Navigating the complexity of the built environment, we create spaces that make people more confident, comfortable and productive. UMC has been a proud union company serving Washington and beyond since 1920. 

UMC helps clients solve the complex challenges of built environments and their systems. Originating 101 years ago to serve the Pacific Northwest as a mechanical contractor, the firm has added a vast range of comprehensive, integrated services in facility performance and maintenance, energy and environment, building automation, and manufacturing. UMC helps clients and partners plan, build, and manage their buildings, facilities, or construction projects. As these programs present inherent technical and logistical complexity, UMC rises to the challenge of removing worry, delay, angst, and confusion, so their clients and partners can get back to focusing on what they do best.
