Our Story

In 2001, Karoly Szekeres was driven by a desire to redefine industry standards. Starting as an installer for a well-known big box store, he quickly distinguished himself with his work ethic and keen eye for quality. However, as the years passed, he grew more dissatisfied with the store’s practices – corner-cutting, subpar quality, and a glaring disregard for customer satisfaction. He knew what was missing and was determined to set a new standard.

He began with just one truck and a vision of exceptional service and quality installs. From pulling permits to making calls between jobs, Karoly built his business on integrity, quality, and a promise to customer satisfaction while providing his Gold Standard Lifetime Guarantee on labor. He believes people deserve the best service at the best price.

His hard work was getting noticed in the Tampa Bay area and customers started referring to the way he did things as “The Karoly Difference” – a promise of unmatched quality, meticulous attention to detail, and a customer-first approach. This philosophy became the cornerstone of his success and the hallmark of Karoly Windows & Doors.

Today, Karoly Windows & Doors stands as a leading window and door installation company in Florida. With over 20 employees, we continue to grow, driven by our commitment to excellence and enduring principles of “The Karoly Difference.” We don’t just install windows and doors; we fulfill promises, enhance homes, and build lasting relationships with our customers.
