"Paramount showed earlier than the designated time. Which was just fine with us. They steam cleaned the affected area and scotch guarded the area as well. I happened to notice on the side of their van that they cleaned tile grout. They were willing to do it while they were here on my polished limestone bathroom and shower stall. The guy was friendly and professional and efficient!"
