Great Northern Insulation

GNI did a very clean efficient job in our complex. They insulated all the attics, no one complained and they cleaned up after the job. We will know better as a/c season approaches and than again in winter when we get our heating bill. Don't know the cost

The team of Derek, Drew, Brian P. and Tom did a tremendous job with my insulation. It's always easier to give a high customer service grade when everything flows without a challenge. However, when things do not go as smoothly as planned, it's at that time where one sees the real customer service. They exceeded my expectations.

There were some equipment challenges which the team addressed immediately, including vaccuming the front lawn. As an aside, the front lawn hasn't looked this good in years.

They explained any procedures that were being done so that I would be informed. Their work is top-notch, and they were thorough in cleaning once each day's work was done.

Therefore, I heartily recommend Great Northern Insulation for your insulation needs.

Just have my attic insulation upgrade to R60. They finished the project in around 3 hours. I am not a professional but what they impress me most is that they vacuum working area neat and clean after we done the job, they use a plastic to wrap my carpet before the project. Very friendly and polite.

Derek and Drew and Nick were fabulous!!!Derek and Drew even swept up the floor!! Very friendly and approachable! I would highly recommend all three of these men and your company! Thanks to Gary too ! Thank you all so much!! Richard was great too!

The 3 guys that came, Tom, Brian and Sal did an amazing job (from start to finish), they were very professional , knowledgable and friendly. Took great care to protect carpeting and other fixtures in home. Cleaned up well afterwards. They work well together and are definately an asset to the company.

Tom and Phil came today to install Loosefill Cellulose Insulation to our home. Prompt arrival, knowledgeable and professional. The company was recommended to us as the best around for quality, workmanship and price. All great service from my first contact with their office, visit from sales rep Bill to the completion of the work today. Can definitely recommend Great Northern Insulation.

I was very fortunate to have Great Northern Insulation come to do Insulation and Weatherization work at my home through an initiative of Union Gas. Everything from establishing my needs (house built 1975);
making sure I understood exactly what the jobs entailed to the actual installation of insulation in my attic, caulking my windows, and doing insulation in the crawlspace was absolutely first rate, Derek and Bill were on time, courteous, friendly and the hardest working guys in the business, I'm sure!!! Thanks Great Northern Insulation...can't wait to see my heating bills go down.

Great Northern Insulation was prompt and efficient. They insulated the upper story of our garage in an hour and a half. The staff was courteous and answered all of our questions. The work site was left tidy

Derek and Brandon were the most polite and well manner people. Explain step by step details. They continue even in the pouring rain. They said the job must be done.

they upgraded the insulation on my attic. the technicians were friendly and courteous. they took care in assuring that all the floor was covered and they even put a plastic cover over my bed (the attic entrance is in the main bedroom).
Based on the service that i received, I would recommend them.
