Commercial Plumbing Credentials That Match High-Stakes Facilities

Commercial property owners and facility managers trust us because we bring the right credentials, insurance, and experience to every job. We are LA and Orange County certified for backflow testing, so we can handle both routine compliance testing and complex backflow repair programs for your properties.

We carry USL&H insurance and hold RSO certification, and we are a union plumbing contractor equipped to work on regulated commercial sites, including schools, hospitals, and industrial facilities. Our company played an integral role in the creation of Los Angeles building and plumbing codes in 1928, and that history continues to inform how we approach California Plumbing Code compliance today.

Most of our technicians have been with us for 10 to 20 years, which means your job is handled by a team that has seen and solved thousands of commercial plumbing challenges. We back our work with warranties on parts and labor, offer flexible financing options for larger projects, and provide service in English and Spanish to keep communication clear at every step.
