Jermain and Jamal did some great work. Noticed our exhaust fan for bathroom was never installed. They installed it no problem. Great work by them. Good guys!

Great Northern Insulation was initially hired by a contractor to reinsulate our attic space. Unfortunately to do this job we had to remove the roof to access the attic. Our roofing company came and removed the rear of the roof to give GNI full access to the attic to apply spray foam and loose fill on top, we were charged $6264.72 for insulation. No one from GNI communicated with us while they were here. They were done in only a few hours and left. Thought the job had been completed until mid November when we got a heavy snow load and there was a 2 foot hot spot section all across the front of our house. The insulation crew did not insulate the entire space, rather did just over half of the attic but charged for the entire square footage. When in communication with GNI they tried to say the space was blocked and they did not have access to reach the entire space. To fix it we had to remove the front of the roof to give them access a second time to get this area covered. There was nothing blocking them from doing it right the first time, just laziness; and they had every excuse in the book. They had the audacity to send an invoice for the second application when they had already been paid in full to do the job the first time, this time charging an additional $2825 to repair. They were also to remove the old insulation from the property when the job was complete. Great Northern refuses to take the old insulation with them and instead left it in my driveway. So after all of this and now having paid them $9089.72 for insulation, there is still a hot spot across the roof where they still havent done it properly and I have to figure out how Im going to dispose of the old insulation. They dont care about their workmanship and wont take responsibility for it either. For your own sake, do NOT hire this company!

We had additional insulation blown into our attic, as well as additional insulation added to two hatches. The team was on time and efficient. They did a great job and cleaned up after themselves. Our house is now a lot warmer.

Very professional services and crew worked beyond expectations. All work was done on time and entire process was very satisfactory.
Crew protected all carpet and stairs area with protection cloth and vacuum the place if any debris there.
We are very happy with the Great Northern Insulation company and their crew.
Work was done on time and price was very reasonable.

We would definitely recommend anyone who need to use their services.
Thank you,

Installers:
These guys are a v v important part of the process. Thankfully, my 2 guys Jermaine and Jamal answered all my questions patiently, which i most appreciate. They took awhile to get started, which i didnt understand. However, then they put the time into the job, which seemed appropiate. Really, time will tell how the job was done.
One minor suggestion is for them to have a few more screw drivers on hand just incase.
Sales guy:
Again, this person, Alex, answered all my questions patiently. One suggestion for future clients is to have Alex view all parts of the attic so that no surprises come up.

Again, this person, Alex, also answered all my questions patiently. I would just suggest that

Very pleased with GNI all around. Prompt quoting, sensitive to adapting to COVID schedule changes, once booked they adhered to schedules and plans, friendly and knowledgable staff, tour of the finished product at completion, thorough clean-up afterward, minor overspray issue was dealt with promptly. We would recommend them without reservation.

Great job with high attention to detail and products used. Have built many custom homes and GNIs work was excellent at a fair price.

GNI workers are very pleasant and professional.
All issues were dealt with in a timely manner.

Great job. Thorough and clean. No damage to anything. Very satisfied. Guys were friendly too.

Guys showed up and went right to work . Evident that they knew what they were doing. Protected floors and carpets on way in and out , were friendly, accommodating and cleaned up after they were done, not to mention I noticed difference walking upstairs the same day. Great job and highly recommend. Thanks !!
