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.
- Permit pull and utility coordination
- New 200-amp main breaker panel (Square D, Eaton, or Siemens)

- Properly sized service entrance conductors and grounding
- Neat, labeled circuit directory

- Breakers that trip repeatedly
- A panel that hums, smells warm, or feels hot

- Historic district homes need careful work that respects the structure — we don't tear up walls if we don't have to.

- We work with local GCs on Washington County remodels and additions.
- How long does a panel upgrade take?
- Most residential 200-amp upgrades are a one-day job. Power is off for a few hours while we cut over.
- Do I need a permit?
- Yes — and we pull it. Panel work has to be inspected, and we coordinate with the utility for the disconnect/reconnect.
- Do you really serve all of Jonesborough?
- Yes — we cover Jonesborough and the surrounding Washington County area, including Historic Jonesborough, Boones Creek, Telford, Limestone. Typical response time is 45–75 minutes.
