"These guys came out and worked in the dead of cold in the winter in an old barn and got the job done. It was a good value for the price point. They aren't the cheapest but you wouldn't want that with a professional electrician. John has a good crew of people working with him and they'll get the job done. This was a 100 amp to 200 amp upgrade with a sub panel and electric car charger install."

"Simpson Elelectric 207 was fantastic! Derek, the owner, was very professional. They upgraded my service and panel and did it quickly and correctly when i couldn't get anyone else to even call me back. They arrived on time and when they left they cleaned up so well it was like they were never even here. I would and will hire them again!"

Quality installations are key to the success of an electrical system, that's why we stand behind our installations with a 1-year workmanship warranty.

"After contacting a couple of other electrical companies, we chose to go with Simpson Electric and I’m very glad we did. Tyler Simpson and his team were very knowledgeable, professional, well mannered, prompt and understanding in getting the work we needed completed on time! Tyler thoughtfully looked at the project and helped us save money while getting a little more than what we asked for. They cleaned up the areas they worked in and performed some troubleshooting to ensure that everything was working as it should! I trust them wholeheartedly. I would call and/or recommend Simpson Electric anytime."

Electrical wiring or panel upgrades FAQs

Upgrading an electrical panel may not significantly increase your home's value, but it can make your property more appealing to potential buyers. A modern electrical panel enhances safety and meets current electrical demands, offering peace of mind to home buyers. This can make your home easier to sell and potentially lead to higher offers when the time comes.

Upgrading an electrical panel from 100 to 200 amps costs between $750 and $2,000, not including the cost of running new wiring for additional circuits. This upgrade increases your home's electrical capacity, allowing you to safely use more appliances and modern electrical devices without overloading your system. It's a valuable investment for homes with growing electrical needs.

Yes, in most circumstances, you will need a permit to upgrade your panel. Contact your local building department if you’re upgrading the breaker box, moving it, upgrading your amperage service, or adding a new subpanel. If you’re just replacing a light switch, receptacle, or single breaker in the electrical box, you may not need a permit, but it’s always a good idea to check or speak to a professional.

When only the unit is exchanged, replacing an electrical panel takes four to eight hours. When associated wiring and additional components require removal and reinstallation, the process extends to 20 to 30 hours. A professional electrician deploys a dedicated team to remove the old panel, install the new one, and update all wiring with precision, ensuring your system meets current safety codes.

Replacing an electrical panel begins by turning off the power and notifying the utility company. The electrician secures all required parts, disconnects wiring safely, and inspects the system before removing the old panel. Following safe disposal, the new panel is firmly installed, and all wiring is reconnected and updated to current safety codes.

An electrical breaker panel lasts 25 to 40 years when maintained correctly and inspected annually. This proven lifespan guarantees a long-term, safe electrical system. Regular maintenance and prompt professional evaluations preserve the panel’s performance and secure your home’s power supply, ensuring continued safety and system efficiency.
