Fantastic people!
Consider Courtesy Electric if...
- ✓ You need an electrician with proven residential diagnostic skills, particularly valuable if you have an older home, Eichler property, or electrical issues that haven't been solved by previous contractors
- ✓ Responsive communication and extended service hours matter for your schedule, especially if you need evening or weekend availability
- ✓ You want documented evidence of successful EV charger installations or other modern residential electrical upgrades
- ✓ Customer feedback patterns showing on-time completion and reliable follow-through align with your project management expectations
Consider Rosendin Electric if...
- ✓ You have a large-scale electrical project that may benefit from institutional resources and deep industry connections developed over seven decades
- ✓ Your project involves commercial elements or industrial-grade electrical work where Rosendin's broader experience base may apply
- ✓ You're willing to conduct thorough due diligence through direct references since customer review history isn't available to preview service quality
- ✓ The company's long-standing San Jose presence and familiarity with local codes over multiple generations matters more to you than recent customer feedback
Questions to Ask Before Hiring
- → Ask both companies directly about their 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 Electric for at least three recent residential customer references with contact information, specifically for projects similar in scope to yours
- → Ask both contractors what percentage of their current work is residential versus commercial, and how many residential projects they've completed in the past six months
- → Ask about crew consistency: will the same electricians who quote your project actually perform the work, and how long have they worked together
The Bottom Line
For most residential electrical projects, Courtesy Electric is the clearer choice this week. Their 18 years provides veteran-level expertise while customer feedback confirms responsive communication, strong diagnostic skills, and successful completion of modern residential projects like EV chargers. Rosendin's 72-year history is impressive institutionally, but without customer reviews, you cannot verify their current residential service quality or whether homeowners are a priority focus. The workers compensation gap affects both equally, requiring you to have explicit liability coverage conversations with whichever contractor you choose. Unless you have a large-scale or commercial-hybrid project where Rosendin's deeper institutional resources clearly apply, Courtesy Electric offers more verifiable information about what you'll actually experience as their customer.

Frequently Asked Questions
Not necessarily for a home project. While 72 years demonstrates remarkable institutional stability, it doesn't tell you whether they currently prioritize residential clients or focus primarily on commercial contracts. Courtesy Electric's 18 years is more than sufficient for veteran-level expertise, and their documented residential customer feedback provides concrete evidence of current service quality that Rosendin's tenure alone cannot match. For residential work, proven recent performance often matters more than historical longevity.
Some contractors operate as sole proprietors or use only subcontractors who carry their own insurance, making workers comp optional under California law in certain business structures. However, this shifts potential liability to you as the homeowner if someone gets hurt on your property. Before hiring either company, you must explicitly discuss their liability coverage, verify how they handle worker injuries, and confirm your homeowner's policy provides adequate protection. This isn't a minor paperwork issue—it's a real financial risk.
Yes, it's a legitimate concern when choosing a contractor this week. Customer reviews provide insight into communication style, reliability, and how they handle residential projects. Without this feedback, you're making a decision based solely on their institutional history without knowing if they're responsive to homeowners, manage small projects well, or prioritize residential work. Ask Rosendin directly for multiple recent residential references and actually call them before deciding.
Courtesy Electric has documented successful EV charger installations with customer feedback confirming the work. You can verify they've handled this specific project type recently and completed it satisfactorily. Rosendin may have the capability, but without customer reviews mentioning residential EV charger work, you'd need to request specific references for similar installations they've completed. For a straightforward residential upgrade, documented recent experience provides more confidence.

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.
