I was extremely happy with the service of all the staff that I dealt with, both in the scheduling office and the installers. The installers in particular were very helpful in explaining things, and did an excellent job.

We were very satisfied with the guys work. They laid plastic across living room floor and up the stairs . They covered the furniture around the attic door. They were very polite boys. The boys cleaned everything up when they were done. I didn’t have to vacuum upstairs or downstairs when they left. I was very proud of the work. You can pat the lads on the back. Thanks for everything.

We want to let you know we were very impressed with Great Northern Insulation's customer service and promptness in responding to our questions! Given the nature of our project (an old cottage renovation), there were a number of very challenging issues, for example, the treatment of the area where the old cottage roof met the new addition's roof.

Sean and his team were patient, thorough, and very professional in conducting the work.

The project required more time then originally contemplated and the Northern team was very responsive in finding additional time for the team to finish the work promptly.

On our return when the work was completed, the cottage was spotless, not a drop of insulation on furniture or flooring. We had also forgotten when they began the work to have them cover the main exposed beam and they had already proceeded to begin to spray. They promptly cover the beam at our request. But when cleaning up they had actually gone back and cleaned the beam up...Unexpected! Bravo and thank you!

A great experience and our thanks to the Northern team!!

Insulating our attic as best as possible according to how our house is structured

We called 2 previous companies and great northern insulation were the only ones to take on our project. It wasn't too small for them. They came on the day they said they would and left the house in a clean state. Wouldn't hesitate to recommend to our friends.

I believe your crew and firm deserve a "Job Well Done" for the basement work completed on Oct. 6, 2015. Kevin and Kevin make a great team. I felt completely at ease leaving the home in their care. The work done was clean and precise. All I have to do now is add drywall. We are exceptionally pleased and will mention our experience to others.

A few years ago, we had an entire house spray foam insulated by GNI as we completely renovated an old farm house. The very low Natural Gas heating bill for this home was astonishing. Because of this, we recently had GNI spray foam our basement rec-room. Beautiful job showing careful craftsmanship in applying the product. Even my dry-waller commented on what a great job GNI had done. Thanks again.

Home Insulation

Our family was part of the Union Gas Home Weatherization Program. Scott and Jeff were the gentlemen that installed our insulation. They showed up on time, introduced themselves, and made us aware of the amount of time they would be there each day. Every day they were here they made sure the items in my home were covered, and they vacuumed before they left.
Both of them were very informative regarding the products that they were using, and the way that the products will insulate my home. While they were working, they never made it so I couldn't be in my home. They were here for three days, as my whole house needed insulating, and at the end, my house was a clean as it was before they started. Good, professional, and nice guys to boot. Will recommend to others:)
