Repiping
Whole-home copper and PEX repipes, done in days
Galvanized steel and early polybutylene were never meant to last this long, and most of the San Gabriel Valley's housing stock is well past their date. Once a line rusts shut you get brown water, pressure that drops the moment a second tap opens, and pinhole leaks that keep coming back in new places. Advantage Build and Design replaces the whole system — copper or PEX — rather than chasing one failure at a time.
Our Process
Water Test & Walk
We check pressure, water quality, and pipe material, then map every run in the house.
Written Scope
You get a flat quote listing material, fixtures affected, permits, and how long you'll be without water.
Repipe & Pressure Test
New lines are run, tied in, pressure-tested, and inspected before anything is closed up.
Patch & Clean
Access holes are patched and textured, the site is cleaned, and we walk the job with you.
