"Jorge and his crew did a great job removing an old patio ceiling fan and light fixtures and replacing both and relocating placement of the lights. 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."

"Raymond and his team did an amazing job. They ran a new power line from Edison's pole to a new building on my property and installed a new electrical panel. They also ran the wiring underground to my home and created a sub-panel for power. They also installed numerous outlets for lights, including a 220v for power tools & replaced a fan motor from an existing attic fan. They did a wonderful job. They made some recommendations that I didn't even think of. They pulled permits, met with city inspectors, and worked side-by-side with linemen from Southern California Edison, without any issues. Where I believe this company really shines is in their professionalism. They return calls, they show up on time, are respectful and reasonably priced. I highly recommend them to my family and friends. I will definitely be using them again in the future. A+++"

FAQs for electrical for home addition or remodel installation projects in Norwalk, 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.
