Cost of Repiping a House

The average cost of repiping a house in the United States is about $7,500, though more extensive repiping projects can cost up to $15,000 or more. You can estimate repiping costs by counting the number of plumbing fixtures in your home and multiplying by $1,500. 

Factors That Affect House Repiping Costs

Below is a quick list of the main factors that will affect how much it costs to repipe a house.  

Size of House

The main factor affecting piping costs is the size of your home. The average repiping job costs about $4 to $6 per square foot but will ultimately depend on piping materials and intricacy. 

Number of Plumbing Fixtures

Every fixture in your home that connects to your plumbing will need new piping, including sinks, showers, toilets, and water heaters. The more fixtures you have, the higher the cost of the repiping project. 

Structural Changes

Repiping will cost more if you need to work around structural changes in your home. For example, if you want to change the location of your shower, you will most likely have to redo the entire orientation of the plumbing in your bathroom. Similarly, adding or removing walls during repiping can increase project costs. 

Piping Material

Most modern homes use one of three types of pipe materials: CPVC, copper, and PEX piping, and piping costs vary between them. Generally, copper is the most expensive to install and can cost up to $8 per foot. In contrast, CPVC and PEX piping is more affordable and costs about $0.50 to $1.00 per foot. 

Piping Accessibility

Pipes that are in difficult-to-reach locations will cost more to remove and replace. For example, some pipes in your yard or basement might require digging through concrete to access. 


Most plumbing alterations will require you to get permits before construction, especially if you plan to add additional plumbing fixtures. Permit costs differ depending on the project’s complexity, but they can cost anywhere between $50 and $500. Your plumbing installation team should handle pulling necessary permits for any projects. 


Permitted plumbing projects may also require inspections afterward to determine whether alterations and additions are up to code. Initial inspections are usually included in permitting fees, but you will have to pay for additional inspections if required. 

How Long Does It Take to Repipe a House?

Repiping an entire home is a big project and can take anywhere between a few days and a few weeks. You won’t be able to use your home’s plumbing during this time, so you will need to make alternative arrangements for things like cooking, showering, and laundry when the plumbing crews are in your home. Your plumber should consult you beforehand and give you a detailed room-by-room schedule before they start doing work. 

House Repiping ROI

Repiping homes can increase your home’s resale value, as old and outdated plumbing can be a liability for buyers. Also, if you plan to sell your home in the near future, performing a complete repiping can ameliorate any plumbing issues that might become a problem during the sales process, such as low water pressure or sewer leaks. Repiping gets ahead of these issues and can save you the hassle of eleventh-hour difficulties. 

Benefits of Repiping

Old cast iron piping is more susceptible to damage and corrosion, which creates leaks and water damage. Old pipes can also cultivate bacteria and other pathogens, so they may be actively harming your health. Iron pipes, in particular, are prone to rusting which can change your water’s color and give it a bad taste. 

Repiping your home updates your plumbing with durable materials that won’t corrode or degrade from regular use. You will also notice better plumbing performance after replacing outdated piping and fewer issues such as low water pressure.
