Southwest Alarm Service is a licensed California contractor based in Upland, San Bernardino County, holding CSLB license #433111 under classification C7 — Low Voltage Systems, C10 Electrical. At the time this listing was compiled, the license was active with no suspension on record.

The C-10 classification covers service and panel upgrades, branch circuits, lighting, EV charger circuits and code correction work.

Working in the Inland Empire: Expansive clay soils are common across the inland valleys, and they move enough with the seasons to matter for foundations, flatwork and anything tied to them.

Before you hire any electrical contractor: For a panel upgrade, ask what service size is being installed and whether the utility drop and meter are included — those are often quoted separately.

License status can change at any time. Confirm license #433111 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
