FAQ for Black Water Extraction (Category 3) in Daly City
Why is documentation important for sewage damage?
Sewage claims depend on the cause and policy add-ons. Photos, removal lists and readings give the adjuster what they need.
What happens during the black water drying process?
After contaminated materials are removed and surfaces disinfected, air movers, dehumidifiers and air scrubbers dry the structure.
What safety measures are used during extraction?
Protective gear, plastic containment, controlled air pressure and air scrubbers to keep contamination in the work area.
How is storm sewer flood water different from a pipe leak?
It carries soil, debris and contaminants from outside, so it is treated as Category 3 rather than clean water.
Does flood water from outside become black water?
Yes. Outside floodwater picks up sewage, chemicals and soil, so it is treated as Category 3.
