Whole-Home Repiping

Some North Valley homes still carry their original copper, eaten thin by years of hard water. And 1970s-80s properties, common in Sun City and older Glendale, may have failure-prone polybutylene or galvanized pipe. We repipe whole homes in PEX, usually in a day or two, with minimal drywall opening and a clear restoration plan so you know exactly what comes next. Done right the first time.

Same-day on most calls. Upfront pricing before any work.

What it costs: Quoted by the house: number of fixtures, one storey or two, slab or crawlspace, and PEX or copper. Fixed price in writing before we open a wall, including the drywall patching. See typical whole-home repiping pricing.

Signs you need whole-home repiping

  • Repeated pinhole or slab leaks in aging copper
  • Polybutylene (gray) or galvanized (silver, corroding) supply pipe
  • Discolored water or low pressure at multiple fixtures

How we handle it

  1. Map the runs

    We plan the PEX routes to minimize wall openings and keep the job to a day or two.

  2. Repipe & pressure-test

    New manifold and lines, fully pressure-tested before we close anything up.

  3. Patch & restore

    Drywall patched and textured so it's not a months-long project.

What to know about whole-home repiping in Arizona

A whole-home repipe replaces all the water supply lines in a house, just the supply side, not the drains. It's the permanent answer once a plumbing system has worn out its material life. The signs add up over time: recurring pinhole leaks, repeated slab leaks, discolored or metallic-tasting water, pressure that keeps dropping as lines scale shut, and the plain math that you're spending more on repairs every year. At some point chasing one leak at a time costs more than ending the problem for good, and an honest plumber will tell you when you've hit that line.

Material choice is the real decision in a repipe, and the two mainstream options behave differently in Arizona. PEX is flexible cross-linked tubing. It's freeze-tolerant (it expands rather than bursting), it shrugs off the scale and pinhole corrosion that kill copper here, it goes in faster with fewer joints, and it costs less. That's why it dominates Arizona repipes. Copper is rigid, time-proven, and recyclable, but it's the very material that pinholes in our water and soil. For most metro Phoenix homes, PEX directly solves the failure that triggered the repipe.

High-country homes change the calculus. In Flagstaff and Prescott, freeze resistance moves to the top of the priority list, and PEX's ability to expand when water freezes inside it, rather than splitting like copper, is a real advantage for cabins and homes with lines in unconditioned spaces. Run placement matters too. A smart repipe keeps lines out of exterior walls and unheated areas where it can, and the repipe is the one chance to fix decades-old routing mistakes that have been freezing or leaking the whole time.

A repipe is invasive but predictable, and knowing the process takes the fear out of it. New lines usually run through walls, ceilings, and attics to reach every fixture, which means cutting access holes in drywall. A good crew keeps those few and writes them down. It takes a permit and inspection in Arizona jurisdictions, the work usually wraps in a few days, and water's back on each night in most cases. The drywall patching and texture matching afterward is part of a complete job. Ask up front whether it's included, because a 'repipe' that leaves you with twenty open holes isn't finished.

Whole-Home Repiping, frequently asked

Why PEX over copper?
PEX shrugs off the scale and corrosion that kills copper in our hard water. It installs faster, and it costs less.
How disruptive is it?
Most homes are back to full water service the same day, with drywall patching to follow. We stage it room by room.
How do I know it's time to repipe instead of repairing?
When you're getting pinhole or slab leaks again and again, seeing discolored water, losing pressure as the lines scale shut, and spending more on repairs every year, you've hit the point where one repipe costs less than the endless leak chasing it replaces.
PEX or copper for an Arizona repipe?
PEX wins out here because it shrugs off the scale and pinhole corrosion that kill copper in our hard water and rough soil, it handles a freeze by expanding instead of bursting, and it goes in with fewer joints. Copper is proven, sure, but it's the exact material that keeps failing in our water.
How long does a whole-home repipe take and will I have water?
Most homes repipe in a few days, and we'll usually have water back on each evening so you're not without it overnight. The job needs a permit and inspection, and we'll cut drywall access holes to run the new lines.
Does a repipe include fixing the drywall holes?
It should. Running new lines means cutting access holes, and patching plus matching the texture is part of a complete job. Always confirm up front whether drywall repair is included, so you're not left staring at open holes after the plumbing passes inspection.
Is PEX a better choice for a Flagstaff or Prescott cabin?
Yes. PEX can expand when water freezes inside it instead of splitting like rigid copper, and that's a real advantage in homes and cabins with lines in unheated spaces. A repipe is also your chance to reroute pipes out of cold exterior walls.
