The short answer
Sewage backup cleanup in California runs $4,000 to $12,000 for typical residential events. Severe whole-floor backups can reach $20,000-plus. Most homeowners policies don't cover sewage backup unless you have the specific endorsement. The cost is driven by required PPE, full demolition of porous materials, and regulated waste disposal.

How the claim flow works
- Call us first. We dispatch and start mitigation. Your policy requires immediate action to limit damage.
- We document on arrival. Moisture readings, photos, scope of work. The same evidence package adjusters use.
- You file the claim. Or we help. Most carriers will speak directly to our office with your authorization.
- Billing is agreed with you upfront. Whether your carrier pays the provider directly depends on your policy — dispatch explains the options before work starts.
Time-sensitive: California policies have "duty to mitigate" language. If you wait too long to call a restoration company, the carrier can deny part of the claim for damages that spread during your delay. Call within 24 hours of discovery.
