Consider Performance Plus Plumbing if...
- ✓ Your home was built before 2000 and may contain older piping, outdated venting, or legacy fixtures that require diagnosis from someone who worked with those systems when they were current
- ✓ You're dealing with water heater issues and want a contractor with manufacturer warranty authorization and specialized expertise in this specific equipment category
- ✓ You're in Livermore or eastern Alameda County where Performance Plus has operated continuously for over three decades, building deep local knowledge of regional plumbing configurations
Consider Capelli Plumbing if...
- ✓ You're in San Leandro or western Alameda County where Capelli maintains their established operation and local presence
- ✓ Your project involves straightforward residential plumbing work where 9 years of experience provides sufficient expertise for reliable completion
- ✓ Customer education is a priority—reviews specifically highlight Capelli technicians taking time to explain systems and issues in detail
- ✓ You value a contractor who has built repeat customer relationships over nearly a decade, indicating consistent service quality
Questions to Ask Before Hiring
- → For older homes, ask the contractor about their experience with your specific plumbing configuration and whether they've worked on homes from your construction era
- → Ask Performance Plus which water heater brands they hold warranty authorization for if your repair involves manufacturer coverage
- → Ask Capelli about their diagnostic approach for complex problems and whether they bring in senior technicians for unusual situations
- → Request references from projects similar to yours in scope and complexity, particularly if your work involves older infrastructure
The Bottom Line
For most homeowners, Performance Plus Plumbing's 32 years of licensed experience offers meaningful advantages over Capelli's 9 years, particularly for older homes where hidden complications commonly emerge and for water heater work where they maintain specialized expertise. Capelli is a legitimately experienced contractor who handles diverse residential plumbing successfully, making them a solid choice for straightforward projects or if you're located closer to their San Leandro base. However, if your home predates 2000, your project involves equipment requiring deep diagnostic skills, or you simply want the contractor most likely to have encountered your specific situation before, Performance Plus's three decades of institutional knowledge justify their selection. Both companies maintain proper licensing and insurance, so this decision comes down to experience depth rather than basic credibility.

Frequently Asked Questions
For straightforward repairs, both companies have sufficient expertise. The experience advantage becomes meaningful when what appears simple reveals underlying issues—a leaking faucet caused by corroded supply lines, or a running toilet symptomatic of main line pressure problems. Performance Plus's additional decades increase the likelihood they've diagnosed these complications before.
Performance Plus shows specialized water heater focus with manufacturer warranty relationships and extensive customer feedback specifically on this work. For older homes where venting configurations, clearance requirements, or code compliance may have changed multiple times since original installation, their 32 years of navigating these transitions provides meaningful advantage.
Nine years is genuinely experienced—not a new company. Capelli handles sewer line repairs and diverse residential projects successfully according to customer feedback. They're capable of major work, though Performance Plus's additional experience provides deeper institutional knowledge if unexpected complications arise during invasive projects.
Customer feedback indicates both companies deliver on prompt scheduling commitments, with same-day and next-day availability mentioned frequently for each. Response time appears comparable based on actual customer experiences, so this factor shouldn't drive your decision between them.

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.
