The Black Water Extraction (Category 3) Process in Duvall, WA
Storm Sewer Flood Water Removal
Water from an overloaded storm sewer or street flooding carries soil, debris and contaminants. It is extracted and the affected areas are cleaned.
Black Water Drying
Drying comes last in black water work. Drying before contaminated materials are removed would leave contamination in place.
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.
Flooded Basement Sewage Cleanup
Sewage or floodwater in a basement is pumped out, contaminated drywall, carpet and insulation are removed, and concrete and framing are disinfected.
Contaminated Carpet Water Extraction
Once contaminated carpet is out, the subfloor is cleaned, treated and dried before any new flooring goes down.
When to Call for Black Water Extraction (Category 3) in Duvall
