I’ve used the same CertaPro sales guy for 12 or 15 years. Exterior and interior jobs. Each time I received multiple quotes and they were always middle price, so kept using them based on previous experience and satisfaction. Our new house they did the polyaspartic floors in garage, but my wife actually did the kids room, bathroom, laundry room and pantry. She knocked those out in a day and a half and it only cost me a couple trips to Sherwin Williams. Their site runs specials all the time and cost came out way cheaper than going to HD or Lowes.
