Highly Recommend

“Extremely professional and hard working employees. We just had our driveway patched and sealed this week and it looks amazing. They did a wonderful job, slopped the asphalt so we do not get any puddles (rained for two days and no puddles). We are extremely happy with the work and highly recommend Black Diamond Asphalt.”
