Attic Insulation

Insulation review in Ottawa

The company won our bid with competitive pricing and scheduled the job fairly quickly. With all the home renovation delays it was refreshing to have the work done within just over a month of the initial quote. On the day the team was quick and clean. they updated me on what they were doing and kept to themselves. Thanks GNI!

Job well done

Toronto

GNI showed up on time and did a great job insulating our house. In particular they went the extra mile spraying the headers in the attic which were a big source of heat loss. I highly recommend them!

Attic Insulation Upgrade

Insulation review in Toronto

Our attic insulation upgrade was completed as per their estimate. They arrived a week earlier due to a last minute cancellation. Work was completed as advised, within a few hours. They left our house after cleaning up all residual materials, drop sheets were utilized and used properly. We are very satisfied with the work.

Ryan and his crew did a very good job at installing batt insulation and vapor barrier throughout the house. Thoroughly cleaned up before leaving site. Great customer service as well, always letting me know proactively what was going on and what the plan was.

Don’t recommend. They rush the job, and caused $600 in damage

Fire & Water Damage Restoration review in Toronto

Great Northern insulation rushed the job, and caused $600 in damage. I felt sick to my stomach after seeing their work. It took me two weeks to cut back the amount they oversprayed on my walls. They sprayed foam over my outlets, sprayed foam into my ducts, and sprayed too much product behind ducts causing them to bend. They sent a second crew to fix some areas, but they left large gaps without foam. Was not the prettiest job by any means
