Great Northern Insulation

This company is superb. Very professional from quotation to scheduling to installation. The installation team, Phil and Tom, arrived on time, were happy, friendly and professional and left the house as clean as before the job. I definitely recommend this company.

I had 2 employees, Will and Connor, do the insulation job today.
They were on time, professional, neat and kept my home clean throughout the process. Excellent work all around doing a tough job on a hot day. I would easily recommend these guys to anyone needing this work.
Very good company to work with

Crew arrived on time on Friday of a long weekend. Derek and Troy did a great job of keeping the work site clean which I really appreciated as we had just had new carpet installed throughout. And we also got a quick lesson on R value and the install process. Highly recommend this crew. Thanks for a great job!!

We had a great experience with Great Northern Insulation. They were quick at replying to messages and arrived on time both days. Mike was very friendly and helpful. Would recommend!

Special thanks to the crew from GNI. Tom and Brian were very professional and cleaned up after the job was done. They also took the time and answered my questions. Well done.

When we purchased our home we were told by the home inspector that we would need to add insulation in the attic, not relizing that a home built 20 years ago could be so far from code today. We had roughly 8" of insulation our a/c would run non stop day night. We had GNI come in and add an additional 16 inchs on top of what we had and what a difference it makes a/c finally cycles likes its suppossed to and the house is more comfortable then ever. GNI was very clean and prompt job well done and cheaper then another quote we had gotten. Definitely recommend GNI.

Your guys said they would be here between 12 and 2. They arrived right at 12 which was great for me not having to wait around. They set up the tarps wherever they where going to be and protected everything in the bedroom where the attic is in the closet. They informed me of what they would be doing and approximately how much time it would take. They vaccumed up after themselves, so the house was just as it was when they came in.Tom, Sal and Troy were friendly and professional . All in alla great experience.
