The third most populated city in the US, Chicago, Illinois also has one of the most extreme weather patterns. Lying in the humid continental climate zone, summers can be hot and humid while winters are cold. Thunderstorms are also common during the summer and spring.
These weather changes can cause moisture and humidity issues in any home's basement. Basement humidity and moisture foster mold and mildew growth, and this can cause health issues. It can also make your tools and appliances rusty, and it can affect electronic items you may have kept in your basement.
