Home repair cost calculator
Estimate a planning range for repiping a house with PEX, copper, or CPVC before comparing plumber bids and wall repair assumptions.
Direct answer
Whole-house repiping often ranges from about $4,000 to $20,000+, with PEX usually lower than copper. The total depends on home size, bathroom count, stories, pipe access, wall openings, local labor, permits, and whether drywall patching, fixtures, or shutoff upgrades are included.

Estimate boundary
Local labor, permit rules, material availability, and contractor minimums can move the final bid above or below the calculator range.
Hidden conditions, project complexity, access, demolition, restoration, and inspection requirements should be confirmed by a local licensed contractor.
Insurance coverage, code compliance, rebates, and documentation rules vary by location, policy, carrier, and building department.
| Scope | Typical range | Best for | Confirm first |
|---|---|---|---|
| Small PEX repipe | $4,000-$9,000 | Smaller one-story homes | Fixture count and patching |
| Typical PEX or CPVC repipe | $8,000-$16,000 | Average homes with 2-3 baths | Wall openings and permit scope |
| Copper repipe | $12,000-$28,000+ | Higher-material bids | Copper grade, labor, and access |
| Difficult access repipe | $18,000-$35,000+ | Multi-story or finished-wall homes | Drywall, tile, and restoration |

Updated guidance
Published June 28, 2026. Last updated July 3, 2026.
Start with home size, bathroom count, and fixture density.
Apply PEX, copper, or CPVC material and labor assumptions.
Adjust for stories, wall openings, finished surfaces, and patching.
Compare against itemized plumber bids, permits, and code requirements.
Ask whether drywall cutting, patching, painting, tile repair, permit fees, and shutoff valves are included.
A repipe estimate should separate supply piping from drain lines, sewer work, fixture replacement, and water heater upgrades.

Many whole-house repiping projects fall between $4,000 and $20,000+, but copper, multi-story homes, difficult access, permits, wall repair, and fixture upgrades can push costs higher.
Usually yes. PEX often has lower material and labor costs than copper, but the final quote still depends on local code, plumber preference, fittings, access, warranty, and restoration.
Not always. Ask whether the plumber includes cutting, patching, texture, paint, tile, cleanup, permits, and fixture reconnection, or whether those are separate trades.
Yes. Compare pipe material, fixture count, access assumptions, permit responsibility, wall repair, warranty, timeline, and whether the bid covers supply lines only or additional plumbing work.
