When to call professionals

Local notes for California
- Older lines and root intrusion are common causes of backups—camera inspection can help pinpoint the source.
- Heavy rains can overwhelm drains; ask about prevention options like backwater valves (where applicable) and maintenance schedules.
- If cleanup is needed, prioritize proper containment, removal, and sanitization (not just odor masking).
