I am not the best person to write on tile floors, as I am not an expert in the field of flooring. But I can tell you that these guys are the real deal. I had a problem with my upstairs bathroom floor – it was constantly wet and there was a huge hole. I talked to them, and they said they could fix it. I was a little hesitant, but I called them and they came out the next day. They fixed the floor, and it’s been perfect ever since.
