Customer Reviews
Comet Plumbing And Sewer
Comet plumbing did a excellent job at my home . A fair price, competent, knowledgeable, efficient , clean and professional! Thank you Andy, I will be calling you for future issues if needed.
We had a drain issue right around the holidays and Andrew fixed it that same day. He and his team have always done great work at a fair price!
Andrew from Comet Plumbing was wonderful! He helped install two clean-outs and fixed a root infested pipe for a reasonable price (plus nice discount). I'll definitely be using them again!
Trenchfree

Consider Comet Plumbing And Sewer if...
- ✓ You need a versatile plumber for various household issues beyond just sewer lines—water heaters, faucets, toilets, garbage disposals, or general pipe repairs
- ✓ Rapid response matters because you're dealing with an active leak, backup, or other urgent situation requiring same-day or weekend service
- ✓ You value direct owner involvement throughout your project, with Andrew handling much of the work personally rather than delegating to crew members
- ✓ Your project might uncover unexpected complications requiring broad plumbing expertise to diagnose and resolve on the spot
Consider Trenchfree if...
- ✓ Your project specifically involves sewer or water line replacement and you want to minimize excavation damage to established landscaping, driveways, or hardscaping
- ✓ You're comparing multiple quotes and want a specialist who understands trenchless technology options that generalist plumbers may not offer
- ✓ You're dealing with Morgan Hill or San Jose municipal sewer inspection requirements for property sales and need expertise navigating those specific processes
- ✓ Your priority is underground infrastructure work rather than general plumbing repairs, and you prefer a contractor whose entire operation focuses on that specialty
Questions to Ask Before Hiring
- → For Comet: If my project is sewer line replacement, do you offer trenchless methods or primarily traditional excavation, and what determines which approach you recommend?
- → For Trenchfree: If inspection reveals additional plumbing issues beyond the sewer line (like corroded supply lines or fixture problems), do you handle those repairs or would I need to hire a separate contractor?
- → For both: Can you provide references from projects in my specific neighborhood that involved similar soil conditions and municipal requirements?
The Bottom Line
Choose based on your project scope. If you need sewer or water line replacement and want to preserve your landscaping with trenchless technology, Trenchfree's specialized focus makes them the logical choice. If you need a versatile plumber for various household issues, emergency response capability, or aren't certain what you'll encounter once diagnosis begins, Comet's 15 years of broad plumbing expertise serves you better. Both are well-qualified contractors with solid credentials—the decision hinges on whether you need a specialist or a generalist.

Frequently Asked Questions
Comet handles sewer line replacements and performs camera inspections, but their reviews don't specifically mention trenchless methods as a specialty. If minimizing excavation is critical for your landscaping, ask Comet directly about trenchless capabilities, or recognize that Trenchfree's entire business model centers on this approach.
Trenchfree's focus is underground line work—sewer and water mains. Their reviews don't mention water heaters, fixture installations, or general repairs. If you need comprehensive plumbing services beyond underground infrastructure, Comet's broader service range would eliminate the need for multiple contractors.
Comet's reviews specifically emphasize same-day response, weekend availability, and arriving within hours of contact. Trenchfree's reviews focus on fast estimate delivery rather than emergency response times. For urgent situations like active backups or leaks, Comet's documented rapid response gives them a clear advantage.
Both companies receive positive mentions for fair and competitive pricing. Trenchfree's reviews specifically note customers comparing multiple quotes and finding their pricing favorable, while Comet's customers mention reasonable rates. For underground line work specifically, getting quotes from both makes sense since Trenchfree's specialization might offer efficiency advantages.

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.
