Health Risks of Mold Exposure in Drywall Homes

Mold is a type of fungus that can grow on drywall when moisture levels are high. Exposure to mold can trigger health problems such as allergies, asthma, and other respiratory issues.

At What Moisture Level Does Mold Grow in Drywall?

Mold spores are always present in the air, but they need a moist environment to grow. Mold can start growing on drywall when the moisture content reaches 30% or more. This can occur due to leaks, condensation, or even high humidity levels.

Health Risks of Mold Exposure

Respiratory problems: Mold spores can irritate the lungs and cause respiratory symptoms such as coughing, wheezing, and shortness of breath.
Allergies: Mold can trigger allergic reactions, resulting in symptoms like runny nose, sneezing, and itchy eyes.
Asthma attacks: People with asthma may experience more frequent and severe asthma attacks when exposed to mold.
Other health effects: Mold exposure has also been linked to fatigue, headaches, nausea, and skin irritation.

Preventing Mold Growth in Drywall

Control moisture levels: Use a dehumidifier to reduce humidity levels and prevent moisture from accumulating on drywall.
Repair leaks promptly: Any leaks in plumbing or roofing should be fixed immediately to prevent water from seeping into drywall.
Improve ventilation: Ensure there is adequate ventilation in areas where drywall is installed, allowing air to circulate and prevent moisture buildup.
Use mold-resistant drywall: Consider using mold-resistant drywall in areas prone to high moisture, such as bathrooms and basements.

If You Suspect Mold Growth

If you suspect mold growth in your drywall, it is crucial to address the issue promptly. Mold can spread quickly and pose health risks. Consider the following steps:

Contact a professional: Hiring a qualified mold remediation specialist is recommended to safely remove mold and identify the underlying cause of its growth.
Wear protective gear: When cleaning or handling mold, wear gloves, a mask, and protective clothing to avoid exposure.
Ventilate the area: Open windows and doors to provide ventilation during and after cleaning to reduce mold spore concentrations.
