The previous owner had sealed and painted over the concrete and it was starting to flake and peel. Pressure washing was just not getting the job done. Mark gave me an estimate over the phone, came out within 1 week and had the job done in 2 days (1300 sqft). After work was complete, they did a thorough job of cleaning up as well. My concrete is bare now and ready for a new stain. Appreciate you!!
