Frequently Asked Questions
Granite Electric has been licensed for 34 years versus ASF Electric's 30 years, a four-year difference. At this experience level, both have seen multiple technology transitions and code updates, so the practical difference is minimal. The customer feedback patterns matter more than this credential gap.
Multiple customers report difficulty reaching ASF Electric, which can create frustration during bidding and project coordination. If you need responsive communication for scheduling or questions during your project, this pattern is a legitimate concern. Ask ASF directly about their communication protocols before hiring.
With 30 years of licensing, ASF Electric certainly has the technical capability for complex electrical work. However, Granite Electric has specific customer feedback documenting successful completion of panel upgrades, whole-house rewiring, and EV installations, providing more concrete evidence of recent complex project experience.
Both serve San Mateo County with ASF based in Daly City and Granite in Brisbane, neighboring communities just a few miles apart. Either contractor can reasonably serve your location in this area, so geography should not be a deciding factor for this comparison.

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.
