WINDOW CONDENSATION The Learning Center More water vapor in the air means a higher indoor humidity.  Higher indoor humidity means more condensation. There are many things that generate indoor moisture, such as humidifiers, heating systems and even plants.  Cooking three meals a day adds four to five pints of water to the air.  Each shower contributes half a pint.  In fact, every activity that uses water (like dishwashing, mopping floors, doing laundry) adds some moisture to the air. Excessive moisture can also come from faulty appliances or equipment, such as unvented heaters or clothes dryers, blocked chimneys, insufficient combustion air for furnaces or water heaters, improperly adjusted humidifiers, plumbing leaks, or inadequate or improperly installed kitchen or bathroom vent fans. Moisture infiltration, through ground water seepage, poor foundation drainage, or leaks in roofs or walls can also be major moisture contributors. Air leaking through the top of the house may also be drawing moisture up from the basement.               13.
