We had a garage that was so cold in the winter that it was affecting other parts of the house. We ordered for home insulation services with gni to remedy that. Paul and Jeff came onsite and were an excellent crew. They went through the process and clarified our order, working quickly and diligently. The garage is warmer already.

We had our bibs system installed in our new cottage. We also had our ceiling insolation as well as spray foam in the rims. Very impressed with the work done.

Joel and Gabe arrived a bit early to insulate our attic. They put down plastic and removed their boots, were pleasant, worked quickly and cleaned up after themselves. I would recommend them for a job well done with minimum interruption to your household.

My daughter knew I was considering getting more insulation, and recommended GNI to me as she was very happy with the work they did for her. Rob came out and did the estimate. He was pleasant and professional; a very good first impression for the company. When the guys came out to do the work they were on time, efficient and again, very professional. They also did a great job on clean-up. I'd hire this company again anytime.

I submitted a request for a quote and Angelo got right back to me. The quoting system is very slick and easy to use !!

This morning I had my attic topped up. Brian and Rob were great !! They were perfectly on time and very courteous. They used drop sheets and cardboard on corners so the hose would not scratch anything. They also cleaned up when they were done... Give these guys a raise, they deserve it.

I highly recommend GNI...

Sean, Bill and Phil were very professional and efficient. They worked quickly to get the job done, with minimal disruption to my daily routine. They arrived on time as scheduled, and immediately identified themselves. Provided an explanation of what would be done. Cleaned up afterwards, leaving no trace that they were even here.

Great customer support Eric was a beauty!! love the work well done. They were fast and efficent, cleaned up after completeing the spraying. Qoute was submitted with tons of proffessionalism.

Following an energy usage audit of my home I discovered the insulation
value in my attic was R25. A family member recommended Great Northern Insulation Contracting Ltd. whom I contacted to arrange an inspection and a quotation to increase the rating to R60. The installation was completed during the following week. I highly recommend Great Northern.The company and their staff were a pleasure to work with.

Very good service and the quality of the job was good, I was getting a liter of moisture being captured by my de-himidifier. In my cold room. Afterwards there was no moisture build up as the closed foam insulation did the job.

We had work done to different homes in the past week. In the most recent installation. the team of 2 (Sean and Craig) arrived a little early and asked politely if it was ok to start ahead of the scheduled start time which was appreciated. The job was done professionally and quickly. Both of them made sure to lay plastic over the hardwood floors especially since it had just snowed during the day. At the each job, they cleaned up and left the home tidy. Both jobs were completed professionally and I would recommend this company
