A PEX plumbing cost estimator puts a typical whole-house repipe at about $2,000-$8,000, with many standard projects averaging $5,000. Home size, pipe access, fixture count, local labor rates, and whether walls need repair make the largest difference to the final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house PEX repipe | $2,000 | $5,000 | $8,000 | Typical home, standard access |
| Partial repipe or repair | $300 | $1,000 | $2,500 | Limited lines or one area |
| Installed PEX pipe | $2 per linear ft | $4 per linear ft | $8 per linear ft | Labor and materials; access affects rate |
| Fixture connection | $150 | $400 | $800 | Per fixture, depending on rerouting |
What a whole-house PEX repipe usually costs
For a 1,500-2,000-square-foot house with roughly 8-12 plumbing fixtures, a standard PEX repipe commonly costs $3,500-$6,500. Smaller homes with exposed basement or crawl-space lines may land near $2,000-$3,500; larger homes, difficult access, or extensive rerouting can reach $8,000-$12,000 or more.
A practical planning figure is about $5,000 for a straightforward, mid-size home repipe. Estimates generally assume contractor-supplied PEX, standard fittings and shutoff valves, ordinary access, and no major finish restoration. Regional labor costs and the amount of pipe replaced can move the total considerably.
For a rough materials-and-labor estimate, multiply the expected pipe run by about $2-$8 per linear foot, then add fixture connections, manifold or valve work, permits if required, and wall or ceiling repairs. A plumber must confirm pipe routes and fixture counts before that calculation becomes a reliable quote.
How pipe, labor, fittings, and wall repairs add up
Contractor quotes may group several tasks together, so asking for a line-item estimate makes comparisons easier. These ranges describe common contributions to a typical repipe, not guaranteed charges; components may overlap in a bundled quote.
| Quote component | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| PEX tubing and fittings | $300-$1,200 | About $0.50-$2 per pipe ft for materials | Pipe diameter, fitting count, manifold design |
| Plumber labor | $1,500-$5,000 | $75-$150 per hour | Crew size, access, rerouting time |
| Valves and manifold | $200-$900 | Per system | Number of branches and shutoffs |
| Permits and inspection | $50-$500 | Per project | City or county requirements |
| Opening and patching surfaces | $300-$2,000 | Per project | Wall material, finish, number of access holes |
Labor is often the largest variable, particularly when pipes run through finished walls instead of open basements, attics, or crawl spaces. Painting, tile replacement, and premium fixture upgrades may be excluded from a plumbing quote.
Pipe length, fixture count, and access change the estimate
Three details can sharpen an early estimate: the approximate pipe route, number of fixtures, and ease of reaching the existing lines. A one-bathroom home with 6-8 fixtures may need fewer branches than a two- or three-bathroom house with 10-15 fixtures. Each added fixture or distant branch can increase labor, fittings, and pipe use.
Pipe size and routing matter too. Common residential branches use 1/2-inch PEX, while main supply sections may use 3/4-inch or larger pipe. A long route of more than 100 linear feet, multiple floors, or concrete-slab work can push a quote above a simple per-foot estimate. Slab penetrations and concealed leaks may require separate repair work.
Access can outweigh the tubing price. Exposed lines in a basement or crawl space usually cost less to replace than lines behind finished drywall, plaster, or tile. Ask whether the estimate includes opening surfaces, patching, and cleanup; plumbing and finish-repair charges are often separate.
Regional labor rates shift PEX installation prices
Labor rates vary by market. As a broad comparison, an otherwise similar repipe may cost about 10%-25% less in a lower-cost rural market than the national midpoint, while major metro areas in the Northeast, West Coast, or Hawaii may run 15%-35% higher. These are planning adjustments, not fixed regional tariffs; local access, contractor availability, and permit rules still matter.
For example, a $5,000 baseline could translate to roughly $3,750-$4,500 in a lower-cost area or $5,750-$6,750 in a high-cost metro before unusual repairs. Compare written bids from local licensed plumbers using the same fixture count, pipe scope, and restoration assumptions.
How long plumbers need for a typical house repipe
A small, accessible repipe may take one plumber and an assistant about 1-2 days; a larger or harder-to-access house can require a crew of 2-4 for 2-4 days. Water may be shut off for part of the work, and inspection or finish repairs can extend the full project schedule.
At $75-$150 per labor hour, a two-person crew working 16-32 combined crew hours represents roughly $1,200-$4,800 in labor before materials and other charges. The hourly figure is a useful comparison point, but many plumbers price repipes as a fixed project rather than billing every hour separately.
Three sample PEX quotes for different home sizes
These examples use typical U.S. pricing and illustrate how size and access affect an estimate. The figures assume standard PEX materials, ordinary fixtures, and no major structural or finish restoration.
| Scenario | Scope and labor | Estimated total |
|---|---|---|
| Small, accessible home | 900 sq ft, 6 fixtures, about 80 ft of pipe, 12-16 crew hours | $2,500-$4,000 |
| Mid-size two-bath home | 1,700 sq ft, 10 fixtures, about 140 ft of pipe, 20-28 crew hours | $4,000-$7,000 |
| Large, difficult-access home | 2,600 sq ft, 15 fixtures, about 220 ft of pipe, 32-48 crew hours | $7,000-$12,000 |
Pipe footage is approximate because routing varies by floor plan. A quote outside these ranges can still be reasonable when it includes extensive wall access, slab work, upgraded shutoffs, or higher local labor rates.
When a repair costs less than replacing every line
A localized PEX repair may cost about $300-$1,000 when the leak is accessible and only a short pipe section or fitting needs replacement. Multiple leaks, brittle or corroded existing supply lines, or repeated repair visits can make a full repipe more economical over time. Ask the plumber to price both a targeted repair and a complete replacement if the system has recurring problems.
PEX is flexible and can reduce the number of fittings, but an alternative such as copper may cost more because of material prices and installation labor. The right comparison depends on local code, water conditions, routing, and the contractor’s warranty. Avoid choosing by pipe price alone; include installation and future access in the comparison.
Ways to lower the PEX plumbing quote without cutting corners
Keep the scope precise by listing which lines, fixtures, and shutoffs need replacement. Replacing only accessible problem areas can reduce immediate spending, while bundling planned plumbing work may avoid paying for another mobilization later. Do not pay to replace sound lines unless the plumber explains why the added scope is justified.
Clear stored items from the basement, crawl space, or work area before the crew arrives, and obtain separate prices for plumbing and finish restoration. Request at least two itemized bids that state pipe type and diameter, fixture count, permit responsibility, cleanup, warranty, and exclusions. Matching the scope—not just the bottom-line total—is the best way to identify a genuinely lower-cost quote.
