Water Damage Restoration Cost Per Square Foot
Quick answer
Water damage restoration runs $3–$7 per square foot for clean water, $4–$8 for gray, and $7–$15 for Category 3, all for mitigation only — extraction, drying and removal. Add reconstruction and the range becomes $10–$25 per square foot, because putting drywall, flooring and trim back is a separate scope from taking them out. Per-square-foot figures are useful for sanity-checking a quote and poor for predicting one, since the square footage counted is the affected area a meter defines, not the room you are standing in. Per-foot figures cannot price your job; a scope can. For one on your own rooms, call (888) 840-6512, answered 24/7.
