Replumbing a house with PEX typically costs $4,000-$15,000, with many standard whole-house projects averaging about $8,000. Home size, pipe access, fixture count, local labor rates, and wall repairs have the biggest effect on the estimate.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house PEX repipe | $4,000 | $8,000 | $15,000 | Typical 1-2 bathroom house |
| Large or difficult repipe | $12,000 | $18,000 | $25,000+ | More fixtures, multiple stories, or difficult access |
| Installed PEX piping | $4 per sq. ft. | $7 per sq. ft. | $10+ per sq. ft. | Broad planning estimate; scope varies |
| Single fixture branch | $300 | $700 | $1,500 | Depends on distance and wall access |
PEX repipe prices for common house sizes
A small home with one bathroom may cost $4,000-$7,000 to repipe, while a 1,500-2,000-square-foot home with two bathrooms often falls around $6,000-$12,000. Larger homes with three or more bathrooms can reach $12,000-$25,000 or more when long pipe runs, extra fixtures, or challenging access add work.
A practical average for a standard whole-house PEX repipe is about $8,000. That estimate assumes standard PEX tubing, ordinary access, and replacement of supply lines rather than drain and sewer piping. Costs are often higher in expensive metro areas and lower in lower-wage markets. Assumptions: U.S. home with standard fixtures, typical materials, and no major structural repairs.
Where PEX tubing, labor, and permits appear on the quote
A plumber’s quote may combine materials and labor into one total, so buyers can request an itemized estimate. The cost split below is illustrative for a $8,000 project, not a fixed national breakdown.
| Quote item | Typical range | Example on $8,000 job | What it covers |
|---|---|---|---|
| PEX, fittings, and valves | $800-$2,000 | $1,400 | Tubing, manifolds, connectors, shutoffs |
| Plumbing labor | $3,500-$8,000 | $5,000 | Routing, connections, testing |
| Equipment and setup | $150-$600 | $300 | Tools, protection, work-area setup |
| Permits and inspection | $100-$500 | $250 | Local approval and required inspection |
| Removal and disposal | $200-$1,000 | $500 | Old pipe removal and debris handling |
| Wall patching allowance | $300-$2,000 | $550 | Basic close-up; painting may be extra |
Labor and access usually outweigh the price of the PEX itself. Plumbing labor commonly runs $75-$150 per hour, though a repipe is often quoted as a project price.
How floor area and pipe access change PEX labor rates
Square footage helps estimate the amount of piping, but bathroom count and layout often predict labor better. A 1,200-square-foot home with three bathrooms may need more branches than a larger home with one bathroom. Each added kitchen, laundry connection, outdoor spigot, or shower can increase labor and fitting needs.
Access is a major price driver. Open basements or crawl spaces can reduce cutting and routing time; finished walls, tile, slab foundations, and tight crawl spaces can add hundreds or several thousand dollars. A two-story layout may require longer vertical runs and more openings than a single-story home.
Ask whether the quote includes wall openings, pressure testing, and patching. PEX tubing may be routed through accessible cavities, but the exact path depends on framing, local code, and the plumber’s installation plan.
Can a partial PEX repipe cost less than replacing every line?
A partial repipe can make sense when a leak or corrosion problem is limited to one branch or area. Replacing a kitchen or bathroom supply run may cost roughly $500-$2,500, depending on access and distance. A single fixture connection can be less, but a service minimum or diagnostic charge may apply.
Whole-house replacement is more likely to be economical when several lines are failing, old piping is widespread, or repeated repairs are accumulating. A partial job may also require connecting new PEX to existing copper or other pipe, which can add transition fittings and leave older sections in service.
Compare the partial repair quote with a full-repipe quote before deciding. The lowest immediate price may not address other aging lines, while a full replacement may be unnecessary if the issue is isolated and the remaining piping is sound.
What three PEX repipe quotes look like
These examples show how home size and access change a quote. Prices assume standard PEX materials and exclude premium finish restoration.
| Project | Scope and labor | Estimated total |
|---|---|---|
| Compact ranch | 1,000 sq. ft., 1 bathroom, accessible crawl space, 30-40 labor hours | $4,500-$7,000 |
| Typical two-story home | 1,800 sq. ft., 2 bathrooms, moderate wall access, 45-65 labor hours | $7,500-$12,500 |
| Large house with difficult access | 2,800 sq. ft., 3 bathrooms, finished ceilings, 70-100 labor hours | $14,000-$23,000 |
These totals are planning ranges, not guaranteed bids. Local rates, fixture count, required pipe route, and whether patching is included can move the final price substantially.
How many days does a PEX crew need?
A straightforward repipe may take one to three working days; a larger or difficult project can take four to seven days. Crew size is often two or three plumbers, with work sometimes split between opening access, installing pipe, testing, and restoring water service.
Ask how long the home will have limited or interrupted water, whether the crew will work room by room, and whether the price includes cleanup. A tight deadline, weekend work, or emergency scheduling may carry a premium, particularly during periods of high contractor demand.
Confirm the schedule and water shutoff plan in writing. Temporary water arrangements and additional visits can affect both convenience and labor charges.
Which permits and wall repairs add to PEX repiping bills?
Permit requirements vary by city and county. When required, plumbing permits and inspections commonly add about $100-$500, but local fees or required upgrades can raise that amount. Some jurisdictions require specific materials, approved connection methods, or inspection before walls are closed.
Opening and patching walls is a separate budget concern. Basic drywall repair may cost $300-$1,000 across a modest project; extensive texture matching, tile work, cabinetry removal, or repainting can cost more. Clarify whether the plumber handles only plumbing openings or also finishes the surfaces.
Check permit responsibility and restoration limits before approving work. A low plumbing bid may exclude permits, drywall, paint, or repairs to damaged finishes.
Reduce PEX replumbing price through scope and finish choices
Request at least three itemized quotes using the same fixture list and project scope. Compare tubing type, fitting system, shutoff replacement, testing, permit fees, disposal, wall openings, and warranty terms rather than choosing by total alone. Quotes that omit restoration or permits may look cheaper but leave costs for later.
Keep the work focused on necessary supply lines, choose standard PEX rather than optional premium features unless they solve a specific need, and clear access to plumbing areas before the crew arrives. Bundling related plumbing work during the same visit may reduce repeated setup charges, but unrelated upgrades should be priced separately.
Scope clarity is the most reliable way to prevent surprise charges. Have the plumber identify what remains in place, what gets replaced, and how concealed damage or code issues will be priced if discovered.
