However, these same features can also cause moisture to build up inside the house. You need some moisture to be healthy. If your skin, nose or throat is too dry or you have a high static electricity level causing shocks or clothing clinging to your body, your humidity level is probably too low. Your home also needs some to avoid wood shrinkage, but too much moisture can result in damage to your home.
Too much humidity can cause staining of the ceiling, warping and/or staining of wall panels and can even cause mildew in fabrics or carpeting giving your home a musty odor. This damage may not be immediately obvious as some of it may occur within the walls.
Normal living conditions such as cooking, bathing, washing and even breathing and perspiring create moisture. A family of 4 can introduce 2-3 gallons of water, in the form of moisture, per day into their home's environment.
Other sources of humidity can be moisture from the crawl space under your home, supplementary heat sources that are not properly vented or from humidifiers that are used during the heating season.
The first evidence of too much moisture is condensation on the windows or other cool surfaces inside your home. Damp spots on ceilings or the inside of exterior walls are other signs. Blisters in the outside painted areas or buckling or bulging of the siding can mean that moisture from inside the home has been forced out to the siding due to "vapor pressure."
