We apologize for the inconvenience that you have experienced with the door. The intended purpose or function of a storm door is to reduce the exposure of an entry door to the elements. A storm door aids in reducing the amount of air or moisture coming through in order to enhance the function of your entry door system. Your entry door, not storm door, is considered the main line of defense in protecting your home from the outside elements. While installing a storm door helps to reduce the amount of air or water that reaches your entry door, it is important to keep in mind that your storm door is intended to reduce the amount of exposure your entry door has to the outside elements and may not prevent all water or air from reaching your entry door. Water penetration may occur as the result of factors which may or may not be related to your storm door unit, such as the location of the storm door on your home or weather conditions. Should you need assistance with your door, please contact the Andersen Solution Center at 855-337-8822 - Arnie
