We worked with Chris, Nick, Mike, Dan, Darren, Matt and Vanessa at the Port Perry Branch. The staff at GNI was informative, friendly and arrived on time. We used this company to complete the spray foam insulation on all exterior walls of our home (upstairs and downstairs) and to poly our attic ceiling. They completed the job in a professional and timely manner. We are very pleased with the work completed and will be sure to pass along the company and use them in future renovation projects.
Thank you for the 5 Star review. We are happy to hear how impressed you are with our Team. Here at GNI, our top priority is customer satisfaction and I am so thrilled to hear that you got to witness it first hand! Thank you for choosing Great Northern Insulation.

GNI did a big attic project that took 3 days and we are very happy with the end results. Ross, Dave H, Aaron, Marv, Shawn and Phil were polite and very informative as I had many questions and they had answers every time. When they finished they made sure I was happy with the work before taking off. I'd would recommend them to friends and family and call them back for future projects. Thank you everyone and a big thank you to Matt in sales for helping us find the solutions to our attic problems.
