What is Mildew?
Mildew refers to a type of fungi, typically white, gray, or greenish, that grows on organic materials like wood, drywall, and fabric when exposed to moisture. Unlike mold, it usually stays on surfaces rather than penetrating deeply, but both require prompt action to prevent spread. It flourishes in areas with poor ventilation, high humidity, or water leaks, making basements, bathrooms, and crawl spaces common hotspots.
Common Causes and Signs
Mildew development is driven by excess moisture, inadequate airflow, and organic substrates. Key signs include a musty odor, visible discolored patches, and a sticky or damp texture on affected surfaces. Common locations include shower tiles, window sills, and damp corners where air circulation is limited, emphasizing the need for regular inspection and moisture control.
Health Risks and Prevention
Prolonged exposure to mildew spores can trigger respiratory issues, allergies, and skin irritation, especially in sensitive individuals. Preventing mildew starts with controlling humidity below 60%, fixing leaks promptly, improving ventilation, and cleaning regularly with natural or commercial mold inhibitors. Using dehumidifiers and ensuring proper airflow in enclosed spaces significantly reduces risk.
