Here's exactly what we do.

Every service below has a flat labor price, a realistic turnaround and a clear list of what's included.

What we do, and what it costs.

Nine jobs we do every week, each with a flat price, a realistic turnaround and exactly what's included. If your project isn't on the list, call us and we'll price it the same way.

  • Diagnostic service call

    Breakers that keep tripping, outlets that went dead, lights that flicker when the dryer runs. We trace the fault to its source, fix what can be fixed on the spot, and tell you plainly what can wait and what can't.

    Turnaround: Next 2 business daysIncludes: Up to 2 hrs on site
  • Whole-home safety inspection

    A methodical walk-through of your panel, grounding, bonding, smoke detector circuits and every accessible device. Ideal before buying, selling, or insuring an older home.

    Turnaround: 1–2 daysIncludes: 40-point written report
  • GFCI & AFCI protection upgrade

    We bring kitchens, baths, laundry, garages and exterior outlets up to current protection requirements, so a wet hand or a frayed cord trips a device instead of hurting someone.

    Turnaround: 1 dayIncludes: Up to 6 circuits
  • LED lighting retrofit

    Swap tired fixtures and recessed cans for efficient LED, with dimmers that don't buzz. We check every box and connection we open, not just the bulb end.

    Turnaround: 1–2 daysIncludes: Up to 12 fixtures
  • Dedicated circuit install

    A new home run from the panel for a window unit, shop compressor, freezer, or home office rack, sized correctly and labeled in your panel directory.

    Turnaround: 1 dayIncludes: 1 new 20A or 240V circuit
  • Whole-house surge protection

    A panel-mounted surge protective device to take the hit from storms and grid switching, plus point-of-use protection where your most sensitive equipment lives.

    Turnaround: 1 dayIncludes: Panel SPD + 2 outlets
  • Level 2 EV charger installation

    Load calculation, a dedicated 240V circuit, and a clean wall-mounted install for the charger you've bought. We'll tell you up front if your panel can carry it.

    Turnaround: 2–5 daysIncludes: Up to 50 ft run
  • Generator inlet & interlock

    Run a portable generator safely through your panel instead of extension cords through a window. Inlet box, interlock kit, and the permit to make it legitimate.

    Turnaround: 3–7 daysIncludes: Inlet + interlock + permit
  • Subpanel installation

    Add capacity for a detached garage, workshop, or finished basement without replacing your main panel. Feeder, panel, grounding, and labeling included.

    Turnaround: About 1 weekIncludes: Up to 100A subpanel

Prices are flat labor rates for homes and small shops within 25 miles of Bessemer City, including standard devices and wire. Larger equipment (panels, chargers, fixtures you haven't bought yet) is priced in writing before any work starts, and county permit fees are passed through at cost.
