Whole-home repipe cost in LA in 2026
When to repipe, what copper vs. PEX really costs, and how to recognize the signs your galvanized pipes are about to fail.
Many LA homes built before 1970 still have original galvanized steel pipes. They corrode from the inside out — pressure drops, water turns rusty, and pinhole leaks start appearing in walls.
Whole-home repipe range: $4,500 – $15,000
Drivers: home size (sqft), number of fixtures, accessibility, and pipe material (copper vs. PEX).
Copper vs. PEX
Copper lasts longer, costs more, and looks classic. PEX is flexible, faster to install, and freeze-resistant. Both are excellent — your pro will recommend based on your home.
