10 Warning Signs of Mold In Your Home

September 24, 20246 min read

Mold can be a homeowner’s nightmare. Not only can it damage your property, but mold can also pose serious health risks if left untreated. Recognizing mold symptoms early can help you take the necessary steps to protect both your home and your family. Let’s dive into some common warning signs of mold toxicity that may signal it’s time for a closer look.

What is Mold, and Why Is It Harmful?

Mold is a type of fungus that thrives in damp, humid environments. Some types, like black mold (Stachybotrys chartarum), are more dangerous than others and can cause severe health problems. Mold toxicity occurs when mold spores are inhaled, ingested, or come into contact with the skin. Prolonged exposure to mold can lead to serious health issues, especially for those with compromised immune systems or respiratory conditions.

Common Mold Symptoms in Your Home

Here at Advanced Recovery of the Midwest, we see how the heat and humidity of summer causes rapid mold growth in homes with water damage. Even a small leak can cause mold growth over time... and when a hot water pipe breaks mold can begin growing in as little as 24 hours.

To help Kansas City homeowners protect their homes, here are 14 signs that might indicate mold is lurking in your home:

  1. Musty or Damp Odors
    A persistent musty smell is often one of the first signs homeowners notice of mold in the house. Mold releases chemicals that can create a stale odor, even if the mold itself isn’t visible. If you have an unexplained odor in your home, ask for a free inspection or consider investing in a mold test for your home.

  2. Visible Black, Green, or White Spots
    Mold can appear in a variety of colors, including black, green, or white. You might notice these spots on walls, ceilings, or floors, especially in areas prone to moisture like bathrooms, kitchens, or basements.

    If you see mold spots, it's important NOT to wipe or scrub without proper protective gear. Agitating the mold can cause spores to release into the air, spreading the problem and making it worse.

    Many homeowners attempt to clean mold themselves with bleach or other household cleaners. Bleach can remove visible mold spots, but the mold's roots will continue to grow beneath the surface. After a few days, the mold will likely grow back worse than before.

    Other signs include:

  3. Water Damage or Discoloration
    Water stains or discoloration on walls, ceilings, or floors are often a sign that there’s a moisture problem—perfect conditions for mold to grow.

  4. Warping or Peeling Paint
    Mold often grows behind walls, causing the paint or wallpaper to bubble, crack, or peel. This is particularly common in bathrooms or near windows where condensation builds up.

  5. Increased Humidity or Condensation
    Excess humidity in your home can create a breeding ground for mold. You might notice condensation on windows, pipes, or walls, which can lead to dangerous black mold growth if left unchecked.

  6. Frequent Allergy-Like Symptoms
    Mold exposure can trigger mold allergy symptoms similar to seasonal allergies, including sneezing, runny nose, itchy eyes, and coughing. If these symptoms persist year-round, it might be a sign of mold in your house.

  7. Respiratory Issues
    Mold spores can irritate the lungs, leading to symptoms like wheezing, difficulty breathing, or tightness in the chest. For individuals with asthma or chronic respiratory issues, mold exposure can cause more frequent flare-ups.

    If you're having unexplained flare-ups or respiratory issues, consider investing in a mold test.

  8. Persistent Headaches or Fatigue
    Prolonged exposure to mold can lead to mold toxicity, which manifests as persistent headaches, brain fog, or fatigue. If you feel unusually tired or foggy in your home, mold might be the culprit.

  9. Unexplained Rashes or Skin Irritation
    Some people experience allergic skin reactions from mold, such as red, itchy patches or unexplained rashes. Skin exposure to mold spores can aggravate these symptoms.

  10. Mold Growth on Furniture or Fabrics
    Mold doesn’t just grow on walls—it can also spread to soft surfaces like furniture, curtains, and carpets. You might notice dark spots or mildew smells on fabrics, indicating a mold problem.

  11. Condensation or Leaks Around Pipes and Windows
    Mold loves moist environments. If you have leaks around windows or plumbing, it can lead to black mold in hard-to-see areas like behind walls or under sinks.

  12. Asthma Flare-Ups
    People with asthma are particularly sensitive to mold exposure symptoms. If asthma attacks become more frequent or severe when you’re at home, it’s possible that mold is contributing to the problem.

  13. Peeling or Bubbling Drywall
    Just like with paint, mold growth behind drywall can cause it to peel or bubble. This is a telltale sign of water damage and mold.

  14. Unexplained Musty Odor in HVAC Systems
    Mold can grow inside heating and cooling systems, releasing spores into the air whenever the system is running. If you notice a musty smell when your HVAC system is on, mold could be lurking inside the ducts.

Health Risks of Mold Exposure

Exposure to mold can cause various health issues, ranging from mild allergic reactions to more serious conditions. Common mold exposure symptoms include:

  • Coughing

  • Sneezing

  • Itchy or watery eyes

  • Skin rashes

  • Fatigue

  • Headaches

In more severe cases, especially with long-term exposure to black mold, you might experience neurological symptoms, chronic respiratory issues, or immune system problems. It’s important to recognize these symptoms and take action to protect your health.

How to Prevent Mold Growth

To reduce the risk of mold growing in your home, follow these tips:

  1. Control Humidity: Keep humidity levels below 50% with a dehumidifier, especially in basements and bathrooms.

  2. Fix Leaks Immediately: Address any leaks in your roof, walls, or plumbing to prevent moisture from accumulating.

  3. Ventilate Properly: Use fans or open windows to increase ventilation, particularly in bathrooms, kitchens, and laundry rooms.

  4. Clean Regularly: Keep your home clean and dry to prevent mold from finding a place to grow. Pay attention to areas where mold is likely to develop, like under sinks, in shower corners, or behind appliances.

When to Call a Professional

If you notice any of these mold symptoms or are concerned about potential mold in your house, it’s crucial to address the issue quickly. While small mold problems can often be handled with easy solutions, large-scale mold infestations—especially involving black mold—require professional remediation to ensure the mold is completely removed and your home is safe.

Conclusion

Mold growth in your home is not only damaging to your property but can also pose significant health risks. Knowing the signs of mold and addressing the problem early can help you avoid the dangers of mold toxicity and keep your home healthy and mold-free.
