Please see our Special Offers and Promotions, for a limited time only! We service the San Gabriel valley. Owner Jeff Seale has been in the electrical field since 1989. When he was starting out, he witnessed other electricians who were not focused on customer service. They either didn’t complete the work correctly or they charged customers for work that was unnecessary. Jeff believed that customers deserved electrical service that was both dependable and professional. Accurate, born out of the need for committed excellence and communication. We pride ourselves on an outstanding record of quality service. Our experience is testament to the level of service and quality you'll get when you choose Accurate for your electrical needs. We have a staff of highly talented and motivated individuals that are eager to help you with all of your electrical needs. We are excited you have expressed an interest in our services! We look forward to working with you.

"I needed to upgrade the electrical panel in my home and I didn't know who to trust. I did lots of research and found Accurate, and I am glad I did! They made the process super easy and put my mind at ease. In fact, I even had them install a Whole Home Fan at the same time. They sent me text messages when the tech was on his way with his photo and bio, so I knew who was coming to my home. Kenny was the lead with Q and Gabe helping. They were very patient and informative, answering my hundreds of questions. They kept me in the loop with all their findings and did a great job on both installs. Even the process of applying for financing was super easy! I am so happy with Accurate and plan on using them for all my home issues in the future!"

"We recently had our electrical panel replaced and couldn’t be happier with the experience. From the very first call, Mike was incredibly informative and responsive. He took the time to walk us through the entire process—from permitting and scheduling to what to expect on installation day. Every question we had (and we had a lot!) was answered clearly and patiently. On the day of the job, Mike’s team arrived right on time. They were professional, efficient, and courteous throughout. They took great care to keep the work area clean and were respectful of our home. The replacement was completed on schedule, and the quality of the work was top-notch. Everything was labeled clearly, and Mike even followed up afterward to make sure everything was running smoothly. We really appreciated the transparency with pricing—no surprises, just honest and fair. It’s clear that Mike and his crew take pride in their work and genuinely care about their customers. "

FAQs for electrical wiring or panel upgrade projects in Norco, 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.
