Questions to Ask Before Hiring

- → For both: Request references from projects completed in the last year that match your specific scope of work
The Bottom Line
Choose based on your project type first: Mirkovic Electric for electrical work, Trenchfree for plumbing. If you need electrical services, Mirkovic Electric offers veteran-level expertise and competitive pricing, but you must address the workers compensation gap by confirming your liability coverage. If you need sewer or water line work, Trenchfree provides specialized trenchless technology with full insurance protection. Both companies demonstrate professional execution and high owner involvement, but they serve fundamentally different needs and cannot be compared as alternatives for the same project.

Frequently Asked Questions
Identify whether your project is electrical or plumbing first. If you need panel upgrades, circuits, or EV charger installation, you need Mirkovic Electric. If you have sewer line, water line, or underground pipe issues, you need Trenchfree. If you're unsure about your issue, describe the problem to each company and they can clarify which trade handles it.
This is a real liability consideration. If a worker is injured on your property and the contractor lacks workers comp, you could face a lawsuit or claim against your homeowner's insurance. Contact your insurance agent to confirm your policy covers this scenario, and ask Mirkovic Electric what liability protections they carry. Trenchfree's workers comp coverage eliminates this homeowner risk.
It matters within the electrical trade specifically. Mirkovic Electric's 34 years means extensive experience with code changes, unusual residential configurations, and diagnosing hidden electrical issues that newer contractors might miss. Trenchfree's 14 years is still established-level experience for plumbing work, sufficient for handling standard and complex sewer line projects.
You can't compare pricing across different trades meaningfully. Mirkovic Electric's customer feedback specifically mentions significant cost savings compared to other electrical quotes. Trenchfree customers note competitive pricing compared to other plumbing contractors. Get multiple quotes within the same trade to compare effectively.

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.
