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!
KDS Plumbing
Fast dependable reasonable priced
They do great afordabe work. Old school!
Consider Comet Plumbing And Sewer if...
- ✓ You need service quickly or on a weekend, as customers consistently report same-day and holiday availability from Comet
- ✓ You value detailed communication and want thorough explanations of problems, with multiple customers praising Andrew's diagnostic explanations
- ✓ You prefer working with an owner-operator who handles fieldwork directly, ensuring consistent quality and accountability
- ✓ You want to review specific feedback about pricing fairness and project completion before committing
Consider KDS Plumbing if...
- ✓ Your project involves older plumbing systems or legacy infrastructure where KDS's 31 years navigating code changes and evolving technologies may prove valuable
- ✓ You have a direct referral from someone who has used KDS and can vouch for their work quality and responsiveness
- ✓ You're willing to thoroughly vet the company yourself through direct conversation, given the absence of public customer feedback
- ✓ Their San Jose location is significantly more convenient for your property access and scheduling
Questions to Ask Before Hiring
- → Ask KDS directly for references from recent projects similar to yours, and follow up with those customers about response times and communication quality
- → Ask KDS about their typical response time for service calls and whether they offer weekend or emergency availability
- → Ask both companies about their current workload and realistic timeline for starting your specific project
- → Ask Comet about their experience with your specific plumbing issue, particularly if it involves older or complex systems
The Bottom Line
If you need service this week and value verified responsiveness, Comet Plumbing is the clearer choice. Customers consistently confirm fast response times, weekend availability, and detailed communication—exactly what you need when making a quick decision. KDS's 31 years demonstrates staying power, but without customer feedback, you're hiring blind on the aspects that matter most for service experience. Choose KDS only if you have a strong direct referral who can vouch for their responsiveness and communication, or if their extra experience is essential for a particularly complex legacy system issue.

Frequently Asked Questions
For standard residential plumbing work, both companies qualify as experienced veterans capable of handling most projects. KDS's additional years matter most if you have very old plumbing systems, historical home complications, or unusual legacy infrastructure. For typical repairs, replacements, or even full re-pipes, Comet's 15 years provides sufficient expertise, with the advantage of verified customer service patterns.
This could reflect different business models, customer bases, or online presence strategies. Some established contractors rely entirely on repeat business and referrals without cultivating online reviews. However, as a new customer without a direct referral, you'll need to work harder to verify KDS's service quality, communication style, and responsiveness before hiring.
Comet Plumbing has documented evidence of rapid response, with customers reporting same-day service and weekend availability. Multiple reviews specifically mention Andrew arriving within hours of contact. KDS may offer similar responsiveness, but you'll need to confirm this directly since no customer feedback addresses their availability or response patterns.
Owner involvement can be an advantage, ensuring accountability and consistent quality control. Comet's Andrew handles fieldwork directly, which customers appreciate. For KDS, ask directly whether you'll work with the owner, a project manager, or field technicians, and how they ensure quality control across their team after 31 years in business.

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.
