Our History

Founded by Stephen D. Donahue in 1989, our company prides itself on delivering exceptional results every single time. At just 19 years old, Stephen D. Donahue started Straight Line Sealing with youthful energy and a strong work ethic. Over the years, the company has earned a stellar reputation in the Buffalo, NY area for delivering quality services. In 1995, we shifted our focus exclusively to commercial seal coating, striping, and asphalt repairs, allowing us to showcase our expertise in the blacktop industry.

The Sealcoating Process

Sealcoating serves as the primary defense against asphalt deterioration by ensuring the surface is free from moisture and debris. Our process involves meticulous surface preparation, followed by a high-quality sealer application, and restripe back to existing layout with a high-quality traffic paint using airless striping equipment. This equipment guarantees crisp, clean edges, minimizing waste and pollution from overspray, while efficiently marking designated areas for optimal functionality and safety.
