Thank you for visiting First off, we want you to know BAJA Plumbers in not a franchise plumbing service nor do we outsource work to plumbing service contractors. Many web sites today are "marketing sites" associated with hundreds of different plumbers from around the country and they outsource leads. This web site is not one of those. We send our own licensed plumber when we fix plumbing. Our licensed contractors, California residents, will solve your plumbing problem.

We are a boutique plumbing company located right here in Antioch, CA, family owned and operated, and in business for over 30 years.

BAJA Plumbing, Inc. services homeowners, apartment complexes, and industrial parks in Martinez, Pittsburg, Antioch, San Ramon, Clayton, Walnut Creek, Concord, Lafayette, and Pacheco, CA.

Our clients tell us we are the best plumbing service company in Contra Costa County. That means a lot to us. Not surprisingly, we get many of our new customers thought referral, and if you are one of them be sure to tell us who referred you when you call. We'll be sure to send them a thank you card.
