Mallard Plumbing
Knowledgeable reliable plumber
Good service, fair price, have used for many years.
Consider Capelli Plumbing if...
- ✓ You want predictable service delivery with documented patterns of prompt response, same-day or next-day scheduling, and clear communication throughout the project from initial contact to completion.
- ✓ Your project involves standard residential plumbing work like water heater replacement, drain cleaning, fixture installation, or gas line work where nine years of experience is fully adequate.
- ✓ You value technicians who explain issues and pricing upfront before proceeding, respect your home with proper cleanup, and take time to educate you about your plumbing systems.
- ✓ You prefer working with a contractor whose recent customer experiences are transparent and consistently positive across diverse project types.
Consider Mallard Plumbing if...
- ✓ Your project involves an older Oakland home with potentially outdated or unusual plumbing configurations where 43 years of trade exposure might help diagnose hidden complications that newer contractors haven't encountered.
- ✓ You're willing to invest time asking detailed questions about current crew tenure, recent project references, and what specifically drives the mixed feedback to determine if the company's current operations match its longevity.
- ✓ You have a complex commercial or multi-unit residential project where decades of varied experience across different property types could provide advantages.
- ✓ You're already familiar with Mallard through previous work or referrals that give you confidence beyond what public information reveals.
Questions to Ask Before Hiring
- → Ask Mallard specifically what drives the mixed customer feedback and request references from projects completed in the past six months that match your scope of work.
- → Ask Mallard how long their current lead technicians and office staff have been with the company to understand if the 43-year history reflects current team experience.
- → Ask both companies for detailed written estimates that break down labor, materials, and timeline so you can compare not just price but project approach.
- → Ask about warranty terms on both labor and materials, and what the process looks like if issues arise after project completion.
The Bottom Line
For most homeowners needing plumbing work this week, Capelli Plumbing is the clearer choice. Nine years is ample experience for residential plumbing projects, and their documented track record of prompt response, professional service, clear communication, and respect for property gives you predictable expectations. Mallard's 43-year history is impressive on paper, but mixed customer feedback without specific details creates uncertainty about current service quality that you'd need to resolve through direct investigation. If you have an older Oakland home with potentially complex plumbing issues and time to thoroughly vet Mallard's current operations, their decades of exposure might prove valuable. Otherwise, go with the contractor whose recent performance you can actually verify.

Frequently Asked Questions
Potentially yes for truly unusual situations in older buildings, but nine years is fully adequate for the vast majority of residential plumbing work. The real question is whether Mallard's current crew carries that institutional knowledge, which the mixed feedback makes unclear. Capelli's documented experience across water heaters, sewer lines, gas work, and installations shows comprehensive capability for standard and moderately complex projects.
Without specific review details, mixed feedback could mean anything from pricing disputes to service quality issues to personality conflicts with individual customers. It doesn't automatically disqualify them, but it does mean you need to ask direct questions and check recent references yourself. The lack of transparency creates risk that Capelli's documented positive patterns don't carry.
Most Capelli customers consider pricing within market range for Alameda County, though some experience sticker shock. This likely reflects the reality that quality plumbing work in the Bay Area is expensive regardless of contractor. The key advantage is that Capelli explains pricing before proceeding, so you can make informed decisions rather than facing surprise bills.
Capelli is the safer choice for an emergency because their documented pattern shows same-day and next-day availability with prompt response times and clear communication. You know what to expect. With Mallard, you'd be hoping their current operations match their 43-year history, but the mixed feedback without details makes their emergency responsiveness uncertain.

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.
