PEX pipe replacement typically costs $4,000-$12,000 for a whole-home repipe, with smaller repairs or partial replacements often running $500-$3,000. The final price depends on home size, access to existing pipes, fixture count, local labor rates, and whether wall or ceiling repairs are included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-home PEX repipe | $4,000 | $8,000 | $18,000 | Typical single-family home; difficult access raises cost |
| Partial replacement | $500 | $1,500 | $3,000 | One room, branch, or accessible pipe run |
| PEX pipe material | $0.50 | $1.25 | $2.50 per linear ft | Pipe grade and diameter affect price |
| Plumber labor | $75 | $110 | $175 per hour | Rates vary by region and job complexity |
What a whole-home PEX repipe usually costs
A standard 1,500-2,000-square-foot home with 1-2 bathrooms often costs $5,000-$10,000 to repipe with PEX. Smaller homes with open basements may come in near $4,000, while larger homes, multiple stories, or extensive access work can reach $12,000-$18,000.
Typical installed pricing is about $2-$6 per square foot of home area. That estimate generally covers new hot- and cold-water lines, connections to existing fixtures, and basic testing. It may exclude drywall repair, painting, new fixtures, and permit fees.
Assumptions: U.S. suburban labor rates, standard PEX-A or PEX-B, ordinary fixture count, and no major structural repairs.
How pipe, labor, and access shape the quote
A repipe quote combines pipe and fittings with the plumber’s time, access work, and reconnection of fixtures. Request an itemized estimate so the cost of pipe installation can be distinguished from wall patching or other work.
| Quote component | Typical range | Price basis | What changes it |
|---|---|---|---|
| PEX pipe and fittings | $500-$1,800 | $0.50-$2.50 per linear ft | Pipe grade, diameter, and run length |
| Plumbing labor | $2,500-$8,000 | $75-$175 per hour | Fixture count, access, and crew size |
| Access and removal | $300-$2,000 | Per project | Cutting openings or removing old pipe |
| Permits and inspection | $50-$500 | Per permit | Local rules and project scope |
| Drywall repair | $300-$2,500 | Per project | Number and size of openings |
Labor and access usually account for more of the bill than the PEX tubing itself. The labor component can be estimated with ; a 30-50-hour job at $100-$150 per hour implies $3,000-$7,500 before materials and additional trades.
How home size and pipe access change PEX pricing
Square footage is only a rough guide: a 1,200-square-foot home with two bathrooms may need more branches than a larger home with a simple layout. Quotes commonly rise as fixture count grows from 8-10 connections to 15 or more, because each fixture needs a hot- and cold-water connection.
Access is another major variable. A basement or open crawlspace can keep installation near the lower end; finished walls, slab foundations, and tight crawlspaces can add $1,000-$5,000 for labor and opening surfaces. A 2-story layout may also require longer vertical runs and more cutting.
Ask whether the bid includes every fixture and all concealed pipe runs. PEX diameters are often 1/2 inch for branch lines and 3/4 inch for larger supply runs; unusually long runs or high-demand fixtures may require larger pipe or additional design work.
How many plumber hours does a PEX repipe take
A straightforward 1-bathroom repipe may take 1-2 working days, while a 2-3-bathroom home commonly needs 2-4 days. A crew may include two plumbers, and water service can be interrupted during portions of the work. Wall repair and inspection can extend the total project schedule beyond the plumbing installation.
Labor often ranges from about 25-60 hours of combined crew time. Confirm whether the estimate uses a fixed project price or hourly billing, and ask how extra time is approved if hidden damage or blocked access is found.
Regional labor rates shift the installed PEX price
In lower-cost rural and smaller-market areas, a comparable repipe may price 10%-20% below the national midpoint. Large metropolitan areas and regions with high contractor demand can run 15%-30% higher, particularly when permits, parking, or difficult access add time.
Compare local bids using the same fixture count and included work. Two quotes can differ because one covers drywall repair or permits and the other leaves those expenses to the homeowner, not because the plumbing scope is equivalent.
When removal, permits, and repairs add to the bill
Removing old galvanized or copper pipe may add $300-$2,000, depending on how much is accessible and whether disposal is included. Permit and inspection charges commonly fall between $50 and $500, but local requirements vary. Emergency scheduling, water-damage cleanup, or work around a slab can create additional charges.
Separate plumbing from finish repairs when comparing estimates. Basic patching may be included, but matching texture, painting, tile replacement, and cabinetry work often are not. Ask for a written allowance or separate price for each excluded task.
PEX repair or full replacement for aging pipes
Replacing a short, accessible damaged line may cost $300-$1,200, while a larger partial repipe often costs $1,000-$3,000. These options can be economical when the rest of the system is sound. Repeated leaks, widespread corrosion, or multiple failing branches can make a full repipe more practical than paying for recurring repairs.
Compare the repair total with the cost of replacing all affected lines. A plumber should identify the pipe material, leak locations, and whether the issue is isolated; an estimate based only on one visible leak may miss concealed deterioration.
Ways to lower a PEX replacement estimate
Keep the scope clear by listing every bathroom, kitchen, laundry connection, and outdoor faucet that needs service. Where possible, schedule the work when access panels or unfinished areas are already open, and ask whether several plumbing tasks can be completed during the same visit.
Get at least three itemized quotes with matching specifications. Compare pipe type, line coverage, permits, testing, removal, and patching—not just the total. Avoid paying for fixture upgrades or premium pipe options unless the conditions or warranty terms provide a clear reason.
