"Paul was a pleasure to speak with from the beginning. He gave a spot on estimate for how long the job could take and a flat hourly rate plus parts. His tech, Jaime , came and flawlessly installed the 240V outlet needed for EV charger. I will reach out to Paul and his team for any future electrical needs."

In addition, they removed two old security systems and installed a new outdoor electrical outlet. They responding to my request for a bid quickly and completed the work within less than a week of my request. I would definitely hire them again."

"Ramon and his sidekick are knowledgeable, reliable and quick. Ramon inspected our electrical panel, and explained to us--- the process and what to expect to avoid surprises (which we greatly appreciated). Just like new home owners we were nervous of the experience, but Ramon assured us that he will be in-charge of everything and will walk us step-by-step. They did a good job and we will hire them again for our next future project."

"Mark was very professional, knowledgeable, and friendly. He enlarged my electrical panel and installed a plug for my hybrid vehicle. Also, he took the time to explain the procedures to get the panel approval from the electric company and markings placed by the gas company before his work began. Work was expertly completely in a timely manner. Highly recommend him!"

"Had a circuit breaker trip and did the usual to try and get it to reset (GFCI buttons on electrical outlets, test button in the panel box). Reached out to Go Green and per their request, sent a picture of my panel box. They called me, instructed me to try one more test and wa-la, it worked . . lights and electrical outlets are working! If that wasn't great enough, there was no charge for the phone service. They are now in my address book for the next time I need electrical work or for anyone who reaches out asking for a referral."

"Tim is an excellent electrician. He is skilled and takes pride in his work. Very, very clean. Great communication. He likes to make his work look good and fit in with your needs. He’s one of my favorite pros and has done many jobs for me since I found him on Home Advisor. This time he installed an outlet for my new tankless water heater on my back porch. Even the plumbers admired what a great job he did!"

"Professional. Communicative. On time. Eddie showed up to do the job in upon completion. He pointed out a couple of areas that could potentially be a problem down the line that the last Electrician did and he fixed and replaced the parts from those at no additional charge. He exceeded my expectations as far as how clean and well done the job was. Would definitely recommend to anyone looking for someone you can trust."

FAQs for electrical for home addition or remodel installation projects in Simi Valley, CA

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.
