Customer Reviews
Big Brothers Plumbing
Chuck at Big Brothers Plumbing did an excellent job. We had a huge leak and needed help fast. Also, Ashton was very helpful in relaying our information to Chuck and sent him out the same day.
Called in to Big Brother because our relatively new Navien tankless heater stopped working late last night. After setting up a same day appointment, Sarai followed up with me and asked me to check a f...

Precise Plumbing
Jay, was not only quick to respond to my messages late at night but came early the following day for an estimate on a mothers day. When he arrived, he was very knowledgeable and prepared to do the ser...

I was told by another plumber that I had a broken sewer pipe under the slab of my house. They quoted me $11,000. I called Precise Plumbing and spoke with Jay. He convinced me that he is an experienced...
Consider Big Brothers Plumbing if...
- ✓ You need workers compensation coverage in place to protect yourself from liability if a plumber is injured at your property, which is standard protection Big Brothers provides
- ✓ Your project is straightforward residential work like water heater replacement, faucet installation, toilet repair, or garbage disposal service where their documented experience is strong
- ✓ You value detailed pricing transparency upfront and educational explanations about your plumbing system, which customers consistently mention
- ✓ You prefer a company with multiple technicians who can handle high call volume while maintaining same-day availability
Consider Precise Plumbing if...
- ✓ You have a complex diagnostic situation like sewer line problems, under-slab leaks, or need a second opinion on an expensive quoted repair where their 15 years and diagnostic expertise provide significant value
- ✓ You're comfortable verifying your homeowner's insurance covers contractor injuries and are willing to accept the workers comp gap for access to veteran-level expertise
- ✓ You want high owner involvement on your project, which typically means the experienced contractor handles your work directly rather than delegating to newer technicians
- ✓ Your situation requires weekend or holiday service for estimates, an area where Precise Plumbing shows documented flexibility
Questions to Ask Before Hiring
- → For Precise Plumbing: Ask specifically about liability coverage and confirm with your homeowner's insurance whether contractor injuries are covered if workers comp isn't carried by the plumber
- → For Big Brothers Plumbing: Ask for references from diagnostic projects similar to yours if you have a complex sewer or under-slab issue, since their documented experience emphasizes standard repairs
- → For both: Ask who will actually be performing the work—the owner or crew members—and how long that person has been doing plumbing work
The Bottom Line
If you need standard residential plumbing work and want full insurance protection without liability concerns, Big Brothers Plumbing is the clearer choice—their 10 years provides solid experience for water heaters, fixtures, and routine repairs, and their workers comp coverage protects you from financial risk. Choose Precise Plumbing only if you have a complex diagnostic situation where their 15 years of veteran expertise and documented second-opinion value justify accepting the workers comp gap, and only after confirming your homeowner's insurance covers contractor injuries. For most homeowners, the insurance protection Big Brothers provides outweighs the experience advantage Precise Plumbing offers, unless you're dealing with a particularly complicated diagnostic challenge that demands veteran-level troubleshooting skills.

Frequently Asked Questions
Yes, it matters regardless of project size. If a plumber falls off a ladder or gets injured in your crawl space, you could face a lawsuit or medical claims if they lack workers comp coverage. Your homeowner's insurance may or may not cover this exposure—many policies exclude it or have limits. The risk exists on every job, not just complex ones.
For complex diagnostic work like sewer line issues or mysterious leaks, those additional 5 years represent hundreds more problem scenarios encountered and solved. For straightforward replacements like a water heater or faucet, the practical difference is minimal. If your situation involves troubleshooting rather than simple replacement, the veteran experience matters significantly.
Precise Plumbing has specific customer feedback about providing second opinions that came in significantly lower than initial quotes, particularly on complex sewer work. Their 15 years and diagnostic focus suggest they're equipped to challenge overpriced estimates. However, you'll need to weigh that expertise against the workers comp concern for your specific risk tolerance.
Both demonstrate quick response capability according to customer feedback. Big Brothers may have more scheduling flexibility due to multiple technicians, while Precise Plumbing's high owner involvement could mean occasional delays when the owner is committed to another job. For true emergencies, ask about current availability when you call rather than relying on general same-day promises.

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.
