San Diego Granite is the area’s most knowledgeable stone provider. In 2003, two partners combined their 60 years of industry experience to start a company that could handle both residential and commercial jobs, source material from the world’s most reliable partners, and provide customers a seamless experience from start to finish.


They toured the country for the most innovative and sustainable equipment to produce the highest quality work in the shortest amount of time. Their 20,000 sq ft warehouse includes state-of-the-art production equipment, an on-site fabrication shop, and laser-cutting machines to efficiently handle projects of any size.

Now in business for over 19 years, San Diego Granite has proudly completed thousands of large commercial and residential projects, as well as smaller custom home jobs. As a Cosentino and Lowe’s fabricator for 11 years, San Diego Granite was named Lowe's National Fabricator of the Year in 2016 and Lowe's National Builder Fabricator of the Year in 2018. They were rated Best of North County's Kitchen & Bath five years in a row. San Diego Granite is also a preferred vendor with Arizona Tile, Dal-Tile, and Cosentino on imported slab material.
