Great Northern Insulation

I got a recommendation for this company, with a time sensitive case they made it work asap and did an amazing job and were very friendly. Very pleased And satisfied.

After discovering that we had almost no insulation in the older part of our renovated home, we called Great Northern Insulation. Their rep came within a couple of days to assess our needs and provide us with an accurate financial estimate. We booked our appointment and within 2 weeks the company was here to do the work. They arrived well within the estimated appointment time. Both Phil and Billy were very professional, very courteous and very thorough. They were here for a couple of hours and when they left, you would never have known they were here. There was no dust, dirt or debris left behind and within hours, I can feel the difference in our home. So a big thank you.

From order a quote to having blown in insulation installed the staff at GNI were amazing and professional. They arrived on-time and were knowledgeable and concerned about my satisfaction with the quote and the installation.
The installers were polite, punctual and professional and thorough. They cleaned up after the work was finished so you would not even know they were here.
GREAT JOB GNI!!!! I would recommend GNI to anyone!!!!

The two service providers, Sean and Craig, were polite and efficient. Introduced themselves and were able to keep the house clean. When done, they insured it was all cleaned up. Thank you for a job well done.

Both Great Northern teams completed two projects professionally and on time including: basement (poly) and attic (fibre) insulation. Based on heating cost reduction this represents a good investment. I would recommend them to other homeowners.

The spray foam crew was great ! They were a father son team who took pride in their job . Everything wash masked off properly and the job was done properly as well. The blow in crew was though and quick and left no mess anywhere . I went with GN because they were the best price out of the 3 companies I had quote. My experience was great and I would recommend them .

Great Nothern Insulation gave us a thorough presentation of what to expect when insulating a part of the basement. Booklets received helped us to understand the methods used in order to render the service. The installation went all well with the proper followed up paperwork. Thanks to Phil and Billy for their professional though friendly service.

Great Northern Insulation lives up to their name. They were GREAT. From the time of the quote to the day of the actual insulation was less than 3 weeks. The team was very professional, tidy and efficient. And what a difference the spray foam made to the warmth of the house. I recommend GNI to everyone! Thanks for the Great job.

Very happy with the blown-in cellulose insulation added to my attic. After having a home energy audit done, I was told I only had R6 in my attic. Hired GNI after getting 3 quotes and their price was the most competitive. I have a room over my garage that has always been freezing cold in winter and hot in summer, and I thought it was just because it was above the garage, but the GNI crew told me that there was NO insulation above that room (I guess the builder got lazy and didn't insulate that part of the attic). After the celluluse was added, I am shocked at the difference in that room - huge difference in the temperature...it's no longer freezing cold. The GNI crew were neat and tidy. Very pleased.

The team of 3 arrived a little early... no problems. They put protection over anything that their hose might chafe and went to work. Apparently, our attic was 'easy to do' because of the older roof joist pattern. They were in and out in less than 2 hrs... 18" full depth.

Very personable and professional. two were experienced, and one was a bit of a deer in the headlights. They treated him well!

Would be my pleasure to recommend.
