Al’s expertise and knowledge of products, as well as his architectural background were of enormous value throughout his work with us. He helped clarify and describe each step along the way, often suggesting several ways of achieving results, outlining the costs and benefits of each. He was open to suggestions from us as well. He was always respectful of our needs, and the work was done in the least intrusive way possible. His work is first-class and he is extremely attentive to detail. We are very happy with the finished product.
