The key to a healthy surface is healthy grout! Tiles may last forever, grout does not! Grout, the stuff between the tiles, is porous and absorbs spills, dirt, and grime like a sponge. If not cared for, the grout will become stained and damaged and will eventually need to be replaced. The Grout Doctor® specializes in grout, tile, and stone care for your home or commercial project. We’re a nationwide company, but locally owned and operated by professionals with extensive training.
