Tofft Electrical Services
No reviews available
Consider Diamond Electric if...
- ✓ You're completing a straightforward commercial electrical project where Diamond's documented track record with office environments provides confidence in their capability
- ✓ You've verified your homeowner's insurance policy explicitly covers contractor injuries and you're comfortable accepting that liability exposure
- ✓ Customer references matter to you and Diamond's existing positive feedback for wiring repairs aligns with your project scope
- ✓ You're prioritizing a contractor with specific documented experience in the type of work you need completed
Consider Tofft Electrical Services if...
- ✓ Workers compensation insurance is important to you and you want to avoid potential liability if someone is injured on your property
- ✓ You value the additional three years of licensed experience for diagnosing hidden problems in older electrical systems
- ✓ You prefer working with a contractor who maintains comprehensive business protections and insurance coverage
- ✓ You're willing to request references directly since customer feedback isn't publicly documented
Questions to Ask Before Hiring
- → Ask Diamond Electric about their liability coverage specifics and confirm whether your homeowner's policy covers contractor injuries on your property
- → Ask Tofft Electrical Services for at least three references from projects completed in the past year, particularly ones similar to yours
- → Ask both contractors how long their current electricians have worked with them and what continuing education they maintain for code updates
The Bottom Line
Tofft Electrical Services is the safer choice for most homeowners because workers compensation insurance eliminates a significant liability risk that Diamond Electric creates. The additional three years of licensed experience also provides more depth for handling unexpected complications. However, if you've confirmed your homeowner's insurance covers contractor injuries and you're hiring for commercial electrical work where Diamond's documented customer satisfaction directly matches your needs, they're a viable option. Don't proceed with Diamond without explicitly understanding your liability exposure. Request references from Tofft before signing, given their limited public feedback. For typical homeowners prioritizing risk protection, Tofft's insurance coverage is worth the tradeoff of doing more reference checking yourself.

Frequently Asked Questions
If an electrician is injured while working at your home, you could potentially be held liable for medical costs and lost wages. Before hiring Diamond Electric, contact your homeowner's insurance agent to verify whether your policy covers contractor injuries and what your deductible would be. Some homeowners are comfortable with this risk for smaller projects, but it's a real financial exposure you should understand clearly.
Three additional years means approximately 50-75 more projects handled, including complications like outdated wiring, permit rejections, and hidden code violations. For straightforward installations, six years is generally sufficient. For older homes with potential wiring surprises or complex commercial work, those extra years of problem-solving experience can be valuable when unexpected issues arise mid-project.
Limited public reviews don't necessarily indicate quality problems, but they do mean you'll need to do more due diligence yourself. Request a list of recent clients you can contact directly, and ask specific questions about communication, timeliness, and how they handled any unexpected issues. A contractor who's been licensed for nine years should readily provide multiple references.
Yes, commercial electrical work often involves more complex code requirements than residential projects, so that experience is transferable. Commercial electricians typically handle higher voltage systems and more intricate installations. If Diamond's documented commercial experience includes wiring repairs similar to what you need, that's a relevant qualification for residential work as well.

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.
