Sewage Backup Cleanup in Leawood, KS

Sewage carries bacteria, viruses and parasites, so there is no gray area. A backup through a basement floor drain, a toilet or a shower drain is treated as Category 3 water from the very start, no matter how clean it looks.

How Category 3 cleanup works

• Containment and PPE: the work area is sealed with plastic and crews wear respirators, gloves and suits
• Removal: carpet, pad, drywall and insulation the sewage touched are cut out above the waterline
• Cleaning: hard surfaces are scrubbed, and an EPA-registered antimicrobial is applied and left for its full dwell time
• Drying: framing and concrete are dried with dehumidifiers and air movers until readings match a dry reference

Why sewage backs up in Johnson County basements

Some Johnson County homeowners see basement flooding when extremely heavy rain backs up the sewer system, and the lowest opening in the house, usually the floor drain, is where it shows first. Roots and grease in an older private sewer lateral cause backups in dry weather too. On July 25, 2025, a 24-inch forcemain break near 87th Street and Mission Road led county health officials to warn residents to avoid contact with standing water nearby.

What to do before the crew arrives

Keep children and pets away from the area, do not run water or flush toilets and do not try to mop sewage with household tools. Photograph the backup for the claim. If floodwater from outside is involved too, Ready.gov flood safety and National Weather Service flood safety cover staying safe around contaminated water. Wider lower-level losses are covered under basement flooding cleanup.
