I had a skating rink after sealing the travertine pavers around my pool. I looked everywhere on the internet for possible solutions and came across  National Sealing. I spoke with a very knowledgeable Kenny who explained to me my options. After in depth research on their work at different locations in the US and abroad I decided to give it a try. Mark arrived on time for the service appointment and it was fun chatting with him while he worked. Three pool parties later with no less than five kids running around I feel safe to say I made the best decision for everyone’s safety. My wife and I are very happy with the outcome. Kenny and Mark, thank you for your very affordable and effective product and for making  business with you a pleasurable experience.
