Great Northern Insulation

Improper installation of fibreglass insulation had created moisture and mould on and in a kitchen ceiling and under the roof. The best solution from my contractor was foam insulation, and i was impressed how the installation was easy, and great care was taken to contain the spray. Virtually no fumes or mess was created, and i could hear and feel the difference immediately ! ! Great job guys, and great product...

We had a condensation issue that was marking our living room ceiling. We called GNI call was very promptly returned. Within a day or two, Jason attended our home, went up into the attic and explained our problem very thoroughtly and clearly. He gave us a very accurate estimate. Within a few days, only because we weren't available earlier, the technicians came. Matt and John were extremely professional, courteous, friendly and very knowledgable in every aspect of their work. They answered any additional questions we had and carried their job out with great pride. They clearly like what they do and are very very good It. The were tidy and cleaned up any mess that was made. It really was a pleasure to deal with Jason, John and Matt, our only wish was that they did more as we could certainly call on them for any other work we would need done in our home, we were completely confident with them and their work. Thanks for a great job, it was a very good experience.

We had our garage insulated with spray foam. The team from Great Northern Insulation were wonderful. They were on time, on budget, clean, friendly, very fast and efficient. Thank you!

I had the job done 1 1/2 years ago and was seeing moisture on the ceiling beside a pot light. I called and they came out and saw the problem. The insulation had blown away from the eave and was the reason for the moisture.
They came out later and fixed the problem in 2 hours. Great job!

We took down the bulk heads in our kitchen during a reno and was surprised to find we had very little insulation in the attic. We looked online and Great Northern came up. Not knowing who to call, I called for information. They were so helpful! The technicians (John R. and Dan O.) just left and I can't say enough how impressed I was - they were so courteous, friendly and neat. We are so pleased we went with this company and would recommend them to anyone!

Great job. Very efficient and timely. Very clean and friendly. Great product delivered in an professional manner. I would recommend this company. Great price too! Thanks guys, we have noticed a big change in the temperature upstairs.

Recently hired Great Northern Insulation to top up our attic and spray insulate a few problem areas. They were super busy but were able to accommodate us and get the job done within a week after assessing our attic. Wonderful company, great service, and the men that came to do the job were very professional. Thank you to the entire team at Great North Insulation.

This company was great. Excellent customer surface. Fair priced and High quality of work. I will most definitely recommend this company and will use them again for future renos . Thank you again.

We researched and had several quotes. These folks are the best. Friendly and educated employees who answer all your questions. They arrived (my hubby thinks Duncan was one of the crew) on Jan 9 as scheduled. They did everything they said they would. Answered any questions. They were efficient and cleaned up after. More than satisfied with the work and see a big difference in our sunroom since the work was done. Thanks very much!

I just wanted to say this was the best customer service I have ever received. The Lead guy said he would treat it like his house and that was such a great feeling. Really awesome guys and totally did a great job. I feel HEAT UPSTAIRS NOWWWWWWWWWWW.
