Complete Black Water Extraction (Category 3) Protocols in Martha Lake
Sewage Backup Water Extraction
After a sewer backup, the water is pumped out, solids are removed, and every surface it touched is cleaned and disinfected before drying.
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.
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.
Contaminated Carpet Water Extraction
Once contaminated carpet is out, the subfloor is cleaned, treated and dried before any new flooring goes down.
Flooded Basement Sewage Cleanup
Below-grade spaces dry slowly, so after cleaning and disinfection, dehumidifiers run until walls and slab test dry.
Warning Signs You Need Black Water Extraction (Category 3)
Sewage Backup in Toilet or Sink
Sewage coming up through a toilet, tub or sink means the sewer line is blocked or overloaded.

Several drains gurgling or backing up at once usually means the main sewer line is blocked.

Basement water that smells like sewage or has debris in it is Category 3 and needs protective cleanup.

Sewage or standing dirty water in a crawl space needs extraction and disinfection before drying.
