Whole-house repiping typically costs $4,000-$15,000, with many homeowners paying about $8,000 for a standard-size home. The repiping cost depends mainly on home size, pipe material, access to existing lines, fixture count, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house repipe | $4,000 | $8,000 | $15,000 | Typical 1,500-2,500-sq-ft home |
| PEX pipe installation | $4,000 | $7,000 | $12,000 | Often the lower-cost material |
| Copper pipe installation | $8,000 | $13,000 | $20,000 | Higher material and labor expense |
| Localized repipe | $1,500 | $3,500 | $6,000 | Limited rooms or branch lines |
Whole-house repiping prices by home size
A smaller, single-story home with accessible plumbing may cost $4,000-$7,000 to repipe with PEX. A 1,500-2,500-sq-ft home commonly falls near $6,000-$12,000, while a larger or multi-story property can reach $12,000-$20,000 or more. Copper generally pushes estimates toward the upper end.
Installed pricing is often estimated around $4-$10 per linear foot for PEX and $8-$15 per linear foot for copper, though contractors may quote by project rather than measured pipe length. Fixture count also matters: adding bathrooms or separate hot-water branches increases labor and fittings. Assumptions: standard residential layout, ordinary access, and no major structural repairs. For a typical home, about $8,000 is a reasonable starting budget, not a guaranteed quote.
What pipe, labor, and wall repair add to a quote
A repiping estimate includes more than the pipe itself. Labor, fittings, access work, permits, and patching can represent a substantial share of the total. The ranges below describe common project allowances; the categories can vary by contractor and may overlap in a bundled quote.
| Quote item | Typical range | Pricing basis | What changes the charge |
|---|---|---|---|
| PEX or copper pipe and fittings | $800-$5,000 | About $4-$15 per linear ft installed | Material, length, and branch count |
| Plumber labor | $2,000-$8,000 | $75-$150 per hour | Crew size, access, and job duration |
| Equipment and access | $300-$1,500 | Per project | Drilling, crawlspace, or slab conditions |
| Permits and inspection | $100-$800 | Per project | Local requirements and scope |
| Drywall patching and disposal | $500-$3,000 | Per project | Number and size of openings |
Plumbing labor may be estimated as . Ask whether drywall repair, painting, fixture reconnection, and cleanup are included; plumbing contractors may exclude finish work. A written, itemized quote makes it easier to compare the same scope across bids.
How pipe length and access change the estimate
Two houses with the same square footage can have different repiping prices because pipe routing and access vary. A compact, single-story layout may need fewer long runs than a multi-story house with bathrooms at opposite ends. Finished walls, tight crawlspaces, and pipes beneath a slab can add cutting, drilling, or rerouting work.
Scope thresholds matter. A 1-bath home with roughly 6-10 fixtures may need fewer branches than a 3-bath home with 15 or more fixtures. A simple PEX reroute through an open attic or crawlspace may stay near the lower estimate; slab work or extensive wall openings can add $1,000-$5,000 or more. Ask the plumber to identify the assumed pipe route and count of fixtures in the estimate.
PEX versus copper for a complete home repipe
PEX is flexible and often requires less labor, making it a common budget choice at roughly $4,000-$12,000 for a typical whole-house project. Copper commonly costs $8,000-$20,000 because the material is more expensive and installation can take longer. Local code, water conditions, and contractor preference can affect availability and suitability.
For a house with 2,000 sq ft and two bathrooms, a straightforward PEX estimate might be $6,000-$9,000, compared with $10,000-$16,000 for copper. These are broad planning ranges, not a direct material-only comparison: access, fittings, permits, and finish repairs still affect both bids. Compare complete installed totals and warranty terms, not only the pipe price.
How long a plumber needs to replace home piping
A typical whole-house repipe takes about 1-3 days of plumbing work, often with a crew of two or more. Complex layouts, concrete access, or extensive rerouting can extend the job to several days. Water service may be interrupted during parts of the work, so the estimate should state when fixtures will be usable again.
Labor rates often range from $75-$150 per hour, with higher rates possible in expensive metro areas or for urgent work. Some firms price the project as a fixed bid instead of billing hourly. Confirm crew size, expected workdays, and whether temporary water service is included.
Regional labor rates and repiping totals
National ranges hide meaningful local differences. Estimates in high-cost coastal metros can run about 15%-30% above a typical national quote, while some rural and lower-cost regions may come in 10%-20% below it. These are planning adjustments rather than fixed regional prices; travel distance, contractor availability, and local permitting also matter.
For example, a $8,000 baseline PEX estimate might become roughly $9,200-$10,400 in a higher-cost market or $6,400-$7,200 in a lower-cost area, assuming the same scope. Compare at least two or three local bids with matching materials and repair allowances.
Can a targeted pipe repair avoid a full repipe?
A localized repair may cost $300-$1,500 for a simple accessible leak, while replacing a branch line or repiping one room can run $1,500-$6,000. A targeted fix can make sense when the pipe problem is isolated and the remaining system is in good condition. Repeated leaks, widespread corrosion, or failing galvanized steel may make a broader replacement less expensive over time.
Have the plumber distinguish the immediate repair from the condition of the rest of the system. A diagnostic visit may cost $75-$250, sometimes credited toward approved work. Ask for separate prices for the urgent repair and a full repipe before choosing a scope.
Permits, drywall, and fixture costs after repiping
Permit fees commonly range from $100-$800, depending on local rules and whether inspections are required. Drywall patching and painting may add $500-$3,000 when walls or ceilings need multiple openings; matching texture or repainting full rooms can raise that amount. Moving fixtures, upgrading shutoff valves, or replacing old faucets can also increase the bill.
Before work starts, confirm who obtains permits and whether inspection, debris removal, and patching are included. If finishing work is excluded, a separate drywall contractor may charge a minimum service fee even for a small repair. Budget separately for plumbing and finish restoration unless the quote clearly bundles both.
