Thank you for your feedback. The entry door, not the 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. We want to assist you with your concern. Please contact the Andersen Solution Center at 855-337-8822. Kindly have the serial number of your door ready when you call. You will find it anywhere on the hinge part, on a white or silver sticker. - Jay
