Consider Delta Electric if...
- ✓ Your project involves an older home with outdated electrical systems where decades of diagnostic experience matters, such as knob-and-tube wiring replacement or troubleshooting mysterious electrical issues.
- ✓ You're planning complex commercial electrical work where regulatory knowledge accumulated over four decades provides added confidence.
- ✓ You're willing to hire based on licensing history alone without customer feedback to guide expectations about communication or working style.
- ✓ You've confirmed with your homeowner's insurance that you're protected if a contractor's worker is injured on your property.
Consider M Multiwire Electric if...
- ✓ You value documented customer feedback showing professional installations and personal customer care, giving you clearer expectations about the working relationship.
- ✓ Your project is residential panel replacement, subpanel installation, smoke alarm systems, or lighting fixtures—work M Multiwire has documented experience completing.
- ✓ Direct owner involvement throughout your project is important to you, ensuring consistent oversight and accountability.
- ✓ You can be flexible with scheduling and willing to discuss appointment reliability upfront, and you've verified your homeowner's insurance covers contractor injuries.
Questions to Ask Before Hiring
- → Ask both companies directly about liability coverage and confirm with your homeowner's insurance whether you're protected if a worker is injured on your property given the lack of workers comp.
- → Ask Delta Electric for references from recent projects similar to yours, since customer feedback isn't publicly available.
- → Ask M Multiwire about their scheduling practices and typical project timelines, addressing the consistency concern raised in feedback.
- → Ask both contractors how they handle complications discovered mid-project and request examples of how they've managed unexpected issues.
The Bottom Line
If your project involves an older home with potentially complicated electrical issues, Delta Electric's 43 years of experience offers a meaningful diagnostic advantage—but only if you're comfortable hiring without customer feedback and can secure strong references. For straightforward residential work like panel replacements or lighting upgrades, M Multiwire Electric provides the transparency of documented customer satisfaction and confirmed owner involvement, though you should discuss scheduling expectations upfront. The workers comp gap affects both equally: before hiring either contractor, call your homeowner's insurance to confirm you're protected if a worker is injured on your property. If that liability concerns you, keep looking for a contractor with workers comp coverage.

Frequently Asked Questions
The experience advantage is real—43 years means exposure to far more electrical scenarios, older building methods, and code changes than 9 years provides. However, without customer feedback, you're hiring blind regarding communication style, reliability, and customer service approach. Ask Delta for multiple recent references and actually call them before deciding.
It's a significant liability concern. If a worker is injured on your property and the contractor has no workers comp, they may sue your homeowner's insurance or you directly. Before hiring either company, call your insurance agent to confirm your coverage in this scenario. Some homeowners decide the risk is manageable; others consider it a dealbreaker.
One mention of scheduling inconsistency isn't necessarily disqualifying, especially when other feedback praises their work quality and customer care. It could reflect growing demand rather than poor management. Ask M Multiwire directly about their current scheduling practices and typical project timelines to gauge whether this remains an issue.
Delta's 43 years of licensing provides substantially more exposure to older electrical systems, outdated wiring methods, and the complications that arise in vintage homes. This experience advantage is meaningful when diagnosing hidden issues or planning upgrades that interact with decades-old infrastructure. However, get references from similar projects before committing.

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.
