You can lose a lot of household heat during cold winters through poorly fitted or uninsulated exterior doors. Particularly in older homes, door frames and entire walls may have shifted slightly over the years, leading to gaps and openings between the door and the frame. Rather than rebuilding the entire door frame, you can make up for this problem by installing weather stripping to stop the draft.
Things You'll Need
- Weather stripping
- Tape measure
- Door sweep
- Finish nails
Inspect the corners of the door to find out what the problem is. Close the door tightly and look at the corners from inside to see if you can see any light coming through between the door and the frame.
Open the door and look at the corners of the frame. If weather stripping is already present, it may have been installed improperly, leaving gaps at the corners. If this is the case, remove the old weather stripping and replace it with new strips.
Cut the new weather stripping precisely so that it fits perfectly into the space around the door. Depending on the type of weather stripping you have, you can cut it with scissors, or you may need a hack saw if it has a metal frame around it. You can attach wooden weather stripping with small finish nails, and metal weather stripping with screws. Take special care to fit the horizontal and vertical pieces of weather stripping tightly together at the corners.
Install a rubber or felt sweep on the bottom of the door. This will help the door to be airtight when it is shut, because the flexible sweep will fill up all the space between the bottom of the door and the threshold.
Tighten the screws that hold the hinges to the door and to the frame. When you lift the weight of the door by the doorknob, there shouldn't be any flex in its movement.
