Sewage Cleanup Frequently Asked Questions in Mountlake Terrace, WA
Does homeowners insurance cover sewage backup?
Often only with an added endorsement. Many standard policies treat sewer or drain backup separately from sudden water damage. Call your insurer before cleanup begins, take photos and keep receipts, and ask what they need to see.
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.
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.
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 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.
Do plumbers clean up sewage?
Plumbers usually clear the blockage or repair the pipe, but most do not remove contaminated materials or disinfect the space. A sewage cleanup company picks up where the plumber stops, and the two jobs often happen in sequence.
