Project Attic Insulation

Needed the garage attic insulated, called the company our builder used and they responded and completed the job with ease. Everything was quoted ahead of time and easily emailed and confirmed in a timely manner. The workers on site were on time and things were clean afterwards. My dogs are a good judge of people and they had no problem with Sean, Walter and Crajo(?) being in our house. If needed, we will use them again.

Just my kitchen

I was remodeling my kitchen and wanted it insulated properly. I phoned a few spray foam places in my area, but fortunately decided on Great Northern Insulation. The staff, from the original phone call to the work performed was amazing. They fit my small job in on time and did a great job. I can't say enough about this insulation and the people that work for Great Northern Insulation, but I will say THANK YOU

Insulation, spray and blown in

GNI did exactly what they said they would do and the work was done professionally by competent staff. They were also very clean. Now, our 1910 home is as well insulated as it possibly and reasonably can be. It feels more comfortable. We did have a before and after energy audit done that demonstrated that the work was effective. It's not just about cost saving, it's also about limiting energy consumption.

Attic Insulation

After receiving a recommendation from an energy auditor, I contracted for Great Northern Insulation to come to my home to upgrade my attic insulation to R60. We agreed on a date and time and the installation crew arrived as agreed. They spent approximately 1 1/2 hours from start to finish and when the work was done they cleaned up the work site. The crew was courteous and helpful to answer questions.

Install additional attic insulation

The estimator Matt was friendly and informative. I had another quote done but this was a better price and included baffelling and insulating the attic hatch.
The installers were a bit later arriving than the scheduler has said but it wasn't a big deal as I work from home anyway. Phil and Bill did a great job and didn't leave a mess to deal with.

Thanks for the great service!

19 Carolina Crescent

I live in a new house which had R50 I wanted to go to the next level of insulation. After contact GNI I was presented with a reasonable quote. GNI staff showed up did an amazing job and vacuumed their way out of the area worked in. The staff Craig and Sean were exceptionally polite and professional. I would recommend to my neighbours and family. Thanks GNI

Attic Insulation

Phil and Bill came on time as scheduled to blow in insulation in our attic. They were very professional and did the job quickly. They also did not leave any mess. We were quite pleased with the service and would definitely use this company again if their services were required.

Attic Insulation

Site inspection, administration, and interaction with the crew were all extremely pleasant. They were patient, explained things well, and were very personable. I enjoyed working with this team.

The work itself was efficient and they easily managed the physical space to get everything in place. They provided regular updates and took care while moving through the home.

My only concern was with clean-up. We have a toddler and I understand these kinds of jobs can be messy but if they could have left the room with the attic hatch, nearest hallway and stairs leading to the 2nd floor in better condition than they found it, that would have given us somewhat greater comfort. As it was, I had to conduct an extra cleaning just to be sure toddler didn't find anything on the ground and attempt to eat it. All in all, it wasn't a mess but helping out new parents would feel so good.

Thank you for taking the time to review us, We're thrilled to know you were happy with the service from start to finish. Thank you for the feed back about the clean up. Although we take pride in the fact we clean up our mess after we leave, We can understand the joys of having a new baby but yes, that everything does go in their mouths. We hope this extra cleaning wasn't too much of an inconvenience and I have shared you feed back with the team and office. It's feed back like this that allows up to change for the better!
