1 I know what the structural and installation requirements are for all the ceramic tile, glass, marble, and stone products sold for both walls and floors. We also offer floor tile and grout restoration taking an old dirty tile floor, and making it look new again. I offer a free in-home 5 minute demonstration. The other Tile/Grout restoration companies do not aggressively agitate the grout first to ensure all dirt is completely removed from the grout joint before the wash and extraction stage-I do.
