Why the First Hours After Flooding Matter
Water damages finishes, furniture, and structural elements quickly. Porous materials — drywall, wood, mineral insulation — absorb moisture deep into their layers and often cannot be reused. Soaked particleboard swells and warps beyond repair. Laminate buckles, underlayment saturates, wallpaper separates from the wall. The critical window is the first 24 to 48 hours. If moisture is not removed from the deeper structural layers within that time, the risk of mold and fungal colonization increases sharply.
