Questions to ask your adjuster / provider
- What documentation do you need (photos, receipts, moisture readings)?
- Is cleanup/disinfection covered, or only repairs?
- Do you require pre-approval for work above a certain amount?
- What is the deductible and any sub-limits for sewer backup?
Common mistakes to avoid
- Delaying mitigation — it can increase damage.
- Throwing away items before documenting them.
- Approving work without a written scope.
- Focusing only on “snaking” without addressing recurring root cause.
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).
