What a First Class Organization!

After getting 3 other quotes, I met Matt from GNI. Matt was the first person that talked about what's involved from start to finish (from covering everything to leaving everything else as you found it). I was hopeful that his quote would be comparable, because I knew this was the company I wanted to proceed with. The people in scheduling were just as professional. Every call and every communication timed well. When we had to change the date...there was absolutely no problem. The crew that came were fantastic. I felt like they would do the job that we hoped would be done, protecting the exposed beams with cardboard. GREAT JOB ALL AROUND! Kudos to the management at GNI for creating a culture that creates such a well rounded team and processes!

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!

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.
