Aluminum frame storm doors have removable glass inserts for winter and removable screens for spring, summer and fall. If you have an aluminum storm door then you have a removable screen insert and you don't have to remove the door, just remove the screen insert when repairing the screen. For this tutorial, I'll explain how to repair an aluminum screen door where the screen is integral to the door.
Screens can be made either of aluminum or fiberglass and are held in place by friction using a simple flexible gasket called a retainer spline. The plastic retainer spline is installed using, you guessed it, a spline (or screen) installation tool!
So let's take a look on how to replace a screen in an aluminum screen storm door.
NOTE: This same technique can be used on a wooden screen door using retainer spline to fasten the screen to the wood frame. For information on how to repair a wooden screen door that uses staples to fasten the screen instead of retainer spline, see Screen Repair - Wood Frame.
