Sewage is Category 3 water under the IICRC standard. It carries bacteria and needs protective gear, removal of porous materials and disinfection.
Keep people and pets out
Do not wade through it, run the HVAC or use the drains. Open windows if it is safe and wait for a crew with protective equipment.
What gets thrown away
Carpet, pad, and drywall touched by sewage are generally removed. Hard surfaces are cleaned and disinfected, then the area is dried.
Clarify the cleanup scope
Tell the provider that sewage or drain backup is suspected when you call. Ask how they will assess affected rooms and contents, explain access restrictions and document the materials proposed for removal or cleaning.
Separate drain repair from restoration
Clearing a blockage or repairing a sewer line does not describe the cleanup of damaged rooms. Confirm who handles the drainage problem and who handles the affected flooring, walls and belongings. Ask whether each requires a separate agreement.
Discuss documentation and completion
Request an itemized scope for cleanup, disposal, any drying and subsequent repairs. Ask what completion checks and records will be supplied and when the provider expects affected spaces to be available for use.
What to do in the first hour
- Stop the water. Close the main shutoff valve or the fixture valve.
- Kill power to wet areas at the breaker, if you can reach it without standing in water.
- Move valuables up. Photos, electronics and documents off the floor.
- Photograph everything before anything is moved, for your insurance claim.
- Call your insurer to open a claim and note the claim number.
- Call a restoration crew so extraction starts within hours, not days.
Frequently asked questions
Who pays for a sewer backup?
Many homeowner policies exclude it unless you carry a sewer backup endorsement. Check your policy.
Can I clean it myself?
Small toilet overflows maybe. Basement-scale backups need professional gear because of health risks.
