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.
