How Much Does It Cost to Repipe a House?

Repiping your house is one of the most important investments you can make, especially when dealing with aging pipes, chronic leaks, or low water pressure. It’s especially important to look out for signs if you live in a home that is 20 years old or older.

Now, the looming question: The average cost to repipe a house ranges from $4,000 to $15,000+, depending on a few key variables:

  • Size of the home
  • Number of fixtures
  • Pipe material used (copper vs. PEX)
  • Accessibility of the plumbing
  • Local code requirements and permits

Larger houses with more bathrooms and complex layouts may be on the higher end, while smaller homes with accessible piping could be more affordable. Let’s break down the factors that dictate the total cost of repiping a house and how to make an informed decision for your job.

Home Size

Estimated Cost

Additional Notes

Small (1-2 bath)

$4,000-$6,500

PEX or CPVC recommended

Medium (2-3 bath)

$6,500-$9,500

Depends on access and fixture count

Large (3+ bath)

$10,000-$15,000

Copper repipes or multi-story homes on the high end

What impacts the cost to repipe a house?

Every home is different, and so is every repipe. Here are the top factors that impact cost:

1. Type of piping Material

To learn more about the typical cost of piping materials, check out our article comparing PEX and copper piping.

  • Copper piping is durable but more expensive. Cost can also increase due to labor time because of soldering and rigid installation.
  • PEX piping is flexible, affordable, and often easier to install. We recommend this for smaller, more modern homes.

If you’re unsure which piping material is best for your home, a licensed plumber should be able to educate you on your options and find the best fit.

2. Size and Layout of the Home

More square footage, stories, and fixtures = more water lines and longer pipe runs, which means more labor and material costs.

The cost of a repiping job for a one-story with one bathroom will be way different than for a two-story with 3+ bathrooms.

3. Wall and Floor Accessibility

Easier access to your pipes means fewer drywall cuts and less repair work afterward.

On the other hand, if plumbing runs behind walls, under slabs, or in crawlspaces, this increases labor costs. This is more common in older homes that were built without taking modern plumbing access in mind.

4. Additional Services Needed

If you have existing pinhole leaks, slab leaks, or need to relocate fixtures, this can add to the project scope.

Some homes may also require upgrades to match your new system, like new shutoff valves or water heater adjustments.

What’s Included in a Full House Repipe?

When you schedule a full house repipe, you’re not just getting new pipes. Here’s what’s typically included in a professional repiping job:

  • Replacement of hot and cold water lines throughout the home
  • Connection to all major plumbing fixtures (toilets, sinks, tubs, showers)
  • Installation of new shut-off valves where needed
  • Wall patching after pipe replacement (if required)
  • Permit acquisition and inspection coordination
  • Cleanup and removal of old piping

Some plumbers may charge extra for wall repair or fixture upgrades. Be sure to ask for a detailed scope in your estimate.

Repiping In Southern California: What You Should Know

Southern California presents a few unique variables for house repiping:

  • Hard water is common in many areas, especially in Riverside and San Bernardino counties, which can shorten the life of old pipes
  • Earthquake activity can affect the lifespan and integrity of rigid copper systems in older homes
  • Coastal cities face more corrosion due to salt air exposure
  • Cities like Los Angeles and San Diego may require stricter inspections and permits

Pro tip: If your plumbing is 20+ years old and you’re already dealing with leaks, it’s often more cost-effective to do a complete repipe than to keep patching failing systems.
