It can progress to category 2 if not addressed quickly. You can expect an average clean-up cost of around $3.75 per square foot to repair clean water damage.

  • Category 2 (Gray water): This water contains harmful contaminants and comes from appliances, such as washing machines and overflowing dishwashers, or toilet water containing cleaning products and waste. The average cost is about $4.50 per square foot to repair graywater water damage.

  • Category 3 (Black water): This is water that comes from contaminated sources, such as sewer pipes. Due to their extreme contamination, its average cost is relatively expensive, and you can expect it to be around $7 per square foot.
