Very happy with the service! Had these guys do maintenance on the stained concrete floors in our house in McKinney. The floors were originally installed by the builder 9 years ago and the sealer was starting to flake in the walkways. We also had some fading of the stain in the areas where the sealer was coming off of the floor. They suggested a more durable sealer than the one the builder installed and our floors look pretty much as good as when we moved into the house.
