Water line repair & repiping — clean, reliable water from the street to every tap.
The pipe that brings fresh water into your home is easy to ignore — until pressure drops, the water turns rusty, or a leak shows up in the yard or under the slab. We repair and replace main water lines and re-pipe whole homes, with materials built for Sonoma County’s water.

Water line questions, answered
Why is my water pressure low everywhere?
Often a corroded or restricted main line, or a failing pressure regulator. We diagnose which before recommending a fix.
My water looks rusty — is that the pipe?
Usually yes — old galvanized pipe corroding from the inside. A repipe restores clean, clear water.
What is repiping, and how disruptive is it?
Replacing the old pipe throughout the home with new. We work cleanly and in stages — most homes stay livable throughout.
Can you replace the line under my driveway without tearing it up?
Often yes — using trenchless boring, we can run a new line with little or no digging across your hardscape.
Low pressure, rusty water, or a leak in the line? Let’s fix it.
