I appreciated the thoroughness and honesty that Greg from SB All Surface Cleaning and Polishing brought to his work. I hired them to do an acid clean of the grout for some public bathrooom showers as well as some extra regrouting and sealing that we decided needed to be done. Greg was very clear about what could and couldn't be accomplished and how the results would turn out, which he was exactly right about. I was pleased that everything turned out the way Greg said they would be. The actual guys who came out to do the job were also very polite, professional, and did just an outstanding job. I thought their prices were perfect and I would definitely use them again in the future.
