Detailed Black Water Extraction (Category 3) Methods for Union Hill
Black Water Drying
Drying comes last in black water work. Drying before contaminated materials are removed would leave contamination in place.
Sewage Backup Water Extraction
Sewage backups need extraction because the water carries bacteria and spreads contamination into flooring and walls the longer it sits.
Contaminated Carpet Water Extraction
Once contaminated carpet is out, the subfloor is cleaned, treated and dried before any new flooring goes down.
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.
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.
Signs of Black Water Contamination in Union Hill Homes
Visible Sewage in Crawlspace
Sewage or standing dirty water in a crawl space needs extraction and disinfection before drying.
Persistent Dampness After Flood
Areas that stay damp and smell after a flood still hold contaminated water in floors or walls.
Septic Tank Backup in Yard
Soggy ground, odors or sewage above the septic tank or drain field point to a septic failure.
Storm Drain Water in Garage
Water that flowed into the garage from the street or storm drain carries soil and contaminants.
