Great Northern Insulation reviews (934)

Your guys doing the blown-in insulation did an equally as good job as your crew who did the spray foam insulation a few weeks ago at my home in Amherstburg..

My husband was super impressed with the guys that came to do the work. They were very professional and courteous. They took the time to show him what had been done and explain everything. We will be sure to refer you to anyone who asks. Thanks again.

We recently had Great Northern Insulation come into our home and they spray foamed our crawlspace, everything was done perfectly and we were very satisfies with you customer service. Thank You

Your guys did an excellent job and I'm very pleased with the results. They took extra care to make sure the spray didn't cling to the PT posts and surrounding siding as well as the crushed stone ground. Job well done!

I recently had my 2300 sq. ft.bungalow home reinsulated by Great Northern Insulation, The crew members who completed the work were very polite and well mannered and did a great job!

Right from the start we were pleased with the service. Araon was our salesperson and he worked with us, so that we could get the work done within our budget and explained what would be done. Kristy in the appointment office was wonderful at working around our schdule and the guys that came and did the work were professional and arrived on time and cleaned up before they left. I would without hesitation recommend this company. Our basement is so warm now that we actually have to cover some of the heating vents. Great job by all

We received several quotes for our attic insulation top up. The home is a 1950's bungalow so we were in desperate need of an attic insulation update. We chose Great Northern and were very pleased with the efficient application. The job was completed on time in under 4 hours with no mess inside the home. We would recommend Great northern!

The house we purchased in Mississauga had a poor layer of insulating stuff. I've found "Great Northern Insulation" company in internet. Mike came at the same day I called, made the estimation and scheduled the date of work. All was done exactly as promised, quickly and with the excellent quality. Now I'm paying for heat significantly less than before. Good work, guys!

I had Great Northern Insulation out to my house to spray foam my Laundry room and a basement bedroom! The brothers were on time very polite and courteous! I explained what i wanted they made some suggestions that improved upon my needs! The job was done professionally and the basement left clean. Very happy and would recommend them to anyone! I feel i got a good quality job done for a fair price thanks again!!

Everyone was very courteous and polite and friendly. The job itself was well done in the end. However, there seems to be a lot of miscommunication in their office. We got a bit of conflicting information. We booked our foam insulation more than a month in advance. I spoke to Jason the scheduler. On the day of the foaming, the insulators told us that the "second crew" would have to come out a few days later. Maybe we were naive but it was never explained to us that the process would take multiple appointments. There was a bit of panic on our end thinking we had to clear out the pets and ourselves for another toxic installation. Luckily the thermal barrier is non toxic. But we were not happy that this was never explicitly explained to us. The installation was on a Friday (my dad took a vacation day to stay at the house, with a respirator, while they did their work). The next Tuesday I had a call from accounting asking for payment for the foam and thermal barrier. I told them the thermal barrier hasn't even been done yet and I was waiting on a call to schedule that. I was told they do not work on weekends. So I booked them for the next day to come at 7:30 am. I usually leave for work at 7:30 but told work I would be a little late (I was originally told that the thermal barrier would take "maybe an hour"). Then later I was told it would take 3 hours but that this was "high balling" it. 7:30 rolls around and no one is at my door. I called their office at 7:45. The scheduler called me back and said that the crew would be an hour late because they had to load a new truck. I was a bit upset that they didn't bother to call me to tell me that they would be late, instead I had to initiate the call. So they arrived at 8:30 and the crew was very nice and they did their work but of course weren't done until after 11am. There was also conflicting information between the crew and our sales guy as to what needed to be done in the crawl spaces. By this point I had missed half a day of work. Good product and pretty nice people, but they are lacking in customer service skills and I just really think they need more communication within their office.
