What Does Whole-Home Repiping Cost?
Replacing all of the water supply pipes in a home typically costs $4,000 to $18,000, averaging around $8,000. The range reflects significant variation in home size, pipe layout complexity, and the number of fixtures served.
Small or Single-Story Home: $4,000 to $7,000
A single-story home of 1,200 to 1,800 square feet with 2 to 3 bathrooms, a kitchen, and a laundry room has fewer fixtures and simpler pipe routing than a larger multi-story home. Repiping this size home with PEX typically takes a crew of 2 to 3 plumbers 2 to 3 days. The lower wall access complexity (one-story walls are easier to work in than two-story walls) and fewer total linear feet of pipe keep the project in the $4,000 to $7,000 range.
Average Two-Story Home: $7,000 to $11,000
A two-story home of 1,800 to 2,800 square feet with 3 to 4 bathrooms and a full kitchen and laundry has more fixtures, longer pipe runs, and more complex wall access (second-floor bathroom pipes must be routed from the basement or first floor). The project typically takes 3 to 5 days. The average US home repiping project falls in this range at approximately $8,000 for a standard 4-person home with 2.5 baths.

Large or Multi-Story Home: $11,000 to $20,000
Larger homes (3,000+ square feet, 4+ bathrooms, multiple stories) have proportionally more fixtures, longer pipe runs, more complex routing, and more wall access work. Custom homes with difficult wall construction (tile, plaster, or log cabin construction) add further to the labor cost. Homes with multiple water heaters, multiple kitchens, or pool/spa supply lines are at the upper end of this range.

Planning Your Project Budget
The cost ranges in this article are based on industry data and are intended as planning benchmarks, not fixed prices. The actual cost for your project depends on your specific home, your local labor market, the current price of materials, and the scope the contractor confirms after a site inspection. (For more on this, see Signs Your Home Needs Repiping (Not Just a Repair).)
Always get at least two written quotes on equivalent defined scope before committing to any home services project. Wide price variation between quotes usually reflects differences in material quality, scope completeness (what is included and what is not), or contractor overhead and experience level rather than simple price competition.
Use the cost data in this article to ask better questions during the quoting process: What material is included? What does that per-square-foot or per-linear-foot rate include and exclude? Are permits, cleanup, and disposal included? What is the warranty on labor? These questions turn a quote into a comparable basis for decision-making. (For more on this, see Questions to Ask Before Signing a Repiping Contract.)
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
