Common Maryland Panel Issues
We frequently find:
- 100-amp service in homes with central air and electric appliances
- Outdated panel brands flagged by inspectors
- Full panels with double-tapped breakers
- No capacity for EV chargers or heat pumps
- Aluminum branch wiring connections that need proper treatment
What the Load Calculation Tells Us
Before recommending a size, we calculate what your home actually draws and what it's likely to draw as your plans take shape. The result isn't always “go bigger” — sometimes a well-chosen 200-amp panel on existing service is the right call, and sometimes load management covers a specific appliance without a service upgrade.
What the calculation prevents is guessing. A panel sized by guesswork is either too small to matter or bigger than you paid for.
County Permits and Utility Coordination
We handle county permitting and coordinate with the local utility for service upgrades, then install, label, and inspect the new panel.
Montgomery and Prince George's counties each run their own permitting and inspection processes, and the utility has its own scheduling for service work. We manage all three tracks in parallel, which is usually what keeps the total project time reasonable.

Scheduling Around Maryland Utility Work
The utility’s role is the schedule variable in most Maryland service upgrades: the meter and service-side work happens on the utility’s timeline, not ours. We submit the requests early, track the appointments, and build the project plan around them so you’re not left waiting with a half-finished installation.
Most projects run smoothly once the sequencing is right — permit first, utility appointment next, installation day coordinated to both. Where the utility requires an in-person site visit before approving the service change, we schedule that during the estimate phase so it doesn’t surprise the timeline later.
A panel upgrade is also the natural moment to fix smaller annoyances you’ve lived with: the garage outlet that doesn’t work, the bathroom without GFCI protection, the switch that flickers. Bundling those corrections into the same project costs far less than separate visits later, because the walls, permits, and crew are already in place. Tell us about the little things when you book the estimate — Small items like these are also the ones tenants notice first, so fixing them together keeps everyone happy.
Frequently Asked Questions
Do you upgrade panels in Prince George's County?
Yes. We serve both Montgomery and Prince George's Counties.
Do I need 200 amps?
A load calculation determines the right size for your home and plans.
How long does it take?
Installation usually takes one day after permitting and utility scheduling.
Is aluminum branch wiring a reason to upgrade the panel?
Aluminum wiring is corrected at the branch connections using approved methods. Whether the panel also needs replacing depends on its condition — the inspection covers both.
Will a new panel fix my flickering lights?
If the cause is an overloaded or failing panel, yes. If it's a loose connection on a specific circuit, the fix is smaller. Testing identifies which.
