Company Profile
Free Builders Supply has served San Diego County's building trades since 1954, a second-generation, family-owned supply yard in San Marcos and one of the larger building-materials yards in California.
We're an independent supplier, not a contractor, with drywall and lath at the core of a broad line that also includes stucco and plaster, block and concrete, rebar and fabrication, sand, gravel and topsoil, cement, scaffolding, and trade tools.
Contractors, architects, and homeowners across San Diego, Orange, Riverside, and Los Angeles counties rely on us for jobsite delivery and a deep, ready stock from our single Linda Vista Drive yard.

Google Business Contractor Feedback

“We shifted our custom residential framing packages to Free Builders Supply last season. Their takeoff estimators are meticulous—they spotted a load-bearing transfer discrepancy in our drawings that would have cost us thousands in framing corrections. Elite service.”
“Their crane truck operators are the best in the business. Staged three heavy framing drops on a steep, narrow hillside lot with zero damage to the trees or neighbor's fence. Very dependable logistics dispatch.”
“Top-notch independent supplier counter. They don't just scan tags—they actually understand engineered wood and local code requirements. Whenever I call, I get direct answers on dispatch times and pricing buffers.”
