Sewage Backup Cleanup Questions

: Sewage backup is classified as Category 3 (black water) and contains E. coli, hepatitis A, Cryptosporidium, and other pathogens that can cause serious illness. Evacuate the affected area, avoid contact, and call restoration professionals immediately. Do not use sinks, toilets, or drains in the home until the system is cleared.
: Standard homeowners policies typically exclude sewage backup. However, many insurers offer a sewer backup rider (usually $5–15/year) that covers it. Check your policy declarations page specifically. If you have the rider, call your insurer before cleanup begins.
: Most residential sewage backup remediation takes 3–5 days: Day 1 extraction and decontamination; Days 2–4 drying and antimicrobial treatment; Day 5 post-remediation testing and clearance. Complex cases with structural damage take longer.
