Current company JCM Associates
Construction · 128 employees · Founded 1987 · Upper Marlboro, Maryland, United States
Founded in 1987, JCM Associates, Inc. has grown from a three-person startup into one of the Mid-Atlantic’s premier mechanical contractors, serving the Washington, DC, Maryland, and Virginia markets.
Today, JCM is a trusted partner on some of the region’s most complex and high-profile commercial construction projects—ranging from data centers and healthcare facilities to laboratories, mission-critical infrastructure, and large-scale mixed-use developments.
What sets JCM apart is not just what we build—but how we build it.
We are a people-first organization driven by a strong culture of leadership, accountability, and continuous development. Our teams are built from the field to the front office, combining deep trade expertise with disciplined project management, advanced planning, and cutting-edge construction technology.
Our services include:
• Mechanical and Plumbing Construction
• New Construction, Renovation, and Mission-Critical Projects
• Design-Build, Design-Assist, and Plan-Spec Delivery
• Prefabrication, BIM Coordination, and Advanced Project Planning
At the core of JCM is our “Culture of Cooperation”—a commitment to collaboration, integrity, and execution. We partner closely with owners, general contractors, and trade partners to deliver projects safely, efficiently, and at the highest level of quality.
JCM Associates is not just building projects—we are developing leaders and setting the standard for the next generation of mechanical construction.
