Common Questions
What homeowners ask
What is a C-36 plumbing license?
C-36 is the California Plumbing Contractor license. Any plumber performing work over $500 must hold an active C-36 license. We verify every contractor against the live CSLB database before matching you.
When should I repipe my home?
If your home has galvanized steel pipes (common in homes built before 1970), recurring leaks, rusty water, or low water pressure, repiping with copper or PEX is worth considering. A licensed plumber can inspect your current pipes.
Do I need a permit for a water heater replacement?
Yes, in most California cities a water heater replacement requires a permit and inspection. Your C-36 licensed plumber handles the permit application. The inspection ensures proper pressure relief and venting.
Do you have 24/7 emergency plumbing service?
Yes. We can connect you with C-36 licensed plumbers who offer 24/7 emergency service for burst pipes, major leaks, and sewer backups. Use the bilingual AI assessment to describe your emergency and get matched immediately.
