Your panel is outdated, damaged, or frequently trips
For repeated trips or damaged equipment, we evaluate the affected circuits and panel condition before recommending replacement. A larger main breaker alone is not a capacity upgrade.

Panel Replacement or a Larger Electrical Service?
A worn or damaged panel and an undersized electrical service are different problems. Replacing equipment may address its condition without increasing the utility service rating. Adding capacity requires evaluating the meter equipment, service conductors, utility connection, and calculated load together.
- 100A, 200A and service-equipment upgrades
- Overhead and underground service configurations
- Load calculations and permit-ready planning
- Clean, code-compliant installation by a C-10 contractor
When to Call
Signs You Need Professional Service
Electrical problems can worsen when ignored. Contact a licensed electrician when you notice any of these conditions.
You need capacity for an EV charger, solar, or a major appliance
For EV charging, solar, or new appliances, we check the calculated load, equipment ratings, and circuit space. Load management may be an option for charging when the existing service is otherwise suitable.
There are signs of overheating, corrosion, or obsolete equipment
For corrosion, overheating, or obsolete equipment, we assess accessible connections, enclosure condition, and replacement options. The proposal should distinguish urgent repairs from planned improvements.
Your remodel or property expansion requires additional circuits
For remodels and additions, we compare the planned circuits and equipment with the existing service and identify the required electrical changes before construction proceeds.

Electrical Panel Upgrades: What to Expect
Evaluate the existing service
We review the service rating, equipment condition, planned loads, working space, grounding and bonding, and overhead or underground configuration. This establishes whether you need replacement, additional circuits, or a service-capacity increase.
Define the permit and utility work
The proposal identifies equipment, circuit changes, permit responsibility, and utility coordination. Meter location, conductor routing, and required clearances can affect the scope before installation begins.
Plan installation and restoration
Service work requires a planned power interruption. We discuss access, outage expectations, inspection, and reconnection arrangements for your project. Confirm whether stucco, drywall, painting, and other finish repairs are included in the written proposal.
What affects the cost?
Panel-upgrade pricing depends on the service rating, meter configuration, overhead versus underground feed, equipment location, conductor routing, grounding work, permits, and finish repairs. A straightforward replacement and a relocated service with underground work are different scopes. Request an itemized proposal that identifies included work and exclusions.
What to send for an estimate
Send your property address, photos of the closed meter and panel, a wider view of the surrounding wall, and a list of planned appliances or charging equipment. Keep covers in place. Tell us about existing solar, batteries, generators, or any power-related symptoms.

Helpful Answers
Panel Upgrades Questions
Clear information helps you plan electrical work safely and confidently. Project requirements vary by property and jurisdiction.
Do I automatically need a 200-amp panel?+
No. The correct service size depends on a load calculation, the condition of the existing equipment, and your planned electrical loads. Gridline evaluates the property before recommending an upgrade.
Can a panel upgrade help support an EV charger?+
Yes. A service or panel upgrade can create capacity and breaker space for EV charging, although load-management equipment may be an alternative when the existing service is otherwise suitable.
Are permits and utility coordination usually required?+
Service-equipment replacements and capacity upgrades generally require permitting, inspection, and coordination with the serving utility. The exact process depends on the jurisdiction and project scope.
How long will my power be off during a panel upgrade?+
The outage depends on the scope, utility disconnect and reconnect arrangements, and inspection requirements. Ask for the expected outage and restoration plan before scheduling. Let Gridline know about medical equipment, refrigeration, remote work, or other power needs.
Does a panel upgrade include stucco or drywall repair?+
Finish repairs depend on the written scope. Confirm whether patching, texture, painting, and any work around a relocated panel are included or need another contractor before accepting the proposal.
