Sewer Backup Questions Answered for Downtown, Seattle, WA
How much does a sewer backup cleanup cost?
The price depends on how much sewage there is, how far it spread and which materials must be removed. A bathroom overflow costs less than a flooded basement. The team sets the price after seeing the space, and nothing is decided on a call alone.
How long does it take to get sick from raw sewage?
Symptoms such as stomach cramps, vomiting and diarrhea can start within hours or take a few days. Anyone with symptoms after exposure should contact a doctor. Children, older adults and people with weak immune systems are at higher risk.
How do I clean up a sewer backup?
Keep people and pets out, turn off power if water is near outlets, and avoid touching the sewage. Safe cleanup needs protective gear, extraction, removal of soaked materials and disinfection. For anything more than a small spill, a cleanup company is the safer choice.
What is Category 3 water, also called black water?
Category 3 water is the most contaminated level, and sewage is the standard example. It can carry disease-causing germs and should never be cleaned with household supplies alone. Flood water that touched sewage is treated the same way.
Why does drywall have to be removed after sewage?
Drywall is porous and holds contamination that can spread germs and odor long after the surface looks clean. Crews usually cut out wall board that sewage touched, and often take out a margin above the wet mark to reach clean material.
How do I clean sewage off concrete?
Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
