Rooted in Westminster's Rich Community Heritage
Westminster began as a farming town known for its apple orchards and open vistas of the Rocky Mountains. The historic Westminster Castle, built in the 1890s, earned the town the title of the Princeton of the West. Today, modern subdivisions mix with established mid-century homes. We tailor our window styles to preserve this unique architectural mix while upgrading total energy efficiency.
