Both finished and unfinished basements tend to be damp and hence prone to mold growth. Molds in basement are predominantly influenced by chronic moisture problems, such as window well leakage. Whether a basement is occupied or not, growth of molds in basement is a health hazard since the spores tend to move upwards to the living spaces. It has been established that basements could be the predominant sources for mold spores in both summer and winter. When people who are susceptible to mold inhale the airborne spores they react to the proteins in the wall of the spores.
How do you know you have molds in basement?
You know you have molds in basement when you smell the “musty” odor or see small black, bluish or white spots along the basement walls. The mold spots may be fuzzy or look raised. Mold growth will occur on any organic or porous materials including paint, cardboard, newspapers, wood, textiles, and carpet that are exposed to moisture. You may also find molds in basement growing on dirt or dust trapped on fiberglass insulation. Mold growth may also be visible on wooden studs and rafters.
How to control molds in basement
Elimination of moisture is the most effective method of mold growth control. To eliminate moisture problems in the basement may involve foundation damp-proofing, fixing grading problems, providing adequate on-lot drainage systems, and sealing areas of moisture ingress. Also remove excessive internal moisture sources in the basement (humidifiers, cooking) and ventilate other sources (clothes dryer, bathroom). If condensation in the summer is the problem, it’s recommended that you do not ventilate the basement directly with warm, humid air. Ventilation through an air conditioning system or with a desiccant-type heat exchanger is recommended.
