      Great Northern Insulation was initially hired by a contractor to reinsulate our attic space. Unfortunately to do this job we had to remove the roof to access the attic. Our roofing company came and removed the rear of the roof to give GNI full access to the attic to apply spray foam and loose fill on top, we were charged $6264.72 for insulation. No one from GNI communicated with us while they were here. They were done in only a few hours and left. Thought the job had been completed until mid November when we got a heavy snow load and there was a 2 foot hot spot section all across the front of our house. The insulation crew did not insulate the entire space, rather did just over half of the attic but charged for the entire square footage. When in communication with GNI they tried to say the space was blocked and they did not have access to reach the entire space. To fix it we had to remove the front of the roof to give them access a second time to get this area covered. There was nothing blocking them from doing it right the first time, just laziness; and they had every excuse in the book. They had the audacity to send an invoice for the second application when they had already been paid in full to do the job the first time, this time charging an additional $2825 to repair. They were also to remove the old insulation from the property when the job was complete. Great Northern refuses to take the old insulation with them and instead left it in my driveway. So after all of this and now having paid them $9089.72 for insulation, there is still a hot spot across the roof where they still haven’t done it properly and I have to figure out how I’m going to dispose of the old insulation. **** ******* ** ******* *** * ***** They don’t care about their workmanship and won’t take responsibility for it either. For your own sake, do NOT hire this company!

      GNI completed a large attic insulation upgrade in our condo community several years ago. We recently had an issue in one unit. We ask GNI to come and inspect it he attic. They found some substandard work that was done by their crew. They have quickly returned to make the corrections and improvements to resolve our issue. Their supervisor and the crew that came back were very professional. The affected owners were impressed and appreciative of the extra work done. GNI is to be commended for their honesty, thoroughness and customer service.

      Mike, thank you for this review. While we always hate to hear when our employees did not deliver the highest quality, we are always proud of our team members who make it right and represent our values. We hope that you enjoy the added level of comfort...knowing that the job was done right.
