How much does it cost to repipe a house?

Repiping an entire home typically runs $2,000–$15,000, with most homeowners spending around $7,500. By square footage, that works out to roughly $1–$8 per sq ft — PEX pipe lands at the low end, copper at the high end, with the number of fixtures and how hard the pipes are to reach moving it in between.

PEX vs. copper — which costs less to repipe with?

PEX costs meaningfully less than copper, both for the pipe itself (roughly $0.40–$2 per linear foot vs. $2–$8 for copper) and for labor, since it's flexible enough to snake through existing walls without opening them up as much. Copper lasts longer and resists bacteria and UV better, but most residential repipes today use PEX because the price gap is significant on a whole-house job.

Why is labor most of the repiping cost, not the pipe itself?

Labor typically runs about 70% of a repiping bill. The material — a few hundred to a couple thousand dollars in pipe — is a small piece next to the time it takes to access pipes behind walls, under floors, or in a slab, run the new lines, pressure-test the system, and patch up whatever had to be opened.

Do I need a permit to repipe a house?

In most areas, yes — a whole-house repipe changes plumbing that inspectors need to verify, and permits typically run $50–$500 depending on your city. A licensed plumber usually pulls the permit as part of the job and schedules the required inspection.

How do I know if my house needs to be repiped?

Watch for discolored or rusty water, a noticeable drop in water pressure, recurring leaks you keep patching, or pipe older than 50 years — especially galvanized steel, lead, or polybutylene, none of which are considered safe or worth repairing long-term. A plumber can inspect the accessible pipe to confirm before you commit to a full repipe.

How we localized this

We start from our national whole-house repipe range of $2,000–$15,000 and adjust it for Phoenix, where costs run about the same as the national average. Evidence on Phoenix's cost level is mixed: construction-cost indices and some remodeling guides put it modestly below the U.S. average, while broader cost-of-living measures run a few percent above (driven mainly by housing). We treat Phoenix as about the national average for home-improvement work pending cleaner local data. Phoenix costs have also been rising faster than the national rate recently — but that's growth, not level. Materials are priced roughly nationally, so treat this as an approximation — your actual price depends on your home, contractor, and project specifics.

Phoenix sits close to the national average for home-improvement costs — construction-cost indices place it a touch below, while broader living costs run a touch above. The desert climate is the bigger story: extreme summer heat makes HVAC the marquee trade here, so air conditioners work hard and get replaced often, and it pushes roofing and exterior work toward the cooler months. Permitting is generally straightforward across most of the Valley.

What changes the price

Home size — Raises cost
More square footage means more fixtures and longer pipe runs — repiping is priced mainly by the size of the home.
Pipe material — Varies
PEX is the least expensive and most common choice today; CPVC costs a bit more, and copper runs several times more for the same job.
Accessibility — Raises cost
Pipes reachable through a crawlspace or basement are far cheaper to replace than pipes under a concrete slab, behind finished walls, or on upper floors.
Number of fixtures — Raises cost
Each sink, toilet, shower, and appliance connection adds its own run and labor time.
Drywall & wall repair — Raises cost
Opening walls or floors to reach old pipes means patching them afterward, often billed separately from the plumbing work itself.
Permits & inspection — Raises cost
Most jurisdictions require a permit and inspection for a whole-house repipe, built into a licensed plumber's quote.

National range and per-sq-ft unit synthesize Angi, HomeGuide, and HomeAdvisor into one low–typical–high band rather than reproducing any single source's table. HomeAdvisor's own headline 'Normal Range' widget on this article ($372–$2,119, avg $1,246) directly contradicts its own per-square-foot body table on the same page (~$4.50/sq ft, i.e. $9,000+ for a 2,000 sq ft home) — read as a template/data mismatch on their end and NOT used; their per-square-foot table was used instead. Labor (~70% of the bill per both Angi and HomeAdvisor) is the dominant cost driver, not the pipe material. Metro-level breakdowns are coming as we verify local data.
