Travertine needs help! Dirty travertine floor needs a good clean and seal. Travertine stone floors can lose their luster to every day dirt and grime. Pressure washing was the first step in this travertine clean process. Once the floor is thoroughly cleaned, touch ups are made to areas where the stone might need a little help. Sealing is the last step to insure your travertine is clean and protected. This is now a great looking floor!
