Storm door installation will cost $200 to $400. It will take a professional half a day to a full day to install a storm door. The length of time it will take depends on the complexity of the installation. If the installation is straightforward then it will take less time, and therefore, cost less.
The clerk informed her that one door was one inch and change wider than standard size and the other door was one inch and change taller than standard size. In order to install either new door, Home Depot would need to add a small amount of trim around one side of each door frame for the cost of $75 per door. This $75 per-door modification fee is in addition to the $127 per-door installation fee (plus the $15 per-door removal fee, if you have old storm doors still in place) that Home Depot will charge to install the door (after the $35 measurement fee).
