Our Story

Nationally known as one of the oldest and most trusted interior construction companies in the Midwest, Allied has been meeting the needs of general contractors, architects, developers, building owners and managers for over 70 years. Allied Construction Services was founded in Des Moines, Iowa in 1950 by Robert Maddox. To accommodate growing business over the years, Allied has opened offices across the Midwest in Iowa, Illinois, Nebraska and Kansas. In the early 1970s Allied acquired Color Inc., which has since become one of the largest painting contractors in the Midwest.
