The Black Water Extraction (Category 3) Process in Snohomish, WA
Flooded Basement Sewage Cleanup
Below-grade spaces dry slowly, so after cleaning and disinfection, dehumidifiers run until walls and slab test dry.
Septic Tank Backup Cleanup
When a septic system backs up into the house, wastewater is extracted, contaminated materials are removed and the area is disinfected.
Sewage Backup Water Extraction
Sewage backups need extraction because the water carries bacteria and spreads contamination into flooring and walls the longer it sits.
Toilet Overflow Water Removal
An overflowing toilet can soak the subfloor and the ceiling below. Both are checked, and contaminated drywall is removed and replaced.
Black Water Drying
After cleaning and disinfection, air movers and dehumidifiers dry the structure, with readings taken daily until each area is normal.
