive options. The average cost for copper piping is around $2.00 to $10 per linear foot, depending on the thickness of pipe used and other factors. 

Even copper piping is more expensive than PEX, this type of piping is considered to be a good investment because of the following benefits:

  • It is very reliable and is often used in homes with high water pressure.
  • It is resistant to both corrosion and leakage, making it a good long-term investment for many homeowners.
  • Copper pipes are generally easier to maintain than other types of piping since they don’t crack or corrode as easily.
  • While copper pipes are more expensive than PEX, they also have a longer lifespan and require less maintenance. This makes them a good choice for many homeowners, particularly those who are looking for a long-term investment.

Cost to Replace Poly B Plumbing
