About Glenwood Mason Supply

The Glenwood family of companies is comprised of three separate, distinct entities: Glenwood Mason Supply Company Inc., Superior Block Corporation, and Ferguson Hauling Corporation.  All three companies are privately owned and strategically work together to provide the homeowner, construction professional, and design community with the best products and services — all while maintaining the highest standards in innovation, integrity and dependability.

Glenwood Mason Supply is a retail operation that spans twelve acres between our offices and stockyards.  We supply a full range of masonry materials and regularly stock over two million brick and one million block.  Please refer to our products page for a full list and description of our products.  We are proud to be certified by NYC agencies as a Woman-Owned Business Entity (WBE), and can assist the Contractor in meeting requirements for minority participation.

Superior Block Corporation, headquartered in the former Old Dutch Brewery Building, is New York City’s only manufacturer of concrete, lightweight, and architectural block. Superior is an industry innovator in the production of "green" block.  Our state-of-the-art plant produces a full range of strengths, weights, and sizes - all manufactured to strict industry specifications.

Ferguson Hauling Corporation delivers and transports our masonry materials throughout the tri-state area with a concentration on the five boroughs, Long Island, and Westchester County.  Our certified drivers are skilled at safely and efficiently transporting material on the heavily trafficked and congested streets of New York City.
