About Malachi Plumbing in Oakley, CA

Three Decades of Licensed Plumbing Service in Contra Costa County

Malachi Plumbing is a family-owned and operated plumbing company serving Oakley, Brentwood, Antioch, Concord, Pittsburg, Pleasant Hill, Walnut Creek, Lafayette, Alamo, and surrounding areas. Licensed, insured, and bonded (License #1072451), the company brings more than 30 years of combined industry experience to every project you entrust to them.

When you work with a family-owned business, you experience a level of accountability that matters. Your calls are answered by people who built this company and whose reputation depends on your satisfaction. That approach shapes every estimate, every appointment, and every installation or repair they complete.

Three decades in the plumbing trade means they've handled everything from straightforward fixture replacements to complex repiping projects. They've diagnosed stubborn leaks, cleared drains that defied DIY solutions, and retrofitted water heaters in homes with challenging access points. That breadth of experience translates into faster troubleshooting and solutions that hold up over time.

You benefit from that depth when a technician can identify a failing pressure regulator before it damages your fixtures, or recognize that your recurring drain clogs stem from inadequate slope in older cast-iron pipes. Experience reveals patterns that save you repeat service calls and unnecessary replacements.
