Why Seal Coat Your Driveway?

Before Sealcoating
After Sealcoating
Seal Coating prevents oxidation. Asphalt pavement begins to deteriorate almost as soon as it is paved. As the pavement is exposed to oxygen, the asphalt binder (tar) hardens. This hardening results in a brittle surface that eventually cracks. Cracks in the pavement enable oxygen and rainwater to penetrate the pavement, often into the sub base, weakening it and reducing the pavement’s strength. Seal Coating protects the surface and fills surface voids, reducing pavement’s exposure to oxygen and water and extending pavement life. Seal Coating enhances pavement appearance and eases maintenance. Seal Coating brings back the dark black color of the original pavement, making it look and wear like new. Because seal coat fills surface voids, a seal coated surface is much smoother, which is easier to sweep, shovel, and wash.

Our Customers Love Us!


  • I sealed my driveway before selling my house for some instant curb appeal. I had no idea the difference that it would make. I just wish that I had done it earlier to enjoy it more myself! Lang’s Seal Coating was very easy to work with and very reasonable pricing. Thank you!

  • Three years ago, I hired a company to seal coat my driveway. They used a spray that they told me would last for several years. Within 6 months, my driveway was back to looking gray, like before they sprayed. So, I tried Lang’s Seal Coating and am impressed that after two years, my driveway still looks great. See you in several more years!

  • I couldn’t believe how big of a difference a freshly seal coated driveway makes with the look of my house. I realize that there are many other benefits, but the look alone was well worth it. The crew was very professional, showed up at the time that I was told, and cleaned up the area when they left. Thanks Lang’s Seal Coating!
