Derek Stanley, the owner of DS Asphalt, called me Saturday evening within 5 minutes of my requesting a quote online. He arrived early Sunday morning as scheduled and gave me a very reasonable price quote for the job. I had been seeking someone to seal my home driveway with oil-based sealer, which is not easy to find, as most companies now only use the water based sealer. Derek was prepared to do the work when he gave me the estimate, and he did! He took care in preparing the driveway, blowing and trimming, and put down tape to protect the edge of my stone walkway next to the driveway. He carefully applied the sealer, evenly and thoroughly, and blocked the driveway after the work was finished. The driveway looks terrific. Thank you, Derek for a quick response to my call and a great job!
