Great Northern Insulation

Jermaine, Harpreet and James were wondeful, they took their time to set up, cleaned up after themselves, polite, courteous and did an excellent job. Would highly recommend this team to anyone.

Jermaine, Harpreet, and Gracie did excellent job upgrading my attic insulation. From the moment they arrived, they took great care to protect my home. They were very professional. After the job was finished, Jermaine showed me pictures of the completed work and explained what was done. Thank you!!

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.

The team of Jermaine, Harpreet and Gracie were very professional, knowledgeable and considerate. They did a great job without much noise or inconvenience.

This is my second time doing business with Great Northern Insulation and this company delivers not just a great product and service, but their staff treat you like a valued customer and always provide prompt responses to questions. They also have a great scheduling program which makes the customer experience easy peasy.
I big thank you to Taylor, Crystal and Alex.

Professional and exprienced team, they did a good job as per schedule and expectations. Also, it is a very helpful administration for supporting, arrangement, and coordination.

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

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.
