Common Symptoms of Mold Exposure & What to Look For

Mold can grow silently in homes and buildings, often going unnoticed until it starts affecting the health of those living or working inside. While mold can cause structural damage, it is the health effects that often prompt people to seek professional mold inspections. Recognizing the symptoms of mold exposure is crucial to addressing the issue early and protecting both your health and your property.

1. Respiratory Issues

The most common health symptoms associated with mold exposure are respiratory problems. Mold spores can irritate the lungs and airways, causing:

• Coughing

• Wheezing

• Shortness of breath

• Chest tightness

People with asthma or pre-existing respiratory conditions may experience more severe reactions, including asthma attacks.

2. Allergic Reactions

Mold acts as an allergen for many people, even those without known allergies. Common symptoms include:

• Sneezing

• Runny or stuffy nose

• Itchy or watery eyes

• Throat irritation

• Skin rashes

These symptoms can be mistaken for seasonal allergies or a cold, but if they persist or worsen when indoors, mold could be the culprit.

3. Headaches and Fatigue

Prolonged mold exposure can lead to more subtle symptoms such as chronic headaches or unexplained fatigue. The body’s immune system may become overworked trying to fight off the irritants caused by mold spores, leading to constant tiredness or fogginess.

4. Sinus and Ear Infections

Repeated sinus infections, congestion, or ear infections without a clear cause could be linked to mold exposure. Mold spores can irritate the sinuses and nasal passages, increasing the risk of infection or inflammation.

5. Skin Irritation

Direct contact with mold or prolonged exposure to mold spores in the air can cause skin reactions such as:

• Rashes

• Itching

• Hives

In some cases, mold exposure can exacerbate conditions like eczema, leading to flare-ups.

6. Compromised Immune System Responses

Individuals with weakened immune systems, such as the elderly or those undergoing medical treatments, are particularly susceptible to mold-related health issues. Long-term exposure to mold can lead to more severe health complications, including lung infections and chronic respiratory diseases.

When to Seek a Mold Inspection

If you or your family members experience any of these symptoms—especially if they persist or worsen indoors—it’s crucial to get a professional mold inspection. Mold spores can affect indoor air quality and may be lurking in hidden areas like behind walls, under floors, or in basements. Early detection and removal are key to preventing long-term health problems and ensuring your home is safe.
