AZ Tile & Grout SAVED my stone. I could NOT be happier with the PROMPT , professional and caring attention given to my stone. I had etched some Travertine stone wall art in my attempt to clean and beautify the stone. I had no idea how sensitive dry Travertine was. I was sure it was ruined. AZ Tile and Grout not only cleared the etching off of my stone, they enhanced the colors and made my wall art sculpture BETTER than when it was delivered. I am FOREVER grateful to this company. I would recommend them to EVERYONE after the amazing job they did for me.
