The original building on this site was Pitkin's Store, which burned in 1870. In 1886, W. E. Drew bought the rebuilt store and refitted the building, and it became known as Drew & Churchill before burning in the fire of 1901. Warren Drew then rebuilt a two-story structure, and the Colebrook Hardware Store opened in the northern section, advertising entrances from Pleasant Street and Main Street that are still in use today. Over the years, apartments and businesses occupied the upstairs. In 1956, the building was sold to Parker A. Hicks, Sr., who continued the hardware business until his death in 1965. Richard and Parker, Jr. inherited the business, continued the hardware store, and incorporated it with Hicks Lumber Yard. In 1971, Richard became the sole owner and later converted it to P.A. Hicks & Sons. In 2006 and 2007, the building was completely remodeled and Hicks Hardware expanded into the entire Union Block. Colebrook also had its first telephone in 1876, and the New England Telephone Co. was located upstairs in this building from the 1930s until 1965, when the dial system was installed.
