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...

J.J. Commercial Water Heaters
The best in the business! Rich and Jessie are amazing. The most honest and hardworking guys I know. You need it done they will always find a way to take care of the problem.
Consider Big Brothers Plumbing if...
- ✓ You need a full-service plumber who can handle multiple issues in one visit, not just water heater work, which is valuable for older homes where plumbing problems often come in clusters
- ✓ Same-day service and quick emergency response matter to you, which Big Brothers Plumbing has demonstrated consistently across numerous customer accounts
- ✓ You want transparency around pricing before work begins and detailed explanations of your options, which customers repeatedly cite as this company's strength
- ✓ You value seeing extensive customer feedback documenting how a contractor communicates, handles complications, and respects your property during service calls
Consider J.J. Commercial Water Heaters if...
- ✓ You have a commercial-grade water heater system that requires specialized expertise beyond typical residential equipment
- ✓ You prefer working directly with the owner rather than dispatched technicians, as J.J. Commercial Water Heaters features high owner involvement
- ✓ Your project involves complex commercial water heating requirements where their focused specialization provides value that justifies potentially higher service fees
- ✓ You're willing to request references directly since public review history is limited and want to verify their residential service experience before committing
Questions to Ask Before Hiring
- → Ask J.J. Commercial Water Heaters what percentage of their work is residential versus commercial, and request references from recent residential water heater projects similar to yours
- → Confirm J.J. Commercial Water Heaters' service call fee structure upfront and get a detailed written estimate, since their fees may be higher than typical residential plumbers
- → Ask Big Brothers Plumbing about their specific experience with your water heater type if you have commercial-grade equipment, to ensure their residential focus includes larger systems
- → Request from both contractors how quickly they can schedule non-emergency work and what their warranty covers on parts and labor
The Bottom Line
For most homeowners, Big Brothers Plumbing is the clearer choice. Their 10 years of licensing, extensive positive customer feedback, documented same-day service, and transparent pricing approach give you confidence in what to expect. They handle the full range of residential plumbing needs, which is valuable if your project uncovers additional issues. Choose J.J. Commercial Water Heaters only if you have commercial-grade equipment requiring specialized expertise or specifically want high owner involvement, but request residential references first and get detailed pricing in writing since their commercial focus may mean higher fees. If you need work done this week and want proven responsiveness, Big Brothers Plumbing's track record of same-day service makes them the more reliable option.

Frequently Asked Questions
For standard residential water heaters, Big Brothers Plumbing's broad residential experience and documented customer service approach likely serves you better. If you have a commercial-grade system in your home or a particularly large or complex setup, J.J. Commercial Water Heaters' specialization could be valuable, but ask for residential references first. Most homes don't require commercial-level specialization.
Big Brothers Plumbing's 10 years licensed versus 7 means they've encountered more unusual situations, older systems, and hidden complications that come with residential work. This experience gap matters most if your home is older, your plumbing has a history of issues, or you're dealing with an emergency where quick diagnosis is critical. For straightforward water heater replacements in newer homes, both have sufficient experience.
Their commercial focus means most clients are businesses that don't typically leave online reviews like homeowners do. This isn't necessarily a red flag, but it does mean you'll need to request references directly to assess their work quality, communication style, and how they handle residential customers. Ask specifically about residential projects when checking references.
While their same-day availability is a key strength, customers consistently mention transparent pricing discussions before work begins, suggesting they're not charging emergency premiums without disclosure. J.J. Commercial Water Heaters may actually have higher service call fees given their commercial focus. Get written estimates from both and compare the total project cost, not just hourly rates.

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.
