It was a seamless operation performed by your staff. From the installers from the removal of the old insulation to the spray foam and to the final day of putting in the blown in insulation.

Friendly, courteous and knowledgeable of the job that was to be done.

I was present for the duration of the job and it was like hanging out with my buddies, joking around playing with my dog at breaks in the job.

Kristin from the office always answering my inquiries almost instantly.

Ryan after the first visit got the price down for me after we worked a different way to proceed with the job.

All in all a great company to do business!

Thanks again

We are very pleased with the spray foam job Great Northern completed in our home. The installer that came out and completed the job was friendly, professional and took the time to explain the process. He took care and pride in the work.
Thank you.

I wanted to comment on the work your guys did, foam spraying my kitchen walls last Friday. Firstly, they arrived on time (maybe 5 minutes early), then they asked if they needed to remove shoes before entering my home. They sized up the job, did prep work to cover windows, doors etc. They sprayed the foam, giving me at least 3 inches of depth, then cleaned up after themselves before saying goodbye. They were done in about 2 hours and did excellent work. I was very pleased with their work and would recommend you to others.
