Whole House Repiping & Reroutes in Rancho Cucamonga
When old pipes start failing, one repair follows another. We replace the whole system once, correctly, with a free estimate up front.
Whole house repiping means replacing every water supply line in your home, from the point where water enters at the main to each fixture. A reroute takes a different path: instead of chasing a leaking line buried under your slab, we run new pipe overhead through the attic or walls, abandoning the bad line entirely. Both solve the same problem. Your pipes have reached the end of their working life.
Rancho Cucamonga is hard on plumbing. Our water carries heavy mineral content that scales up pipe interiors year after year, and many homes here built before 1980 still have original galvanized steel lines. Galvanized pipe corrodes from the inside out. It narrows, rusts, and eventually pinholes. Homes on slab foundations add another risk: supply lines under the concrete that fail where you can't see them.
W.P. Plumbing is owner-operated by Billy, licensed, bonded, and insured. Whole house repiping is one of the services we offer free estimates on, and the price we quote is the price you pay. We treat every home like our own, we don't cut corners behind your drywall, and the workmanship is guaranteed.

Why Homeowners Choose W.P. Plumbing
One Fix Instead of Ten
Patching a failing system means paying for the same problem over and over. New copper or PEX throughout ends the leak-repair-leak cycle for good.
Real Water Pressure Again
Corroded galvanized pipe can narrow to half its original diameter. New full-bore lines restore the pressure your showers and fixtures were designed for.
Clean, Safe Water
Rust flakes and mineral scale from old steel pipe end up in your glass and your water heater. New piping delivers clear water to every tap.
Honest Upfront Pricing
You get a free estimate on repiping projects, a firm price before work starts, and no surprise charges when the drywall goes back up.

Frequently Asked Questions
How long does a whole house repipe take in Rancho Cucamonga?
Most single-family homes take two to four days of pipe work, depending on size and how many bathrooms you have. Water stays on each evening, so you're not living without plumbing. Drywall patching adds a little time at the end. We give you a clear schedule with your free estimate before anything starts.
Should I repipe with copper or PEX?
Both are good choices, and we install both. Copper is rigid, proven, and handles heat well. PEX is flexible, resists scale buildup from our hard local water, and needs fewer fittings inside walls. The right pick depends on your home's layout and budget. Billy will walk you through the tradeoffs during the estimate, not push one answer.
Can you reroute around a slab leak instead of breaking the concrete?
Yes, and it's often the better option. Instead of jackhammering the foundation to reach one failed line, we run a new line overhead through the attic and abandon the old one under the slab. No torn-up flooring, less mess, and the new pipe is accessible if it ever needs service. We also do slab leak detection to confirm the problem first.
How much does whole house repiping cost?
It depends on the size of the home, the number of fixtures, and the pipe material you choose, so we don't quote blind numbers over the phone. What we do promise: the estimate is free, the price is upfront, and there are no surprise charges at the end. Call (909) 727-2959 and we'll take a look.
