Customer Reviews
Adept Electrical Solutions
Donte was great from first contact to post install hand holding. Will surely call him up for other electrical work.
Called Adept Electric for a consultation with an electrical problem at my residential house in Fremont. He and his assistant evaluated my situation, and they were able to find the problem, and repair ...

Williams Electric
Geoff did a wonderful job upgrading our electrical panel. He was on time, communicated well via text/email, on budget, did great work, and most importantly passed inspection with flying colors. 100% ...
Geoff installed a car charger. He knew exactly what he was doing, arrived when he said he would and was easy to work with. Reasonably priced, charged exactly what he said he would.
Consider Adept Electrical Solutions if...
- ✓ You're installing solar, battery storage, or smart electrical systems where Adept's documented project diversity directly matches your needs
- ✓ You value detailed explanations and patient communication throughout complex projects, particularly if you're unfamiliar with electrical work
- ✓ Your project involves troubleshooting, recessed lighting, or multi-phase installations where their meticulous workmanship reputation matters
- ✓ You need same-day availability for urgent electrical issues based on their responsive service pattern
Consider Williams Electric if...
- ✓ You have a straightforward panel upgrade or EV charger installation where Williams' 39 years of experience provides confidence in handling complications
- ✓ Your home is older and may present hidden issues where decades of field experience diagnosing problems becomes valuable
- ✓ You prefer no-surprises pricing and budget certainty, which aligns with their documented track record of matching quotes to final costs
- ✓ You're in Oakland where their local presence is established over nearly four decades
Questions to Ask Before Hiring
- → Confirm your homeowner's insurance covers contractor injuries on your property, and ask each company about their general liability coverage limits since neither carries workers comp
- → Ask Adept for references on projects similar to yours, especially if involving solar or battery systems, to verify their capability breadth
- → Ask Williams how they handle unexpected complications in older electrical systems given the experience advantage, and request examples from similar vintage homes
- → Request crew composition details from both companies—who specifically will be on site and how long they've worked together
The Bottom Line
For solar systems, battery installations, or projects requiring detailed explanations and meticulous attention, Adept Electrical Solutions' diverse capabilities and communication strength make them the better fit despite less overall experience. For straightforward panel upgrades or EV chargers, especially in older Oakland homes where decades of troubleshooting experience matters, Williams Electric's 39-year track record provides valuable insurance against complications. Critically, verify your homeowner's insurance covers contractor injuries before hiring either company, as both lack workers compensation. If your project is complex or involves newer technology, lean toward Adept; if it's standard work where you value experience depth, choose Williams.

Frequently Asked Questions
It can matter significantly if complications arise. Williams' 39 years means they've likely encountered every variation of outdated wiring, undersized services, and hidden code violations in older homes. However, Adept's 5 years is still experienced-tier, and their broader documented project range suggests strong technical capability. For straightforward installations in newer homes, the gap matters less.
Adept Electrical Solutions clearly demonstrates solar and battery system experience in their documented projects, with customers specifically praising their work on these installations. Williams Electric's available project data focuses on panel upgrades and EV chargers without documented solar work, making Adept the evident choice for solar-related electrical needs.
If a worker is injured on your property, you could be held liable for medical costs and lost wages if your homeowner's insurance doesn't cover it or has exclusions. Before hiring either company, call your insurance agent to confirm contractor injury coverage and consider requiring proof of general liability insurance with adequate limits from whichever contractor you choose.
Adept receives frequent mentions of patient explanations and answering questions thoroughly, suggesting they invest time in customer education during complex projects. Williams gets positive marks for straightforward communication and project updates via text and email, indicating efficient, professional interaction without extensive detail. Choose based on whether you want educational depth or streamlined efficiency.

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.
