The team asks what happened, where the sewage is and who uses the space, then plans the right crew and equipment.
Wastewater is taken out of the building, and standing liquid in crawl spaces or low corners is cleared.
Contaminated drywall, trim and flooring are removed to clean material, and waste is sealed for proper disposal.
Remaining surfaces are washed and disinfected, and odor is removed at its source rather than covered up.

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.
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.
Yes. Commercial sewage cleanup in restaurants, offices, shops and apartment buildings follows the same biohazard steps, with added attention to keeping part of the building usable and to documentation for managers and insurers.
Yes. Raw sewage is Category 3 contamination and can carry bacteria, viruses and parasites. That is why cleanup crews wear protective gear and remove porous materials instead of just drying them.
A very small spill on a hard floor can be handled with gloves, boots, eye protection and a disinfectant used by label directions. Anything that reached carpet, drywall or a large area needs professional cleanup, because hidden contamination is hard to see.
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.
