Start with the right assessment

A full panel, recurring breaker trips or flickering lights deserve a closer look, but they do not automatically mean you need a larger electrical service. The next step may be troubleshooting, a dedicated circuit, panel work or a service upgrade. Tell us what is happening and what you plan to add so we can review the existing setup and explain the options.

Panel replacement or service upgrade?

A panel replacement updates the equipment that distributes power to your circuits. A service upgrade increases the capacity supplied to the property and may also involve the meter equipment, service wiring, main disconnect and grounding. We can review your current equipment and planned electrical needs to help determine the appropriate scope.

What affects the estimate?

Questions homeowners ask

Do I need more capacity for an EV charger or heat pump?

The answer depends on the equipment requirements and your home's existing electrical load. An assessment helps establish whether the existing service can support the addition.

Will the power need to be shut off?

Panel and service work can require a planned power interruption. Ask about the expected outage, permits, utility coordination and scheduling arrangements when discussing the scope.

Can I plan for a future renovation?

Yes—include future appliances, equipment and renovation plans in the conversation so the proposed work accounts for those needs.
