Electrical Panel Upgrades
More capacity, fewer tripped breakers, and a panel that can actually support the home you have today.
An electrical panel that was correctly sized decades ago often isn't sized for a modern household. Central air, an EV charger, a finished basement, a larger kitchen and a house full of electronics all add load that older 60-amp or 100-amp services were never designed to carry. When a panel is undersized, the symptoms show up as breakers that trip under normal use, warm panel covers, or a flat refusal from an inspector or insurer to sign off on further work until the panel is addressed.
A panel upgrade replaces the main breaker panel — and, where needed, the service entrance and meter equipment — with a unit rated for higher amperage, typically 150A, 200A, or 400A for larger homes. Beyond raw capacity, a new panel also brings the home's main disconnect, grounding and bonding, and breaker types (including AFCI and GFCI protection where code requires it) up to current standards, which is often the bigger safety improvement even when the old panel's amperage was technically adequate.
We evaluate the existing service before recommending anything: what the current panel is rated for, what's actually connected to it today, and what you're planning to add — an EV charger, a generator, a workshop, an addition. That load calculation determines whether 150A is enough or whether 200A or higher makes more sense, so you're not paying for capacity you'll never use or upgrading to a size you'll outgrow in five years.

How it works
From first call to finished work.
Assess
We inspect the existing panel, service entrance, and grounding, and calculate your household's real electrical load.
Plan & permit
We recommend a panel size, pull the required permit, and coordinate any temporary power arrangements with the utility.
Install
The old panel is safely de-energized and replaced; most residential panel upgrades are completed in a single day.
Inspect & restore power
The work is inspected per local code, then power is restored and every circuit is tested before we leave.
Frequently asked
Electrical Panel Upgrades questions, answered.
How do I know if I need a 150A, 200A, or 400A panel?+
It depends on your home's size and what you're running now or planning to add. A smaller home with gas heat and no EV charger may be comfortable at 150A; a larger home with electric heat, an EV charger, and a workshop often needs 200A or more. We size this from an actual load calculation, not a guess.
Will I lose power during the panel upgrade?+
Yes, for part of the day. The utility disconnects power at the meter while the panel is swapped, and we restore it once the new panel passes inspection. We schedule the outage window and let you know what to expect beforehand.
Does a panel upgrade require a permit?+
Yes, in every jurisdiction we work in. We handle the permit application and schedule the required inspection as part of the job — it's not an optional add-on.
