"Hired Ken and his team for a complete knob and tube rewire of our historic 1911 home as well as installation of LED trim kits, a ceiling fan and some light fixtures. The cost v scope and quality of the work was the best value I've seen as a new homeowner. All members of the company, from the on-site techs to Ken were friendly, hard-working, responsive and communicated well. All tasks, estimates and invoicing were clear, concise, and open to questions and discussion. It was a rewarding and satisfying experience which one does not usually expect from contractor projects. I highly recommend including Johnson Electric in your bidding process, you will not be disappointed."

"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."

"I reached out to Electric Zone for a few items we wanted in our home; a couple outlets installed in our closets and assistance in wiring a new pendant light. Haik from Electric Zone called us and arranged to come by the same day we reached out so that he could come by and provide an estimate, the price was fair so we decided to move forward with them. When Haik and his coworker arrived they discussed every step with us before proceeding, we were very happy with the options and works provided. Definitely recommend, we will be reaching out to Electric Zone again if we need more work in the future."

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