The Black Water Extraction (Category 3) Process in Mercer Island, WA
Contaminated Carpet Water Extraction
Carpet and pad that absorbed sewage or floodwater cannot be safely cleaned. They are cut out, bagged and removed from the home.
Toilet Overflow Water Removal
Toilet water that has spread across a floor is treated as contaminated. It is extracted, and floors, baseboards and lower walls are disinfected.
Storm Sewer Flood Water Removal
After storm sewer flooding, mud and debris are cleared before floors and walls are cleaned, disinfected and dried.
Black Water Drying
Air scrubbers filter the air during drying, which helps with odor and dust from removal work.
Sewage Damage Report for Insurance
Documentation starts before cleanup, with photos of the water level and affected rooms, and continues through final drying.
