How Much Does It Cost to Repipe a House?
Is repiping a house worth it?
Most homeowners pay $4,000 to $15,000 to repipe an average-sized home, with the national average around $7,500. Costs can run as low as $1,500 for a small partial repipe with PEX, or as high as $35,000 for a large home with copper pipe and difficult access. Material choice (PEX vs. copper) and labor, which makes up about 70% of the total bill, are the two biggest cost drivers.
For most homeowners, repiping is one of those expenses that comes out of nowhere. One day your pipes are fine, and the next you’re dealing with discolored water, low pressure, or a plumber telling you it’s time for a full replacement.
Key takeaways:
- A typical 1,500 sq ft home costs $6,500–$10,000 to repipe
- PEX runs $0.40–$2.00 per linear foot installed; copper runs $2.00–$8.00 per foot
- Labor makes up roughly 70% of the total bill, about $5,250 on an average project
- Homeowners insurance almost never covers repiping, since it’s treated as maintenance, not emergency repair
What drives that wide price range? Cost shifts significantly based on whether you go with budget-friendly PEX piping or premium copper, plus factors like labor, permits, and pipe accessibility that can quietly push your final bill higher than expected.
This guide breaks down everything that affects repiping costs, from material selection to labor rates, and how Krupp Whitney Plumbing’s Platinum Sewer Protection Plan can help offset the cost.
Average Cost to Repipe a House in 2026
National Cost Ranges and Averages
Most homeowners pay between $4,000 and $15,000 for a complete house repipe in 2026. The national average sits at approximately $7,500 for a full repipe in a 1,500 to 2,000 sq ft home with 10 to 12 plumbing fixtures, using PEX or CPVC. That estimate typically covers 1,200 to 1,600 linear feet of piping, basic permit fees, mid-range labor rates, and moderate drywall repair.
Labor alone makes up about 70% of your total project bill, with professional installation costs ranging from $1,250 to $22,000 depending on scope. Where you live also plays a role — labor rates in high-cost states like California can push comparable projects toward $30,000, while many other regions land closer to the national average.
Cost by Home Size
Home size is one of the biggest drivers of repiping cost.
|
Home Size |
Typical Repipe Cost |
|
Under 1,200 sq ft |
$1,500–$5,000 |
|
1,200–2,000 sq ft (medium) |
$4,000–$10,000 |
|
Over 2,000 sq ft (large) |
$8,000–$20,000+ |
|
Two-story homes |
$7,000–$15,000 |
For context, repiping cost per square foot ranges between $2.00 and $10.00. Two-story homes require additional pipe runs through floors and ceilings, which drives up both materials and labor hours.
Cost by Number of Fixtures
The number of plumbing fixtures in your home matters just as much as square footage:
|
Number of Fixtures |
Typical Repipe Cost |
|
Fewer than 9.5 fixtures |
~$4,614 |
|
12–14 fixtures |
$8,400–$9,800 |
|
15+ fixtures |
$10,500+ |
Each additional fixture means more pipe, more labor, and more time on the job.
Low-End vs. High-End Scenarios
Low-end scenarios involve homes under 1,500 sq ft with 6 to 8 fixtures, using PEX or CPVC where walls are already open or crawl space access is available. These projects fall in the $1,500 to $7,500 range.
High-end scenarios are a different story. Homes over 3,500 sq ft with 15 or more fixtures using copper pipe, slab foundations, or blocked wall access can require structural cuts and complex rerouting, pushing costs to $15,000–$35,000. Krupp Whitney Plumbing’s Platinum Sewer Protection Plan members receive exclusive discounts on repiping projects, which can make a meaningful difference at either end of that range.
Key Factors That Affect Repiping Costs
Material selection, how easy it is to access your existing pipes, and local permit requirements all play a role. Two homes of the same size can come in at very different price points depending on these variables.
Pipe Material Selection (PEX, Copper, CPVC)
Your choice of pipe material is one of the biggest cost drivers in any repiping project. PEX is the most affordable option, ranging from $0.40 to $2.00 per linear foot. CPVC falls in the middle at $0.50 to $1.00 per linear foot. Copper sits at the top end, ranging from $2.00 to $8.00 per linear foot. Copper installations cost 58 to 68 percent more than PEX because each joint requires skilled labor for soldering.
Home Size and Layout Complexity
Larger homes simply need more pipe. A single-story home under 2,200 sq ft may require 1,000 to 1,200 linear feet of pipe, while a two-story home over 3,500 sq ft could need more than 2,000 linear feet. Multistory homes cost more to repipe because piping has to travel between floors to reach fixtures.
Labor and Installation Costs
Labor makes up about 70% of your total repiping bill, roughly $5,250 on an average project. Professional plumbers charge between $45 and $200 per hour, and most whole-home repiping projects require 60 to 100 hours of labor depending on scope and access conditions. This isn’t a job where cutting corners on labor pays off; installation quality directly affects how long your new pipes last.
Accessibility of Existing Pipes
Where your pipes are located matters just as much as how many there are. Inaccessible or obstructed piping can add 10 to 30% to your total labor cost. Pipes buried under a concrete slab are significantly more expensive to remove and replace than pipes running behind drywall.
Permit and Inspection Requirements
Repiping your home almost always requires a permit. Fees vary by municipality, but most homeowners pay between $50 and $500. Skipping the permit process isn’t worth the risk. Code violations can surface during a home sale and create serious problems.
Complete Cost Breakdown by Material and Scope
Knowing the general price range is one thing. Knowing exactly where your money goes is another — material type and project scope are the two biggest variables that separate a $3,000 repipe from a $15,000 one.
Material Cost Comparison
|
Material |
Cost per Linear Foot |
Best For |
|
PEX |
$0.40–$2.00 |
Most budget-friendly; flexible, fast to install |
|
CPVC |
$0.40–$1.56 (installed: $0.75–$1.50) |
Mid-range durability and cost |
|
Copper |
$2.00–$8.00 |
Premium, longest track record; highest labor cost |
A 100-foot roll of 1/2-inch PEX costs $20 to $250, depending on brand and size. Within copper, Type L runs $1.00–$2.20 per foot, Type M runs $0.75–$1.25 per foot, and Type K runs 15–25% higher than Type L.
Full Repipe vs. Partial Repipe Costs
Not every repiping project has to cover the entire house. Partial repipe projects make sense when only a specific section of your plumbing is failing:
|
Project Scope |
Typical Cost |
|
Partial repipe (single section) |
$1,500–$5,000 |
|
Whole-house PEX |
$3,000–$8,000 |
|
Whole-house copper |
$5,000–$15,000+ |
The right choice depends on the condition of your existing pipes and how much of the system is showing signs of wear.
Drywall Repair and Restoration Costs
One cost homeowners often overlook is drywall repair. Plumbers need to open walls to access pipes, and putting those walls back together comes at a price. Small repair jobs start around $100 to $1,000, while larger projects with 10 to 30 or more holes typically range from $800 to $2,500 or more. Ask your contractor upfront what the restoration work will look like before the project begins.
Regional Price Differences
Location plays a real role in what you pay. National labor rates for repiping range widely — some lower-cost markets see whole-house projects around $4,500 to $11,500, while high-cost states like California can push comparable jobs toward $30,000. Labor rates, local permit requirements, and contractor availability all contribute to these regional gaps.
Does Homeowners Insurance Cover Repiping?
The short answer is no. Homeowners insurance almost never covers repiping because insurers treat it as preventive maintenance rather than emergency repair. Your policy may cover water damage caused by a burst pipe, but not the pipe replacement itself.
It gets more complicated from there: multiple water damage claims can raise your insurance rates or even trigger a policy cancellation. Some carriers specifically flag homes with galvanized or polybutylene pipes and may refuse to renew coverage until you repipe.
Ways to Offset the Cost
Repiping is a significant expense, but it doesn’t have to hit your wallet all at once. Ask about financing options and membership discounts — for example, Krupp Whitney Plumbing’s Platinum Sewer Protection Plan gives members access to discounts on repiping projects.
DIY vs. Professional Repiping
DIY repiping might seem like a way to cut costs, but it comes with real risk. It requires advanced plumbing skills, knowledge of local building codes, and the right permits — one mistake can lead to leaks, code violations, or denied insurance claims down the road. Professional installation ensures the work meets legal requirements and comes with warranty protection.
Long-Term Value and ROI
Repiping is not just a repair — it’s an investment. Updated plumbing eliminates recurring repair costs and prevents water damage that can run into the thousands to fix. Some insurance carriers even offer premium reductions for homes with modern piping systems, and homes with updated plumbing tend to move faster and hold up better under buyer inspections when it comes time to sell.
Frequently Asked Questions
How much does it cost to repipe a house?
Most homeowners pay $4,000 to $15,000 for a full repipe, with a national average around $7,500. Small partial repipes can run as low as $1,500, while large homes with copper pipe and difficult access can reach $35,000.
Is PEX or copper cheaper for repiping?
PEX is significantly cheaper — $0.40 to $2.00 per linear foot installed, versus $2.00 to $8.00 for copper. Copper installations typically cost 58 to 68% more than PEX overall because each joint requires skilled labor for soldering.
Does homeowners insurance cover repiping a house?
No, in almost all cases. Insurers treat repiping as preventive maintenance, not emergency repair. Insurance may cover water damage from a burst pipe, but not the cost of replacing the pipes themselves.
How long does it take to repipe a house?
Whole-house repiping typically requires 60 to 100 labor hours depending on home size and pipe accessibility. With a full crew, most projects are completed in roughly 3 to 5 working days.
Do I need a permit to repipe my house?
Yes, in almost every municipality. Permit fees typically run $50 to $500. Skipping this step risks code violations that can surface later, including during a home sale.
Is repiping a house worth it?
For homes with aging galvanized, polybutylene, or frequently leaking pipes, yes. It eliminates recurring repair costs, reduces water damage risk, can improve insurance standing, and tends to make a home more attractive to buyers.
The Bottom Line
Repiping your home is a significant expense, but it’s also one of the most practical investments you can make in your property. Material selection, home size, and pipe accessibility all play a role in what you’ll ultimately pay. Knowing what drives those costs puts you in a much better position to plan ahead and avoid surprises.
Updated plumbing protects your home from water damage, keeps your insurance situation in good standing, and makes your property more attractive to buyers down the road. The upfront cost is real, but so is the long-term payoff.
