A whole-house PEX-A repipe runs about $5,594 to $11,229 at researched defaults, scaling with fixture count: roughly 8 fixtures at the low end and 18 at the high end, over galvanized pipe in a crawl-space home at $135 an hour of labor. The scenarios below show the parametric math, fixture by fixture, from a real plumbing pack.

Real resolver output from the plumbing pack’s researched defaults. The permit is a pass-through billed at cost — never marked up (Law 3); the flagged rows are what low quotes leave off.
A single “ballpark” hides where the money goes. Priced line by line, you can see the equipment, the labor, the code add-ons, and the pass-throughs separately — and check any quote you get against them. That’s the whole point of this tool.
The pack scales both materials ($220 + $95 per fixture) and labor (4.0 hr + 2.2 hr each tech, per fixture). Every sink, tub, toilet, and hose bib counts.
Slab, crawl, or basement changes how the new lines are run — access drives the labor.
Galvanized, copper, or poly-B changes demo effort and what has to come out of the walls.
Replacing every angle stop and adding new hose bibs are real add-ons — worth doing while the walls are open.
A cheap quote usually gets cheap by leaving something out. These are the same items the app’s review engine flags for a contractor — inverted here, so a homeowner can spot them too.
This calculator prices PEX-A, the common modern choice: faster to run, freeze-tolerant, and cheaper in labor. Copper costs more in both material and time. A contractor can quote either; the fixture-count math is what drives the total.
Usually water is off during working hours and restored each night. A whole-house PEX repipe is often one to a few days depending on fixture count and foundation access — the same two factors that move this price.
It depends on why. Isolated galvanized failures can be partial; systemic corrosion or poly-B usually means whole-house. This tool prices whole-house by fixture count; a partial job is a smaller version of the same math.
Often not — many plumbers quote the repipe and leave patching to you or a separate trade. Always ask. This calculator prices the plumbing work; it doesn't assume drywall or paint.
