The rotting or deterioration of a wood core storm door with reference to the time is dependent on some factors. It may depend on how the door was installed, the environment or the location where the door is installed and how the door is being maintained. These factors contribute to the deterioration of the door.
Modesty aside, we also have customers who have wood core doors installed in their homes for more than ten years, and yet their doors are still intact and not showing any sign of deterioration except for the wear and tear issue of some replaceable parts. We are deeply sorry about what happened with your storm door. Please allow us to assist you with this. Kindly call us at 1-855-337-8822 when you are near your door and we will be happy to help. Kindly have the serial number of the storm door ready. You will find it anywhere on the hinge part, on a white or silver sticker. - Charmaine
