About Us

17 Years
Of Experience
In The Plumbing & Piping Industry

JMG Mechanical Contractors LLC, is a family owned and operated company located in Vacaville, California. We strive to meet the ideals of professionalism, everyday.



Our company is supported by a strong team with an array of strengths and experience. We are aware that many other plumbing contractors claim to have "certified" plumbers. Have you ever wonder what that means? Where do they get their certificate to become a plumber?

To JMG Mechanical, our "certified" plumbers mean each plumber has completed an actual apprenticeship program. That program requires a minimum of 800 hours of classroom instruction and 7,200 hours of on-the-job training during the 4 year duration. This program is also federally and state approved.

Our apprentices and trainees are enrolled in the same training program as well. We invest into their future to produce a trained and skilled workforce. A huge value not added by most plumbing contractors.


On going education is key. We partner with manufacturers and suppliers for lunch-n-learns and other trainings for certifications to install or repair their products.



Five days after graduating high school, Jared Goodreau started immediately working in the industry while being enrolled into an apprenticeship program approved by the State of California. He turned out as as state certified journeyman after successfully completing the program at the top of his class.

A few days after completing the apprenticeship program, Jared enrolled himself into Autocad courses for detailing of plumbing and piping systems.  During this time, Jared was promoted to a Project Management/Estimating position. He found himself estimating and managing multiple multimillion jobs. 

To date, Jared has managed projects up to $25 million in size. These jobs ranged from commercial, residential, and industrial. He was traveling throughout California by plane, car and train to manage multiple jobs at once.  He was heavily involved in all aspects of delivery methods from Design/Build, Design/ Assist and Plan/Spec.

After starting a family, Jared decided to open JMG Mechanical Contractors, LLC. Providing excellent service and performance while engaging in his true passion of plumbing and piping. He prides himself on honesty and fairness. Jared is here to help and ensure that his team meets the ideals of professionalism on every level.
