Plumbers in Napa, CA

Written & reviewed by Founder, SEO Local · 22 years in SEO · Updated October 2026 · LinkedIn

There are 47 plumbers in Napa County according to the US Census - that's what they say anyway from those County Business Patterns reports. I found just one mapped by name using OpenStreetMap though. It’s pretty basic here: only one has a phone number listed, and another links to a website. These listings are free, which is good; any business owner can claim their page on hashtag.org if they want to.
