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!
Rosendin Electric
I read good things about them and I admire Rosendin Electric's dedication towards charity and giving back to the community.
Good
Fantastic people!
Consider Rainbow Electric if...
- ✓ You're dealing with an urgent electrical issue like a power outage or circuit failure and need documented evidence of quick emergency response
- ✓ You want a contractor with specific residential diagnostic experience, particularly for complex problems affecting multiple rooms or circuits
- ✓ You value being able to review feedback from other homeowners who've faced similar electrical emergencies
- ✓ You prefer working with a company sized for residential service rather than navigating a larger organization's processes
Consider Rosendin Electric if...
- ✓ Your project involves complex or unusual electrical work where 72 years of institutional knowledge could prove valuable
- ✓ You have references or personal connections who can vouch for Rosendin's residential service quality despite limited public reviews
- ✓ You're comfortable conducting thorough due diligence independently, including requesting detailed residential references directly from the company
- ✓ You value the stability and resources that come with a seven-decade business history
Questions to Ask Before Hiring
- → Ask both companies to provide proof of liability insurance coverage and confirm with your homeowner's insurance whether you're protected if an uninsured worker is injured on your property
- → Ask Rosendin specifically for at least three recent residential customer references with contact information, given the absence of public residential reviews
- → Ask about crew composition and whether the same technicians who handle commercial work will be assigned to your home project
- → Ask Rainbow about their formal safety protocols when working without workers compensation coverage
The Bottom Line
For most homeowners needing residential electrical service, Rainbow Electric offers the more transparent choice with documented quick response times and proven diagnostic capabilities for the power outages, circuit failures, and outlet problems that typically affect homes. Rosendin's 72-year history suggests deep expertise, but without residential customer feedback, you're making a decision based on tenure rather than verified home service performance. The workers compensation gap at both companies requires you to contact your homeowner's insurance before hiring either contractor. If you choose Rainbow, you're selecting documented residential experience. If you choose Rosendin, insist on detailed recent residential references and confirmation of how they handle smaller home projects.

Frequently Asked Questions
Rosendin may focus primarily on commercial or industrial contracts where customer feedback isn't typically published publicly. Long-tenured companies sometimes built their reputation through industry relationships rather than residential consumer reviews. Before hiring them for home electrical work, request specific residential references and ask how much of their current business involves homeowners versus commercial clients.
Eleven years represents solid established experience for residential electrical work. Customer feedback specifically mentions successful diagnosis of multi-room outlet problems and effective power outage troubleshooting, which require good diagnostic skills. Most residential electrical issues fall within this experience range, though extremely unusual situations might benefit from deeper institutional knowledge.
If a worker is injured on your property and the contractor lacks workers comp, you could potentially be sued directly for medical costs and damages. Your homeowner's insurance may or may not cover this depending on your policy specifics. Contact your insurance agent before signing with either contractor to understand your exposure and consider requiring proof of liability insurance at minimum.
Not necessarily. For routine residential repairs like outlet replacements or breaker issues, Rainbow's 11 years provides ample experience, and their documented residential responsiveness may be more relevant than Rosendin's longevity. However, for unusual electrical challenges in older homes or complex rewiring projects, Rosendin's seven decades might offer advantages if you can verify their residential service quality through direct references.

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.
