Visible Mold And Discolored Patches
Most people only realize they have a problem with mold growth in their walls when they see it. In general, mold or mildew inside walls usually stays within the walls.
However, when it does migrate to the wallpaper, drywall, paint, or baseboards, it looks like patchy clusters of small spots. They may be black, gray-green, white, or gray-brown.
Discolored and dark patches, spots, visible mold, and mildew will immediately make it obvious you have a watery problem. These patches are typically cold and moist to the touch. The mold found in your home can profoundly affect your health.
So if you spot it, don’t just paint over it. It’s best to fix the situation before the problem becomes worse.
