Great Northern Insulation

Blanket job done beautifully by the installers. Thank you so much Stefano, Alex, and Jeffery. I would highly recommended these guys, very professional!

Thank you Great Northern Insulation! We have noticed an immediate difference in our warmth! It was a professional and positive experience from the beginning. We would like to Thank Harley for the initial inspection. Papy, Frank and Jeffery for the professional and respectful job that they did. We highly recommend this company for anyone looking to improve their home!

Recently we had our new house build insulated by Stephens Bordeleau from GNI. We can't say enough about his excellent work, extremely pleased and would recommend to everyone.

Recently had GNI add insulation to my R25 attic. The service from sales person to installer was excellent. The process from start to finish was quick, thorough and well priced. The installation crew were very courteous, efficient and clean. I would highly recommend GNI.Kudos!

Update: 2 no call no shows. Then refused to let me cancel the contract. Then broke my AC and did slightly below standard work. Then threatened me with double billing. Really the worst possible experience. I paid them and ran. You should just run.I paid for fast and good. I got neither. 2600$ for a wall 22' by 7 and a half high(with flame retardant). Total rip off. Here are some pics of the broken AC and the cavity not properly filled. It's supposed to be 4 inches R20 plus. The marker line in the pics is 4 inches exactly. It's not even 3 in places. Some of the foam is also the wrong color and feels very soft.P.S. I did all the prep. That's why it was done well. They didn't contact me again after they wrecked my AC except to demand payment and created a second false invoice to make me pay twice for the fire retardant.I got the message. I was hopeful the AC would survive but the coolant slowly leaked out. So add a 600$ repair to the already over priced job._______________________________________________________No call

I wish that all business were like this! After I contacted GNI the estimator, John promptly called back and arranged a visit. He arrived on time and listened to our problems to get a good understanding of what was required. He spent time evaluating our attic and then provided a detailed quote addressing our concerns. The insulation crew Soni and Jomor arrived on schedule. They reviewed the work order and made sure they understood the specific problem areas. They were very neat and polite. They never complained despite the extreme heat. In the afternoon they were forced to leave before completing the job for safety concerns( given the heat). I was promptly contacted by the scheduler to arrange for the team to return to complete the install. John came by to ensure that all was going well and that we were happy. And we are!A First Class operation - from the people that answer the phone, to the billing office, the estimator and installers.

Our home's attic insulation is done by the Great Northern Insulation. We very quite satisfied with how the work was done: quickly, properly, professionally. Before blowing in the cellulose insulator they demonstrated how the attic looks like and commented why everything is done the way, it was done. Good skillful team. We are very thankful.
