I can say that I had my heart set on stucco and nobody could change my mind. They provided addresses for me and I went around and looked at other homes and after I saw the product that they sell I decided to go with the siding. I am very happy with the way my home looks. It really has curb appeal. I have gotten a lot of comments from neighbors and people going by commenting on the color. The neighbors have commented on how the quality looks.
