Job and Ericson did a great job spray foaming our Muskoka room. Impressed with their attention to detail. Even did a little extra by spray foaming our attic hatch. Would definitely recommend

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

The whole GNI team provided top service that met all of our needs. Bill sprayed insulation under our boat access cabin - even the far corners that I thought were too hard to reach. The sales and admin staff were great to deal with too.

Bill and Kyler worked on our garage and they were wonderful! Clean, detailed and courteous. We will definitely call them again for our next project.
