Great Northern Insulation

Great company and thanks for Tom and Brian from the Barrie branch they arrived on time and quickly got to work, very careful and take care of our home when they were using the tools accessed from outside into home, they cleaned up quickly after they were finished.
Will gladly recommend GNI to our friends and family members.

Great company to deal with. We had Tom and Brian from the Barrie branch arrive on time, they quickly got to work and even cleaned up after they were finished.

Will gladly recommend GNI to our friends and family.

My experience with this company, without getting into details, left me to believe their office has more work than they can handle and the level of customer service from the office is less than what one would expect.
The positive side of this company was the workers on site. Very hard working guys and they do their best to work through any problems to finish the job to your liking.
I hired this company to replace a layer of saw dust, celulose, and batt insulation with spray foam and celulose to R60.

Hired Great Northern Insulation to spray foam the crawlspace under my home, as well as to blow insulation into my attic. They were professional from the first call to the last day on the job. They kept the job site clean, were prompt, and friendly. I had forgotten to mention that I needed more baffles in my attic, but they noticed and made my wife aware before they added the needed amount. I would highly recommend this company. In the world today, we never hear the good, only the bad: well this company is one of the good ones, if not the best!!! Thank you Angelo, Tom, Brian and all the other staff that made my house warmer and more energy efficient!!!

Needed new vapour barrier in crawl space. Contacted the company to get a free quote. Sales person arrived at the scheduled time, reviewed my requirements and provided a written quote before leaving. A scheduled date and time were arranged. The installation staff did a great job. Quick, Clean and very professional. Removed all old barrier and cleaned up the area. Very Pleased would recommend...

Very impressed with your knowledgeable, friendly staff. Aaron explained what we needed on an individual basis and also put on a slide show in our community centre as a number of homeowners were considering upgrading insulation.(very personable)
Tom and Brian arrived to do the job, they were clean and professional before ,during and after work was completed.
Job well done.
Thanks Ron Barrett

Renovating a chalet in the Blue Mountans; have spray foamed basement walls to R20; had issues with dampness. All gone; the guys did a great job! they are now coming back to do the rest of the house. Thanks Angelo for the great service.

great job from start to finish a pleasure to deal with. I had a very small job to do 200 SQFT in a single car garage although I thought on the high side of pricing for spray foam they came in at the best price and I am glad to have chosen them. excellent job and happy to have it done. I have noticed the difference GNI did for me

Although, I have no idea what my attic looked like before or after because I will not go up there, Brian and Tom came into my home with a friendly professional attitude and made me feel confident in their work. I knew this was right company as soon as I had Angelo come in and give me a quote and explanation of what they will be doing and the product they would be using in my home. Thank you guys for making this a good experience and I would definitely recommend Northern Insulation to anyone. Being such a busy company, I did not have to wait long at all for you to provide great service.

Recently we renovated our home with new siding, soffit and eavetroughs. During this time it was pointed out that our insulation was inadequate and it was recommended that we have new insulation installed to achieve R50 status. Dustin came to our house and explained what we had and what would be best to achieve maximum performance in all seasons. We were impressed with his knowledge and his down to earth descriptions of the process and the final results. After reading reviews of Great Northern Insulation we were convinced and decided to go ahead with the job.
The three men that arrived to do the insulation were fantastic. They explained what they would be doing, took all precautions in covering floors in our house and took the time to do a very thorough job. Dustin did come over while the job was being done to make sure we were satisfied and to answer any questions we had. The workers - Chris, Dave and Mike were excellent and very personable as well.
We are more than please with the work performed by Great Northern Insulation and highly recommend this company to anyone looking to insulate their home to current standards.
