What We Do
What We Repipe & Why on O'ahu
Different pipe materials fail for different reasons — we know them all and handle every situation.
Corroded Copper Pipe Replacement
O'ahu's older homes often have copper pipes that have thinned from decades of use and Hawaii's mineral-rich water. Pinhole leaks are a sign the copper has failed. We replace the affected sections or the entire system.
Galvanized Pipe Replacement
Galvanized steel pipes from the 1950s–80s rust from the inside out, restricting flow and discoloring water. Full replacement restores water pressure and eliminates rust contamination.
PEX Repiping
PEX (cross-linked polyethylene) is the modern standard for water supply lines. It's flexible, corrosion-resistant, and easier to install with less drywall disruption than rigid pipe.
Polybutylene Pipe Replacement
Polybutylene (grey plastic pipe common in 1980s–90s homes) degrades and fails without warning. It should be proactively replaced before a major leak occurs.
Commercial Repiping
Multi-unit buildings, commercial properties, and hotels on O'ahu often have aging pipe systems that require full replacement. We handle large-scope commercial repiping projects.
Partial Repipe
Not every situation requires replacing the entire system. We assess your plumbing and recommend partial repiping when only specific sections have failed or are at risk.
