Welcome to KC Company, your Falls Church area Pella Windows and Doors provider

In 1931, James A. Cassidy went into business for himself as a manufacturer’s agent, with several lines of “hard materials” such as brick, mortar, lime, etc. Following Dad’s footsteps Alan joined the thriving business after completing his duty in World War II while also completing his education at Catholic University. Alan then took over as president in 1959 eventually becoming sole owner in 1962. Within a short time after, Alan acquired the local distributorship for Pella® Windows and Doors.

In the years that followed, the company prospered and developed Pella Windows and Doors’ status for amazing quality in the marketplace. The territory expanded to include the state of Maryland, Northern Virginia, Delaware and Washington, D.C.

Kevin Cassidy joined the family business in 1974, marking the third generation of the Cassidy family to work for K.C. Company. Kevin was promoted to the role of president in 1987 and took ownership in 1997. In 2006, Stan Stokes assumed the role of president of the KC Companies. Kevin continues to passionately influence the organization serving as the Chairman of the Board.
