Whole House Repiping Cost: What Homeowners Pay

Whole house repiping means replacing every water supply line in your home, from the main shutoff valve to the last fixture. It is a big project, but it is also a permanent fix for pipes that are corroded, leaking, or too narrow to handle a modern household. Most homeowners pay somewhere between $4,000 and $15,000, with a national average of roughly $8,000 for a typical single-family home.

The exact number depends on your home’s size, the pipe material you choose, how easy the pipes are to reach, and local labor rates. This guide breaks down the real costs, the factors that move the price up or down, and the steps that help you avoid surprises.

What Whole House Repiping Means

Repiping is not a repair. It is the full replacement of the pipes that carry clean water into your home. In many projects, only the supply lines are replaced. Drain and sewer lines are a separate job and are usually priced on their own.

A complete repiping job typically includes:

Removing or abandoning old pipes, such as galvanized steel or polybutylene
Installing new pipes throughout the walls, ceilings, crawlspaces, and basement
Connecting the new lines to the main water valve and every fixture
Patching drywall and repairing small access holes
Testing the system and restoring water pressure

Average Whole House Repiping Cost

Costs vary widely by region and home type, but these ranges give a realistic starting point for a single-family home. Homes with two or more bathrooms generally sit at the higher end.

Scope of Work	Typical Cost Range
Small home, one bathroom, easy access	$2,500 – $6,000
Average home, two bathrooms	$4,000 – $10,000
Large home, three or more bathrooms	$8,000 – $15,000
Complex job with slab access or historic walls	$12,000 – $20,000+

Many plumbers also quote a per-fixture price. A common range is $300 to $800 per fixture, which is a quick way to estimate your total before an on-site visit.

What Drives the Total Cost

Pipe Material

The material you choose is one of the largest single cost factors. Copper is durable and long lasting but costs more in materials and labor. PEX is flexible, faster to install, and generally the most affordable option. CPVC sits in the middle.

PEX: roughly $4,000 – $12,000 for a whole house
CPVC: roughly $4,000 – $11,000
Copper: roughly $5,000 – $18,000

Home Size and Layout

More bathrooms, kitchens, laundry rooms, and outdoor spigots mean more pipe and more connections. Long runs from the water main to the far side of the house add cost. Homes with multiple stories also take longer to complete.

Accessibility

This is the factor homeowners underestimate most. Pipes in an open basement or crawlspace are quick to reach. Pipes buried in a concrete slab, behind tile, or inside finished walls require cutting and patching, which can add thousands of dollars.

Labor and Permits

Labor usually makes up 40% to 60% of the total bill. Rates vary by market, and skilled trades in busy areas charge more. A plumbing permit and required inspection are typically separate line items ranging from $100 to $500 or more.

Wall and Finish Repair

Plumbers open walls but rarely restore them. Drywall patching, texture matching, paint, and tile repair are usually handled by other trades and are often billed separately.

Costs Often Left Out of Initial Quotes

Drywall, paint, and tile repair after pipes are run
Temporary water shutoff or short hotel stays in rare cases
Replacing old shutoff valves, faucets, or supply stops
Landscaping repair if an exterior line is trenched
Disposal fees for old pipe and debris
Permit and inspection fees

Ask every contractor upfront whether these items are included. A quote that lists them separately is not necessarily more expensive, but it is clearer.

Signs Your Home May Need Repiping

Discolored or rusty water, especially after a vacation
Frequent leaks in different parts of the house
Low water pressure that does not improve after cleaning aerators
A metallic taste in drinking water
Visible corrosion, flaking, or dimpling on exposed pipes
Pipes that are 40 to 50 years old or older
Repeated repairs that add up to a large share of a repiping bill

How to Reduce Your Repiping Cost

Get at least three written estimates. Compare line by line, not just the bottom line.
Bundle the work. Replacing a water heater, shutoff valves, or fixtures during the same project can lower overall labor.
Choose PEX where allowed. It is often the least expensive reliable option and installs faster.
Handle your own cosmetic repairs. Painting and patching on your own can save a meaningful amount.
Schedule in the off-season. Slower months may bring more flexible pricing.
Ask about a per-fixture price. It makes comparisons between bids much easier.

Repiping vs. Repairing

If you have one isolated leak, a repair is usually the sensible choice. If you have had three or more leaks in two years, or your pipes are past their expected lifespan, repiping often costs less over time than repeated emergency calls. Emergency visits, water damage, and mold remediation can quickly exceed the price of a planned repiping project.

How to Get an Accurate Quote

Describe your home’s age, size, and number of bathrooms.
Ask what material is proposed and why.
Confirm whether permits, inspections, and drywall repair are included.
Ask how long the job will take and how water will be handled.
Request the warranty length for both parts and labor.
Get everything in writing before any work begins.

Bottom Line

Whole house repiping costs most homeowners between $4,000 and $15,000, with the final price set by pipe material, home size, and how hard the pipes are to reach. Plan on the average middle of about $8,000, then adjust for your home’s layout and your region’s labor rates. Get several written estimates, confirm what is included, and treat the project as a long-term upgrade rather than a quick fix.
