"I ordered a rewire for most of my house, fix GFCI receptacles in my garage, and update EV charging receptacle. Communication - 4/5 The project manager, Onri, was responsive for the most part and answered any questions I had. Timeliness - 5/5 The crew arrived earlier than I’d expect them. Quality - 5/5 The crew laid down blankets to avoid damaging the floors. They made minimal cuts to gain access to route new wiring. The crew was very professional and seemed like experts. Correctness - 3/5 The crew was not aware I ordered an installation for EV charging, fixing drywall, and fixing the garage GFCI connectors. They had to do two follow up visits to fix the GFCI receptacles. Overall, I had to double check their work. They rewired two bedrooms to the same breaker when they should have been split. The important thing is that they corrected everything that was wrong and was very professional about it. I’d hire them again."

"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 for home addition or remodel installation projects in Castro Valley, 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.
