The Preferred Source

George Hartwell began the operations of Hartwell Excavating in 1950 as a small construction company with a backhoe and a dump truck focusing on digging basements. Shortly thereafter, Hartwell moved into small utility work. On July 25th, 1975 Kennaday Paving joined forces with Hartwell Excavating to create HK Contractors, Inc. We have been a mainstay of Idaho Falls and the surrounding areas ever since. As one of Idaho’s largest construction and material supply companies, we have also expanded our service area to include Montana and Wyoming.

Through the years, we have received numerous local, state and federal awards for outstanding work quality and performance. Included among these awards is the “Best Construction Project” for 1998, 2003 and 2004 from the U.S. Department of Transportation, Federal Highway Administration.

On November 5th, 2007, HK Contractors became part of the Oldcastle Materials team of companies. This increased our abilities by providing more resources and increased purchasing leverage.
