"We had our house inspected and found an old mouse nest in one of the electrical panels. The buyers wanted it looked at to make sure no wires were cut or bad. The service guy came was able to come out 2 days after we called. He looked over the box, made a few wires cuts, and plugged the access holes in the bottom of the box so that no more rodents could enter. He also checked out our bathroom light to make sure it was code (we have crazy buyers) without any charge. All in all, he was quick and inexpensive.

"Very communicative! Not only did they call me back, they got in touch to let me know about anything that impacted my appointment. I also really liked how everything they do is on a menu with set prices. It was also great to have the work done the same day as the quote, since the work I needed done could be completed in an afternoon. The electrician also presented estimates for options and work that may need to be done in the future. WireOne will be my first thought next time I need electrical work."

"I called because my outdoor outlet stopped working. When the technician came, his obvious first move was to check whether the safety switch (a little button next to the outlet) had been triggered. It had, and there was nothing to be done besides reset it. When I messaged the person who was in charge that day that I wished I had known, he said there were other things it could have been. But on Christmas Eve, in the spirit, he might have suggested an old lady try first just pushing the button herself. He gave me a discount when I said I wished I had known."

"Unstoppable Electric LLC just installed our Tesla Wall Connector, and wow—what an incredible experience. They were super responsive from the first message, easy to schedule, and showed up right on time. Max is very knowledgeable, professional, and genuinely nice to talk to. He took his time to do everything perfectly—clean, precise, top-quality work with no rush whatsoever. Explained everything clearly, made smart suggestions, and left the garage looking flawless. Pricing was fair and transparent—no surprises. Definitely now my go-to electrician in the area! 10/10 recommend! Thanks again for the stellar work! ⚡️🚗"

"Hired Precision Power twice to help with various electrical needs… rewired my kitchen and then again to help with the finish trim outs. We will continue to hire him. Currently just waiting for our new chandelier to arrive so we can have him back out again! Thanks for the quality work and dependability!"

"This is a truly great company. They provide great customer service and spend time explaining the details and answering questions. My husband obsessed about every single detail and could not deny that it was a no brainer. Our first electric bill since installing the panels was a CREDIT! I was not expecting that. If you have ever considered solar, seriously, just do it. Long term, you can not go wrong."

Electrical questions, answered by experts

Common warning signs of an overloaded electrical panel or meter box include frequent circuit breaker tripping, flickering or dimming lights, scorch or burn marks, and a burning scent coming from the panel. A circuit breaker trips as a protective measure to prevent overheating and potential fires. If you observe any of these signs, turn off the affected circuit breaker and move some devices to a different circuit. If the problem persists after turning the breaker back on, you should contact a professional electrician to resolve the issue.

A standard three-prong electrical outlet typically lasts for about 15 years with normal use and should be replaced accordingly. GFCI outlets may have a longer lifespan of 15 to 25 years. While some outlets can last longer if used infrequently, they can also fail prematurely. Reasons for early failure include poor wiring, an overloaded circuit, improper grounding or installation, or loose plugs. Signs that an outlet is failing include flickering lights, overheating, a discolored or melted faceplate, plugs that fall out easily, or frequently tripping circuit breakers. It is essential to address faulty outlets promptly to avoid safety hazards, especially in homes older than 15 years.

Provided you leave the switch in the off position, your broken bulb shouldn’t be drawing any power. However, there’s always the risk that the switch is turned on by accident, potentially causing electrical damage or even a fire. Plus, broken glass in the home is never ideal. For safety, it’s a good idea to remove broken bulbs as soon as possible. If you’re in doubt, a local lighting professional can help you remove the bulb safely and quickly.

Black is the standard color for hot wires, which transfer electricity to your outlets and switches. Red wires are also hot wires. White (and sometimes gray) wires are considered neutral, delivering power back to the panel. Finally, green wires, which are sometimes bare copper, are ground wires, used to ground an electrical circuit and prevent electrocution.

Yes, a dead outlet can be dangerous and may cause a fire. The lack of power can be due to a hazardous electrical issue that poses a fire risk. If you notice a burning smell, discoloration, or sparks from a non-working outlet, it is a serious issue. It is vital to have a professional electrician investigate and fix the problem as soon as possible.
