How this is worked out
The estimate looks at your home's size and number of bathrooms. The price goes up if you choose copper or CPVC pipe, if plumbers earn more in your state, if the house sits on a concrete slab, or if it has two floors. The three questions cover the size, the bathrooms and the state; a second floor, a slab and another kind of pipe can be added under “Want a closer estimate?” once you see your price.

Two plumbing companies supplied the pipe life spans: Repipe Solutions for copper, and Fuse Service for PEX and CPVC.
Which pipes are in your house?
Polybutylene: 1978 to 1995
Kitec: 1995 to 2007
Galvanized steel: up to the 1960s
Copper: from the 1960s to today
Cast iron: Drain pipe, mostly before the 1970s
Orangeburg: Sewer pipe, 1945 to 1972Waste water leaves the house through drain and sewer pipes made of cast iron or Orangeburg. A PEX repipe covers just the water lines, so those two pipe types get their own prices.
What affects the price of a PEX repipe?
Most of the bill pays for the plumbers' time. That is why the price depends so much on what plumbers earn where you live and on how your house is built.
Most homes take 2 to 5 days, and families can usually stay in the house while the crew works, as Repipe Solutions explains. If the house has a crawl space (a low open space below a raised floor), the plumber can get to the pipes easily. Other houses are built on a slab, a concrete floor poured right on the ground. The pipes run under or through the concrete, so getting to them takes more work and the job costs more.
Some costs are often extra, so ask which ones your price includes:
- The permit, the city's official permission for the work: $50 to $800.
- Fixing the walls afterward: $300 to $1,500.
- A new water main, the pipe that brings water in from the street: $600 to $2,500.
- A new water heater, if the old one is worn out: $850 to $1,750.
What does each pipe material cost?
Across the US, homeowners spend about $7,500 on average for a whole-house repipe, according to Angi. Cost guides agree that PEX is the cheapest of the three, CPVC costs a little more, and copper costs the most. Your own house may cost more or less, depending on its size, bathrooms and state.
CPVC is a stiff cream or tan plastic pipe that costs a little more than PEX. Copper is a metal pipe joined with melted metal (solder). It costs the most, because the pipe itself is expensive and joining it takes longer. Choosing copper instead of PEX usually adds $3,000 to $7,000.
The number of bathrooms affects the price about as much as the type of pipe does, according to Fuse Service, a plumbing company. That is why the calculator asks about both.
One leak, or the whole house?
Fixing one leak under a concrete floor (a slab leak) costs $2,000 to $4,000. If you keep getting leaks, weak water pressure or brown water in several rooms, replacing all the pipes at once usually makes more sense. Most repipes today use PEX, a bendable plastic pipe that is usually red for hot water and blue for cold, because it costs the least of the three common pipes.

What it costs to repipe a 3 bedroom house
The number of bedrooms doesn't change the price. What counts is the number of bathrooms and the size of the house, and most 3-bedroom houses have 2 bathrooms. A 2-bath house of about 1,800 square feet runs about $6,400 to $11,800 in PEX at average US plumber wages. Other sizes are listed under repipe cost by house size.
Questions people ask
Will insurance pay for a PEX repipe?
Home insurance usually doesn't pay for a repipe. Some repipe companies let you pay over 24 months with no interest, so ask about it when you call.
Any downsides to PEX plumbing?
PEX doesn't hold up outdoors, since sunlight can wear it down. Angi also notes that a few towns' building rules don't allow PEX at all.
How do I know which pipe I have?
The pipe identifier on this site helps you name your pipe by its color and feel. It shows eight kinds of pipe, including copper, PEX and older kinds that often need replacing. Not sure what you have? Call, and the repipe company will check when it sees your house.
