Welcome to Prime Masonry Materials

Prime Masonry and the Campbell family have been building Southern California for over 50 years. Starting with a small block and paver manufacturing facility in Oxnard in the 70s, our founder saw the need for high-quality and local building materials during a time when Ventura County was transforming from farm land and citrus trees, to the communities we call home today. During the 1980s Shawn Campbell took over operations of the business and expanded production. During the 1990s, Shawn opened 7 retail stores throughout Southern California, and another block manufacturing facility in Bakersfield. Shawn Campbell and his businesses played a huge role in the growth of Southern California, supplying building materials to the towns of Thousand Oaks, Westlake, Newbury Park, Camarillo, Oxnard and Ventura. In 2010 Shawn Campbell and his son Ian teamed up to revive a number of struggling retail building supply stores, and today Prime Masonry Materials proudly operates its two material supply yards in Oxnard and Santa Maria. The Campbell family and Prime Masonry have been with Southern Californian’s through economic recession, booms, fires, and earthquakes. We are proud members of the local community and look forward to continuing to build Southern California for years to come.
