I was referred to Dan by my realtor after moving into my home and discovering that the "brown" tile throughout the whole house was covered in grime (thanks, previous owners!). Dan and his crew came out and did an amazing job. WORTH.EVERY.PENNY! Not only was the floor so clean you could eat off of it, I was able to change the grout color to a lighter tone that was a better match to the tile than what was originally selected and they added a seal to keep the grout from getting so filthy again (as it turns out, "grime" is not a color people, LOL).
