After cleaning, it is important to properly seal the grout and some tile. Your technician will give you more information on this process at the time of the initial estimate. Clear sealing will protect your grout from further collection of dirt, soil and most stains. For grout that has been damaged from age or improper cleaning methods, we recommend using a color sealer to completely recolor the grout and add the same protection from stains.
