Step-by-Step Instructions
Verify C-36 License
California requires plumbers to hold a C-36 plumbing license. Verify at https://www2.cslb.ca.gov/onlineservices/checklicenseII/CheckLicense.aspx with the license number.
Check Insurance
Plumbers should have General Liability ($1M minimum) and Workers Comp. Ask for certificate of insurance. Don’t hire without.
Read Reviews Carefully
Look for: detailed reviews mentioning specific work done. Beware: 5-star reviews from accounts with only 1 review (often fake). Cross-reference Yelp + Google + BBB.
Pricing Red Flags
Watch for: “Today only” pricing, refusing to provide written quote, dramatically lower than competitors (often missing essential work), cash-only insistence, demand for upfront full payment.
Green Flags
Licensed and insured. Written quotes before work. Flat-fee pricing rather than hourly meter. Pulls permits when required. Warranties workmanship for 30+ days. Has been in business 5+ years. Real reviews from real customers.
In LA, the “scammer plumber” pattern is well-documented. They go door-to-door after rains or earthquakes, claim to have spotted plumbing damage, demand cash payment for “emergency” work that’s not needed. Never engage with door-to-door plumbers. Always verify licensing online.
Don’t pay full upfront
Standard practice: deposit (10-30%) to start, balance on completion. Anyone demanding 100% upfront is a red flag.
Real Scenarios from Our LA Service Calls
Avoided $4,500 scam
Homeowner caught a door-to-door “plumber” trying to charge $4,500 for “emergency repipe” that wasn’t needed. Verified license number was fake. Reported to CSLB. Got a quote from licensed plumber for actual work needed: $1,200.
When to Call a Plumber Instead
DIY isn’t always the right call. Bring in a licensed plumber if any of these apply:
- You’ve done research and found qualified plumber
- Need second opinion on quote
- Reporting unlicensed activity
Frequently Asked Questions
How do I verify a license?
CSLB website. License number + name confirmation in 30 seconds.
Cash-only plumbers?
Red flag. Reputable contractors accept multiple payment methods.
How much should service call cost?
$89-$185 in LA for diagnostic visit. $0 sometimes when work is contracted.
Are licensed plumbers worth more than handymen?
For permitted work or warranty needs, absolutely. For minor handyman tasks, a competent handyman is fine.
How do I know quote is fair?
Get 2-3 quotes for same work. Variance under 30% = competitive. Outliers either too cheap (missing work) or too expensive (overcharging).
