Nick (owner sharper image) did an excellent job on my Engineered floor, there was very less wood to work with on the floor, but Nick with his high End machinery made it possible. He not only sanded to perfection but before staining the floor he gave us different choices by staining small area behind the stove with different color and that helped us In choosing the right stain. We were glad we used his services and would recomment 100% to anyone.
