Honest work and clear communication

Jermaine and Ryan came by to work on attic insulation and blower-door draft-proofing for us. They were courteous and punctual. Upon arrival, they communicated their work to us and helped us understand the crucial parts of the house that needed work, allowing us some time to clear our clutter to free up the space for them.
They took the time to protect our furnitures and bedroom from dust. And they cleaned up before they left.

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.
