What Should I Not Touch After a Sewage Backup?
Last updated October 25, 2026
The short answer
Avoid Contaminated Porous Materials
Porous items like carpeting, rugs, and upholstered furniture absorb sewage quickly. This makes them extremely difficult to clean and a primary source of lingering bacteria and mold. Even if they appear dry on the surface, harmful pathogens remain deep within the fibers. These materials are generally not salvageable and require professional removal to ensure the space is safe.
Drywall, wood paneling, and insulation are also porous and cannot be cleaned effectively once saturated. They act like sponges, trapping contaminated water and creating a hidden hazard within your walls. Attempting to save these materials often leads to persistent mold growth and structural issues. Professionals have the tools to assess and remove damaged building materials properly.
Do Not Handle Electrical Hazards
Never touch electrical outlets, switches, or appliances that are wet or near the sewage water. Water is a conductor, and contact can result in severe shock or electrocution. If the power is still on, do not enter the flooded area. Your first action should be to shut off the main electrical power at your breaker panel from a dry, safe location.
Leave all appliances, including water heaters, furnaces, and laundry machines, untouched. Internal components can be damaged and pose a shock risk even after the water recedes. A qualified electrician must inspect and certify any electrical system before you attempt to use it again. This is a critical safety step that protects you from hidden dangers.
Protect Your Personal Belongings
Personal items like clothing, books, and children's toys that have been in contact with sewage are contaminated. Handling them without proper protection spreads germs to other areas of your home. While some non-porous items like glass or metal may be disinfected, the decision should be left to a professional assessment. Sentimental items require special handling protocols to attempt restoration.
Paper documents, photographs, and cardboard boxes are particularly vulnerable. They are often unsalvageable due to rapid deterioration and staining. Attempting to dry them yourself can cause further damage and will not eliminate the health risks. A restoration professional can advise on what might be saved through specialized drying and cleaning techniques.
Stay Away from Affected Floors and Cabinets
All flooring surfaces, whether hardwood, laminate, or tile, are contaminated and should be avoided. Sewage water seeps into cracks, under planks, and beneath flooring, creating a widespread biohazard. Walking on these surfaces can track contaminants to other parts of your home and expose you directly to harmful microorganisms. Proper cleanup involves extensive extraction and disinfection by trained pros.
Kitchen and bathroom cabinets, especially those with particleboard or wood construction, absorb water from the bottom up. The contaminated water compromises their structure and makes them unsafe for storing items. Do not open or empty these cabinets yourself, as disturbing them can release contaminated particles into the air. They often need to be removed to allow for proper drying and disinfection of the space behind them.

- Kitchen base cabinets and vanities
- Bathroom vanity cabinets
- Subflooring and underlayment
- Area rugs and floor mats
Understanding the Health Risks
Sewage contains bacteria, viruses, parasites, and fungi that can cause serious illnesses. Direct contact or inhalation of airborne particles can lead to gastrointestinal infections, skin rashes, and respiratory problems. This is why avoiding the area and not touching anything is the safest immediate action. If you must be nearby, wear waterproof gloves, boots, and an N95 respirator as a minimum barrier.
The humid subtropical climate with hot humid summers and cool winters in areas like Germantown can accelerate mold growth within days. This adds a secondary health hazard to the initial contamination. If you start to feel unwell with symptoms like nausea or coughing, see a doctor and inform them of the sewage exposure. Local water damage pros are equipped to handle these specific biohazard scenarios safely.

Can I clean the sewage myself with bleach?
Using bleach on a large sewage spill is not recommended. It is ineffective against many sewage pathogens and can create dangerous fumes when mixed with other chemicals. Proper cleanup requires industrial-grade antimicrobials and specialized equipment to ensure all contaminants are neutralized. This is a job for professionals with the right safety gear and training.
What should I do first after discovering a backup?
Ensure everyone's safety by evacuating the affected area. Avoid contact with the water and shut off the main electrical power if it is safe to do so. Contact a plumber to stop the source if possible, and then call local water damage pros for emergency sewage cleanup. Document the damage for your insurance company with photos from a safe distance.
Will my insurance cover sewage cleanup?
Coverage depends on the cause of the backup and the specifics of your homeowner's policy. Sudden, accidental events like a pipe break may be covered, while neglect or maintenance issues often are not. Policies vary, and your insurer decides what is covered. Contact your agent promptly to start the claims process and discuss your coverage.
