Great Northern Insulation

My husband and I hired Great Northern Insulation to add insulation to our existing insulation in the attic of our house. The attic had an approximate R20 rating and upon completion we were told it was now R60. We were extremely pleased with the service we received. Bob and James arrived early and were very professional and pleasant. They immediately got to work, preparing the areas that would be affected. Both Bob and James completed the entire task quickly and efficiently, and after vacuuming and cleaning up the hallway and stairway, they explained everything that they had done in the attic.
My husband and I were very pleased with the entire experience and we would definitely recommend this company to others!
