Detailed Breakdown

What Causes Sewage Backups?

Common culprits include:

• Heavy rains or flooding overwhelming municipal systems (EPA: Causes of Sewer Backups).
  
  
• Tree roots infiltrating old pipes.
  
  
• Blocked or broken sewer lines due to grease, debris, or structural failure.
  
  
• Sump pump or backwater valve failures.
  
  

Why Sewage Cleanup Is Not a DIY Job

According to the Centers for Disease Control and Prevention (CDC), sewage is classified as Category 3 “black water”—loaded with dangerous bacteria, viruses, and even parasites. Exposure can lead to serious illness.

Professional teams use:

• Hazmat-grade personal protective equipment (PPE).
  
  
• Specialized extraction and disinfection equipment.
  
  
• Air scrubbers to prevent the spread of airborne contaminants.
  
  

Step-by-Step: What Happens During Professional Cleanup

1. Assessment & Containment: Rapid evaluation and isolation of affected areas.
   
   
2. Extraction: Removal of contaminated water and solids with industrial pumps.
   
   
3. Demolition (if needed): Removal of saturated drywall, flooring, or insulation.
   
   
4. Disinfection: High-powered cleaning agents kill bacteria and viruses.
   
   
5. Drying & Dehumidification: Prevents mold and structural damage.
   
   
6. Restoration: Rebuilding and repairs as needed.
