Replace aging, corroded, or failing pipes throughout your Portland home — comprehensive repiping in copper or PEX.
If your Portland home was built before 1985, there's a strong chance it still has original galvanized steel or outdated polybutylene pipes. These materials corrode from the inside out, causing discolored water, low pressure, pinhole leaks, and eventually major pipe failures.
PNW Plumbing LLC specializes in whole-home repiping throughout Portland, Oregon — replacing old piping systems entirely with modern copper or PEX piping that will last for decades. It's one of the best investments you can make in an older home.
If you recognize any of these, call PNW Plumbing at 503-957-8703.
Consistently brown, orange, or cloudy water from hot or cold taps is a sign of severely corroded pipes.
If you've had two or more pipe leaks in recent years, the entire system may be failing.
Gradual pressure loss across all fixtures indicates significant corrosion narrowing the inside of pipes.
Loose, corroded, or improperly supported pipes make noise as water flows through them.
Galvanized steel and polybutylene pipes from this era are near or past their reliable lifespan.
Buyers' inspectors flag old piping. Repiping before listing increases your home's value and avoids deal-killing inspection findings.

Both are excellent. Copper is the gold standard — durable, proven, and adds home value. PEX is flexible, excellent for retrofits, freeze-resistant, and faster to install. We'll recommend the best choice for your specific home.
You don't need to be present the entire time, but we ask that someone is home at the start and end of each day, and that you have a plan for water shut-off periods.
