    Excellent job. Jeff & Brendan arrived on time, worked quickly, offered to help move some of my furniture and cleaned up after themselves after the job was done. Highly recommend this company.

    We found Jeff and Brendan to be both friendly and professional.They laid plastic down throughout the house to keep dust to a minimum and cleaned up after themselves. They were also quite thorough. I would recommend them to any of my friends or family

    Workers came in put a lot of insulation and were here for over an hour but did a thorough job and left the place spotless. Highly professional and recommend them.

    Matt and Ryan were informative and patient with my questions and both crews; attic and basement, were courteous, quick and didn't leave a mess behind. When there was a small issue in the basement Ryan promptly assessed it and a crew came back and corrected it the same day - very impressed! All my interactions with the office staff were also positive. I`m quite pleased with the service, results, scheduling and overall price. I wouldn't hesitate recommending GNI to family or friends.
