I couldnt be happier with Great Northern Insulations work in my house. Jermaine, Ryan, and Gracie come to top up the extremely insufficient insulation that I had in my attic previously. From the moment they arrived, they took great care to protect my home from what could be a very messy job. After prepping the house, they quickly prepped the attic, protected the soffit vents, and boxed in the hatch with cardboard and foam insulation. Then Jermaine applied the insulation throughout the attic and it looks amazing. The end product will definitely improve our home and our comfort.

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 came and replaced the insulation in our attic space. They did a fantastic job. After the job was complete we still had some roof melting and assumed it was the insulation; Nick came with a thermal cam and was able to show us what the problem continues to be and that it was in fact not the insulation. Great company and super friendly. Highly recommended.

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, Amrish Patel Amrish Patel

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.
