Whole-Home Repiping & PEX Replacement in Mesa, AZ
Replace failing copper, polybutylene, and galvanized pipes with Uponor PEX-A by licensed master plumbers
Plumbing supply systems have finite lifespans. In the East Valley, homes built prior to 1970 often have galvanized steel pipes that are severely choked with internal rust and mineral scale. Homes constructed from the late 1970s through 1990s frequently contain defective polybutylene (Quest) piping or soft copper lines that suffer from recurring pinhole leaks due to Arizona's aggressive water chemistry.
When spot repairs become an annual headache, a whole-home repipe is the smartest long-term investment you can make in your property. Plumbing Company Mesa specializes in whole-home repiping using industry-leading Uponor PEX-A expansion piping.
Our licensed and bonded licensed master plumbers execute repiping projects with surgical precision, keeping wall openings minimal and ensuring your household has running water at the end of every work day.

1980s Polybutylene Whole-Home Repipe
A homeowner suffered two polybutylene fitting bursts within 6 months, causing insurance cancellation threats and constant anxiety over water damage.
Our 2-man crew repiped the entire 2,200 sq ft, 2.5-bath home with Uponor PEX-A expansion tubing, installed new brass quarter-turn stops, and replaced the main PRV.
"Jesse and Raul were extraordinarily clean and professional. Our water pressure is better than it has ever been and we finally have peace of mind."
Why Uponor PEX-A Is the Superior Material for Arizona
Copper is rigid and vulnerable to the corrosive minerals found in Mesa's hard water. Uponor PEX-A (cross-linked polyethylene) is flexible, highly durable, and chemically inert, making it completely immune to scale buildup and pitting.
PEX-A uses shape-memory ProPEX expansion fittings that actually grow tighter over time, eliminating rubber O-rings and crimp rings that can leak. It also dampens water hammer noise and expands without splitting if temperatures drop.
Our Surgical, Clean Repiping Process
Many homeowners delay repiping because they fear their home will be torn apart. We use a surgical process: laying down protective drop cloths, masking work zones, and making small, precise drywall access cuts.
Our crew typically completes a full single-family repipe in 2 to 3 days, and we always restore water service by the end of every workday so your family remains comfortable at home.
Mesa Homeowner Maintenance Tips
- Ensure your home's Pressure Reducing Valve (PRV) maintains water pressure between 55 and 70 PSI
- Pair your new PEX plumbing with a whole-home water softener to protect luxury fixtures
- Familiarize all household members with the location of the new main quarter-turn shutoff valve
- Operate fixture angle stops once a year to ensure smooth, unhindered operation
Repiping & Pipe Repair Frequently Asked Questions
How long does a whole-home repipe take, and will I be without water?+
Most residential repiping projects take between 2 to 4 days, depending on home size and number of bathrooms. Crucially, your water is only turned off during active working hours—we always reconnect and test your water system so you have full domestic water every evening.
Why is Uponor PEX-A better than copper in Arizona?+
Arizona's municipal water has high total dissolved solids (TDS) and mineral hardness, which corrodes copper pipes and causes pinhole leaks. PEX-A is flexible, completely immune to mineral corrosion, expands without bursting in sudden freezes, and carries a 25-year manufacturer warranty.
Will a whole-home repipe improve my water pressure?+
Yes, significantly. If your home has old galvanized steel pipes with heavy internal rust constriction, repiping with smooth-interior PEX-A restores original design volume and balanced water pressure across all fixtures.
Do you handle city building permits for repiping?+
Yes. Plumbing Company Mesa is a fully licensed and insured contractor. We file all required municipal permits with the City of Mesa or your local jurisdiction and coordinate the final building inspector sign-off.
