"Antonio, was very friendly, he replaced the outside light and the kitchen light. The kitchen fan had a down pole. I wasn’t satisfied with the movement. He took the fan down numerous times to make sure I was satisfied. He did a great job and I will use his services again."

Electrical questions, answered by experts

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.

If you’re replacing wires from an electrical meter box to the breaker box, you may also consider installing a new meter or replacing or repairing the breaker box . You can tell if the circuit breaker is bad if you’re dealing with tripping or worrisome burning smells. Both projects should also be handled safely by a licensed electrician.

To determine if an electrical outlet is blown, look for visible signs of damage such as a burning or smoky smell, burn marks, or a melted or discolored plastic cover. If you notice a burning smell, contact an electrician immediately. Other signs include a plug that keeps falling out or the outlet not working when you test it with different devices. For further troubleshooting, you can use a voltage tester or multimeter to check for power; a reading of zero indicates a problem. Also, check your circuit breaker or fuse box to see if the circuit was tripped and reset it if necessary. If these steps don't resolve the issue, the outlet may need to be replaced.

Single switch installs are quick DIY projects, but you should consider enlisting the help of a pro for more complicated replacements—like a smart switch or if you live in an older home with outdated wiring. Professional electricians are trained in the latest code regulations. They are also insured, licensed, and bonded.

Incorrectly wiring a single-pole switch results in the connected light or device not turning on or tripping the circuit breaker. Although it doesn't matter which terminal the hot wire and the load wire connect to, mixing up a circuit wire with a ground or having loose connections can prevent the switch from working.
