Sewer Backup Questions Answered for Davenport, WA
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.
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.
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 sewage backs up through a shower or tub?
Treat it as raw sewage. Keep people out of the bathroom, stop using the fixture and call for cleanup. The liquid can reach under flooring and into walls, so a crew checks beyond the visible puddle.
Can carpet be saved after a sewage backup?
Usually not. Carpet and padding soak up Category 3 water and cannot be reliably made safe, so they are cut out and discarded. Hard surfaces, sealed wood and items in closed containers can often be cleaned and kept.
Should I call a plumber or a cleanup company first?
If sewage is still coming up, a plumber may need to stop the source. If sewage is already on the floor, a cleanup team can start containing it at once. Many property owners call both, and it does not matter much which is first. Sewer backup companies and plumbers often work one after the other on the same job.
