A neighbour was getting attic insulation from GNI and I called the company to get a quote. We also had other companies give us quotes. Mike dropped by a couple of days later and frankly was an amazing person to deal with. He was very polite, professional and pointed out things that the other companies did not. We were also lucky because when setting up a date for the insulation they had some cancellations and were able to fit us in. The two men who showed up were also very professional and polite. I'm sorry I don't remember their names. They put down drop sheets, kept things very clean and vacuumed up everything at the end. All in all, we were very pleased and would definitely recommend GNI.
