Thanks for the wealth of information, I really appreciate it. Thanks again, great service which unfortunately is getting rare.

Tom Morris

Erik is more than a rep for HDG Building Materials; he’s a landscape architect with design sensibility. In addition to buying products, I’m handing him designs for the homes in which we’re using those products. Erik knows the capabilities of his products. He’s been helpful in coming up with designs to meet the architecture of the house. His design and architecture sense make HDG products more effective. This added feature is why I like doing business with HDG Building Materials.

Marty Treece
Principal, Treece and Lambert, LLC.

We worked with HDG Building Materials on one of the most complicated jobs we’ve done in our 40-year history. For the Horton Plaza Improvement project in San Diego we used a variety of shapes and sizes of dimensional stone in various finishes, vertical and horizontal installation methods, and including stairs on a radius. From initially receiving stone samples to visiting a quarry on-site in China, HDG provided great service and inspired confidence.
