Welcome to Specified Systems, Inc.

Based in Canonsburg PA, the company covers metropolitan Pittsburgh, western PA to Erie and what is commonly known as the “Tri-State” which encompasses southeastern Ohio, West Virginia, and western Maryland. We have become known for our expertise in window replacement for commercial buildings, window replacement on National Park Service designated properties, and window applications for school construction.

Specified Systems is an erecting distributor. We are not commissioned sales agents, brokers, or wholesalers.

We do our own field engineering and sizing, generate our own shop drawings on CADD, write our own engineered orders on window projects, fabricate storefront– curtain wall– entrance doors in our Washington PA shop, manage our own installations, and service our own work.
