We’re KC Company, your Washington DC area Pella Windows and Doors provider

Back in 1931, James A. Cassidy began doing business as a manufacturer’s agent, with a few lines of “hard materials” including brick, mortar, lime, etc. Following Dad’s footsteps Alan joined the company after honorably finishing his military service in World War II while also completing his education at Catholic University. Alan then became the company president in 1959 then sole owner in 1962. Soon thereafter, Alan acquired the local distributorship for Pella® Windows and Doors.

Under Alan’s leadership, the company grew and built Pella Windows and Doors’ status for outstanding quality in the marketplace. The territory expanded to include the state of Maryland, Northern Virginia, Delaware and Washington, D.C.
