"Too bad I had to give them even 1 star. Mr. Sparky will find the absolute most expensive test and diagnostics to run for the simplest issue. Jeremy took advantage of a stressed out woman who simply had an arcing outlet and charged over $1100 to replace it and tighten connections in 2 outlets on the same circuit. Jeremy logged over 2 hours on the job per the owner, while spending hardly over an hour. Half of which was spent writing a quote for $8000 worth of work while enjoying and laughing at the tv in the background. Jeremy was lingering inside and outside the house after the work was complete. Upon speaking to the owner, the owner made personal attacks against myself and my wife. The owner proceeded to tell me that I should have been at home taking care of my family rather than being at work. Terrible company with terrible leadership. They will respond and say I was treating them poorly. At the end of the day they have to pay for their cookie cutter business by over charging ALOT."

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.
