My problem is that my door has a wide crack under it. It lets in insects and lets out the air or heat. I know you can use a foam seal but need something to go all around the door. I haven't tried any thing yet because I dont know what to start. Can anyone provide a suggestion for the method I should use?

You need to add a threshold to the door to seal under it. There a number of thresholds where you can then adjust the height to meet the bottom of the door. Around the other 3 sides you need to add weather stripping.
