Electrical Panel Upgrades in Baltimore & the DMV
100A → 200A and 200A → 400A service upgrades, permitted and inspected.
If your home still runs on a 60A or 100A panel, you are living on borrowed capacity. Add a heat pump, an EV charger, a hot tub, or a finished basement and the panel becomes the bottleneck — breakers trip, lights dim, and insurers start asking questions.
We replace the panel, the meter can when needed, and the grounding system, then pull and close the permit with your jurisdiction. Baltimore City, Baltimore County, Howard, Anne Arundel, Montgomery, DC, Arlington, Fairfax — we handle the paperwork.
What’s included
- Load calculation on your actual usage, not a guess
- New 200A or 400A panel with copper bus and full breaker set
- Meter can, service entrance cable, and mast replacement if needed
- Ground rods and water-bond brought to current code
- Permit pulled and inspection scheduled in your name
- Labeled directory so every circuit is identified
- 3-year warranty on workmanship
Signs you need this
- Federal Pacific, Zinsco, or Challenger panel (known fire hazard)
- Fuses instead of breakers
- Breakers that trip when the microwave and toaster run together
- No room left for a new circuit
- Rust, scorch marks, or a burning smell at the panel
Electrical Panel Upgrade — frequently asked questions
How much does a panel upgrade cost in Baltimore?
Most 100A to 200A upgrades run $1,850–$3,200. Jobs needing a new mast, meter can, or 400A service run $3,200–$4,500. You get a written flat price before we start.
Do I need a permit?
Yes, and we pull it. A panel swap without a permit can void your homeowner's insurance and stall a future sale.
How long will my power be off?
Typically 4–6 hours during the swap. We schedule the utility disconnect and reconnect so you are back on the same day.
Do I need 200A for an EV charger?
Not always. About 80% of homes we check can add a Level 2 charger on the existing panel. We run the load calc during the free estimate.
