Kudos to Bob Giammarco, at Sentinel Safe Floors, for making our foyer tiles safer. Bob was very professional and took the time necessary to make sure the job was done right. What was once a very slippery floor now measures 3 times better on his slip meter. While he was at it, he was also able to lay down a slip-resistant solution on our basement stairs. Bob is very accommodating and reasonable and I would recommend him for any surface, that you feel could be a potential hazard for slipping.
