We proudly serve San Diego, CA and surrounding areas
Founded in 2011 by master plumber Jose Martinez, JL Martinez Plumbing Inc. was built with a clear vision: to strip the stress out of plumbing emergencies by providing uncompromising technical mastery, total cost transparency, and ironclad integrity.
Before managing the company full-time, Jose dedicated years to molding the future generation of tradesmen, serving as an elite Plumbing Instructor for premier institutions across Southern California—including the PHCC of San Diego, ABC San Diego Chapter, San Diego Job Corps, and San Diego City College.
This deep commitment to the absolute highest standards of code compliance governs everything we do. Our background sets us apart on the most complex water infrastructure systems:
Municipal-Grade Credentials: Holding Grade 3 Water Distribution and Grade 2 Water Treatment designations, we navigate heavy technical engineering parameters with absolute precision.
Certified Cross-Connection Control: Fully ABPA & AWWA certified to safely test, install, and service critical commercial and residential backflow prevention systems.
OSHA Instructor Certified: Operating with OSHA 500 & 510 training ensures your home, commercial asset, or industrial facility is treated with unmatched safety and structural risk management.
We reject high-pressure sales tactics. We focus solely on delivering honest, long-term, flawless engineering—whether we are solving a hidden underground mainline leak, clearing stubborn blockages, executing a seamless premium copper repiping project, or performing zero-dig trenchless CIPP structural sewer lining.
When you hire JL Martinez Plumbing Inc., you aren't just hiring a plumbing company. You are putting your property in the hands of the master instructors who set the standard for the entire San Diego plumbing industry.
