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 Castro Plumbing Services if...
- ✓ You're dealing with an exceptionally complex or unusual plumbing issue in an older home where 31 years of institutional knowledge could provide advantage in diagnosing historical system quirks
- ✓ You've received a personal referral from someone who has recently used Castro and can speak to their current service quality and communication style
- ✓ You prioritize maximum licensing tenure above all other factors and are comfortable conducting thorough vetting without extensive review history
Consider Comet Plumbing And Sewer if...
- ✓ You need plumbing service quickly or have weekend/holiday timing constraints, as Comet has documented same-day response capability
- ✓ You value direct owner involvement and accountability throughout your project rather than working primarily with crew members
- ✓ You want predictable communication patterns and detailed explanations, which multiple customers specifically highlight in Comet's feedback
- ✓ Your project could range from simple repair to full system replacement, as Comet demonstrates verified capability across this spectrum
Questions to Ask Before Hiring
- → Ask Castro for three recent customer references from the past six months and contact them to assess current service quality, communication style, and responsiveness
- → Ask Castro about their typical response time for service calls and whether they offer weekend or emergency availability
- → Ask both companies how they handle unexpected complications discovered during diagnostic work and what their change order process looks like
- → Ask Comet about current scheduling availability given their documented demand and fast response reputation
The Bottom Line
Comet Plumbing And Sewer is the clearer choice for most homeowners needing plumbing service this week. While Castro's 31-year licensing history is impressive, Comet's 15 years still represents veteran-level expertise, and their documented strengths in rapid response, owner involvement, clear communication, and fair pricing provide predictable value you can count on. Castro may be equally capable, but their limited review history requires you to invest time in reference checks and vetting. Unless you have a specific referral vouching for Castro's current service quality or your project specifically benefits from maximum institutional longevity, Comet offers less uncertainty and proven performance patterns.

Frequently Asked Questions
Both qualify as veteran-tier contractors with substantial experience navigating code changes and diverse plumbing systems. The 16-year difference could matter for exceptionally unusual or complex historical plumbing issues, but Comet's 15 years still represents deep expertise. The practical difference is that Comet's service approach is documented through customer feedback while Castro's current capabilities require direct vetting.
Licensing and insurance confirm technical qualification and financial protection, but they don't reveal how a company communicates, responds to calls, handles complications, or prices work. Comet's reviews provide concrete insights into these daily operational factors that directly affect your experience. Castro may perform equally well, but you'll need to verify this through direct references rather than established patterns.
For most residential projects, yes. Andrew Rhodes' direct involvement provides consistent quality control, clearer communication, and direct accountability without information passing through multiple people. This matters especially for diagnostic work and handling unexpected issues. However, if you need multiple crews working simultaneously on a large commercial project, a larger operation might be preferable.
Multiple customers report receiving same-day service, including weekends, but this depends on current scheduling. Comet's documented fast response pattern is a meaningful advantage, but you should ask directly about their current availability when you call. Their reputation for rapid response suggests they prioritize quick scheduling when possible.

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.
