For decades, building owners and managers have been forced to choose between price and performance in their facility upgrade projects. This is no longer the case with Entegral Solutions Group, a newly-created division of DFW-based DMI Corporation (d.b.a. Decker Mechanical) that is combining high quality and low cost into a new industry-leading approach for purchasing energy and facility upgrades.
DMI installs, repairs, and modifies existing plumbing and HVAC systems, working together with our other departments for on-time accurate, and emergency repair.

DMI was formed in 1984 with just six employees and a determination to succeed. Today, we are a multi-million dollar operation with an unrivaled reputation, a proven work quality, and an employee base over 200 strong. Our stragetic growth is not accidental, but a direct result of our commitment to quality, our dedication to our clients, and our proficiency in state-of-the-art mechanical services.  

About Us
DMI is a full service mechanical contractor with the equipment, staff, and expertise to plan and install large, small, simple, or complex projects.

Our welding trucks along with our professional welders and pipefitters provide state-of-the-art piping techniques. Our master plumbing crews complete our capabilities of being a full service mechanical contractor.
