I own a small business and when I spoke to the salesman, I told him I needed it done in one day, which I realize is completely unreasonable. The salesman was sympathetic, and the crew showed up on Monday morning and had the job completely done and cleaned up. It was perfect.
The installation crew was excellent. They worked very hard and were very good guys.
I was really happy with the different layers of quality that was involved. It's a really long-lasting package from Owens Corning!
