“Jeff and the crew at Black Diamond Sealcoating did an amazing job on my extensive driveway. They were on time with their service, very quality oriented, and went above and beyond my expectations. We had an unexpected thunder storm during installation that washed out part of the sealer. They came back and repaired this area ASAP without me even asking about it.”
