    I highly recommend Great Northern Insulation. They did a great job installing foam insulation at a reasonable price. We received a quote from another contractor that was much higher. The salesman/estimator (Eric) was very knowledgeable and helpful in ensuring that we understood the process and selected the right product. I would hire them again.

    had your company come in to spray foam and blow in attic insulation to a new garage which we just build. Your staff were there on time, pleasant, courteous and new what they were doing. Asked me to look over everything before they left, both levels were cleaned up and all garbage was removed. Would definitely recommend Great job

    From quote to completion of the job, very professional. Brendan and Keegan were polite and friendly. Explained exactly what they were going to do (which was as per the quote I had received from Mike the Sales Manager). Excellent work; I would recommend GNI to anyone who wants a worry-free job to be done in their home.

    I would like to leave a great review for your company. From Mike who did our quote to Jason who followed up and the two great installers ( I feel terrible I don't know their names). Everything about this purchase was positive. I cannot recommend Great Northern Insulation enough, particularly the Port Perry location. Quality of workmanship and product is A+! " Highly recommend! already have spread the word how amazing the experience was from start to finish

    We recently had our attic insulation removed and new insulation blown in by GNI. The entire process from initial quote to job completion was handled in a very professional manner. I would definitely recommend GNi.

    I got several quotes to increase the insulation level in my attic. Each quote was comparable; however I went with GNI because they had the best customer service. Once I submitted a request for a quote, I was contacted shortly after, a representative came to our home, and I received the quote in a very timely manner. Once the crew came to complete the work, they covered the floors, did the job very efficiently, and cleaned up at the end. Overall, an excellent job and great customer experience usi

    Great job right from the quoting process all the way to installation. Showed up on time and went straight to work. We have been going through a renovation and this company was one of the best. I would highly recommend this company to anyone.

    Excellent service from start to finish. Mike came in a did a quote and explained the process to us. Nick followed up with the scheduling and even got us moved to an earlier time then expected. Scott and Brady came in and did the insulation and did an excellent job! They answered all my questions and explained how things were done once again so we were all on the same page. Everyone we dealt with was courteous, professional and extremely efficient. Best price hands down!!
