Great Northern Insulation

We were approved for the home weatherization program, and it was Great Northern Insulation that came in to insulate our attic and crawl space. Nick & Sean showed up on time, were quick yet efficient, as well as polite and did their best to clean up afterwards with minimal mess left behind. It was a great experience overall, and i'd highly recommend them to friends and family in the future!

Quick, professional, on time and job well done. Only suggestion would be for better clean up post job.

My installers Alex B & Justin D showed up on time. They were courteous, professional, and efficient. The work was completed quickly and they cleaned up the job site as best as they could prior to leaving. The crew took pride in their work. The GNI price was competitive. I took a look in my attic prior to their leaving and I amazed about how much insulation had been installed. I am looking forward to warm winters and cool summers. I would use GNI again and I recommend their services to others.

Excellent service and reasonable prices. We will be using them again for our next insulation project.

Entirely satisfied with GNI. Jasen and crew were courteous and professional. Also on time and clean. Good job.
