When sewage backs up in your Monte Sereno property, call Monte Sereno Biohazard Cleanup Help for a crew that treats it as a Category 3 biohazard. The team removes the sewage, discards contaminated materials and disinfects the affected area in Santa Clara County with EPA-registered products.

With a Very High river flood risk rating from FEMA for Santa Clara County, flood events here can mix floodwater with sewage, which is treated as Category 3 contamination.

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.
Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.
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.
The smell comes from the contamination, so the fix is removing sewage and soaked materials first, then disinfecting and deodorizing. Air fresheners only cover it. If the odor persists, hidden material such as subfloor or insulation may still hold sewage.
Common signs include a sewer smell in the yard or crawl space, soft or damp ground near the foundation, gurgling drains and slow drains in several fixtures at once. A plumber can confirm the leak. Once it is found, a cleanup team can take care of the contaminated soil, materials and odor.
A cleanup team can start with a safe plan as soon as you call.
