Customer Reviews
Paragon Mechanical
Paragon Mechanical is one of the most reliable and professional teams I've worked with. Todd C. has always been incredibly responsive, knowledgeable, and a true team player. From coordination to execu...
Best group of professionals that you can find in this industry.

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!
Consider Paragon Mechanical if...
- ✓ You need mechanical work beyond standard plumbing, such as HVAC integration or commercial-grade system coordination where broader mechanical expertise matters
- ✓ Your project involves a commercial property or mixed-use building where Paragon's experience with commercial clients becomes relevant
- ✓ You prefer working with an established company that has weathered four decades of market changes and building code evolutions
- ✓ Your timeline is flexible and doesn't require emergency same-day response capabilities
Consider Comet Plumbing And Sewer if...
- ✓ You need residential plumbing work completed quickly, potentially the same day, including weekends and holidays when emergencies strike
- ✓ You value direct communication with the business owner who will personally handle your project and explain issues in detail
- ✓ Your project involves specialized residential plumbing like sewer line replacement, full re-pipes, or water main repairs where Comet's documented project experience directly applies
- ✓ You want a contractor whose entire business model centers on homeowner satisfaction rather than splitting focus between commercial and residential markets
Questions to Ask Before Hiring
- → Ask Paragon Mechanical what percentage of their work involves residential plumbing specifically versus commercial mechanical projects, and whether they can provide references from recent residential plumbing jobs similar to yours
- → Ask Comet Plumbing about their typical response time for non-emergency projects and how scheduling works during their busy periods
- → Confirm with both contractors who will actually be on-site performing the work and what their specific plumbing experience includes
- → Ask both companies about warranty terms on labor and parts for your specific project type
The Bottom Line
For residential plumbing projects, Comet Plumbing And Sewer represents the stronger choice for most homeowners. While Paragon Mechanical's 40-year history is impressive, their broad mechanical contracting focus across commercial and residential markets doesn't match Comet's specialized residential plumbing expertise. Comet's documented rapid response, owner involvement, clear communication, and specific experience with projects like sewer replacements and re-pipes directly address typical homeowner needs. Choose Paragon only if your project specifically requires broader mechanical systems coordination or you're working on a commercial property. For standard residential plumbing work, Comet's specialized focus and proven service model deliver more relevant value.

Frequently Asked Questions
Not necessarily for residential plumbing projects. Paragon's longevity reflects broad mechanical contracting experience across commercial and residential markets, while Comet's 15 years focuses specifically on residential plumbing with documented expertise in projects like sewer line replacement, re-pipes, and water main repairs. For typical homeowner needs, specialized plumbing focus often matters more than general mechanical contracting history.
While Paragon can likely handle plumbing emergencies given their mechanical contracting license, customer feedback doesn't highlight the same-day or weekend emergency response that defines Comet's service model. If rapid response during off-hours is important for your situation, ask Paragon directly about their emergency availability and compare their answer to Comet's documented pattern of arriving within hours of contact.
Yes, the service models differ significantly. Andrew's high personal involvement means direct communication with the decision-maker and consistent execution from diagnosis to completion. Paragon's larger operation may involve different team members and coordination layers, which works well for complex projects but may feel less personal for straightforward residential plumbing. Your preference depends on whether you value owner accessibility or a larger organizational structure.
The $25,000 bond provides identical financial protection from both contractors if work isn't completed as agreed. However, the bond is just one protection factor. Both also carry workers compensation insurance, eliminating your liability risk for on-site injuries. The more relevant safety consideration is their track record and specialization in your specific project type, where Comet's focused residential plumbing experience and documented customer satisfaction patterns provide additional confidence for homeowner projects.

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.
