Great Northern Insulation

Work with Great Northern on a couple of projects. Both personally and professionally. They are always very professional. From the sales and administration, to the crew on-site. Very impressive operation. I appreciate the hardwork and quality they deliver.

Great Northern Insulation was very helpful in regard to assisting me with my insulation needs in our new home. We needed help removing some old insulation to prepare for water-proofing in our basement. They did a great job with that with very little notice. They returned to spray foam our joists and then also added insulation to our attic to bring it up to R60. They were reasonably priced and the team that worked in our home was beyond all expectations in regard to friendliness and professional. Thank you!

About a month ago, I had the attic filled with cellulose insulation. The workers were on time, courteous, efficient and friendly.

Today, a crew arrived and insulated the basement of my 1917-built house. Once more, right on time, and excellent work with friendly service. All garbage was cleared away and I was left with a brand-new, insulated basement.

I am extremely pleased with your company's services, and won't hesitate to recommend you to friends and family who may need insulation.

Extremely impressed from beginning to end, with the work done by Great Northern Insulation. Everything went smoothly, Jeffrey, Zachary and Oneil were very polite and professional, wrapping everything in plastic prior to starting and cleaning all the overspray afterwards. What a great team. My only regret is that I wish I had known about this company prior to spray foaming my new home. Definitely recommend!

Really nice people to work with and the the pricing was fair. Some other contractors were giving crazy quotes. The workers that came in were really nice. The work was done in a timely manner

Richard was very understanding, and flexible as we worked out our quotes. The contractors that came in, were very informative and accommodating to our questions and requests. They were incredibly professional, and ensured that we were informed with the status of our house.

We’ve recently topped up our attic insulation. The service level that GNI provided us was nothing but exceptional. Starting with Matt providing the recommendation and estimates, to Nick and Sarah’s prompt reply to all my questions. On the day of the insulation, Connor, John and Will carried themselves with professionalism, friendliness and efficiency These three gentlemen even took the time to inform us what to look out for in the attic and how we can maintain it. One rarely finds such a level of service and competency these days, and GNI reminded us what a high standard service level is about. We will look no further than GNI for our next insulation needs. Thank you GNI!

The estimator was efficient and fully explained what was needed to meet various rebate program requirements. The employees were prompt and showed up on time. The day was getting hot and they continued to work at this job without interruption until completion. Thanks for a job well done!

We had our attic insulated this morning. We are very pleased with the amount that was blown in.

Your employees Brendan & Tiffany were very professional and polite.

We went through the Greesaver program.

The workers were courteous and cleaned up after installation. We appreciated their professionalism and the fact that they did not hesitate to answer questions. We would use Great Northern Insulation again.
