Weatherstripping Doors

By Barry Solomon , last updated December 21, 2011

If the winter winds are making their way past your door, then it is time to weatherstrip your doors. Cold air entering your home can make you uncomfortable and it can also add to your heating bills. Your energy bills also go up if the cool air produced by your air conditioner during the summer months is rapidly exiting to your front yard. Here you will learn how to weatherstrip your doors.

Examining the Door Frame

Begin by examining the door frame and removing all the old weatherstripping that is no longer performing. If you live in a newer home, your door frame will likely have a slot for weatherstripping. Older homes will simply have it attached to the door frame. Buy your new weatherstripping at a home improvement store.

Installing Weatherstripping

Now you can install weatherstripping to the bottom of the door. It comes with adjustable height of up to a quarter of an inch. And in a newer home you will also have an adjustable threshold. Turning the Philips head screws will raise or lower your threshold to compress the weatherstripping.

Frame Installation

Next is the door frame installation. Measure the gap between the door and the frame and then purchase weatherstripping that is a little bit thicker. Use high compression foam, as this will fill gaps better. On the top frame and the frame that has the door striker, the weatherstripping should be installed on the side facing you when you are standing inside your house. On the side of the door frame that has the door hinges, the weatherstripping should be installed on the side that faces you when you stand inside the frame. Again, if you have a new home this is simplified by the fact that you have grooves around the frame for weatherstripping and you only need to attach it there.

Once the weatherstripping is completely installed, you can make a final adjustment, if necessary, by adjusting the striker plate to get full compression.
