Eliminate Condensation on Windows

      Water and ice buildup on the inside of windows can cause damage to your house, as well as promote mold growth on the windows structure and frame. Excessive condensation or frost accumulation on windows may be one sign of too much indoor moisture or a cold window. 

      To prevent this condensation, you can warm the window’s surface by covering the window with plastic. You will also want to lower the humidity in the home to under 40 percent in the winter. These two things should greatly reduce condensation in the home. 

       Dehumidifiers generally lower the humidity level to only about 50 percent, so they are not adequate for limiting condensation during the winter. To help lower humidity levels, shut off humidifiers. Install and use outside air exhaust fans when cooking and run fans during baths and showers. These will help reduce unwanted moisture in your home, reducing the risk of mold growth. 

      But, remember that low humidity (below 30 percent) can lead to dry skin and irritate nasal passages, increasing the chance of respiratory illnesses.
