Sewer Backup Questions Answered for North Beacon Hill, Seattle, WA
How long does sewage cleanup take?
Small jobs may be finished in a day, while larger ones with tear-out, drying and odor treatment take longer. The time depends on the area affected and what had to be removed. The crew can tell you what to expect after assessing the space.
Can sewage backup make me sick even after it is cleaned up?
If the cleanup missed contaminated materials, germs and odor can linger. That is why crews remove porous materials, disinfect every surface they touched and inspect the work. Thorough removal is what lowers the risk.
What illnesses can raw sewage cause?
Sewage can carry germs such as E. coli, norovirus, hepatitis A and Giardia. They spread through skin contact, splashes and hand to mouth contact. Washing well and wearing protection reduce the risk, but removal by a crew reduces it most.
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.
What should I do right after a sewage backup?
Keep everyone out of the area, including pets, and stop using sinks, tubs and toilets that feed the pipe. Turn off power to wet areas only if it is safe. Then call a cleanup team and your insurer, and take photos before anything is moved.
What if the sewage came from a septic tank?
A septic overflow is cleaned as raw sewage, both inside any affected building and on nearby ground. Contaminated soil, materials and surfaces are handled and disinfected. A septic service may also need to empty or repair the tank.
