The answer to 'average cost of repiping' is that the cost can vary significantly depending on several factors. Typically, the cost of repiping a home can range from a few thousand dollars to tens of thousands, depending on the size of the home, the materials used, and the complexity of the job.
Some key factors that affect the cost of repiping include the age and condition of the existing plumbing, the accessibility of the pipes, the type of materials used (e.g., copper, PEX, or CPVC), the number of fixtures and bathrooms, and the local labor rates. Homes with multiple stories or difficult-to-access areas will generally cost more to repipe than single-story homes with easy access.
