Thoma Electric | Qualified Electrical Contractor in San Luis Obispo, CA

Our comprehensive electrical inspection for San Luis Obispo homes and businesses is designed to ensure safety and reliability. Our licensed electricians systematically check your panel for proper amperage and signs of wear, test all outlets and GFCIs for correct function and grounding, inspect wiring for safety hazards, and evaluate the overall system's capacity for your current and future needs. Given the local issue of loose connections causing flickering lights, we pay special attention to terminal tightness and wire integrity. You'll receive a clear, detailed report of our findings and any recommended repairs or upgrades.

GFCI outlet failures are a common issue we address in the San Luis Obispo area. These safety devices are designed to trip when they detect a ground fault, which can be caused by moisture intrusion in bathrooms or kitchens, a faulty appliance plugged into the circuit, or worn-out internal components in older outlets. Loose wiring connections behind the outlet, another frequent local problem, can also cause intermittent tripping. Our service technicians are experts at diagnosing the root cause—whether it's the outlet itself, the wiring, or a downstream issue—and providing a reliable, code-compliant repair to restore safety and function.

Absolutely. Our philosophy is that 'important projects come in all sizes.' As a full-service firm, we have dedicated divisions for major construction, small projects, and service work. This means whether you need an outlet repaired in your home, a full panel upgrade, or are managing a multi-story commercial or healthcare project, you're working with the same locally-owned company with over 60 years of engineering and construction experience. Our team of 60-70 employees allows us to deploy the right expertise, from a seasoned service technician to a project manager who has overseen complex LEED-certified builds, ensuring quality and consistency at any scale.
