KDS Plumbing
Fast dependable reasonable priced
They do great afordabe work. Old school!
Consider Allstar Plumbing if...
- ✓ You want verified evidence of quick response times, with multiple customers reporting technicians arriving within an hour for urgent plumbing issues
- ✓ You value clear communication and transparent pricing, as customers consistently mention receiving explanations and cost estimates before work begins
- ✓ Your project may be complex or challenging, where Allstar's documented problem-solving abilities on difficult repairs provide reassurance
- ✓ You prefer a contractor with demonstrated repeat customer satisfaction spanning multiple years
Consider KDS Plumbing if...
- ✓ You're comfortable hiring based solely on licensing credentials without customer feedback to verify current service quality
- ✓ You have a direct referral from someone who has personally used KDS Plumbing and can describe their actual experience
- ✓ You're willing to be among the first to publicly document this company's service approach and reliability
- ✓ The slight edge in years licensed (31 vs 29) holds particular significance for your decision, though both are veteran-tier contractors
Questions to Ask Before Hiring
- → Ask KDS Plumbing why they don't have customer reviews available and request references from recent projects you can contact directly
- → Ask KDS Plumbing about their typical emergency response time and whether they provide pricing estimates before beginning work
- → Ask both companies about their current crew stability and how long their lead technicians have been with the company
The Bottom Line
Unless you have a personal referral who can describe their direct experience with KDS Plumbing, Allstar Plumbing is the clearer choice. Both companies have identical credentials and veteran-level experience, but Allstar provides transparency about what you're actually hiring: quick emergency response, upfront pricing, and proven problem-solving abilities. KDS may deliver identical service, but you're choosing blind. For a homeowner who needs to make a confident decision this week, go with the contractor whose performance is documented.

Frequently Asked Questions
No, not meaningfully. At 29 and 31 years respectively, both are veteran contractors who've worked through decades of plumbing systems and code changes. The difference between a 3-year and 10-year contractor matters significantly; the difference between 29 and 31 years is negligible for practical purposes.
Some established contractors don't actively solicit online reviews or may rely entirely on word-of-mouth referrals. However, this leaves you without independent verification of their service quality, response times, or communication style. Before hiring, ask them directly for references from recent projects you can contact.
Their reviews show specific patterns: technicians typically arrive within an hour for emergencies, they provide clear pricing before starting work, and they handle complex diagnostic problems well. Multiple customers report using them repeatedly over years, which indicates consistent quality beyond a single good experience.
Not based on licensing length alone when both are this experienced. Instead, choose based on verified service patterns. Allstar's documented quick response times, transparent pricing, and repeat customer satisfaction provide concrete reasons to hire them, while KDS requires you to trust credentials without performance verification.

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.
