Call About This ServiceWhy Choose Plumbing 405?
Here's what you get when you trust us with your whole house repiping project.
Eliminate Rust & Discolored Water
Old galvanized pipes corrode from the inside, leaching rust into your drinking water. New copper or PEX pipes deliver clean, clear water.
Restore Full Water Pressure
Mineral buildup and corrosion in aging pipes choke water flow. A full repipe restores full pressure to every shower, faucet, and appliance.
Stop Constant Leaks
Homes with aging pipes suffer repeated leaks. Instead of patching problems forever, a full repipe is the permanent, cost-effective solution.
Increase Home Value
Updated plumbing is a major selling point. A repiped home commands higher offers and passes home inspections with ease.
50+ Year Lifespan
Copper and PEX piping systems are built to last generations, giving you peace of mind for decades.
Lower Water Bills
Pinhole leaks and inefficient pipes waste thousands of gallons per year. Repiping stops hidden losses immediately.
