Remove unsalvageable or wet materials
IICRC states that the following methods to identifying moisture sources will be the most effective in water damage cleanup.
1. When the water source can be identified as wind-blown, it is important to begin the circulation of air before microbial growth can occur.
- Begin at the source of water entry and trace the path of wetting. Removal ceiling panels, wall materials, and insulation as you go along.
- Remove carpeting, padding, tackboard, and any other subflooring materials.
- Remove solid or laminated wood flooring and sheet vinyl.
2. When the water source can be identified from rising water, starting air circulation is also extremely important.
- Remove drywall, paneling or other wall materials. It is important to remove materials 15-24" inches above the visible water line.
- Remove all wet insulation materials in the area of the drywall removal. Leave only wall framing components that are intact and have minimal porosity. These components have a better chance of being cleaned and decontaminated.
- Remove all floor coverings. Carpet, cushion, padding, sheet vinyl, felt, laminate, and tile flooring materials should all be removed. Hardwood flooring should be removed since contaminants can be trapped underneath and cause rapid microorganism growth. Microorganism growth is typically associated with a strong odor and health hazards.
