Thad Ziegler Glass, Ltd. is recognized as the oldest family-operated glass company in the United States, established in 1893 by William Ziegler and his nephew, Carl. Originally named Ziegler & Ziegler, it began by specializing in products such as paint, wallpaper, and plate glass in San Antonio, Texas. Over the years, as the business evolved, Thad Ziegler Glass shifted its focus to auto and window glass, becoming a leading factory outlet for these products by 1940.
Following several ownership changes and strategic pivots, the company has remained in the Ziegler family and is still run by its fifth generation, marking a legacy of commitment to quality and customer satisfaction. The firm transformed from Ziegler & Ziegler to Thad Ziegler Glass Co. and eventually became Thad Ziegler Glass, Inc. in 1969. The focus has expanded to include a variety of glass products for commercial and residential applications, including safety glass, insulated glass, mirrors, shower doors, and more.
With multiple locations serving San Antonio, Boerne, and Kerrville, Thad Ziegler Glass prides itself on its long-standing reputation within the community and is dedicated to providing exceptional customer service. The company boasts a philosophy rooted in ethical business practices, which has garnered them industry awards and referrals from satisfied customers who appreciate the craftsmanship and reliability of their services. Whether it's custom glass solutions for home renovations or commercial glass repair, Thad Ziegler Glass stands as a testament to durability, innovation, and family tradition in the glass industry.
