"Good people to work with. Love the whole-home approach for the same price as just solar panels from other companies. Solar panels, tankless hot water heater, nest thermostats, and radiant barrier work well. A few issues during installation, but they worked everything out to my satisfaction. I would recommend them to others."

"We recently moved into our home and pursued a couple quotes for electrical work. We landed with Surge and I am so glad we did! I could not be more pleased. Serge is incredibly knowledgable, kind and was great with communication. He showed up on time and did wonderful work. He also noticed an AC issue and pointed it out and saved me from having to deal with a future disaster that would have caused a leak. His pricing was extremely good and his work was excellent. I would highly recommend him for any electrical work that is needed!! Thank you Serge!"

"Recently moved to SC and needed a RV power outlet installed. I had previously called and received an estimate(s) from another electrician. I had some knowledge of what was needed for the job, so I felt the first estimates for the other company was a bit too high (quotes ranged from $2800-5800). Then I called Pete. He came out, examined what needed to be done and gave an honest estimate. He was professional, polite and most of all HONEST. I hired him to do the work. In a few days (due to holiday) he came back and completed the job. There were some issues that created more work than what was originally thought, but Pete made sure everything was hooked up correctly and working before he left. He never charged for the extra work and only charge his original estimate (which was under what the other company wanted to charge). I would recommend this company and Pete Justice for any electrical needs in the area. He is honest and trustworthy and does a great job! Thank you Just Electric!"

"There are no words! These guys are top notch humans. We needed a whole new service installed after Helene, there were here first thing Tuesday, and went far above their job. I went to work but my daughter and newborn grandson were here. These guys brought her lunch and ran an extension cord and brought in a commercial fan. They didn't stop there, them and my landlord fixed our generator, we couldn't get it going, left the fan for us to use, filled the gas in the generator. I hope they know just how much we appreciate all their kindness. The city came right out an approved their work, we are all set for when Duke shows up."

FAQs for electrical for home addition or remodel installation projects in Duncan, SC

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
