"Clean and timely"

I recently called Dexterous Hot Mop to come waterproof our new shower in my home and wow were they absolutely on it! They answered their phones quickly. We set up an appointment the very next day, and they came right on time.  I immediately had some questions about the procedure and they educated me about the Hot Mop Shower Pan system. They also answered why they say it’s the best waterproofing for your shower and showed me. The finished product looked absolutely perfect and they did not leave any mess or marks behind. I without a doubt trust this company on their shower waterproofing! Great customer service and even better workmanship!
