I chose Great Northern Insulation based on the positive feedback I read on the Homestar’s website. When I called to get a quote, an appointment was set up immediately. I had called two other insulation companies but one didn’t bother to respond, while the other didn’t respond until after Bill had come and gone.

Bill was extremely friendly and informative. When I received the quote it pretty much mirrored the cost the folks on Homestar’s had shared so I gave the go-ahead. Apparently there was a misunderstanding as to what work was to be completed once the installers arrived however, once I called Bill, he totally diffused the situation, and assured me all would be taken care of and at no extra charge. Imagine my great relief and surprise when he followed through within the week and made good on his promise. I am so impressed that I let everyone know, including friends on face book who they should hire should they need insulation.

Your installers were also very friendly and respectful of my home, putting down sheeting and ensuring everything was left in good order. They were polite, quick and efficient. Again, very impressed.

My total experience in dealing with Northern, from the office staff to the sales representative and finally, to the installers was top notch! I will not hesitate to recommend your services.

Thank you for your great service and professionalism!

Your sales rep Matt was great. He showed up when he said he would and went over things thoroughly regarding the quote. The installers were on time as well and installation was good for the most part. There was a bit of a hiccup with the bathroom vent but they did explain the situation to me and got things fixed up. The only issue I did have with them is that I found that they were not that careful when pulling the hose throughout the house as the doors and trim were scraped up and left a fair bit of insulation pieces on the floor in the house and outside after they left. Clean up could have been better. I had no issues with the office staff.

Alana the sales agent was great. I found her to be knowledgeable and helpful. I think she does a good job for your company. The only suggestion I have for her, is she might be a bit quicker on responding to calls/emails.

Installers were great. Don't know what they could have done to improve.

Value for money!

Matt was great to deal with as a sales rep. The install guys showed up a day earlier than I expected and cleaned up after themselves, so all was good there as well. I would recommend you to others.

The installation went smooth, and the installers did a good job at prepping before applying SF. My experience with Great Northern has been a positive one.

I attempted to contact some of your competitors, and found them unresponsive ( not returning calls etc. etc.) Mr. Barlow was good to deal with, his assurances on what to expect and the installation process were as described.

Overall, we are satisfied and would recommend this firm.

The guys were friendly, on time, explained everything and left without any mess or issues (nothing I've noticed anyhow). The only downside was the scheduling due to the local office admin quitting (or so I was told) and my order getting lost for a bit but that was taken care of quickly once we figured out what had happened. Other than that everything went great.

We are very happy with the job that your installers have done in the appartment. Everything passed code without a problem and we are now moving forward with drywall. Bill Barlow is another person that we were impressed with. He answered all our questions and even got us the paperwork that we needed for the inspector. Even at 9 pm. He had it to us in less than half an hour. We are very pleased with the service that your company has provided.

I will recommend your company to any friends or relatives that are looking to do sprayfoam installations. Very happy with your product and team.

I was very happy with everyone who I dealt with at Great Northern Insulation. I would give every single person a 10 out of 10 and I would not hesitate to recommend you to friends. My only comment would be the following… I had been given an installation arrival window of noon to 2pm. The installers did not arrive until after 3:30 pm. I understand that delays do happen however I would have appreciated a phone call or a text keeping me informed of the delay. When they did arrive though, they were wonderful young men who did a GREAT job!!!!

I am very pleased that I chose Great Northern Insulation for the work.
