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!"

FAQs for electrical for home addition or remodel installation projects in Ontario, CA

There are several telltale signs that your home is due for an electrical upgrade. You may need to rewire your house if your lights are constantly flickering or your circuit breaker keeps tripping. If you feel mild electric shocks when you touch light switches, hear buzzing sounds, or notice burning smells, you may need to rewire your house, too. Discolored or burnt-looking switches and faceplates are another crucial warning sign. 

Properly installed copper wiring in a residential property can last as long as 50 to 100 years in some cases, but many homes over 30 years old are due for an upgrade. That’s the timeline that many experts recommend, even if it is only a partial update to accommodate technological advancements, increased power demands, and changing safety requirements. 

At $3 to $5 per square foot, the cost to wire a 2,000-square-foot house ranges from $6,000 to $10,000, on average. This can depend on many factors, like the age and complexity of the house and how easy it is for contractors to access the areas they need to get the job done. Opening and repairing walls can further add to your total cost.
