Great Northern Insulation reviews (936)

**I write this review not to discourage others from using GNI, but to educate you to ask any potential company on the training they provide to their employees and to ensure the team that will be working on your home is experienced.** I had 4 spray foam companies quote me in January 2018. GNI was not the cheapest nor the most expensive - they were reasonable. In fact, their sales person, Alex K., was awesome and took the time to answer every question I had and did not push for the sale. He was open and honest and answered my many calls. He is the reason I choose GNI. In retrospect, that may have been a mistake - going with GNI. Based on the many deficiencies in workmanship by GNI, I will not consider them for future projects. NOTE: I am referring to the installation team, and not their Sales or Customer Service group. Unfortunately, one bad employee or group will reflect negatively on the entire company as GNI management is ultimately responsible for who they hire and the training they provide. Should the installers have taken their time and care, they could have avoided the obvious: - Voids in various area (basement headers, behind electrical outlets, low corners, skylight opening) - Cut electrical and security wires during trimming/cleaning The reason for the low star rating is not due to the voids, which is still a concern, but because of the cut electrical - major safety issue. Although GNI was very responsive and stated they would cover the cost to have the damage repaired and to have the voids refilled. This could have been completely avoided by a qualified installation team. I appreciate the quick response and GNI offering to cover the cost of the electrical repairs, but what they don't understand is that this caused a domino affect and delayed the completion of the renos since drywall had to be pushed back, and then other trades. The point is, there is no excuse for shady work like cutting wires. Absolutely not acceptable. I hope I am the only one that has experienced this issue, and I hope they have either terminated the install team that did the work or has provided them ample training. GNI, as you know - it takes years to gain a customer, but only minutes to lose one. You have lost my future business.

They were great, quote was quick instation guys were great! Can’t wait to have cooler/warmer house! Tom and Brian were great! Would recommend to friends and family for sure ! Thanks lori and steve

I'm a builder who just moved to Barrie from the Ottawa area. Great Norther Insulation was the only company out of 3 to call me back and give me a quote, John and Jefferson came to remove the insulation they did a great job. I look forward to working with GNI in the future.

Called GNI Barrie to top up / upgrade aging attic insulation to R60. Angelo promptly returned my call and came out the next morning to take measurements and provide price. Schedule was made and a week later Tom and Brian came to perform the work. These guys are pros and they know their job. They worked fast and clean and the attic is now a nice and thick blanket of fluffy insulation with moore vents to allow proper attic air flow. Thank you Angelo, Tom and Brian for a job well done.

I cannot think of enough superlatives to describe our recent experience with Great Northern Insulation. Everyone who assisted us with improving our insulation was friendly, knowledgeable, helpful and totally professional. We arranged with Lowes to have insulation added to our attic as part of the GreenON program. Within a few days I was contacted by Glenn, from Great Northern Insulation, who arranged to come and take measurements. Glenn was extremely helpful in showing us where we needed to upgrade our insulation and where it was adequate. He started the GreenOn application process and took the initial pictures. He made that part of the process extremely easy. The quoted price was excellent even without the GreenON rebate. Shortly after signing on with Glenn, Kim, from the customer eXperience team, contacted us to offer us some dates. Once again, she modelled all the attributes of Great Northern. When we had to go back and change the date she called us back quickly and worked with us to find another time. Exactly as scheduled, Nathan and his assistant Brandan, arrived and with total care for our home and completely professional service, they increased the level of insulation in the portion of the attic that was deficient. While the heat wave had broken, it must still have been incredibly hot in the attic and under all their protective clothing. When completed, they vacuumed up he entire area leaving no trace of the process. Nathan even showed us the after pictures to illustrate the new level of insulation we now had. This install was incredibly professional, easy and extremely positive. Great Northern Insulation is a wonderful company to choose to have work done in your home.

GNI recently upgraded our attic insulation to R60. Noticed immediate improvement in air con performance . Hopefully similar improvement in winter heating performance. Work was completed professionally and efficiently by Tom, Brian, and Andrew of GNI

The workers arrived on time, set about doing their jobs professionally, explained the process to me. They were competent, professional and enjoyable people to deal with. I am very pleased with the final outcome. I would recommend them to my family and friends should they need this service for their home(s).

Angelo came and quoted the job, very professional. Then I dealt with Nick to book the date of the job, again very professional and personal. Today John and Andrew arrived right at 8.30 am as scheduled. Both gentlemen introduced themselves with a handshake and proceeded to explain what would happen. Tarps and plastic was layed down for protection and they proceeded to begin the task at hand. My wife was keeping them hydrated on such a brutally hot day. In the end they vacuumed the floor, packed and were on their way. John and Andrew from Barrie were the most professional, polite and nicest service people we have ever dealt with. Your company can't buy advertising as good as them. I will always suggest Great Northern Insulation to family and friends. Thanks again John and Gail.

Great experience from start to finish. Matt Reesor was on time and was very professional and informative with regard to attic insulating. The team of installers also arrived as scheduled and did an excellent job. They too were knowledgeable and were very respectful of our home. Nothing was left uncleaned after the work. We are so happy with the work that was done. Our home is so much cooler. Highly recommend Great Northern Insulation!!!

I'm really happy with Great Northern Insulation. The team arrived on time, were courteous and friendly and did a fantastic job. They vacumed and cleaned everything including my stairs so you would never have known that they had been here. I also noticed a considerable temperature change in my upper level nd I'm so happy I chose this company to have this done. I should mention that this was done during an extreme heat wave so it could not have been easy for these guys.
