Common questions

Is a license required for drain cleaning in California?

Contractor licensing rules are set by the CSLB. The simplest approach is to hire a licensed plumbing contractor and verify the license at cslb.ca.gov.

Should I get more than one quote?

For simple cleaning during a backup, speed often matters more. For repairs or replacements, a second opinion with its own inspection is reasonable.

What paperwork should I keep?

The invoice, any written findings, and the camera recording. Together they form your home's drain history.
