How to choose a plumber in San Marcos
- Ask whether the quote is flat-rate or hourly, and whether there is a trip charge.
- For water heaters and re-pipes, ask about permits and inspections.
- Ask what the warranty covers and for how long.
Check the license: Contractors State License Board (CSLB). In California, most home improvement work above the state's small-job limit requires a CSLB license. Look the number up before you sign, and check that it is active and bonded.
