"Apollo responded quickly to a quote request. I described the job, provided some photos, and they were able to quote without a visit to the house, which was much appreciated. We scheduled the work for the next week. The communication during this period was very fast and smooth. The electricians arrived on time, we're very polite and professional, we reviewed the job once more, they completed the work, confirming with me the final location of new receptical before cutting started, and before I knew it the work was done. They cleaned up, we did final review of completed job, explanation of what to do in case there are questions or issues, invoice, out the door. Quite painless from end to end and I couldn't be more satisfied. Will hire again, absolutely."

"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"The main complaint I have with Wooding Electric is that the repair was done at a rental property and when I spoke to the gal in the office I told her I wanted an estimate before the work was done. I never got a call to let me know how much the repair would be, and never got a call that the work was done. I had to call my tenant to see if the electrician had been there. I didn't find out how much the repair was going to be until I got the bill in the mail."

Electrical questions, answered by experts

If half of a string of Christmas lights is out, it is likely because of a single burned-out, loose, or broken bulb within that section. Long strands of lights often contain more than one circuit, so when one bulb fails, it can cause the entire circuit (or half the strand) to go dark. To fix this, inspect the unlit section and test each bulb to ensure it is tight and functioning properly. Replacing the faulty bulb or repairing a damaged shunt will typically solve the problem.

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches often result from loose wiring, exposed connections, or other electrical problems that can cause overheating or sparking. Warning signs include crackling, popping, or hissing sounds when you flip the switch, which indicates live electricity that could ignite nearby flammable materials. If you suspect your light switch is faulty, immediately turn off the power at the circuit breaker and contact a qualified electrician to remedy the issue.

Grounding an electrical outlet can take as little as 30 minutes if you only need to replace the outlet or around two hours if you need to add a ground wire. However, more extensive electrical work will take longer, such as hiring an electrician to ground multiple outlets during the same service.

Your outlet should be a ground-fault circuit interrupter (GFCI). These outlets will cut power off in the case of an electrical fire, keeping your home and family safe. Extension cords can also be GFCIs. A local electrician can replace older outlets with GFCIs, if necessary.

If wiring in a relatively modern home is damaged due to sudden events like a fire, a tree falling into the house, or a flood, then homeowners insurance is very likely to cover the cost of replacing the wire.

However, if it’s determined that wiring failed or started the fire because of age, neglect, or not meeting current electrical standards, then insurance won’t be covering any replacement. Also, insurance policies may charge more for particularly old kinds of wiring like aluminum wiring or deny applications altogether.
