Tile floors will eventually develop traffic patterns, much like carpeted walkways, with discoloration in the grout joints. Grout Restoration Works will apply a solution to your floor that is designed to pull dirt out of the pores of grout joints. We then use our advanced steam vapor cleaning process to eliminate traffic patters in your grout. Once your floor has been cleaned and rinsed, a clear, penetrating sealer is applied to protect your grout joints from future discoloration.
