Customer Reviews
Rainbow Electric
Our power went out shortly after new year. Our electrician from Rainbow Electric was very patient and understanding of my family's situation. Who would want to live without power during the winter? O...
Sam came out quickly when we had a fuse we couldn't get to reset. He found the problem, which was effecting outlets all over the house and fixed it right! Excellent, highly recommend!
Simtek Electric
Always great to work with!
Consider Rainbow Electric if...
- ✓ You're dealing with an urgent electrical issue and want documented evidence of quick response times and availability for emergency situations
- ✓ Clear communication matters significantly to you, especially if you're stressed about electrical problems, and you value recent customer feedback confirming patient, understandable explanations
- ✓ Your project involves diagnostic work across multiple circuits or rooms where Rainbow's documented troubleshooting skills are relevant
- ✓ You're located in or near Milpitas and want a contractor centered in your immediate area
Consider Simtek Electric if...
- ✓ Your home is older and may have outdated wiring, electrical panels, or systems requiring someone who has worked through multiple generations of electrical standards and materials
- ✓ Your electrical problem is unusual or intermittent, where 37 years of exposure to uncommon scenarios provides diagnostic advantage
- ✓ You prefer established, long-term local presence over recent online feedback and are comfortable verifying current service quality through direct references
- ✓ You're located in or near Gilroy and want a contractor with decades of familiarity with the local area and building requirements
Questions to Ask Before Hiring
- → Ask both contractors about liability coverage specifics and confirm whether your homeowner's insurance covers injuries to uninsured workers on your property
- → Ask Simtek Electric for recent references from projects similar to yours to verify current service quality and communication standards
- → Ask Rainbow Electric about their experience with your specific type of electrical system or problem, particularly if your home is older than their 11-year history
- → Ask both contractors how long their current crew has been working together and who will actually be on-site for your project
The Bottom Line
If you need confidence in responsiveness and communication backed by recent customer experiences, Rainbow Electric provides that validation despite shorter tenure. Their 11 years is sufficient for most residential electrical work, and their documented quick response and diagnostic skills address common homeowner priorities. Choose Simtek Electric if your project genuinely requires deeper experience—older homes with unusual wiring, complex diagnostic challenges, or uncommon electrical configurations—but only after obtaining and checking recent references to confirm their veteran expertise translates to current service quality. Either way, verify liability coverage before work begins since neither carries workers compensation insurance. For standard residential repairs with time-sensitive needs, Rainbow's documented performance makes them the lower-risk choice this week.

Frequently Asked Questions
The experience is valuable, especially for complex or unusual problems, but you cannot assume longevity equals current service quality. Many veteran contractors maintain excellent standards, while others coast on reputation. Ask Simtek for recent references and call them to confirm timely communication, responsiveness, and professionalism that match your expectations before committing.
If a worker is injured on your property and the contractor lacks workers comp, you could potentially be held liable for medical costs and damages. Before hiring either contractor, contact your homeowner's insurance to understand your coverage and consider requiring proof of liability insurance. This is a real financial risk that warrants verification, not just acknowledgment.
Eleven years represents established experience for most residential electrical issues including circuit troubleshooting, panel work, and common repairs. However, if your home has very old wiring systems, uncommon configurations, or you're experiencing truly unusual problems, Simtek's additional 26 years of field exposure provides broader diagnostic context. Match the contractor's experience to your project's actual complexity.
It depends where you're located. If you're in northern Santa Clara County near Milpitas, Rainbow is your local option. If you're in southern areas near Gilroy, Simtek is geographically closer. For emergency service or multiple-visit projects, proximity matters for response time and trip charges, though both serve the broader county area.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
