Great Northern Insulation reviews (934)

Best company ever had. Thanks to Dave who visited last year and Mike this year to confirm what needs to be done. The crew came right on time, very very professional, they make sure that no mess will be left behind. Explained what will be done and how long it will take. It took almost 3 hours in and out. They cleaned the area with vacuum and make sure that surroundings are protected. Well done GNI! I'm very happy with the work and will definitely recommend to anyone who wants to do the Attic insulation. Thanks to Dave, Mike, Nick and the 3 member crew (I forgot the names). Stop wasting your time for searching and getting quotes from different companies. Just call GNI get the quote and get the job done .. its that simple!

I contacted GNI for pricing on foaming a roof over system on my clients cottage. I spoke with the salesman who quoted the job promptly after his site inspection. The office staff and scheduler handled the details of timing for the job which went off without a hitch. The installers were prompt and friendly and completed the job in a timely manner. Their cleanup was excellent and passed inspection with the building department, no problem. In comparison with other prices GNI was competitive and fair.

For our basement, we did R20 on the foundation walls and R24 in the Rim Joists. We excluded the mechanical/furnace room as we did not want to incur additional costs [from our general contractor- GC] for the existing batt insulation removal, framing, and then drywalling over the spray foam since you can not leave the spray foam exposed. It should be noted that GNI can remove existing insulation for you, but it will likely cost you more to use them for removal since their labour rate is likely higher than a regular GC. Our basement is about 950 sq ft in area, but the quote was based on linear feet (as were all our quotes for Spray foam). Hopefully providing you the sq footage will give you an idea of your expected costs. We selected the closed cell BASF (purple) Walltite Eco Polyurethane Spray foam. Alana C. was easy to deal with. She is the one the came on-site to do the quote. We had her come back an extra time after our general contractor completed the framing/electrical/plumbing as we had some concerns that there may be some areas that would not be accessible to GNI. We dealt with Nick in the back-office for scheduling the work appointment (1-day of work) and payment including 20% deposit. For the deposit, you also need to pay the HST on the 20% deposit at the time. The $3,395 costs noted is before HST. Both Alana/Nick were reasonable in answering questions. The one thing I didn't like is that I had emailed both at the same time asking about energy rebates available for us in the area. One replied saying there was none and another replied saying that there were rebates available. So it was confusing to get contrasting responses. The actual work was done reasonably well. My GC who does a lot of basements and has seen other spray foam Companies as well has no concerns with the quality of the work. Two younger guys came to do the spraying work. They did leave a bit of a mess. For example, 1) bits of broken off spray foam on the main floor inside the house even though they were only working in the basement; 2) a few spray foam pieces that I had to clean up from the front yard; 3) a couple of good-sized rocks left in the basement. No idea where the rocks came from but perhaps they use the rocks to keep some protective equipment in place. I had to throw these rocks out on garbage day; 4) the left the mesh screen off when the closed the basement window. The popped it off to bring equipment into the basement but never put the screen mesh back when they were done. Overall, I'm still happy with the work done.

The people at GNI know their field. Knowledgeable and kind sales staff and the two gentleman that gave to do the job were excellent. I had no concerns about leaving them alone in my house and they did such a great job! We have recommended this company to friends and family only after a week of having it done. Thanks team for a job well done!!

Following an energy audit to upgrade my 35 yr old home, I contacted Great Northern and was treated with utmost respect and care. The job was completed in a timely fashion by people who arrived on time, explained what they did and cleaned up after themselves. A wonderful experience all the way around-I wouldn't hesitate to recommend them!

Fabulous from start to finish. Professional and courteous and did exactly what I needed. I had both spray insulation and blow in put into my attic, each for different reasons. 2 visits with 2 crews. Everyone was punctual, professional and capable and in construction that's a tough thing to find. Price was reasonable and for spray in, I'd deal with no one else. It's important to have TRAINED crews doing the work.

After two unprofessional quotes I was delighted with Alana Cooper's initial appraisal and her written proposal. Tom and Brian J workmanship as well as Marilyn in the office's customer service was impressive. RSinger

my workshop needed insulation in hard to reach places and I was happy to find people who were hard working and committed to the task at hand. They worked through intense heat and a plague of mosquitos and did a great job!!! THANKS.

1400 square foot basement and the team was done inside a day. Clean, professional and safe - we would recommend GNI to anyone. From the initial quote all the way through to the job being completed, GNI did a fantastic job.

Very impressed with the service provided, they showed up on time, completed on time and team cleaned up before they left. Our project was a secondary suite in the basement of our rental property. I would use Great Northern Insulation for all my other insulation needs.
