Water Damage
Drywall water damage occurs when water saturates drywall, causing it to soften, swell, warp, stain, crack, or crumble, leading to structural weakening, peeling paint/wallpaper, and creating ideal conditions for hazardous mold growth, often signaled by musty odors and visible discoloration. This damage compromises the wall's integrity and necessitates prompt repair to prevent deeper issues with framing, insulation, and hidden mold, requiring professional assessment for severe cases.
Common Signs of Drywall Water Damage:
- Stains & Discoloration: Yellowish, brown, or dark spots and rings appear as water soaks in.
- Softness & Sponginess: The wall feels mushy or weak to the touch instead of firm.
- Peeling Paint/Wallpaper: Moisture weakens the bond, causing paint to bubble, flake, or wallpaper to lift.
- Cracking & Crumbling: The drywall loses its strength and can develop cracks or break apart.
- Warping & Sagging: The material swells and distorts, potentially sagging or bulging.
- Musty Odors: A persistent damp, moldy smell indicates trapped moisture and mold growth.
- Visible Mold: Green, black, or white fuzzy patches of mold growing on the surface or behind the wall.
Why It's a Problem:
- Structural Failure: Water breaks down the gypsum and paper, destroying the drywall's strength.
- Health Hazards: It creates a perfect breeding ground for mold and mildew, releasing spores that can affect health.
- Hidden Damage: Moisture can travel, damaging insulation, wood framing, and spreading unseen within walls.
What to Do:
- Fix the Source: Stop the water leak first (e.g., leaky pipe, roof).
- Dry Thoroughly: Use dehumidifiers and fans to dry the area completely.
- Assess Damage: Check for softness, mold, and moisture inside the wall.
- Replace Damaged Parts: Severely damaged, soft, or moldy drywall, along with wet insulation, must be removed and replaced.
