Ryan has been so helpful and willing to work with me in picking the right product, showing me samples, troubleshooting a residue issue that turned out to be smashed kitty litter particles and generally responding to everything that came during the floor sealing process, including fixing a mortar issue at my threshold that had nothing to do with the floor sealing. I am very pleased with the Stone-Lok sealer applied to my reclaimed blue stone floor. Great company customer satisfaction policy! I have used them many times through the years and I am always pleased with their work and people.
