Mark and Francine have completed two jobs for me in the past year, and they have done excellent fast work for us. Last year, they blasted paint off a patio at our rental home that had been painted grey twice in the past. The old paint was peeling noticeably, and repainting would have just postponed a permanent solution. It now, a year later, it looks like a nearly new concrete patio. Today they blasted an older painted flake garage floor in our oversized two car garage. This had been repaired several times, and continued to look bad by peeling. In addition, it is slippery and dangerous in wet or snowy weather. Today, they blasted it back to look like a nearly new concrete floor. It looks great! I highly recommend Francine and Mark! -Fred Rosa
