I contracted Great Northern to insulate my attic from an R22 to R50. I had three other companies quote me. Prices range was much higher with al of the additional costs for new vents. Great northern price was 25% lower and they told me that there was no need to change vents nor any repairs was necessary. Thier price was exactly as my own calculations....I am an Engineer. Their guys were professional, courteous and considerate. Unknown to the guy in the attic, I was behind him looking at the job he was doing, Checking the height and layer of the job and was pleased to see it was being done to my expectations. I could not find anything to complain about even though I was looking for a flaw. Great job, I would recommend this company.
