SB All Surface Cleaning & Polishing did a wonderful job! I have already given their number to several of my friends. They went up 950 feet of stone out in the back and blasted that, and they went and polished up all the marble I put in in the 80's in the kitchen and bathroom that had been ruined by grandchildren. Then they went and cleaned all my porcelain tiles outside and it was lovely. Their prices were just wonderful for everything I got done and when I need them, I will call them again. I have already recommended them to other people!
