Common questions

Questions about our services

What plumbing services does Avanté Plumbing offer?

Avanté Plumbing offers 18 services across Sonoma and Marin County, grouped into repairs and maintenance (leak detection, clogged drains, toilet repair, water heater repair, garbage disposals, gas lines, pump and well repairs), installation and replacement (water heaters, fixtures, whole-home repiping, sewer main lines, water softeners, appliance water lines), and specialty work (sewer camera inspections, trenchless sewer repair, hydro jetting, backflow prevention testing, kitchen and bathroom remodel plumbing, and commercial plumbing).

Do you handle both emergency repairs and planned installations?

Yes. The same team handles an urgent failure — a burst pipe, a blocked sewer line, no hot water — and planned work such as a repipe, a water heater replacement or the plumbing for a kitchen or bathroom remodel. We are reachable Mon – Sun, 7:00 AM – 7:00 PM.

Do you offer HVAC or solar water heating?

No. Avanté Plumbing holds a C-36 Plumbing licence, which covers plumbing only. We do not take on HVAC or solar thermal work, and we would rather tell you that up front than take a job we are not licensed for.

How do I know which service I need?

You often will not, and that is fine — describe the symptom rather than guessing the cause. Water pooling under a water heater, a drain that empties slowly, a pump that keeps starting: each points somewhere different, and diagnosing it correctly is our job, not yours.

Do you charge for a quote?

Call (707) 231-0790 or send the details through the contact form. We diagnose the problem first and quote it before any work starts, so you can decide with the number in front of you.
