How Dangerous Is Sewage Backup in a House?

Sewage water soaks into drywall, wood, and flooring. The moisture can weaken structural supports and cause rot. Porous materials like carpets and insulation absorb the waste and become impossible to fully clean.

Even after the water dries, the contamination remains. Sewage leaves behind harmful bacteria and odors. You may need to remove and replace affected materials. The longer the sewage sits, the deeper the damage spreads.

• Drywall may need to be cut out and replaced
• Wooden floor joists can warp and decay
• Carpet and padding usually must be thrown away
• Insulation in walls loses its effectiveness
• Electrical outlets and wiring may be compromised

Cleaning up sewage is not a do-it-yourself job. You need protective gear, industrial disinfectants, and proper disposal methods. The pros use specialized equipment to extract contaminated water and clean surfaces thoroughly.

The cleanup typically involves removing damaged materials, disinfecting the area, and drying it completely. They may also use air scrubbers to filter out particles. In some cases, they will need to access hidden spaces like wall cavities. The exact steps depend on the extent of the backup.

• Wear rubber gloves, boots, and a mask
• Open windows to improve ventilation
• Remove all soaked items from the area
• Disinfect every hard surface with a bleach solution
• Use fans and dehumidifiers to dry the space
• Do not mix cleaning chemicals
