Can I Clean up After a Sewage Backup by Myself?
Last updated October 31, 2026
The short answer
Health Risks of Sewage
Sewage contains bacteria, viruses, and parasites that can cause serious illness. Touching it without protection can lead to infections, respiratory problems, or stomach issues. The longer sewage sits, the more it soaks into porous materials like drywall, wood, and carpet. Even after the visible mess is gone, germs can remain.
You should not attempt cleanup if you have open wounds, a weakened immune system, or respiratory conditions. Children and pets should stay far away. If you feel unwell during or after any cleanup, see a doctor. The pros have the training and equipment to handle this safely, which is why most homeowners call them.
What You Need to Protect Yourself
If you decide to attempt a very small cleanup, you need the right gear. Wear rubber boots, heavy-duty gloves, and goggles. Use an N95 respirator or better, not a cloth mask. Cover your skin with long sleeves and pants. Have a trash bag for contaminated items and a spray bottle with a bleach solution or a disinfectant labeled for sewage.
Do not use a regular household vacuum or mop for sewage. These can spread germs into the air and contaminate more areas. You also need to avoid mixing bleach with ammonia, which creates toxic fumes. If you feel unsure about your safety, stop and call the pros. Your health is not worth the risk.

When You Should Call the Pros
Call the pros for any sewage backup that covers more than a small area, has soaked into drywall or carpet, or has been present for more than a few hours. The pros have industrial pumps, vacuums, and drying equipment that you cannot rent easily. They also know how to dispose of contaminated materials properly.
The pros will remove standing water, clean and disinfect all affected surfaces, and dry the area thoroughly. They may need to remove sections of drywall or flooring that cannot be saved. This work is not something a homeowner can do safely, especially in a humid climate like Quincy, where moisture lingers.
Steps to Take Right Now
First, shut off the water source if you can and turn off the electricity in the affected area if it is safe. Do not walk through the sewage with bare feet or open shoes. Open windows for ventilation, but do not use fans that could blow contaminated air around. Keep children and pets away from the area.
Remove any items you can safely lift and place them in a separate area. Do not try to salvage porous items like pillows, mattresses, or stuffed toys. They are nearly impossible to clean thoroughly. Write down the shutoff valve location if you live in Quincy, so you are ready in the future.
What the Pros Usually Do
The pros start by extracting all standing water and contaminated solids. They then clean every affected surface with disinfectants, often using hot water extraction. After that, they set up dehumidifiers and air movers to dry out walls, floors, and contents. This process can take several days, depending on how much material is affected.
They also check for hidden moisture in walls and under floors, which can cause mold growth later. If the backup affected carpet or upholstery, the pros may clean it on site or remove it for off-site cleaning. In some cases, they need to remove and replace drywall and insulation. The cost depends on the extent of the damage and the materials involved.

Can I dry out the area with a fan?
A fan can help, but only after the sewage is removed and the area is disinfected. Using a fan before that can spread airborne germs. Even after drying, porous materials may still harbor bacteria, so replacement is often safer.
Is it okay to use bleach on all surfaces?
Bleach works on hard, non-porous surfaces, but it can damage some materials and does not penetrate porous ones. It also cannot be mixed with other cleaners. Use a disinfectant labeled for sewage on surfaces that can be saved.
What should I do with contaminated items?
Place them in heavy-duty trash bags and seal them tightly. Do not donate or try to wash them. Check with your local waste authority for disposal rules, as some areas have specific guidelines for sewage-contaminated waste.
