Johnson, Finch, & McClure Construction, Inc. in Lakeside holds CSLB licenses #392277 and #1028492 covering General Building, Drywall, Insulation and Acoustical, Lathing and Plastering, and Doors, Gates and Activating Devices. Above-ceiling mechanical coordination with Hi-Tech Air Conditioning determines T-bar grid layout and plenum clearances before acoustical-tile installation begins on commercial tenant-improvement projects. In operation since 1977, the firm is an AGC San Diego member and a Western Wall & Ceiling Contractors Association participant specializing in metal-stud framing, gypsum-board finishing, lath-and-plaster systems, and acoustical ceiling assemblies for hospitals, schools, airports, and commercial towers across Southern California. Electrical rough-in within metal-stud partitions framed by JFM runs through pre-punched knockouts coordinated with Tokai Electric Inc, ensuring conduit and low-voltage pathways clear the drywall plane before taping begins. Highest-complexity scopes include demountable partition systems with integrated power and data raceways, multi-layer Type X fire-rated assemblies meeting UL Design Numbers for one- and two-hour separations, and curved-radius soffits formed with flexible gypsum board.
