Can I clean up sewage myself?
Strongly recommend you don't. Black water carries E. coli, hepatitis A, salmonella, parasites, and other pathogens. Without respirator-grade PPE and proper containment, you risk illness and you spread the contamination to areas you don't realize you've touched. Call us, then leave the area until we arrive.
What gets thrown out?
Anything porous that the sewage touched: carpet, pad, drywall up to two feet above the contamination line, fiberglass insulation, particleboard, paper-faced ceiling tiles, fabric upholstery and mattresses. Hard non-porous materials (tile, metal, sealed concrete, finished wood) can be cleaned and sanitized in place. Some semi-porous items (dimensional lumber, hardwood floors) can be saved with proper drying and antimicrobial treatment.
