Mark was a great find and a top top guy. Mark came to my rescue when I accidently walked glue across a newly laid bamboo floor in our kitchen / dining room. The glue etched into the bamboo which clearly stated from the manufacture should not be sanded. Faced with ripping up the new floor, Mark took it upon himself to research how to repair the floor. He used a new to market product, spent time testing it and returned multiple times to check the floor. He truly cared! When Mark left we had a floor that was back to looking like brand new. I have used many trades man over the years and this is the only one in which I have provided a review for! Mark is exceptional.
