Established in 1907 and owned by the Olson family since 1945, La Mesa Lumber & Hardware on University Avenue is one of San Diego County's last independent full-service lumberyards, operating on four acres in La Mesa. The yard stocks dimensional lumber, plywood, hardwoods, treated lumber, engineered wood products, fencing, and decking alongside a hardware department carrying power tools, fasteners, and building materials — a supply scope that feeds directly into the color-matching workflow at Sherwin-Williams Paint Store in La Mesa for finishing work. Custom milling services cut lumber to non-standard dimensions on site, and same-day delivery runs to jobsites and homes across La Mesa with an $85 minimum, serving both licensed contractors and homeowner DIY projects. The product line includes Milgard Windows in aluminum, vinyl, and woodclad configurations, positioning La Mesa Lumber as a single-source supplier for framing, fenestration, and trim — the same material categories that drive kitchen and bath remodeling projects at Kitchens Plus in La Mesa. The on-site milling operation processes rough-sawn hardwoods into finished boards at specified thickness, width, and surface profiles, handling species from Douglas fir and western red cedar to tropical hardwoods for custom cabinetry and architectural millwork.
