C.P.A Plumbing
No reviews available
Consider Allstar Plumbing if...
- ✓ You have an older home where plumbing problems may involve hidden complications like corroded pipes, outdated fittings, or code compliance issues that require experienced diagnosis
- ✓ You need emergency service and want documented evidence of quick response times and same-day availability
- ✓ You value being able to review feedback from dozens of previous customers who've used the company for similar projects
- ✓ Your project is complex or involves multiple systems like gas lines, water heaters, or whole-house repiping where veteran expertise reduces the risk of costly mistakes
Consider C.P.A Plumbing if...
- ✓ Your project is straightforward work in newer construction where complications are unlikely, such as a simple fixture replacement or basic drain clearing
- ✓ You specifically prefer working with a newer, smaller operation and are comfortable accepting higher risk in exchange for potentially lower pricing
- ✓ You're willing to serve as an early customer and can verify the contractor's background, training, and prior work experience before licensing independently
Questions to Ask Before Hiring
- → Ask C.P.A Plumbing for references from at least three completed projects similar to yours, and follow up by contacting those customers directly
- → Ask C.P.A Plumbing about the owner's background: How many years were they working in plumbing before getting their own license, and can they provide references from that period?
- → Ask Allstar Plumbing about their current availability and whether they can commit to your project timeline given their established customer base
The Bottom Line
Allstar Plumbing is the clearly safer choice for most homeowners. Their 29 years of continuous operation, documented customer satisfaction, and proven emergency response capabilities provide the reassurance you need when hiring someone to work on critical home systems. C.P.A Plumbing may be competent, but with only one year licensed and no customer reviews, you have no way to verify their work quality or reliability. Unless your project is extremely straightforward and you're comfortable being an early customer, Allstar's established track record justifies choosing them for your plumbing needs.

Frequently Asked Questions
Not necessarily. The owner may have worked for years as an employee or apprentice before obtaining their contractor license. However, without reviews or references, you have no way to verify their actual experience level or quality of work. Ask directly about their background and request verifiable references.
For complex projects, older homes, or emergency situations, yes. Three decades means they've handled nearly every scenario and can diagnose hidden problems that less experienced contractors might miss or misdiagnose, potentially saving you money on repeat service calls. For very simple work in newer construction, the experience gap matters less.
With only one year of licensing, they likely haven't completed enough projects yet to generate substantial online feedback. This means you're making a decision without the verification that reviews provide regarding quality, communication, pricing transparency, or how they handle problems. You'll need to rely entirely on references they provide directly.
Those protections cover liability and financial guarantees, but don't address competence or reliability. A contractor can be fully insured but still misdiagnose problems, take longer than necessary, or lack the experience to handle complications. Allstar's 29-year track record and customer feedback provide evidence of consistent service quality that C.P.A cannot yet demonstrate.

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.
