One of the company’s standout factors is that its elements are handmade in an underground curing process. “We cure the tiles in an underground cave, previously an abandoned limestone mine of 4.5 million square feet. It started in 1936 until 1963. It was a nuclear bomb shelter for 10 years, and it took the owners 10 years to get the building permits,” Steve Kamin, a partner of Hartstone Tile, explains. “Once they got the building permit, they made it a livable, habitable place. There are sprinkler systems throughout, there is air circulating and there are several businesses down there. But we were the first business there. Then, we expanded to we have about 56,000 square feet.”
Choosing the right tiles is a collaborative process. Kamin works directly with interior designers to help make their client’s visions for their outdoor spaces come to life, noting his frequent work with Georgia-based companies like Anna Booth Interiors in Atlanta and Cristi Holcombe Interiors in Alpharetta. Their partnerships lead to timeless-looking features for modern and luxury pool decks, backyard oases, patios, multilevel backyards and more.
Hartstone Tile’s attention to detail has made it an award-winning company. In 2024, they won the Home Building Industry (HOBI) award for work on a modern farmhouse-style house in Darien, Conn. The project was led by architect Christopher Pagliaro of Christopher Pagliaro Architects, with landscape architecture by Tara Vincenta of Artemis Landscape Architects and construction by builder John Sullivan from EC Structures. In 2023, the company won the Major Achievements in Merchandising Excellence (MAME) award for “Hardscape of the Year” in Charlotte, NC.
One thing Kamin prides himself on is his hands-on customer service, which is one of the benefits of having a small business. “Sometimes we make a mistake. Sometimes the installer makes a mistake,” he says. “I want to make sure it’s fixed. I just feel that we need to do what’s right.”
