 Hallmark Building Supplies, Inc.

​​Headquartered in Waukesha, WI and founded in 1974, Hallmark Building Supplies, Inc. is an integrated system of marketing, sales and distribution of branded building materials to the residential and commercial markets. 

You can count on us to supply a wide range of quality building products, in the quantities you need. We assure on-time delivery by managing our inventory, sourcing from other distributors and coordinating shipments directly from the factory.

But that's not all. You can also rely on us to help solve building materials challenges. Through us, you will have ready access to important information regarding the installation, use, maintenance and warranty of our products. And we will keep you up-to-date on the latest industry and product trends.

As a distributor, Hallmark Building Supplies, Inc. provides the market coverage and program execution our suppliers expect. But Hallmark Building Supplies is not a typical distributor. We also support our retailers with cooperative advertising, joint marketing activities, educational programs and more. We are structured as two business units to help serve our channel partner and downstream customers.
