Fault Line Plumbing

Who we are

Fault Line Plumbing, Inc. is a plumbing, mechanical, and fire protection contractor based in Livermore, California. Founded in 1997 as a plumbing contractor, we have expanded into boiler and fire sprinkler work while growing organically over the decades.

What we do

We provide new construction plumbing and fire sprinkler services throughout Northern California. Our specialized mechanical division handles steam and hydronic systems, including boilers. Our work supports sanitary disposal, potable water, fire protection, and resource-efficient heating.

Working at Fault Line Plumbing

We train our plumbers in-house rather than subcontracting our plumbing workforce, with an emphasis on consistent installations and repairs. Our culture emphasizes safety and self-supervision, and we expect the same standard of workmanship on small projects as on large ones. We welcome applicants from apprentices through supervisors and make apprentice mentorship part of our mission, helping people develop skills to support themselves and their families.
