STOP using all fixtures (toilets, sinks, showers, washer). Each flush adds to the basement. Open windows. Wear rubber boots if entering. Sewage carries bacterial hazards — don't track it through the house.
Step-by-step response
- 1Stop using water
No flushing, no washing, no showers. Anything that adds water makes the backup worse.
- 2Call your water utility if it's storm-related
If multiple homes on your block flooded at the same time, the city sewer mains are overflowing. Toledo: 419-936-2020. Findlay: 419-424-7113. They may issue a boil advisory or pump station diversion.
- 3Document for insurance
Photos before cleanup. Note time, weather conditions, what overflowed where. Sewer-backup coverage is a separate endorsement on most homeowners policies — verify yours. Findlay AE-zone homes need NFIP for full coverage.
- 4Call a plumber — emergency
Service call $79-150. Sewer cabling $185-385. Hydro-jet $385-685. Sewer-camera diagnosis $185-450. Spot repair $850-3,500. Full lateral replacement (clay-to-PVC) $4,500-12,000.
- 5Plan a backflow preventer
If you've had multiple sewer backups, install a backflow preventer ($400-2,500). Findlay floodplain homes: this is the single most important plumbing investment. See cost guide /cost/backflow-preventer-install-cost-findlay.

Frequently asked
Is it tree roots or just a soft clog?
A camera inspection ($185-450) tells you. Soft clogs (grease, paper) cable easily. Roots come back fast — root-foaming treatments help, but if you're rooting twice a year, plan a lateral replacement.
Is the cleanup covered by insurance?
Standard homeowners doesn't cover sewer backup. You need a 'sewer/drain backup' endorsement (typically $50-100/yr extra) — it covers cleanup + drying + replacement of damaged stuff. Findlay floodplain homes also need NFIP for storm-driven sewer backup.
What's a 'main-line' clog vs 'lateral' clog?
Lateral = your house's line, from house to street. Main = the city's line under the street. Lateral is yours to fix; main is the city's. The plumber's camera tells which. Findlay backups during heavy rain are often city-main overflows, not your lateral.
