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!
Drain Doctor
George was timely, professional, and friendly. Would definitely recommend him!
George was absolutely great! Found the issue and fixed it quickly and without over charging us.
George came out quickly and he cleared our drain. Price was reasonable and he gave us discount for flyer we received by mail.
Consider Comet Plumbing And Sewer if...
- ✓ You value working directly with the business owner throughout your project, ensuring consistent oversight and personal accountability from start to finish
- ✓ Your property is in or near Sunnyvale, making Comet the more locally positioned option for your service area
- ✓ You prefer a smaller operation where the same person diagnosing your problem also completes the repair work
- ✓ You have a straightforward plumbing need and want the personal touch of an owner-operator who maintains direct customer relationships
Consider Drain Doctor if...
- ✓ Your home dates back several decades and may contain older plumbing infrastructure where 34 years of field experience helps diagnose hidden complications
- ✓ You need flexible scheduling or potential for multiple technicians if you have several projects requiring simultaneous attention
- ✓ Your property is in or near San Jose, making Drain Doctor more locally positioned for faster service
- ✓ You prefer a larger team structure with multiple technicians available, which can provide broader coverage during peak demand periods or when your preferred timeframe is urgent
Questions to Ask Before Hiring
- → For Comet: Ask Andrew about his backup plan if he's unavailable during an emergency or already committed to another project
- → For Drain Doctor: Ask which technician will be assigned to your project and request information about their specific experience with your type of plumbing issue
- → For both: Request references from projects similar to yours completed within the past year
- → For both: Ask about warranty terms on both parts and labor for the specific work you need completed
The Bottom Line
Both companies represent solid choices with proper licensing, insurance, and positive customer feedback. Choose Drain Doctor if your home contains older plumbing infrastructure where their 34 years of experience helps navigate complications, or if you need the scheduling flexibility of a team-based operation. Choose Comet if you value direct owner involvement throughout your project and prefer Andrew Rhodes personally handling your work from diagnosis through completion. Your location also matters: Comet serves Sunnyvale more directly while Drain Doctor is positioned for San Jose properties.

Frequently Asked Questions
For straightforward repairs like a dripping faucet or running toilet, Comet's 15 years provides more than sufficient expertise. The experience gap becomes more relevant for complex diagnostics involving older plumbing systems, tracing elusive leaks, or anticipating complications during major projects like sewer line replacements where decades of pattern recognition helps avoid surprises.
With Comet's owner-operator model, you get Andrew Rhodes personally handling your project, ensuring direct accountability and consistent quality. However, availability may be limited if he's committed to other jobs. Drain Doctor's team structure offers broader scheduling flexibility and capacity for larger or multi-phase projects, but you won't necessarily work with the same technician throughout.
Both companies serve Santa Clara County, but proximity matters for response time during emergencies. Comet's Sunnyvale base positions them well for that area, while Drain Doctor's San Jose location favors that region. For scheduled appointments, the location difference is minimal since both travel throughout the county.
If you prefer working directly with the business owner and value personal accountability throughout your project, Comet's high owner involvement is a clear advantage. If your home has older plumbing that may present diagnostic challenges or you need the scheduling flexibility of a larger team, Drain Doctor's 34-year history and multi-technician structure better serves those needs.

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.
