Based in Chino, San Bernardino County, Visual Information Systems Company holds California contractor license #442769, classified B (General Building, C10 Electrical, C45 Sign). License status at the time of compiling this listing: active, with no suspension recorded.
A C-10 electrical license covers the wiring, panels, circuits and fixed equipment that distribute electrical power through a building.
Working in the Inland Empire: Inland Empire summers are long and hot, and Santa Ana wind events each autumn put real load on anything attached to the outside of a building.
Before you hire any electrical contractor: If you are adding an EV charger, ask for a load calculation on the existing panel before anyone quotes the circuit.
License status can change at any time. Confirm license #442769 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
