If you can close a weather stripping in your door and then pull it out easily or if your door rattles from noise or the wind, it means it’s just not seated snuggly. The easiest starting place to for this fix is to add weather stripping. Usually, doors made over the past 25 years have had weather stripping built onto them. But being a door is rough work. Over time, the weather stripping gets stripped from the door. In some cases, the same weather stripping types are still used by the door manufacturer and can be easily replaced. Usually with much older homes, it’s not the case. You’ll be either replacing worn-out weather stripping someone else applied, or you’ll be putting on brand new.
First, measure the gap between the door surface and the door jamb at several places. Add about 1/16 of an inch to this measurement and this will give you a rough thickness of the self-adhesive foam or felt you will need to apply. Typically, I apply the foam stripping to the door jamb. Since the door jamb doesn’t go anywhere there’s less of a chance for something bumping against it and tearing off the foam. The door, on the other hand, is meant to move and will encounter all sort of things in its travels. As mentioned, you want the door to close firmly. Be sure to buy more foam than you will need so you can add and adjust the foam until you have a good seal.
