Professionally sealing your driveway every 2 or 3 years will help preserve your driveway for about 20 years. Also improving the appearance of your home.
"My driveway is old and tired - and really looked horrible. I was almost ready to replace it but decided to seal it one more time. We learned that Jason is in this business and gave him a call. Jason's estimate was fair and we agreed to do it. Jason took the time to prepare the surface well! And the result exceeded my expectations. I'd recommend Black Diamond Sealcoating to anyone needing a fresh coat of sealant, providing a remarkably refreshed appearance! Thank you Jason!"

"It’s all about the prep work that made the finished driveway shine. Our driveway was in very poor shape from years of neglect and Black Diamond Sealcoating made the effort to fill all the cracks, and then the final seal coating was completed on day two. Now our finished driveway looks totally brand new! Fair pricing. Right on execution! Thank you Jason!"
