On June 12, 1914, William McClure and George Johnston merged each of their companies and incorporated into a new entity.  The new company combined The McClure Company and the GA Johnston Company to form the McClure-Johnston Company.   The new venture opened its doors in the City of Pittsburgh at 1135 Liberty Avenue.  In 1924, the business moved to Smallman Street (underneath what is now 279 North), where it expanded into wholesale roofing and sheet metal.  In 1967, the Company purchased the old Summerfield Machinery buildings on Corey Avenue in Braddock.

Since then, the Company has experienced tremendous growth, expanding their product selection, opening new branches and building a talented team of employees.

In 1977 the Company opened its first branch operation in Johnstown. Since then, McClure-Johnston has expanded continuously. Offering quality and service in the following areas:
