By design tile is a very porous surface. Microscopic openings within its seal allow for dirt, bacteria, and odors to settle in, discolor and then even begin to separate this composited material. Now its likely that theses problems won't happen over night, however, through daily foot traffic, the speeding of these conditions are inevitable. For theses reasons we've found our commercial tile & grout cleaning service to be much more beneficial when scheduled progressively throughout the year. At every service our technicians follow a systematic formula to achieve the highest, most consistent and measurable, results possible.
