Whole-House Repipe Cost in 2026: What Homeowners Pay
Key Takeaways
- A whole-house repipe costs $4,500 to $15,000 in 2026, with a national average near $7,500 for a typical single-family home.
- PEX repipes run $4,000 to $9,000; copper repipes run $8,000 to $15,000 or more because of higher material and labor costs.
- Home size, number of bathrooms, pipe material, and wall access are the four biggest factors that move the final price.
- Repeated leaks, rusty water, and low pressure throughout the home usually signal system-wide failure that repiping fixes.
- A home warranty helps cover a specific covered pipe failure, but a full repipe from aging pipes typically falls outside standard coverage.
A whole-house repipe costs $4,500 to $15,000 in 2026, with most homeowners paying around $7,500. The price depends mainly on the pipe material you choose, the size of your home, the number of bathrooms, and how easy it is for plumbers to reach the existing pipes. PEX repiping is the budget-friendly option at $4,000 to $9,000, while a copper repipe runs $8,000 to $15,000 or more. Repiping replaces all the water supply lines in a house, so it is a major project usually driven by aging galvanized steel pipe, repeated leaks, or corroded plumbing that keeps failing.
How Much Does a Whole-House Repipe Cost in 2026?
A whole-house repipe is a full replacement of a home’s water supply lines that costs $4,500 to $15,000 in 2026, averaging about $7,500. Most single-family homes fall between $6,000 and $9,000 when using PEX. The total combines materials, labor, permits, and drywall repair. Larger homes with more fixtures and finished walls sit at the higher end.
Plumbers often price repipes per fixture, roughly $500 to $800 for each sink, toilet, tub, and appliance connection. According to home-services cost data from Angi, labor makes up the majority of a repipe bill because the work is time-intensive and requires opening walls.
| Home Size | Bathrooms | PEX Repipe | Copper Repipe |
|---|---|---|---|
| 1,000-1,500 sq ft | 1-2 | $4,000-$6,000 | $8,000-$10,000 |
| 1,500-2,500 sq ft | 2-3 | $5,500-$8,500 | $9,500-$13,000 |
| 2,500-3,500 sq ft | 3-4 | $7,500-$11,000 | $12,000-$18,000 |
| 3,500+ sq ft | 4+ | $10,000-$15,000 | $16,000-$25,000 |
What Affects Whole-House Repipe Cost?
Whole-house repipe cost is affected by material choice, home size, the number of bathrooms and fixtures, wall access, the number of stories, local labor rates, and permit fees. The same house can vary by thousands of dollars depending on how much drywall must be opened and patched to reach the pipes.
- Pipe material: PEX is the least expensive; copper costs the most; CPVC lands in the middle.
- Home size and fixtures: more square footage and more bathrooms mean more piping and connections.
- Wall and slab access: finished walls, slab foundations, and tight crawl spaces add labor hours.
- Number of stories: two-story homes require vertical runs and more access points.
- Permits and inspection: most municipalities require a permit, adding $150 to $500.
- Drywall and finish repair: patching, texturing, and painting can add $500 to $2,500.
PEX vs Copper vs CPVC: Repipe Cost by Material
Repipe material determines both price and lifespan. PEX is the most affordable and fastest to install, copper is the most durable and expensive, and CPVC sits between the two. The table below compares the three most common repipe materials on cost and expected service life.
| Material | Typical Whole-House Cost | Expected Lifespan | Best For |
|---|---|---|---|
| PEX | $4,000-$9,000 | 40-50 years | Most homes; budget and speed |
| CPVC | $5,000-$11,000 | 50-75 years | Hot-water lines, mixed budgets |
| Copper | $8,000-$15,000+ | 50-70 years | Long-term durability, resale |
Signs You Need a Whole-House Repipe
Signs you need a whole-house repipe include repeated leaks, discolored water, and low pressure across multiple fixtures at once. When leaks start appearing in more than one location within a year, the pipe system itself is usually failing rather than one isolated section.
- Rusty, brown, or metallic-tasting water from several taps
- Two or more pipe leaks in the same year
- Low water pressure throughout the home, not just one fixture
- Visible corrosion, flaking, or pinhole leaks on exposed pipe
- Galvanized steel or polybutylene piping installed before 1975
If you are seeing pressure problems at a single faucet instead, the cause is often localized. Our guide to low water pressure causes and fixes can help you tell the difference before you commit to a full repipe.
The Whole-House Repipe Process, Step by Step
The repipe process is the sequence a licensed plumber follows to replace a home’s supply lines, from inspection through final inspection. Most repipes follow the same five stages regardless of material.
- Inspection and quote: the plumber maps the plumbing, counts fixtures, and estimates cost.
- Permit and prep: permits are pulled and access points in walls and ceilings are marked.
- Installation: new PEX, CPVC, or copper lines are run to every fixture and appliance.
- Testing and inspection: lines are pressure-tested and checked by a municipal inspector.
- Patch and finish: drywall is patched, textured, and painted to restore the walls.
Does a Home Warranty Cover a Whole-House Repipe?
A home warranty generally does not cover a whole-house repipe, because repiping replaces aging or corroded pipes system-wide rather than fixing a single covered breakdown. Coverage is typically provided for a specific covered plumbing pipe leak or break caused by normal wear, not for wholesale replacement of a deteriorating system or for pre-existing conditions.
That distinction matters: if a covered supply line fails suddenly from ordinary use, a plan like Empire Home Protect can help cover the repair of that failure, with the work carried out by an independent service technician. A planned upgrade because your galvanized pipes have simply reached the end of their life, however, is considered a maintenance and replacement project the homeowner budgets for. To compare providers before you buy, see our 2026 home warranty rankings, and review how much a home warranty costs to weigh the value.
How to Reduce Whole-House Repipe Costs
You can reduce repipe costs by choosing PEX, bundling drywall repair, getting multiple quotes, and scheduling during a contractor’s slower season. Getting at least three written estimates is the single most effective way to lower the price, since labor rates vary widely by company.
- Choose PEX unless you specifically need copper for resale or heat tolerance.
- Collect three or more written, itemized quotes from licensed plumbers.
- Ask whether the crew handles drywall repair in-house to avoid a second contractor.
- Combine the repipe with other planned plumbing work to save on access labor.
- Keep up with routine plumbing maintenance so smaller repairs do not snowball into a full repipe.
For water-efficiency rebates that can offset part of a plumbing upgrade, check the EPA WaterSense program in your area.
Frequently Asked Questions
How much does it cost to repipe a whole house in 2026?
A whole-house repipe costs $4,500 to $15,000 in 2026, with a national average near $7,500. PEX repipes run $4,000 to $9,000, while copper repipes run $8,000 to $15,000 or more. Home size, number of bathrooms, pipe material, and wall access are the biggest cost drivers.
Is PEX or copper cheaper for a repipe?
PEX is cheaper than copper for a whole-house repipe, typically saving 40% to 60% on total cost. PEX runs $4,000 to $9,000 for an average home, versus $8,000 to $15,000 for copper. Copper lasts longer and resists heat better, but PEX installs faster with fewer fittings.
How long does a whole-house repipe take?
A whole-house repipe takes 2 to 5 days for most single-family homes. A one-story home with open access can be repiped in 1 to 2 days, while a two-story home with finished walls may take up to a week including drywall patching and inspection.
Does a home warranty cover a whole-house repipe?
A standard home warranty generally does not cover a full whole-house repipe, because repiping addresses aging or gradually corroding pipes rather than a single covered failure. Coverage is typically provided for a specific covered plumbing pipe leak or break from normal wear, not system-wide replacement.
What are the signs I need to repipe my house?
Common signs include repeated leaks, discolored or rusty water, low water pressure throughout the home, visible corrosion on exposed pipes, and galvanized steel piping over 50 years old. Multiple leaks in a short period usually signal system-wide failure rather than an isolated problem.
Can you repipe a house without tearing up all the walls?
Yes. Experienced plumbers minimize wall damage by opening small, strategic access points rather than removing entire walls. PEX is flexible and can be routed through existing cavities, reducing openings. Expect some drywall patching, but a full teardown is rarely necessary.
