Questions to Ask Before Hiring
- → For Cunningham Electric: Request contact information for at least five recent customers whose projects match yours in scope, and ask why no online reviews exist despite 30 years in business
- → For Cunningham Electric: Ask how long the current crew has worked together and request documentation of their specific experience with your project type

The Bottom Line
For most residential electrical projects this week, Henry Mechanical offers the safer choice with verifiable customer feedback documenting professional service, on-time performance, and quality installations despite nine fewer years of licensure. Their veteran-tier 21 years qualifies them for complex electrical work, and customer reviews confirm execution quality. Cunningham Electric's 30-year tenure carries weight, but without any customer reviews, you're hiring blind regarding current service standards, crew professionalism, and communication practices. If you need multi-trade work, Henry Mechanical handles it directly. Choose Cunningham only if you receive strong personal referrals with verifiable recent projects matching yours and can inspect their work firsthand before committing.

Frequently Asked Questions
Not based on available evidence. Customer feedback specifically mentions electrical panel installations and electrical work completed professionally alongside other trades. Their 21 years licensed and documented diagnostic accuracy suggest competent electrical capability, though Cunningham's 30-year exclusive electrical focus may offer deeper specialization for unusually complex electrical challenges.
This could indicate reliance on commercial work, word-of-mouth referrals, or simply not requesting online reviews from residential customers. The concern for homeowners is the inability to verify current service quality, communication practices, or how they handle complications. Request detailed references directly and ask why no public feedback exists.
Not automatically. While Cunningham's 30 years suggests deep electrical expertise, Henry Mechanical's 21 years also qualifies as veteran-tier experience with documented customer satisfaction on electrical projects. The nine-year license difference matters less than verifiable service quality, especially when one company has extensive performance documentation and the other has none.
Customer feedback mentions electrical panel installations, which require significant electrical knowledge and permitting expertise. Their documented ability to diagnose issues other contractors missed suggests problem-solving capability beyond basic repairs. For highly specialized electrical challenges like whole-property rewiring or commercial-grade systems, ask specifically about their experience with that scope.

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.
