Insulation Improvement

As part of a reno, I paid to have some required insulation upgrades done. It was to be inspected with a follow up energy audit to allow a rebate. The work was not done suitably to meet the audit requirements. Had there not been an audit completed, I would have no idea that the work was done poorly. Also, a mess was left upstairs and in the garage. Disappointing as a consumer because I'm not auditing the quality of an insulation job. Apparently I should, because in the one and only case I've used GNI they have failed. They came to fix the problem with another crew and a supervisor to ensure it was done correctly. I work out of town, so I've had to adjust my schedule for a return visit by GNI and by the Energy audit group. GNI could only guarantee they'd be there between 1-3pm?? After they screwed up. In my mind GNI failed big time overall.

Trailer rebuild for book store

We bought an old office trailer to start a book store, ee gutted it and were looking gor solutions to insulate it to protect our books. We contacted Lowe's for the job and Great Northern Insulation was sent out to quote the job. The team was awesome, we had to postpone the job a few times as we were rebuilding the sub-subfloor and ran into trouble. Kim in the office was great, answered questions and emails promptly and never gave me a hard time. Tidsy the job was done. The team arrived on time and did a great job, thanks for making this this such a stress free solution for our needs!

Insulation Attic

Installers were right on time, careful to explain the job and were very good at keeping things clean. The job took a little under two hours and they cleaned up very well when done. Job well done!

Removal and installation

We had a significant issue in our attic which required existing installation to be removed and new spray foam and insulation to be installed. The work also required cooperation with separate roofing and mold abatement companies. Throughout the process we received fantastic advice and service from GNI. We dealt with a number of their service staff and they were all polite, professional and respectful of our home. I would recommend GNI to anyone - they were amazing.
