Electrical Panel Upgrade for Jonesborough Homes & Businesses

If your home still runs on a 100-amp panel, a fuse box, or an old Federal Pacific or Zinsco panel, an upgrade isn't just a convenience — it's a safety upgrade. We replace tired service equipment with modern 200-amp panels that handle today's loads: heat pumps, EV chargers, hot tubs, induction ranges, and shop equipment.

We've been doing electrical panel upgrade work across Jonesborough and Washington County for years. From Historic Jonesborough, Boones Creek, Telford to the surrounding communities, we know the local housing stock, the local code officials, and the utility companies that serve Jonesborough, TN. That means faster permits, cleaner installs, and zero surprises.

  • New 200-amp main breaker panel (Square D, Eaton, or Siemens)
  • Whole-home surge protection option
  • Properly sized service entrance conductors and grounding
