Who We Are

Thank-you for visiting HyattBuildingSupply.com!

Located in Damascus, MD, Hyatt Building Supply has been serving the four county area (Montgomery, Frederick, Carroll, and Howard) since 1947. 

With our exhaustive lumber yard and hardware store, we diligently strive to provide the products our customers and community need. 

We are dedicated to providing exceptional customer service to our customers.

Our lumber yard maintains everything including framing and treated lumber, drywall, plywood, insulation, moulding and trim, masonary block, bulk sand and stone, composite and PVC lumber products including Trex and Timbertech, Therma-Tru and Simonton Doors and Windows, and much more!  Our sales department can also special order numerous items that we do not keep in stock. Delivery service is available.

Inside the store you will find comprehensive plumbing, electrical, paint, hardware and tool departments that offer everything  you need to upgrade, repair, or start that home improvement project you've been planning.  We also offer complete lawn and garden, bird seed, housewares, and automotive departments to provide whatever products you may be looking for.

Hyatt Building Supply partners with suppliers like True Value, Trex, Timbertech, Simonton, Primesource, Delmarva Millwork, Snavley Forest Products, BridgeWaterWholesale, Orgill, Therma Tru, Hillman, and National Manufacturing to just name a few.
