I sought the services of Great Northern by recommendation from my HVac provider. The only complaint I have is that it was difficult getting an appointment. In my opinion, this is most likely a result of two factors; trying to get the service in the busy fall season and they are super busy because they do great work. Jason, was the salesman that gave me the quote. He was informative, helpful and honest. It was an easy sign up. Steve did the scheduling and he was very accommodating. Sarah, guided me through the process of payment. The work was done on November 17, 2021 and my apologies but I can't remember the installers names; I will say that they were efficient and left the home clean and tidy. As for the product, I am not in the business but from the appearance it looks like every crevice is sealed nicely. It already feels much warmer and dryer. Thank you GNI for spray foaming my basement. I can now finish my renovation and start enjoying this awesome space. I highly recommend Great Northern for spray foam insulation. Paul

Great job! Very satisfied! Crew showed up, were very informative about the process and then proceeded to protect everything from overspray.
Job went smoothly due to the organization that the spray crew used throughout the job.
Neat, friendly and courteous crew.
No complaints about their work.
Thank GNI for help with our project!

We just had our house insulated by Northern Insulation and we couldn't be happier.Tiffany and Sabrina were always on time, very friendly and left the place clean every night. I would differently recommend Northern Insulation and especially these two great women.

Two female employees came in, worked quickly and cleaned up. No fuss or problems. Highly recommended for any upgrades or house improvements in a private home. Can almost feel the warmth and haven't had to use the furnace yet.

Enjoyed the experience from start to finish. Great company. The are prompt, respectful and polite. Very good work from 2 Chris’s and Matt.
I would recommend them without hesitation.

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
