"What: NOT Plumbing. Electrical wiring for/and installation of flood lights above garage door, side walkway to backyard, and backyard. Also installed porch light. Pros: On time, courteous Comments: Backyard floodlight was on all day & all night and on the same electrical source of the lights in the laundry room light and side walkway to backyard. The only way to turn it off was to turn off the electrical switch in the box, which turned off all 3 lights mentioned above. The flood lights were supposed to be on, with a timer, only during dark hours, but either it was on all night because they tied it to the laundry & walkway "wire" or electrical switch, OR they didn't put it on timer, or some other reason. They sent another team out to fix the issue within the next few weeks. Recommendation: Buy your own light fixture, inform YOU want to pick and have them install. Otherwise, they go with their own vendor and the alternative did not look anything like the style we wanted."

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.
