How much does an electrical panel upgrade cost in Lewisville, TX?

The cost of a residential panel upgrade in Lewisville depends on panel size, service entrance condition, and whether the meter base needs replacement. A 200-amp panel swap on a home with an intact service entrance is typically on the lower end. Homes that need a service entrance upgrade along with the panel will run on the higher end. We give you a written job-price quote before work starts. Contact Mr. Electric of Frisco to schedule an assessment.

Does an electrical panel replacement require a permit in Lewisville?

Yes. The City of Lewisville requires a permit for any panel replacement or service upgrade, which triggers a city inspection after completion. Unpermitted work creates real problems during home sales: inspectors flag it, title companies ask questions, and some lenders won't close. So we pull the permit and schedule the inspection for you.

What size panel does my Lewisville home need?

Homes from the 1970s and 1980s—especially near Old Town or along Valley Parkway—frequently have 100-amp or 150-amp panels. A 200-amp panel comfortably handles most modern homes. Adding an EV charger draws 40 to 50 amps on a Level 2 circuit, so confirming available headroom matters before installation. Larger homes with significant outbuildings sometimes benefit from a 200-amp main with a subpanel.

What warning signs mean I need a panel replacement?

Breakers that trip on normal loads, a burning or hot-plastic smell near the panel, visible burn marks on breaker faces, flickering lights, and a panel with no available slots are all signals worth taking seriously. Lewisville homes with Federal Pacific or Zinsco panels should have them assessed regardless of visible symptoms—both brands have documented histories of breaker failures. For an electrical panel replacement, an electrical safety inspection is a practical first step.

What other electrical services does Mr. Electric of Frisco offer in Lewisville?

Beyond panel upgrades, we handle circuit breaker replacement , dedicated circuit installation , EV charger installation , whole-house surge protection , and emergency electrical service . We also serve homeowners in Carrollton , Celina , The Colony , and more.

Can I add circuits to my existing panel instead of replacing it?

Sometimes. If your panel has open slots and sufficient service amperage, adding a circuit is simple. But many Lewisville homes that need added circuits also have nearly full, outdated, or undersized panels. Our electrician assesses your panel's available capacity before recommending a path—adding circuits to a maxed-out panel isn't a fix.

What an Electrical Panel Upgrade Involves in Lewisville, TX

Our Frisco electricians provide electrical panel services in Lewisville and follow a consistent sequence to protect you and meet the City of Lewisville's inspection requirements.

The job starts with a load calculation—a measurement of your home's actual electrical demand based on square footage, circuit count, and the specific appliances you run. Older Lewisville homes built in the 1970s and 1980s frequently have 100-amp services sized for a world without whole-home surge protection, high-efficiency heat pumps, or Level 2 EV chargers. A standard modern home typically needs 200-amp service; a home with an EV charger, a hot tub, or a workshop often needs 200 amps with room for a subpanel later.

After the load calculation, we pull the required permit through the City of Lewisville. Unpermitted panel work surfaces during home sales—buyers' inspectors flag it, and lenders push back. We handle the permit and coordinate the city inspection. We de-energize the panel at the meter, document the existing breakers and wiring, and mount, wire, and label the new panel circuit by circuit. We test every circuit before the inspector arrives.

Upfront Pricing

You get a written quote before we touch a single wire. Our electricians assess your home, run the load calculation, and give you a firm job price—not an hourly estimate that balloons when the job runs long. Panel upgrades in Lewisville typically take one full day for a standard 200-amp residential electrical panel replacement. If your service entrance also needs work, we quote it separately and explain it clearly before we start.

Identifying Safety Concerns

Federal Pacific Stab-Lok panels, found in many Lewisville homes built between 1950 and 1990, have breakers that sometimes fail to trip under overload—a documented fire risk. Zinsco panels carry a similar track record. When we find these, we explain the issue and what a full swap costs. We don't push upgrades on panels that don't need them, but we won't stay quiet about a genuine hazard.

Licensed Electricians

Texas requires electricians to hold a state license from the Texas Department of Licensing and Regulation (TDLR) to do panel work. General contractors who aren't licensed electricians can't legally pull an electrical permit in Lewisville. Our electricians carry their TDLR licenses and work to NEC 2020 standards, which Lewisville has adopted.
