Plumbers in Concord, CA

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

There are 318 plumbers listed in Contra Costa County according to the US Census - that's what they say anyway with their County Business Patterns data. I looked them up through OpenStreetMap and found zero mapped by name. None of those listings include a phone number either. And wouldn’t you guess? Zero have websites linked. These are free listings, though. Any business owner can claim their page on hashtag.org, if they want to.
