As the first step you need to look through the home inspection report. You had to get it when you bought your house. There you can find information about pipes you have. If you do not have this report, we recommend you book a plumber for a pipe inspection.

If you live in areas with hard water, which has high mineral content, your pipes may worn-out sooner. If your pipes are older than these guidelines, it doesn’t necessarily mean they need to be replaced. Well-maintained pipes may last longer, and poorly maintained ones may fail sooner.

Replacement of Polybutylene Pipes

Polybutylene pipes are prone to frequent breakage and leakage. Replacing polybutylene pipes with stronger ones will save you a budget in the future. Polybutylene pipes were actively used in houses built between 1970–1990.

How Is the Price of House Repipe Formed?

The house repipe cost depends on several factors, such as: house size, the complexity of the plumbing system, the material from which the pipes are made, scope of work, location and accessibility of pipes, pipe diameter.

  1. House Size. The cost of repiping a small one-story house is low, as it requires fewer materials. A large house repipe with several bathrooms will cost more, as the amount of materials and complexity of work increase. It is most expensive to replace pipes in multi-storey buildings.
  2. The Number of Plumbing Fixtures. The more connections to the plumbing system, the higher the price of house repipe. In other words, the more toilets, sinks, dishwashers, showers, washing machines in the house, the more expensive the procedure will be. So, for a house with one bathroom, the cost of replacing pipes is significantly less than for a house with three bathrooms.
  3. Ease of Access to Pipes. The pipes behind the walls are easier to get to, so replacing them will be cheaper. On the contrary, the price increases if you need to climb into small confined spaces to access the pipes.
  4. Pipe Diameter. The larger the pipe diameter, the more material is required. Accordingly, the price of such a pipe also increases.
  5. Material of New Pipes. Copper pipes are the most expensive. The cost of one foot of copper pipe ranges from $2 to $4. Pipes made of PEX are cheaper: for one foot you will pay from $0.50 to $2.
Pipe Material Cost Per Foot
Copper Pipes $2–$4
Polyethylene Pipes (PEX) $0.50–$2
