The treatment and restoration process depends entirely on the type of water involved.

• Category 1: "Clean Water"Source: This is water from a clean source, like a burst supply line, overflowing sink, or a failed water heater.The Risk: While it starts clean, it's not harmless. After 24-48 hours, this water can mix with building materials and begin to grow bacteria and mold, degrading into Category 2.Our Response: Leading Remediation Tennessee responds quickly to extract the water and begin structural drying to prevent it from becoming a bigger problem.
• Category 2: "Gray Water"Source: This water is contaminated and could cause illness if ingested. Sources include overflowing dishwashers, washing machines, or toilets (with no solid waste).The Risk: This water contains detergents, cleaning agents, or biological contaminants. It requires specialized cleaning and sanitization.Our Response: We remove the water, clean all affected surfaces with antimicrobial treatments, and ensure the property is sanitized before drying.
• Category 3: "Black Water"Source: This is grossly unsanitary water. Sources include sewage backups, rising floodwaters (from rivers or streams), or toilet overflows (with solid waste).The Risk: Black water is highly toxic and contains dangerous pathogens, bacteria, and viruses.
