"I have been wanting to hang flat screen televisions in my son's room and in my master bedroom for years. I finally decided to pull the trigger, but first, I needed new power outlets installed where the television would be mounted. Sergio was the first pro to reach out to me. Sergio scheduled an in home quote with me right away and arrived at the time he said he'd be here. He was very friendly and explained the entire scope of work to me and my wife. We scheduled an install date for two days later. On the day of installation, Sergio again showed up on time. Sergio originally told me that the project would take him approximately 2-3 hours to complete. He completed the project in 1 hour. The quality of his work was absolutely perfect. He even went above and beyond and marked exactly where the studs were behind the wall for me. I highly recommend Sercerval Electric LLC. A+++++ company!!!!!"

"I’ve hired Mynor Electric several times—for new 240V/110V lines, a subpanel upgrade, and full kitchen/bath remodel wiring—and every time, Mynor and his team have been exceptional. He’s punctual, hardworking, and takes real pride in doing things right, not just fast. What sets him apart: • Extremely thorough and code-compliant • Patient, polite, and easy to work with • Troubleshoots thoughtfully and follows up after jobs • Fair pricing, no upselling • Great team (Alex and Nestor are equally reliable) When an inspector flagged a few AFCI/GFCI issues, Mynor personally called to clarify and ensure everything met code. That kind of diligence is rare. I trust him completely and wouldn’t call anyone else for electrical work. Outstanding value and workmanship!"

FAQs for electrical wiring or panel upgrade projects in Livermore, CA

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
