Upgrade of attic installation in 24 year old house

The GNI team (Paty, Frank and Jeffrey) did an excellent job in upgrading my attic installation. They arrived on time, explained what would be done, and showed me before and after pictures of all their work. They protected surrounded areas and vacuumed after the job was done.
They were very professional. 5/5

Insulating the attic in an older home

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.

Attic Insulation

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.

Hi Brent & Jena, We would like to apologize for the frustration you've been experiencing recently. We want you to know we appreciate your feedback. For your upgrades, we were subcontracted by your roofing company to complete the insulation work, and we did complete everything as quoted with that contractor, including a change order. We’re happy our technicians were able to remove and dispose of the old insulation, and that our representative Chris has been in contact with you to further assist. Should you have any further concerns, please reach out to Chris who will be happy to assist you.

Attic insulation

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.

Attic insulation

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,

Good work!

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
