Unbeatable Quality Since 1947


Calstone has serviced Northern California with high-quality concrete masonry and landscaping products for over 70 years. Established in 1947, in San Carlos, Calstone has three State-of-the-art manufacturing facilities located in Gilroy, San Martin, and Tracy. We also have a distribution facility in Galt. These regional locations enable us to provide our products as far north as Eureka, as far south as Fresno and as far east as Reno. 

Calstone produces over 600 varieties and sizes of concrete masonry, landscaping products, and custom-made unit. We routinely add new equipment and innovative processes in our quest for continuous improvement as evidenced in our first-in-the-world patented 6 color blending process.


Our management participates in industry associations such as the California Concrete Masonry Association (CMACN), National Concrete Masonry Association (NCMA), Interlocking Concrete Pavement Institute (ICPI), and a host of local organizations. Service is Calstone’s hallmark, and our customer relations policies stem from our strong family-run business ethic that spans four generations. Whether you are an architect, engineer, contractor, or end user, we have highly qualified sales and customer service reps ready to provide assistance with your project.
