    We had a great experience with GNI from beginning to end. Bill was very helpful and knowledgable and was always quick to answer any of my emails or phone calls. Jason made scheduling easy, Marilyn in the office was so pleasant to deal with, and the crew was very professional. This was our first BIG renovation on our house, and the staff at GNI, made the whole process smooth. We couldn't be happier and wouldn't hesitate to recommend.
