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.
