Our experience with Great Northern Insulation (GNI) from our first contact to the completion of the Work has been excellent. The work crew ,made up of Bill and Kyler, showed up on time, completed the work to perfection and left the work site spotless and clean. Bill and Kyler were professional and courteous. If you are looking for a reputable spray insulation contractor I would highly recommend GNI. We had a very good experience with this company. Evan & Sue - Four Mile Island - French River - Ontario
