Learn More About Our Industry Leading Service

San Diego Rock Supply is a family owned and operated business that has been serving San Diego County with quality landscape materials since 2003. We began as a husband and wife operation with two goals in mind: keeping our overhead costs low while passing the savings onto our customers without compromising product quality, and giving our customers unparalleled service and the ability to deal directly with the owners.


Over the years, we have continued to expand our inventory and workforce; but, we have remained dedicated to our two main goals - PRICE and SERVICE!


If ever you are not satisfied with the service you have received, please contact us and we will do all we can to resolve the problem. Thank you for taking the time to visit our site, and please feel free to contact us with any questions.
