Sewage flooding, typically occurring in the basement or bathroom, is a critical problem that needs to be addressed immediately. While there are minor flooding incidents that you can tackle yourself, sewage flood cleanup involves several risks that would not make it DIY-friendly. If you’re considering cleaning up sewage flooding yourself, you may put your health, home, and wallet at risk.
10 Risks of DIY Sewage Flood Cleanup in Your Home
DIY sewage flood cleanup in your home can pose significant risks to your health and safety if not handled properly. Here are some of the key risks:
1. Exposure to Contaminants:
Sewage water contains a variety of harmful contaminants, including bacteria, viruses, parasites, and toxic chemicals. Direct contact with sewage water or inhalation of sewage fumes can lead to gastrointestinal illnesses, skin infections, respiratory problems, and other serious health issues.
2. Spread of Disease:
Sewage water can carry pathogens such as E. coli, Salmonella, Hepatitis A, and norovirus, which can cause severe illnesses. Improper cleanup techniques can result in the spread of these disease-causing organisms to other areas of your home, increasing the risk of illness for you and your family.
3. Mold Growth:
Sewage water can create ideal conditions for mold growth, especially in porous materials like drywall, carpeting, and insulation. Mold can exacerbate respiratory problems, cause allergic reactions, and damage the structural integrity of your home. Inadequate cleaning and drying of affected areas can lead to persistent mold problems.
4. Structural Damage:
Sewage floods can cause significant damage to your home’s structure and contents. The water can weaken building materials, corrode metal surfaces, and warp wooden structures. If not properly addressed, sewage water can seep into walls, floors, and ceilings, leading to long-term structural issues and costly repairs.
5. Electrical Hazards:
Sewage floods pose a risk of electrical hazards, especially if the water has come into contact with electrical outlets, appliances, or wiring. Attempting to clean up sewage water without properly shutting off the electricity to affected areas can result in electric shocks, fires, and other dangerous situations.
6. Chemical Exposure:
DIY Sewage Flood may contain hazardous chemicals from household cleaners, industrial pollutants, and other sources. Direct contact with these chemicals can cause skin irritation, chemical burns, and other adverse health effects. Additionally, mixing different cleaning products during the cleanup process can produce toxic fumes and reactions.
7. Legal and Insurance Issues:
DIY sewage cleanup may not meet the standards required by local regulations and building codes. Failure to properly clean and disinfect your home after a sewage flood could result in fines, penalties, and legal liabilities. Moreover, insurance companies may deny claims or provide limited coverage for damages resulting from improper cleanup procedures.
8. Cross-Contamination:
Improper handling of sewage water during cleanup can lead to cross-contamination of clean areas in your home. Without appropriate containment measures, contaminated water can spread to unaffected areas, increasing the scope of the damage and posing additional health risks.
9. Respiratory Issues:
Sewage water releases foul odors due to the presence of decomposing organic matter and gases such as methane and hydrogen sulfide. Prolonged exposure to these odors can cause respiratory irritation, headaches, dizziness, and nausea. In severe cases, it can lead to respiratory distress and exacerbate existing respiratory conditions like asthma.
10. Psychological Stress:
Dealing with a sewage flood and its aftermath can be emotionally challenging. The disruption to your home, potential loss of belongings, and concerns about health and safety can lead to significant stress and anxiety. DIY cleanup efforts may exacerbate these feelings if you’re not equipped to handle the situation effectively, leading to prolonged psychological distress for you and your family.
Considering these additional risks, it’s clear that DIY sewage flood cleanup is not worth the potential consequences. Seeking professional assistance ensures thorough cleanup, minimizes health hazards, and helps restore your home to a safe and habitable condition.
Health Risks of DIY Sewage Flood Cleanup
Sewage consists of greywater (from utilities like sinks, tubs, showers, and dishwashers) or worse – black water. It’s the water used to flush toilets mixed with the human waste that it flushes away. Sewage backups in your home can result from different causes – clogs in the home’s drain pipes, tree roots, damaged sewer lines, and more.
Sewage, especially black water, contains contaminants ranging from parasites and viruses to bacteria and fungi. Contact with sewage without wearing personal protective equipment (PPE) and following proper procedures is a serious threat to your health. There’s the risk of contracting over a dozen diseases, such as hepatitis A and encephalitis.
Mold growth is another risk when attempting DIY sewage cleanup. Mold exposure can worsen allergy and asthma symptoms, especially in children and people with compromised immune systems. Flooding provides ideal conditions for mold to develop as it only needs moisture, organic material, and optimal temperature. What’s worse – it can grow within just 24 to 48 hours of the incident.
However, the greatest danger is not the risk of disease but the risk of electrocution or explosion. Never enter a flooded area or light matches until the utility companies have shut off the electric and gas service. If you detect or smell gas, immediately evacuate your home and notify the gas company.
You should also never enter your home if you did not turn off the main power switch before flooding. Touching electrical lines, wires, equipment, and fixtures during and after a flood can be dangerous even with the power switched off.

Why Sewage Flood Cleanup Requires Professional Restoration
Water damage is a progressive issue, so the longer you wait to deal with standing water, the greater the damage to your home. Your carpets, your furniture, your walls, and much more, will be compromised without quick and proper intervention.
Furthermore, sewage flood restoration poses unique challenges and genuine dangers. Professional restoration technicians use the proper equipment and follow standard safety procedures and remediation techniques that typical homeowners would not normally access.

- Remove and replace damaged drywall and floors if necessary
- Use industrial dehumidifiers and air scrubbers to speed up the drying process
