About Us

For about 27 years, Marin Mechanical has been a part of the local construction industry building high quality structures. Founded in 1993 by a team of ambitious professionals, Marin Mechanical merged a wealth of experience and skill into a company that has earned a remarkable reputation as a leading contracting company in Marin County. Mark Silvia, John "Jack" Wise, and Jon Silvia combined their strengths to create a family environment in the plumbing world. They promised at the time they decided to form Marin Mechanical that they would always operate with a quality foundation of unwavering ethics and quality workmanship.It is by these goals that we serve our community today.

Marin Mechanical currently has 6 Owners; Mark, John, Tony, Jeff, Brendan, & Jarrett. Mark & John were inspired to start a business  in which they could reflect their own work ethic and skilled craftsmanship. The current owners of Marin Mechanical are uniquely qualified to work in the Mechanical/Plumbing business due to their knowledgeable experience in multiple specialty trades. The owners are excited to run Marin Mechanical II because of the satisfaction that comes from hard work, overcoming daily challenges, and the teaching of these values to employees.


Our business has grown over the years, as well as our knowledge and understanding of the trade. We perform well on jobs large and small focusing on quality craftsmanship, attention to detail, & customer service. Our specialties have grown to include Residential & Commercial Plumbing and Drain Cleaning, Water Heater Installation, Boiler and Radiant Heating Installation, Minor Residential Electrical, System Troubleshooting, & Design.
