Our Company

110 Years
In The Making

This kind of history doesn’t happen by chance. For over 110 years, we’ve built our reputation through hard work, good people, and solid relationships.

Our Performance
Builds Relationships®

We design and build HVAC, plumbing, and architectural sheet metal solutions across Northern California and Northern Nevada. Our team works closely with contractors, owners, and project teams at every stage.
Everything is handled in-house — from early planning through installation and startup — reducing handoffs and keeping projects moving on schedule.

A Culture Of Safety

At FMB, the safety, health, and well-being of every member of our construction team is our highest priority. We are committed to creating job sites where safety is built into every stage of planning and execution.

Prevention of workplace injuries and occupational illness is a core responsibility of our OSHA 30-hour trained foremen and is integrated into both daily operations and long-term project planning. Safety is not an afterthought—it is foundational to how we work.

FMB enforces a strict Injury and Illness Prevention Program (IIPP) that sets clear expectations for every team member. This program requires a disciplined, proactive approach to safety and full cooperation in all health and safety practices across the organization. We believe that a strong safety culture is only possible through teamwork, accountability, and shared responsibility.

Through the commitment of every FMB employee, we continuously strengthen our safety performance and foster a work environment where people can perform their best work with confidence.

Our ultimate goal is simple: to eliminate preventable injuries and illnesses on every job site. We pursue this objective relentlessly, every day, on every project.
