The short answer

Protect Yourself First

Sewage contains bacteria, viruses, and other pathogens that can cause illness. Before you touch anything, put on waterproof boots, heavy rubber gloves, and a respirator or N95 mask. Wear long sleeves and pants to keep skin covered. Open windows and doors to let fresh air move through the space, and keep children and pets away from the area.

Turn off electricity in the affected rooms at the breaker panel if water is near outlets or appliances. If you feel unwell at any point, stop and see a doctor. If the backup is large or you have health concerns, the pros can handle the cleanup with proper equipment and training.

Remove Contaminated Items

Start by removing solid waste and any items that soaked up sewage, such as carpet, padding, drywall, and upholstered furniture. Place them in heavy plastic bags and seal them tightly. Dispose of these materials according to your local waste rules. Do not try to salvage porous items because they can harbor bacteria and odors.

For items you want to keep, like hard plastic or metal, rinse them with clean water and set them aside for later disinfection. Be cautious when lifting heavy or soaked objects, as they can be very heavy and may contain sharp edges. If you are unsure about what to keep, it is safer to discard it.

  • Wear boots, gloves, and a respirator
  • Open windows for ventilation
  • Turn off power to affected areas
  • Remove solids and soaked porous items
  • Bag contaminated materials securely
  • Keep children and pets away

Clean and Disinfect Surfaces

After removing debris, wash all hard surfaces with hot water and a heavy-duty detergent. Use a mop or scrub brush to work the soap into floors, walls, and any fixtures. Rinse thoroughly with clean water. Then apply a disinfectant solution, following the label instructions for contact time. Common options include a bleach solution of one cup bleach per gallon of water.

Pay special attention to baseboards, cracks, and corners where sewage can hide. Let the disinfectant sit for the recommended time, then rinse again if needed. Dry the area completely using fans or a dehumidifier. If you have a sump pump or wet vacuum, use it to remove standing water before cleaning.

Dry and Prevent Mold

Sewage leaves moisture that can lead to mold growth within days. After cleaning, dry the area thoroughly. Use dehumidifiers, fans, and open windows to speed up drying. Remove baseboards and cut out wet drywall if necessary, because trapped moisture can cause structural damage and mold. If you see mold later, a mold professional can assess and treat it.

Check for hidden moisture in wall cavities and under flooring. If you live in Newark, keep your shutoff valve location written down so you can act quickly in a future backup. For extensive drying and restoration, the pros can use specialized equipment to dry structures and prevent long-term issues.

Know When to Call Pros

Some sewage backups are too large or dangerous for a homeowner to handle alone. If the backup covers more than a small area, involves sewage from a toilet or floor drain, or affects multiple rooms, call the pros. They have protective gear, industrial fans, and cleaning agents that are not available to most homeowners.

Also call pros if the sewage has soaked into drywall, insulation, or hardwood floors, as these materials often need removal and replacement. Professional cleanup usually involves extraction, disinfection, and drying to reduce health risks. They can also help with contents cleaning and restoration for salvageable items. Policies vary, and your insurer decides what is covered. If you have questions about your policy, check your policy or ask your insurance company.

Frequently asked questions

Can I clean up sewage backup myself?

You can handle small spills if you wear proper protection and follow safety steps. For large backups or if sewage has soaked into drywall and flooring, it is safer to call the pros. They have the right equipment and experience to clean thoroughly.

What should I do with soaked carpet and furniture?

Discard porous items like carpet, padding, and upholstered furniture because they absorb sewage and cannot be fully cleaned. Seal them in plastic bags and dispose of them properly. Hard, non-porous items can sometimes be cleaned and disinfected if you act quickly.

How long does it take to dry after sewage cleanup?

Drying time depends on the extent of water damage, humidity, and airflow. With fans and dehumidifiers, surfaces may dry in a few days, but hidden moisture can take longer. Professional drying equipment can speed up the process and help prevent mold growth.
