Had our driveway redone and looks amazing. He was easy to communicate with, sent a reminder text the day before, and was on time. Price was great in comparison to other companies and overall we are completely satisfied!

Hired Denn’s Sealcoating for my driveway. He was friendly and professional and gave advice about sealing the driveway cracks. He came on time and did a fantastic job. My neighbor gave a compliment on the good job done. Reasonably priced.

Very impressed with how fast Gary responded to my online request for a quote. Within an hour I received a call and he was at the door shortly. We discussed the job and agreed on the terms. We had a professionally sealed driveway by the end of the hour. I am so impressed on how quickly and smoothly the job was completed. On top of all that it was done very reasonably. I would highly recommend him in any asphalt sealing need. Keep up the excellent work! Jay
