"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."

"Billy at Mattiace Electric did an excellent job changing out an old ceiling fan in my patio for a new one, and changing out electric fixtures in my kitchen and bathroom. He was on time and the job was finished in less than 2 hours. I highly recommend Mattiace Electric and will use them again if I have another electric project that needs to get done."

"I had Excellence Electric install a Tesla charger in my garage. The job was difficult and required a replacement upgraded 200 amp circuit breaker with a 60 amp power line pulled through the attic across the house and dropped down into the garage where the Tesla charger port needed to be installed. Raymond at Excellence Electric completed the job on schedule, took care of all of the HOA and city permits, and kept me updated all the way through the process. I can highly recommend Raymond at Excellence Electric with out hesitation for any electrical work needed on your home or office. Kyle Webb Casa Del Sole residence"

"I hired Alex to install some pendant lights in my kitchen and I couldn’t be happier with the work. He installed our pendant lights beautifully and did it professional, punctual, and friendly. Additionally everything was left clean and tidy after it was done which my wife really appreciated, much different than some others who we’ve had do work for us. I wouldn’t hesitate to recommend them to anyone looking for a reliable, skilled, and professional electrician."

"From the beginning, the experience with Raymond was fantastic. He asked me for pictures of the current electrical panel, and with some additional information, he was able to provide an all-inclusive quote. He handled the permits and coordinated between the city and the power company. He was always very responsive and proactive. His team communicated clearly and was focused on getting every detail done right. I would hire Raymond in a heartbeat for any/all electrical work."

FAQs for electrical for home addition or remodel installation projects in Rancho Santa Margarita, 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.
