General Information: Founded in 1980, Thompson Creek manufactures and installs vinyl windows, doors, gutter systems and siding, serving the mid-Atlantic region. Last year saw continued growth, as well as change. Just a few years after moving into an 80,000-square-foot facility in Landover, Md., increasing customer demand required that relocation of corporate offices to provide more production space. In 2011, the manufacturer moved all corporate and professional offices to a new facility in Lanham, Md., where it also added a new showroom. The company also remodeled its existing manufacturing operations to increase capacity. Thompson Creek ranked number eight on the 2011 Replacement 100 list of the largest replacement contractors with estimated 2011 revenues of $62 million. The magazine also recognized the company with the Replacement Contractor Service Excellence Award.
