There are a few basic things you'll need to install a storm door: weather stripping, a door sweep, screws, and a drill.1. Cut the weather stripping to fit the width of your door frame using scissors. Peel off the adhesive backing and stick it to the frame of your door.2. Affix the door sweep to the bottom of your storm door using screws or nails. Make sure it's sealed against the threshold so that no water can get in.3. Open your storm door and place it in front of your main entry door. Line up the hinges on both doors and mark where they should be drilled into your main entry door frame.

For the average do-it-yourself homeowner, installing a storm door is a relatively easy task. Here are the basic steps:1. Measure the width of your door opening and purchase a storm door that is one inch narrower than your door opening. This will allow for the 1/4 inch gap needed between the edge of the storm door and your exterior door. 2. Remove your old screen door and hinges from the doorway. 3. With the help of another person, hold the storm door in place and mark where to drill holes for screws using a nail or sharp object like a pencil. 4. Drill pilot holes into your marks.
