The longevity of sewage contamination depends on several factors, such as the extent of the sewage backup, the types of materials affected, and the immediacy and effectiveness of the cleanup process. Left untreated, sewage contamination can pose serious health risks and may lead to long-term property damage. The hazardous substances present in sewage, including bacteria, viruses, and fungi, can survive for weeks or even months in a moist, untreated environment. However, with professional intervention and thorough cleaning and disinfection procedures, these contaminants can be effectively eliminated. At iDry Columbus, we utilize advanced cleaning techniques and professional-grade disinfectants to ensure a thorough cleanup. Once we've completed our cleaning and restoration process, you can be assured that the contamination has been entirely removed. However, it's essential to address sewage backups promptly to minimize damage and potential health risks.
