Great Northern Insulation

When I call for a quote from Great Northern Insulation they returned my call the next day. A day later Mike came out to see the home gave me a quote. I scheduled the job. On the day the work was to be done the guys were here on time. They were friendly, polite and professional. Before leaving my home they cleaned up not only in the house but my driveway as well. GREAT JOB GUYS. I certainly will recommend Great Northern Insulation to all my family and friends.

This is my second time using Great Northern, as I had them first insulate above my garage. I find their work to be very thorough and professional. They were also very good at cleaning up afterwards. I wanted my attic to be R60 after the recent colds winters.

After using Great Northern for a new custom home that I built 3 years ago, they were the first to call for spray foam in a basement apartment in one of my rental properties. Their quote was not the lowest, but it was competitive and knowing the quality to expect from them was definitely a plus. They met my timeline with no issues and the quality of work was excellent, as expected. Good people throughout the organization helps to make everything go smoothly.

Did a renovation of our kitchen and living room removed the claiming and all the insulation. Got 3 quotes and GNI was not the cheapest or most expencince. From the start they where very professional and curtious. The workers showmed my everything they were doing and explained it to me. Very clean and professional.
I would you use them again and recommend them to all of my friends.

We would and have happily, recommended GNI. Nick was great to deal with. Angelo was very helpful in assisting us to be prepared to meet our install dates.
Our installers; Clayton, Will and Derek were very knowledgable, professional and personable.

Thank you, GNI. Our new home was cozy and warm just as the cold weather hit!!!!

GNI was on time and on budget. Two service technicians arrived and surveyed the work needed and determined the best way to blow insulation into our attic. Got the attic insulated in no time, with no mess. Recommend this company.

Dave and Kyle recently completed the spray foam of my full basement in the St. Catharines' area. The installation started as scheduled and took about 4 hours. Kyle was very receptive to my list of potential issues and ensured before departing that they were addressed to my satisfaction. The team minimized any over-spray and the basement was left clean. The work was performed efficiently. I also acknowledge the pre-installation visit by Eric (production supervisor). Eric was instrumental in arranging the spraying of rim joists prior to the full basement install. Without Eric's early intervention, the final result would have been less than optimal since accessing the rim joists once the stud walls were fastened in place would have been very difficult. I am very thankful for this.

Great experience and extremely happy with the service. From the initial conversation to the installation, everyone we dealt with was professional and friendly. The guys explained everything they were going to do, including how to deal with a couple of tight spot. The room feels warmer already. Thanks

Just had the lower overhang of our house insulated.
The crew showed up on time and did an excellent job.
Our floors are much warmer now!
We would definitely recommend using this company.

Highly recommend this company! They were very quick and did a great job. They were very friendly and cleaned up after themselves. They were also very quiet, my 4 month old slept through it all! Definitely recommend them, did a wonderful job!
