Customer Reviews
Fault Line Plumbing
Based on my experience I can 100% recommend Adam from FaultLine Plumbing. After a previous plumber with a different company left the job unfinished, Adam went above and beyond to ensure that I had wor...
I have worked with several technicians at Faultline Plumbing over the past 12 months and they have always done outstanding work. We have two tankless water heating units that have been giving us issue...
Beautiful group of people.
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...
Big Brothers Plumbing was great - friendly, timely, and able to quickly determine and solve the problem! Highly recommend!
Consider Fault Line Plumbing if...
- ✓ You have an existing service relationship with Fault Line or can reach them through a referral, bypassing the initial contact difficulties some prospective customers have experienced.
- ✓ Your plumbing project involves an older home with potentially complex issues where 29 years of diagnostic experience becomes valuable for identifying hidden problems.
- ✓ You need specialized ongoing maintenance for equipment like tankless water heaters and value technical expertise over rapid initial response.
- ✓ You're not working under urgent time pressure and can afford to be persistent with follow-up calls during the inquiry phase.
Consider Big Brothers Plumbing if...
- ✓ You need a plumber today or within hours for an emergency situation like a failed water heater or significant leak, where Big Brothers' documented same-day availability matters.
- ✓ You're a first-time homeowner or want thorough explanations about your plumbing systems and repair options before committing to work.
- ✓ Getting clear upfront pricing and transparent communication throughout the service process reduces your stress about unexpected costs.
- ✓ You value contractors who respect your property with details like shoe coverings and thorough cleanup, which appears consistently in Big Brothers' feedback.
Questions to Ask Before Hiring
- → For Fault Line: Ask what their current response time is for new customer inquiries and bids, and whether there's a direct contact who handles scheduling to avoid the communication gaps others have reported.
- → For Big Brothers: Ask about their experience with older homes in Livermore specifically, since their 10 years of licensing is solid but significantly less than Fault Line's 29-year history.
- → Ask both companies for references from projects similar to yours in scope and complexity, particularly if you have an older home with galvanized pipes or other legacy plumbing systems.
The Bottom Line
For most homeowners needing plumbing service this week, Big Brothers Plumbing is the clearer choice. Their documented same-day response, transparent pricing, and consistent communication reliability matter more than Fault Line's experience advantage for typical residential plumbing projects. Big Brothers' 10 years of licensing is entirely sufficient for water heater replacements, fixture installations, and drain clearing. Choose Fault Line only if you already have an established relationship with them, need specialized ongoing maintenance for complex equipment, or are tackling an older home renovation where their 29 years of diagnostic experience with legacy systems becomes genuinely valuable. Even then, be prepared to make multiple follow-up calls to secure their services. If you're facing an emergency or simply need a reliable contractor who will answer your call, Big Brothers eliminates the communication risk entirely.

Frequently Asked Questions
For a standard water heater swap in a newer home with accessible plumbing, both companies have sufficient experience. However, if your home was built before 1980 or has unusual configurations, Fault Line's three decades navigating Bay Area building codes and older plumbing systems provides meaningful additional expertise for diagnosing complications. Big Brothers' 10 years is still substantial for routine installations.
Technical expertise only helps if you can access it. Multiple customers report difficulty getting Fault Line to return initial calls, which is a real problem when you need service this week. Big Brothers consistently responds same-day and communicates transparently throughout the process. For most residential plumbing projects, Big Brothers' 10 years of experience is entirely adequate, and their operational reliability may matter more than Fault Line's additional 19 years.
Big Brothers Plumbing clearly excels at emergency response, with documented customer experiences of technicians arriving within hours for urgent issues like water heater failures and leaks. Their business model emphasizes same-day availability. Fault Line's communication challenges during the inquiry phase make them a poor choice when you need immediate service.
The data doesn't provide pricing comparisons, but customers specifically praise Big Brothers for transparent pricing discussions before work begins. Given Fault Line's veteran status, they may command premium rates, but you'd need to get quotes from both. Ask each company for detailed written estimates that break down labor and materials to compare accurately.

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.
