During summer, some homeowners would hate going down to their basements due the damp and musty air. This dampness is often caused by water condensation against cool surfaces, which your basement walls usually are. During hot summer days, the cooler temperature in your basement attract more vapor, since the air outside, or above ground is too warm. The simple thing that you need to remember is that the cooler that temperature of your basement is, the worse condensation will be. This problem is also more likely to occur after summer rains, wherein the water in the ground could likewise enter your walls in the form of vapor.
