Great Northern Insulation

Jeff and Shawn did an amazing job, very helpful and informative. Answered all my questions. Thanks guys, will highly recommend your company to family and friends. Will definitely use you in the future for the attic. Thanks again for a job well done

We recently had our garage insulated and can't believe the difference in garage temperature. They were here on time, did the job in a timely manner, cleaned up after and you woukd have never known they were here. Very pleased to say the least

Derek and Dave were absolutely awesome, explained the process, answered my questions and did an fantastic job. They even cleaned up before they left. I have no quams about recommending GNI. From beginning to end the service and quality were exceptional

Company was vary easy to work with and accommodating with scheduling dates and times. Answered all my questions without hesitation. Crew of Derek, Tom and Dave were very polite. They did a good clean up after the job was completed even as they were working late. Arrived about 3:20 pm and departed at 6:00 pm . My home is approximately 1300 sq feet , side entry raised bungalow.

We have a 1920s era 2.5 storey in Hamilton which we purchased earlier this year. The attic was unfinished and had zero insulation, which we REALLY noticed after the brutal summer of 2016. As a result, we had the GNI folks spray foam our attic cathedral ceiling, including the soffit/headers at the top of the second floor walls. We intend to finish the attic in the future, so this is our first and most important step in that process. We also had the guys spray our basement headers (where the first floor joists sit on the block foundation wall).

Everyone was pleasant to deal with along the way, from our sales rep Dave, to the sales coordinator Lisa, to the crew chief Jason, to the guys who did the work: Issac, Jake and Marvin. The guys did a great job with the basement headers and the attic, except there were a couple of soffit areas they had to come back to do. When I contacted GNI to get things sorted out, the guys came back within a week and touched up the job. I personally don't get too bent out of shape if things don't go exactly perfect the first time, as long as the company can remedy any issues in a reasonable way. These folks took care of it and did a good job, so I'm happy.

I would use GNI again and I would also recommend them.

I tendered a few quotes to spray foam our large attic in our older Victorian home. I was impressed by the knowledge of the salesperson, John, and his quote was the best one we received. The installers, Dave and Colin, were excellent and clearly knew their stuff. In speaking with one of them I learned that he had been with Great Northern for 7 years as an installer. There is no substitute for experience when it comes to installing spray foam. Both installers were professional, courteous, prompt, and thorough. They also cleaned up before they left. I would not hesitate to recommend this company for anyone who is looking for a quality spray foam insulation quote and installation.

Great job by these guys, they were clean and courteous. The crew was on time and did not waste any time completing the job. They answered all my questions and were very knowledgeable . I would recommend this company - price was on point
Job leader for the company was Reinier Bredeweg

The 2 workmen arrived at the appointed time , surveyed the site and promptly got their equipment out and set to work. Within a couple of hours , they were finished spraying the entire surface of the walls of the 25' x 40' crawl space . After cleaning up and packing their supplies , they left the area as clean as they found it .
If my first hydro bill for heating the crawl space area is any indication , the insulation will pay for itself in no time at all .
