Our Services

We connect homeowners with dependable electrical panel upgrade across the United States.

Reliable electrical panel upgrade

We upgrade old panels to modern breakers that handle today's load. Our techs pull the old unit and swap it for a new one safely. They check the wiring for any wear and fix it if needed. The work meets local code and passes inspection. You get a panel that won't trip when you plug in a dryer or AC.

Clear scheduling

We work around your schedule, not the other way around. Call us and pick a day that fits your life. We arrive on time and bring all the tools needed. If something changes, we let you know right away. No endless back-and-forth to get the job started.

Honest pricing

We give you a clear quote before any work begins. No hidden fees, no surprise charges after the fact. Our prices match the market for quality parts and labor. You pay for exactly what’s done, nothing more. Transparency builds trust, and we keep it simple.

Prep that matters

Before the upgrade we turn off power and lock out the circuit for safety. We prep the space by removing debris and protecting surfaces. All connections are tightened and double-checked. A proper prep avoids rework and keeps the job safe. We make sure the area is tidy before we leave.

Follow-through

After the panel is installed we test every circuit for proper operation. We walk you through how the new breaker works and answer questions. We clean up any leftover material and leave the garage door closed. If anything issues arise, we’re just a call away at (888) 296-6644 to fix it promptly.

Frequently Asked Questions

We can usually get on the job within a week of your call. Our crew will check the permit requirements for the area and schedule a start date that works for you. We’ll do a quick walk-through to confirm the load needs and any code quirks. If the job is straightforward, we often start the same week you sign the work order. A prompt start helps avoid any loose-circuit hazards.

An upgrade means swapping out the old breaker box for a new, higher-capacity panel. We’ll replace the main breaker, install new individual breakers, and bring all existing circuits onto the new board. The work includes checking grounding, bonding, and ensuring the service entrance conduit is up to code. We also label each circuit clearly for future reference. The whole package meets local safety standards.

Pricing is based on the size of the new panel and the amount of wiring work needed. A 200-amp panel typically runs $2,500 to $3,500, while larger panels cost more. Extra fees apply for any code-required rewiring, conduit upgrades, or if the service drop needs work. We give a written estimate before any work starts, so there are no surprises. Most homeowners find the cost worth the added capacity and safety.

You don’t have to stay the entire time, but we do need you there at the start. Someone must be present to sign off on the permit and give us access to the main service disconnect. After that, our crew can work uninterrupted while you’re out. If any unexpected issues arise, we’ll give you a call to decide the next steps. This saves you time and keeps the project moving.

A typical residential upgrade takes one full day, usually 8 to 10 hours. Larger homes with many circuits or older wiring may need a second day to finish clean-up and testing. We’ll shut off power, swap the panel, reconnect all circuits, and run a final inspection. After the inspector signs off, we restore power and test everything. Most customers are back to normal use by the next morning.

We stand behind our work with a written warranty on parts and labor. If a breaker trips unexpectedly within the warranty period, we’ll come back and fix it at no extra charge. All work follows the NEC and local codes, and we keep records of the installation. Our electricians are licensed, insured, and trained on the latest safety practices. Call us at (888) 296-6644 if you have any concerns after the job is done.

Clear the work area around the existing panel. Remove any stored items, boxes, or flammable materials. Turn off the main breaker and label the circuits. Make a list of any recent electrical issues you’ve had. Have a copy of your home’s electrical permits if available.

We cover the surrounding suburbs and nearby cities in the county. Our service radius includes areas within 30 miles of our base. We can travel to locations that are easy to reach by road. If you’re unsure, give us a quick call with your address. We’ll confirm if we can schedule you.

We tidy up the worksite before leaving. All debris, broken panels, and wiring scraps are gathered and removed. We sweep the floor and wipe down any surfaces we touched. Your home will look as it did before we started. We aim to leave no trace of our presence.

Yes, we can schedule weekend work if you request it ahead of time. Weekend slots are limited, so book early to lock in a date. Our crews work the same hours as on weekdays. We’ll bring all the same tools and parts to the site. Expect the same quality service on Saturday or Sunday.
