Interstate Window & Door Co. has a long, rich history. In 1938, Joseph Pupa Sr. founded Interstate Home Improvement Company in Wilkes-Barre, Pennsylvania, and began providing quality building materials to Northeast Pennsylvania.

We are the first company in the United States to introduce an all vinyl single hung window to the new construction market. In 1985, an affiliated company named Interstate Window & Door Company was fully incorporated.
