Mold is a tenacious and dangerous fungus that can start growing in the most inconspicuous areas of your home, such as in dark, damp corners, beneath floorboards, and within organic materials. However, its growth can only go unnoticed for a brief period of time, as it releases allergens, irritants, toxins, and other compounds into the air, altering the feel and smell of the indoor environment. To keep your home safe and healthy, it is essential to be aware of the warning signs of mold.
A musty, stale odor – If there is a strange smell in your home, with no apparent cause such as dirty laundry or food waste, then it is likely mold growth. As mold grows, it releases microbial volatile organic compounds (mVOCs) into the air, which produce a distinct unpleasant smell, typically described as damp, earthy, musty, or stale. Act quickly before it spreads further, causes more damage, and becomes a health hazard.
Dark stains on walls or ceilings – Dark-colored patches or stains on walls and ceilings are a warning sign of mold. Mold colonies appear as stains or discolorations on surfaces, and though they can take different shades and colors, they are most commonly black or brown. To verify that they are mold, inspect the texture of the stains, if they are soft, fuzzy, or slimy and can easily be smeared, then it is definitely mold.
Worsening of asthma and allergies – If you or other occupants are experiencing a sudden increase in asthma or allergy symptoms, it is likely that mold is taking over your home. As mold grows, it produces spores and microbial volatile organic compounds (mVOCs) which act as airborne irritants and worsen asthma and allergy symptoms. If symptoms such as sneezing, nasal congestion, coughing, wheezing, shortness of breath, chest tightness, red, watery eyes, and itchy eyes, nose, or throat are on the rise, it could be a warning sign of mold in your home.
Chronic fatigue and headaches – If you experience chronic fatigue and headaches, it could be a warning sign of mold in your home. As mold grows, it produces mycotoxins, and a buildup of these toxins in enclosed spaces with poor air quality triggers a condition called sick building syndrome (SBS). Symptoms of SBS include a blocked or runny nose, dry throat, dry or itchy skin, dizziness, and headaches.
It is crucial to keep an eye out for these warning signs of mold in your home and take immediate action if any are present. A thorough inspection, including in hidden areas, should be carried out to ensure that mold is not growing in your home. Additionally, maintaining good indoor air quality and proper ventilation can help to prevent mold from growing in the first place. If you suspect that mold may be present in your home, it is essential to consult a professional for proper mold removal and remediation.
