I called Mike to clean my grout he was at my home on time and ready to go. After they were finished in about an hour and a half I was a little disappointed my grout was not as clean as I thought it would be :( I have porcelain tile with very very light grout. Mike said it would look cleaner as it dried and it did. Mike was 200 less then Stanley steamer and I did not have to deal with all of the up selling Stanley steamer tries to do. Would I use this company again you bet. My tile is clean my grout is clean. I am happy with the job Mike did for me.
