I was able to get a tech, Antonio, out to my home the same day. He worked ho*** ** getting my issue resolved and he succeeded. He's very professional, timely, and I would highly recommend him and the company to anyone having issues."

"The service was stellar from the start. I contacted C. T. Smith Electrical and everything from explaining what I needed to the actual work being done was managed professionally. I provided pictures as well as the electricians came out to assess. The price was very fair for the jobs requested and even when there were some issues that required additional work, the additional cost was fair. They have no way of knowing what is behind the scenes until the start the work and I completely appreciated their assessment and the options available to complete the job. I am so happy with outcome. I will definitely recommend! Thanks C. T. Smith Electrical."

Electrical FAQs, answered by experts

Different types of light switches include single-pole switches (the standard switch in your home), double-pole switches, toggle switches, three-way switches, four-way switches, dimmer switches, and more. 

A single-pole light switch controls the power to a single device, whereas two-way, three-way, and four-way light switches control lights from different locations, increasing the number of connections in the home.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

Yes, Christmas lights on a timer are just as safe as any other Christmas lights are. Most fires caused by holiday lights are due to damage to the strings of lights themselves or from too many lights being plugged into one circuit.

There are several things to try to repair a broken outlet. Whether it's fixable or not may depend on the problem and the type of outlet itself. Start by testing the circuit with an electrical tester and ensuring the breaker switch to the circuit functions as it should. Loose wires are sometimes the culprit and are repairable by fixing the connections.
