I am satisfied with the attic insulation work performed by Great Northern Insulation. Before estimate for the job was given, there was thorough examination of the attic condition to establish what needs to be done before blowing insulation. The staff during the estimation process and on the day the insulation was blown very courteous efficient and knowledgeable. I have already recommended your services to a neighbor.

Thanking you

The crew who came to do our insulation job were efficient, tidy and did an excellent job. We appreciated the fact that this job was taken care of expeditiously and in the same manner as had our previous insulation job in 2014. Should we require additional insulation, Great Northern is at the top of our go to list.

My experience with great northern insulation was great. I would definitely use your services again and recommend GNI.

The sales representative, Aaron, was friendly, knowledgeable, and answered my many questions by email. After the instillation he came by to inspect the work and see if I had any concerns.

The installers were very professional as arrived on time, answered my questions and did a good job cleaning up .

Finally, scheduling was very easy and flexible. I had to reschedule once as I was not ready for the insulation and rescheduling was no problem..

Thanks,

everything was great. Your installers were terrific. They were early, which was good as I was not late for work and went over everything with me and were in the process of covering everything in plastic when I left. I look forward to working with your company again when I insulate the other half of my upstairs. Thank you

Insulation review in Toronto

GNI came on time for the initial visit and gave an honest opinion on what needs to be done. They were the only ones to actually crawl into the attic to inspect. They did what they promised and did an excellent job. Would definitely recommend them.

What could this company do to improve their services?
Any advice to offer fellow homeowners facing a similar project?
