What is condensation and why is it happening in my basement or crawl space?
Whenever outside air is warmer than inside air, a condensation problem is likely to appear in your basement or crawl space. Basements and crawl spaces are below ground and are therefore fairly cool most of the time. When moist, hot air (like that found on a summer day) is combined with a cool basement or crawl space climate, condensation forms on cool surfaces such as ductwork, glass and concrete foundations.
