Frequently Asked Questions
No. California requires separate licenses for electrical and plumbing work because they involve completely different skill sets, code requirements, and safety considerations. Serrano Electric is licensed only for electrical work, while Cupertino Plumbing is licensed only for plumbing. Using an unlicensed contractor for either trade puts you at risk and may violate local building codes.
Review volume varies widely among established contractors and doesn't necessarily reflect quality. Some veteran companies built their reputation through decades of referrals before online reviews became common. Cupertino Plumbing has actively cultivated an online presence, while Serrano Electric has limited review history despite 39 years in business. For contractors with sparse reviews, asking for direct references is appropriate.
Yes, $25,000 meets California's minimum bonding requirement for licensed contractors and provides standard consumer protection if work isn't completed as agreed. For very large projects exceeding this amount, you can discuss additional protections like progress payment schedules. Both companies carry workers compensation insurance, which is equally important for protecting you from liability if workers are injured on your property.
While Serrano Electric has five more years of licensed operation than Cupertino Plumbing, both qualify as veteran contractors with over three decades of experience. At this level of tenure, both have navigated multiple economic cycles, building code changes, and technological advances in their respective trades. The experience difference is less relevant than determining which trade you actually need and evaluating each company's specific expertise for your project type.

How We Compare Contractors

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.
