Great Northern Insulation

This company is very respectable. Their workers are friendly and knowledgable. Bill and Matt were personable and got the job done in an efficient manner. I would highly recommend GNI to my friends and family. Thank you!

Very happy with the service that they provided and were on time. the installers were courteous and cleaned up after work was complete. Fair pricing and would definitely use them again.

We are Snowbirds who came home to find that a Raccoon had taken up residence in our attic over the winter. Once rid of the animal it was apparent that it had done a lot of damage to our attic insulation making a nest etc. We Contacted several Insulation Contractors to get estimates. The representative from Great Northern Insulation seemed the most knowledgeable. The installers showed up on time, were friendly and cleaned up after they had completed their work. We are very happy with the service we received.

The guys were very professional did a good cleanup job and explained the process and we're done in a timely manner
I would definitely recommend their services to my friend and family

I've had a number of heating and Cooling issues over the years and finally did something about it. the aftermath required a 'top up' of insulation in the attic. Great Northern Insulation was recommended by a reliable contractor i had used several times in the past.

The experience with Great Northern Insulation started with a very friendly and knowledgeable free in-home consultation, followed by prompt scheduling of the service. Service team were extremely friendly and kept me informed the duration of the service engagement, as well as informing me of some minor issues they identified and worked with me to resolve. Their post-work clean-up was phenomenal!, almost like they weren’t even there!

Highly recommended!

Hired Great Northern Insulation to sprayfoam my garage ceiling as I am fixing a builder provided insulation job that was poor to say the least. Alana came by within 1 day's notice to review my work area and provided a quote not even 24 hours later. Quote was detailed and scope of work was clearly laid out. One of the reasons I chose Great Northern is that they were detailed and took time to explain. Other companies (some which are more known and seen on shows like Holmes on Homes) were careless with their quotes, they rushed, and weren't friendly or wanting to take the time to explain. 2 weeks later, the Barrie branch was swamped so a crew of 2 (Daniel and his colleague) from the Perth branch drove all the way to Brampton and completed the job in 6 hours. The place was covered and kept tidy and the job is absolutely amazing and surpasses my standards, which is often hard to do! I cant thank Great Northern enough and Daniel and his colleague (sorry forgot his name!) and will definately be using Great Northern to finish my basement down the line and redo my insulation in the attic. thanks again!!!!!

No issues and Derek and John were very good. Price was lower than others in the area and the product was the same. Work was done on time as promised and any debris was cleaned up by the workers leaving no mess.

I had GNI do a top-up insulating job in my attic of 1900 square feet. They accommodated a change I made in the date scheduled and were very prompt and efficient on the new date that we set . The three employees Derek, John and Brian J were courteous and very efficient and great to work with. I would highly recommend GNI for any insulating job in the future.

Alex B and Nick did a great job and there was nothing to clean up.
I appreciated their professionalism. they arrived on time and worked till the job was finished. Thank You.
