Locally Owned. Community Focused. Client Committed.

Cornerstone Sealcoat and Markings LLC is proudly owned and operated by Todd and Amanda McCormick, residents of the Chattanooga area who are deeply committed to serving their community with integrity and excellence.


As local business owners, Todd and Amanda understand the importance of protecting your investment — whether it’s a church parking lot, hospital facility, commercial property, or the driveway at your home.

Built on Relationships

Cornerstone isn’t just about sealcoating and striping. It’s about trust.


Todd and Amanda believe that every project — large or small — deserves attention to detail, honest communication, and dependable service. They value every customer and work hard to build long-term relationships with property owners, facility managers, churches, and homeowners throughout the Chattanooga region.



When you work with Cornerstone, you’re not hiring a fly-by-night contractor. You’re partnering with neighbors who care about your property and your experience.
