I will give the company one star because the person I dealt with was pleasant. However, the work was very poorly done and expensive. The concrete came up roughly through the stain although there had been no wear and tear on the floor, the corners were left rugged and unfinished, work was done over a crack which was left, and black glue was left from the previous floor which gave the floor odd markings both black and white under the stain. The dealer took no responsiblity for the work and said it was a beautiful floor; I had others look at it and they were horrified by the workmanship and the cost. I have since had the floor tiled.
