• Increased Allergic Reactions. If you or your family members are experiencing a sudden increase in allergy-like symptoms—sneezing, coughing, asthma flare-ups, watery eyes, or skin irritation—it could be a sign of hidden mold. While there may be other culprits, mold spores can trigger allergic reactions, especially in sensitive individuals. A mold test can help determine if mold is the underlying cause.
• Persistent Water Leaks. Previous water damage or ongoing moisture issues create perfect conditions for hidden mold growth. Even if you can’t see the mold yet, these conditions may warrant a professional mold test, especially in areas like crawl spaces or behind walls where growth might not be visible.
• Weird Smells. Mold has a distinct odor that often serves as one of the first warning signs of its presence. If you notice a persistent musty smell but can’t locate visible mold, professional testing can help pinpoint hidden growth. Trust your nose—the stronger the odor, the more likely you are to have a mold issue.
• Peeling Paint or Wallpaper. Bubbling paint or loose wallpaper often indicates moisture problems behind your walls. And where there’s moisture, there’ll likely be mold. These conditions typically require investigation and possibly a mold test to assess the situation appropriately.
