Whether it’s troubleshooting a single circuit or designing a full electrical layout for new construction, we have the expertise and tools to deliver safe, code-compliant results.
Are you licensed and insured to perform electrical work in Tennessee?
Yes. We hold a current Tennessee Electrical Contractor license and maintain full liability and workers’ compensation insurance. All of our electricians meet state requirements for training and continuing education, ensuring our work aligns with both the National Electrical Code (NEC) and local Johnson City ordinances. Copies of our license and insurance certificates are available upon request.

We offer 24/7 emergency service with a typical on-site response time of 60 minutes or less within Johnson City city limits. Our technicians arrive fully stocked with common replacement parts, minimizing downtime and restoring power or resolving safety hazards as quickly as possible.
Do I need a permit for my electrical project, and will you obtain it?
Most major electrical modifications—such as service panel upgrades, new circuits, and whole-home rewiring—require a permit from Johnson City’s Building & Codes Department. As part of our turnkey service, we handle the entire permitting process, including plan submission, fee payment, and coordination of inspections. This ensures your project is fully compliant and avoids costly fines or delays.
How do you ensure the safety and quality of your electrical installations?
Safety and quality are built into every step of our workflow. We start with detailed load calculations and circuit mapping, use UL-listed components, and follow NEC 2023 guidelines. All wiring is megger-tested for insulation resistance; connections are torque-verified with calibrated tools; and final assemblies undergo thermal imaging to detect hotspots. A licensed supervisor signs off on every project, and a written warranty is provided before job closeout.
Can you help lower my energy costs through upgraded electrical systems?
Absolutely. We perform on-site energy audits that analyze lighting, motor loads, HVAC controls, and power-factor efficiency. Based on the findings, we recommend LED lighting retrofits, smart timers, occupancy sensors, high-efficiency transformers, and solar or battery integrations. Many upgrades qualify for TVA rebates and federal tax incentives, which we assist you in applying for to maximize your return on investment.
