Jobsite Supply Co in Grantville stocks commercial construction materials from a warehouse at 4720 Mission Gorge Pl A, San Diego 92120, off Mission Gorge Road in the light-industrial corridor that feeds into Mission Trails Regional Park. Founded in 1987, the company has supplied concrete forming hardware, rebar, wire mesh, fasteners, anchors, structural hardware, and seismic bracing to general contractors across the greater San Diego market for more than three decades — the same material pipeline that kitchen-and-bath remodelers at Coast Design & Build in College Area draw from on active tear-outs. The inventory extends to power tools, diamond blades, saw blades, drill bits, abrasives, safety equipment, ladders, scaffolding, and job-site storage boxes. Jobsite maintains what it describes as the largest strut and hanger stock in Southern California, a specialty line of Unistrut-style channel, beam clamps, pipe hangers, and threaded rod used in commercial HVAC, electrical, and plumbing rough-in. A fleet of delivery trucks runs scheduled drops across San Diego County and into the Los Angeles, Orange County, Riverside, and Inland Empire markets. The 92120 warehouse also carries tilt-up construction accessories, concrete curing compounds, trench drains, and fall-protection harnesses, and the company offers on-site fall protection training and certification for contractor crews. Seismic design and engineering services extend the catalog beyond material supply into California building-code compliance consulting, a layer of technical support that general contractors running residential remodels through Fidelity Home Improvements in College Area tap for anchor-bolt and holdown specification.
