Grout looks exactly as it did before cleaning. Talked to owner, Chris, and told him I was not happy, come and see the floors. He agreed, set up a time, did not show up, sent his workers. Flat out lied to me. Btw, I had cleaned a small portion of the grout on my hands and knees to prove it could have been done better, even though I am 70 yrs old. Sad.
