After attempts to clean the grout ourselves, using every concoction known to man, we decoded to go with a professional cleaning service. We obtained three estimates from reputable companies. From the minute that “The Groutsmith” arrived at our home, their level of professionalism and customer service were obvious. The work they did can only be described as amazing!!! The entire floor looks like a brand new floor. They are professional, polite and extremely capable of cleaning tile floors. They answered every question and explained the process in great detail. We are extremely pleased and highly recommend The Groutsmith for your tile cleaning needs. I can be very picky about the quality of service, but I having nothing but praise for this company.
