About Us... Detroit Electrical Services LLC, was founded in 1999. On June 5, 2013 we became DES Electric and we continue to provide specific services to the electrical construction industry. These services include design, engineering, management, consulting, installation, and maintenance. DES has significant field operations today and a growing backlog of work. Our primary focus is on facilities and site work. Within this area we intend to place particular emphasis on the water/wastewater markets. This emphasis is due in large part to the expertise of the individuals employed by DES.
