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!
Trademark Plumbing
Great service efficient and reliable
Consider Comet Plumbing And Sewer if...
- ✓ You want same-day or emergency service with documented fast response times, including weekends and holidays
- ✓ You prioritize full insurance protection including workers comp to avoid potential liability if someone gets injured during your project
- ✓ You value direct communication with the owner who handles much of the fieldwork personally
- ✓ You want to review recent customer feedback showing consistent service quality before making your decision
Consider Trademark Plumbing if...
- ✓ Your project involves unusual plumbing challenges where nearly three decades of technical experience could prove valuable
- ✓ You're willing to verify current insurance coverage directly and confirm your homeowner's policy adequately covers contractor injuries
- ✓ You're comfortable proceeding without recent customer reviews to validate current service quality and communication practices
- ✓ The company can provide recent references and demonstrate their crew's stability despite limited public feedback
Questions to Ask Before Hiring
- → For Trademark: Ask to see current workers compensation insurance certificates and confirm what liability protection exists if a worker is injured on your property
- → For Trademark: Request references from projects completed within the last 12 months to verify current service quality and crew performance
- → For both companies: Ask for a detailed written estimate and timeline for your specific project to compare responsiveness and clarity
- → For Trademark: Ask how long their current plumbing crew has been working together given the limited customer feedback available
The Bottom Line
Comet Plumbing And Sewer is the clearer choice for most homeowners this week. The company provides complete insurance protection including workers comp, documented fast response times, and consistent customer feedback showing reliable service and communication. While Trademark's 29 years suggests deeper technical experience, the absence of workers compensation coverage creates real liability concerns, and limited customer reviews make it difficult to verify current service quality. Unless your project involves highly unusual plumbing challenges where Trademark can demonstrate specific expertise and provide proof of current insurance coverage, Comet offers a more transparent, lower-risk option with proven customer satisfaction.

Frequently Asked Questions
For routine repairs and replacements, both companies have sufficient experience. Trademark's extra 14 years becomes more relevant for unusual situations like diagnosing complex sewer issues in older homes or navigating unexpected complications. However, Comet's 15 years still represents veteran-level expertise for most residential plumbing needs.
If a plumber gets injured at your home and the company lacks workers comp insurance, you could potentially be held liable through your homeowner's insurance. This is a real financial risk. You should verify current coverage directly with Trademark and confirm with your insurance agent what protection your homeowner's policy provides.
This could reflect different business models—Trademark may focus on commercial work or serve a smaller residential client base. It might also indicate they don't actively collect reviews. Either way, it means you're making a decision with less insight into their current service quality, communication style, and customer satisfaction levels.
If you're dealing with an urgent situation like a leak or backup, Comet's documented fast response times provide real value and minimize water damage risk. For planned projects without time pressure, Trademark's deeper experience might matter more, but only if they can provide current references and proof of insurance.

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.
