Mildew typically appears as patchy, powdery growths in shades of black, gray, or greenish-black.

Unlike fresh paint or plaster, mildew presents a distinct texture—often powdery, slimy, or velvety to the touch. It clings to walls with a damp, musty feel, and may exude a strong, unpleasant odor. These sensory cues help differentiate mildew from typical wall wear, even before visible discoloration appears, making early detection easier.
Mildew thrives in warm, humid, and poorly ventilated spaces. Look for mildew on internal walls in bathrooms, near leaky pipes, around windows with condensation, or in areas with slow air circulation. Persistent moisture from plumbing leaks, high humidity, or inadequate drying after cleaning creates ideal conditions for mildew to flourish, making these zones critical to inspect regularly.
Recognizing mildew on walls early is key to preventing costly damage and health risks. By identifying its unique colors, textures, and common growth spots, homeowners can take swift action to clean and dry affected areas.
