The first sign that you should be watching humidity levels in your home is when there is frequent condensation on windows. Some condensation is normal. If windows are frequently foggy you need to take notice. When moisture levels are high household condensation can be seen on a number of surfaces in your house.  Condensation occurs when water vapor adheres to a window or surface with a cooler temperature. The vapor turns into water droplets on the surface. Other surfaces that the vapor can appear as condensation on is countertops, floors and walls. When it affects porous surfaces such as walls there is a chance it can penetrate the surface and deteriorate the wall and cause health-threatening mold or mildew.
