About Us

Simply solving complex challenges

We solve the complex challenges of built environments and their systems. Originating over 100 years ago to serve the Pacific Northwest as a mechanical contractor, our firm has expanded to a vast range of comprehensive, integrated services, helping clients and partners plan, build, and manage their buildings, facilities or construction projects. As these programs present inherent technical and logistical complexity, we rise to the challenge of removing worry, delay, angst, and confusion, so you can get back to focusing on what you do best.

We have a long history of providing clients with unique, budget-sensitive systems, completed on time. Along the way, we reduce energy and operational costs, help improve tenant and employee productivity, promote sustainable building environments, and remain accountable for the ongoing system performance of our clients’ facilities. Through our commitment to quality work—and through our philanthropic activities—we strive to have a positive impact on every community we touch.


Thinkers and builders since 1920

For over a century, UMC has developed and redefined the skylines of the Pacific Northwest. From humble beginnings as a small heating and plumbing shop founded by the Granston's in the early 1900s, we have thrived through significant historical moments - the Great Depression, World War II, the Vietnam War, a recession in the ‘70s, the technology boom then bust of the ‘90s, and the economic downturn of 2008. Today, we’re stronger than ever. Our diverse team takes pride in creating exceptional building experiences and innovations that will define this region for the next 100 years.
