What is whole-home repiping and when do you need it?
Whole-home repiping replaces the water supply pipes throughout a house, and Avanté Plumbing carries it out across Sonoma and Marin County under California CSLB licence #841938. It is the right call when the pipe material itself has failed rather than one joint: brown or rusty water when a tap is first opened, pressure that has dropped throughout the house, pinhole leaks arriving in clusters rather than one at a time, or visible corrosion on exposed runs. The usual culprit is galvanized steel, standard in homes built before the 1960s and still present in a great many North Bay properties — it corrodes closed from the inside, so the pipe narrows for years before it leaks. Mill Valley is a good example: roughly half its housing predates 1960. Repiping is disruptive but finite, and it ends the cycle of chasing one leak after another.

Common questions
Whole-Home Repiping FAQs
What types of pipes do you install?
We install top-grade materials including PEX and copper pipes. Our choice will depend on your home's specific needs and your preference.
Will repiping damage my walls or floors?
Our experienced team works to minimize disruption. We use advanced techniques to keep any cutting or removal to a minimum, ensuring a neat finish.
What do I need to do before you start the job?
It's best to have clear access to your plumbing systems. You may also want to clear areas around the intended work spaces. We'll provide a checklist before we start.
How do I know if my house needs repiping?
The classic pattern is galvanized steel supply piping, common in North Bay homes built before about 1970. It corrodes closed from the inside, so the symptoms are brown or rusty water especially after the house has sat, pressure that has fallen away at upstairs fixtures, and pinhole leaks that start arriving in clusters rather than singly. Repeated pinholes in different places is the signal that patching has stopped being economic.
How long does repiping a house take?
It varies with size, layout and access — a single-storey house on a crawlspace is a different job from a two-storey on a slab. The honest answer is that it is scoped after seeing the property, because the run routing and the amount of wall opening drive it more than the square footage does. We quote it after walking the house, not over the phone.
Do you need a permit to repipe a house?
Yes — repiping alters the plumbing system, so it is permitted work. Permit Sonoma records show permits for both water repiping and sewer drain repiping in unincorporated areas. In unincorporated Sonoma County the permit goes through Permit Sonoma, whose published schedule lists a $327 minimum trade permit fee plus small per-unit charges — $20.75 for a water heater and vent, $8.26 per water piping unit, $8.26 for a gas piping system serving one to four outlets. Incorporated cities such as Santa Rosa, Windsor and Healdsburg run their own building departments, and the Marin towns each run theirs. Those are agency fees, not our charges.
