Under CSLB C-10 license #615231, Master Electric on Blackton Drive in La Mesa covers residential, commercial, and industrial electrical work across the 91941 ZIP. Whole-home troubleshooting and outlet replacement require the same access-point coordination that Key Maker Locksmith navigates when rekeying locks and upgrading deadbolt hardware during concurrent home-improvement projects. Panel upgrades for 200-amp service bring older La Mesa homes into compliance with current NEC load calculations for modern appliance demands and EV charging circuits. Garage and workshop electrical builds — subpanel installation, dedicated 240-volt tool circuits, and overhead lighting — run parallel with the concrete surface preparation and polyurea floor coating projects at Finishing Touch Concrete Coatings, Inc on garage renovation timelines. The highest-value project scope covers full agricultural electrical distribution including well-pump motor wiring, irrigation controller circuits, and three-phase equipment hookups for rural and semi-rural properties.
