ProVia is nestled within the rolling hills of Sugarcreek, Ohio, the heart of the nation's largest Amish population. The company was started in a garage by Bill Mullet more than 40 years ago and has grown into a nationally known manufacturer of high-quality entry door systems, energy-efficient, vinyl replacement windows, super polymer vinyl siding,  artfully-crafted, manufactured stone, and lifetime-lasting metal roofing. ProVia has built a reputation in the building products industry for quality, old-world craftsmanship and personal care for customers, which extends to every part of our culture. The company has been through many changes to accommodate its growth, including expansions, acquisitions, and the implementation of state-of-the-art production equipment. The current headquarters, constructed in 1984, underwent major renovation and expansions in 1993, 2001 and 2005 and 2012/2013.

Today, ProVia remains privately owned by the Mullet family and continues to invest in its facilities, employees, customers and research & development. The company continues to manufacture outstanding replacement door, window, vinyl siding, manufactured stone and metal roofing products with a dedicated growing team that distributes products throughout most of the United States.
