I was skeptical about using the services of a sealing company. In the past, I had always applied sealer to my decks and driveways and choosing to pay for sealing was a new experience for me. I have to say, I was not disappointed at all. Their patented sealer was unquestionably the best product on the market, by far. Once applied to my Limestone pool deck, the surface became basically stain resistant. In addition to the actual product itself, the entire staff was courteous, professional and very efficient. Thanks again for everything Ken. I will definitely use their services again.
