History of the Company:

Callow first began serving the Mahoning Valley’s residents in 1951 by Carl L. Callow Sr. At that time, the company was small and water problems were minimal as homes in the area were relatively new which only left repairs on homes with construction errors. In 1978, Craig Callow joined his father in business and the office and shop were built on Olive St and business began to increase with the aging of homes. As time went on, more and more foundation problems began to surface.In 1991, we expanded our area of operation by purchasing an additional satellite location in Hubbard, OH. We became the first company in the area to develop, install, and guarantee an EXTERIOR SYSTEM that not only kept your basement dry, but prevented further damage. Craig Callow Sr. and his son Justin work with the crew to ensure a QUALITY installation. WE ARE OPEN YEAR-ROUND for whenever your need may arise! Once you see our operation and business, you will know that we have made a commitment to be here for a “very long time.”
