Repiping
When the plumbing system fails as a whole, stop patching it
Galvanized steel in a 1960s or 1970s Valley home rusts from the inside until the pipe is a straw. Copper in a slab can pinhole from aggressive water. When leaks start appearing in different places, the system is telling you something.
Straight answer
How much does repiping cost in Phoenix, and how long does it take?
Whole house repiping in the Valley typically costs $6,000 to $15,000 depending on home size, fixture count, whether lines run through the attic or inside walls, and how much drywall repair is required. Permits are included in our written estimate.
Most single-family repipes take three to five working days and you can stay in the home. Water is off during working hours, bathrooms are restored each evening, and floors and furniture are protected daily. The disruption is real but planned, not chaotic.
What a repipe project includes
- System evaluation and pressure test that documents whether repiping is genuinely needed or a repair will do.
- Material choice priced both ways: copper or PEX, with joint counts, warranty terms and cost differences explained.
- Main line, branch lines and fixture stubs replaced as a coordinated set rather than in fragments over years.
- Shutoff valves and hose bibs renewed while the system is open, since those fail next.
- Drywall patching and texture as part of the scope, so you are not hunting for a second contractor afterwards.
- Permit, inspection and pressure test documentation emailed to you, with daily floor protection and evening water restoration.

Repair or repipe? The honest test
- Repair when there has been one leak, the line is copper under 40 years old, and pressure is still normal everywhere.
- Repipe when two or more leaks appear in a year, when water runs rusty after sitting overnight, or when galvanized steel is still in service.
- Repipe before selling if a home inspection is likely to flag the plumbing, since documented permits and a pressure test support the sale price.
- Spot reroute is a legitimate middle option for a single slab leak, and we price it alongside the full repipe so you can compare over five years.
We will not sell a repipe to a house that needs a valve, and we will say clearly when patching is throwing money at a system that is finished.

Typically $6,000 to $15,000 depending on square footage, fixture count, whether lines run in the attic or through walls, and the drywall repair involved. Estimates are itemized and include permits.
Repeated leaks in different spots, rusty water in the morning, a pressure drop when two fixtures run, or galvanized steel lines in a pre-1980 home. Two leaks in one year usually means the system is failing overall, not in one place.
Three to five working days for most single-family homes, and yes, you can stay. Water is off during working hours only, bathrooms are put back each evening, and floors and furniture are protected daily.
Both work well in the Valley. PEX costs less, has fewer joints and resists aggressive water chemistry; copper is traditional and fully recyclable. We price both and explain the warranties instead of steering you toward one.
