Great Northern Insulation

We renovated our basement and needed to insulate the concrete foundation. We called GNI, there was great service as far as time it took to get is a quote. The team was accomodating with the dates so we went ahead. Great work, very happy.

Was very pleased from start to finish. From online inquiry to on site inspection and quote (by John) to day of installation (by Phil and Tom). All crew members were professional, clean and courteous. Very pleased with care of installation and clean up. Thank you.

I Can say , a very efficient and professional company to deal with, prompt, sevice providers where knowledgable on the work they where gong to do, provided advice on attaining better air circulation in attic, cleaned up after work was done. And I would highly recommend them to anyone I talk to. regards tim

We recently hired Great Northern Insulation to insulate an attic. The workers were on time and very professional. They were careful not to damage the freshly painted walls and did an excellent job cleaning up after the job.

Booking and getting a quote was fast and easy as was scheduling. Work occurred sooner than expected and payment was also a breeze. Used a combination of phone and online. Guys onsite were Tom and Brian and were punctual, polite, and clean. Dealt with parking issues like champs!

Our attic is a loft and attic in one, GNI came in with a combo of spray foam, added vents and topped up insulation. Great crew and service and now my home is much more efficient. Appreciate the work and the clean-up.

Very fast and professional did a great job where very respectful of my house took there boots off when they came in. I am very picky when I work and after they left I had a really good look at what they had done in my basement and I was very impressed with the quality of work out of Brian Jesse and Joel great guys would highly recommend them AAA+

Great Northern came in at a good price. They were very helpful and their work was completed on time. They cleaned up so very little mess left for me. Workers were very pleasant and helpful. All around great service.

The whole experience was excellent. I called with an very narrow time frame and Angelo was at our house the next day and completed the quote that same day. Tom, Brian and Sal arrived at our house on time and were extremely courteous, professional and knowledgable. They took time to explain and answer our questions thoroughly. At the end they cleaned up, vacuumed and you wouldn't even know they had been here. Good job guys! Would not hesitate to recommend Great Northern Insulation.

Tom and Brian arrived exactly on time. They were polite asked if I had any questions and completed the job in 1 1/2 hrs. I was very impressed. Highly recommend them.
