Family-Owned, Triangle Trusted

United Granite NC is a family-owned natural and engineered stone fabricator and installer based in Durham, NC. We serve homeowners and contractors throughout the Raleigh-Durham Triangle — including Wake, Durham, and Orange counties — specializing in kitchen countertops, bathroom vanities, bar tops, fireplaces, and custom stone surfaces for residential and commercial projects.

Our team has cultivated long-term relationships with leading international manufacturers of stone fabrication equipment, quarriers, and slab producers. Those partnerships give us direct access to premium stone at competitive prices and keep our fabrication knowledge at the leading edge of the industry.

We maintain one of the Triangle's largest on-site inventories — over 2,000 colors and more than 120 slabs in stock at our Durham location — so you can see and select your exact slab before fabrication begins. Our in-house fabrication team uses CNC equipment and laser templating to deliver precise, fast results without outsourcing to subcontractors.

Our natural stone offerings include granite, marble, quartzite, travertine, limestone, onyx, and soapstone. Our engineered stone line features authorized premium brands: Cambria, Silestone, and Caesarstone.
