How Much Does It Cost to Repipe a House? [2026 Data]

In 2026, the national average cost to repipe a house is $7,500. Most homeowners spend between $1,500 and $15,000, depending on home size, pipe material, and the extent of the repiping work. Repiping a single fixture costs considerably less, with most homeowners spending an average of $1,200 per fixture depending on the amount of piping required.

Repiping a House Cost Factors: What Affects the Price?

Repiping a house involves several cost factors, with labor consistently accounting for about 70% of your total bill. The size of your home, the pipe material you choose, how accessible your existing pipes are, and the number of fixtures all influence the final price.

Size of the House

The size of your home is one of the most direct drivers of repiping cost, since larger homes require longer pipe runs and have more fixtures to connect. Multi-story homes add further cost because reaching plumbing fixtures between floors demands more piping material than a single-story layout.

Number of Plumbing Fixtures

Every fixture in your home, including toilets, sinks, and showers, requires its own piping, so the more fixtures you have, the higher your repiping cost. Rough-in plumbing for a bathroom is particularly expensive because routing pipes to precise locations is more labor-intensive than running them behind walls. See how plumbing fixtures affect your total cost of repiping a house in the breakdown below:

Type of Pipe Material

The three main piping materials, PEX, CPVC, and copper, vary significantly in price, with costs ranging from $0.40 to $8 per linear foot depending on which you choose. PEX is the most affordable option at $0.40 to $2 per linear foot, while CPVC runs $0.50 to $1 per linear foot. Copper is the most durable and bacteria-resistant choice but costs $2 to $8 per linear foot. Piping material plays a major role in the total cost of repiping a house, as shown in the table below:

• PEX Pipes: PEX pipes, or cross-linked polyethylene pipes, are flexible, won't corrode, and it's less likely these pipes will freeze. They also resist deterioration from scale and chlorine buildup. PEX piping ranges from $0.40 to $2 per linear foot .

• CPVC Pipes: These common residential pipes require cemented joints to make various angles. CPVC has a lower temperature limit than other piping and costs $0.50 to $1 per linear foot .

• Copper Pipes: These pipes are the most durable and resistant to bacteria and won't deteriorate from UV exposure. However, they can burst if it freezes and need pipe insulation. Copper piping ranges from $2 to $8 per linear foot .

Diameter of Piping

Pipe diameter affects cost because larger diameters require more material and are priced higher within the same pipe type. Drain lines are wider than water supply lines, but since most drain lines use PVC rather than copper, drainpipes typically remain more affordable than supply lines despite their larger size.

Accessibility

Pipe accessibility directly affects your repiping cost, with hard-to-reach locations adding significant labor time and expense. Pipes buried under concrete, for example, cost considerably more to remove and replace than pipes located behind drywall.

Permits

Most repiping projects require a permit, including situations where you are adding plumbing to a new build or changing your home's layout, with permit fees ranging from $50 to $500 depending on your region. Your plumber can confirm what your municipality requires before work begins.

Labor

Labor is the largest single expense in a repiping project, typically accounting for about 70% of your total cost, or around $5,250, and covering tasks such as accessing pipes behind walls, repairing drywall, excavating and repouring concrete, maneuvering pipe through wall openings, sweating pipe connections, and installing new piping for relocated fixtures. Labor rates also vary by location, with higher costs in cities where the overall cost of living is greater.

• Accessing pipes behind walls

• Repairing drywall after pipe replacement

• Excavating concrete to expose pipes in the foundation

• Repouring concrete to repair the foundation

• Maneuvering new lengths of pipe into small wall openings

• Sweating dozens of pipe connections

• Installing new piping to relocate fixtures

It's also worth mentioning that labor prices vary based on location, with higher labor prices in cities with a higher cost of living.

Drywall Repairs

Drywall repairs cost around $300 for small fixes and up to $900 or more for larger projects or full replacements, and repiping always requires opening walls to access the pipes. If your old pipes have caused leaks or flooding, the resulting drywall damage can push your repair scope and cost toward the higher end.

Soil Conditions

Soil conditions can affect repiping costs when buried lines are involved, such as water mains, underground pool lines, and sprinkler lines. Clay soil, for example, shifts over time and can complicate installation, driving up labor costs for those specific replacements.

Mobile Home Repiping

Repiping a mobile home costs between $1,500 and $4,000, which is less than a standard house because mobile homes contain less overall piping. The cost to replumb a mobile home varies based on the home's size and the number of fixtures involved.

Inspection Cost

When a permit is required, a post-project inspection is typically mandatory to confirm the work meets code, and in most cases that initial inspection cost is bundled into the permit fee. If an issue is found and a reinspection is needed, expect to pay $25 to $150 for that follow-up visit.

Repiping a House Additional Costs: What to Budget For

Beyond the core repiping work, additional services like water main replacement or a new water heater installation can meaningfully affect your total budget. The table below shows how costs break down by common add-on type.

Water Main Replacement

Water main replacement costs between $600 and $2,500 when the line running from your home to the street needs to be replaced alongside your interior repiping. Depending on your jurisdiction, your municipality may be responsible for maintaining or replacing the water main, so confirm local responsibility before budgeting for this expense.

New Water Heater Installation

Replacing a water heater costs about $850 to $1,750 on average, and pairing this work with a full repipe is a common and practical choice. Most homes use a tank water heater, which runs $600 to $2,500, while tankless water heaters cost $1,200 to $3,500 but last roughly a decade longer and operate more efficiently, making an upgrade potentially cost-effective when a plumber is already on-site repiping your home.

Signs You Need New Pipes in Your Home

You turn on the faucet, and discolored water pours out. Or perhaps you’re taking a shower and notice an unusual smell coming from the showerhead. Even a small leak here or there isn’t something to ignore. These could be important warning signs that you need new pipes.

• Water Pressure Is Too High or Too Low: Low water pressure can indicate a pipe blockage or leak. High water pressure can put too much stress on the plumbing system and promote pinhole leaks. If the water pressure isn’t just right, it might be time for pipe replacement. 

• Contaminated Water: If water is discolored or tastes or smells strange, it could be contaminated by worn-out pipes or debris. Rust can cause the water to turn brown, orange, red, or yellow, leading to a smell like rotten eggs. If the water is discolored for just a moment after turning the faucet on, the city could have recently worked on the water lines. 

• Visible Pipe Damage: If you notice cracked, leaking, or corroded pipes (or other visible damage), they will need replacing. 

• Recurring Leaks: You’ve patched up a leaky pipe or replaced a small section but keep finding leaks. This could indicate the pipes are deteriorating, meaning it could be time to repipe the house.

• Water Temperature Fluctuations: If the water temperature is fluctuating, it could be an issue with the pressure-balancing valves, water heater, or corrosion or buildup inside the pipes. You’ll need a plumber to identify the plumbing problem, and repiping may be the best solution.

• Old Pipes: If you have galvanized or lead pipes or pipes over 60 years old and nearing the end of their life, your home could be overdue for a pipe replacement.
