In 1989, Mastic joined the Alcoa family. The two brands, under the umbrella of Alcoa Home Exteriors, delivered the best of both worlds – Mastic’s premium vinyl siding products and Alcoa’s “best in industry” aluminum siding products. Together, an unparalleled offering of premier home exterior products, service and support was created. We are proud that today, one of every four homes with vinyl siding uses Alcoa or Mastic® siding.
