Did you know a one-eighth
inch gap around an exterior door is equivalent to a six inch square hole in the
side of your house and causes a lot of energy loss? When put in those
terms I realized I would not leave a gaping hole in the side of my house all winter so
I'd better check for air leaks.
There are two ways to check your exterior
doors:
Have
someone stand on the other side of the door and shine a flashlight around the
door's perimeter. If you can see light through the cracks, your door needs
sealing.
OR
Hold a
piece of paper between the door and the frame and shut the door. If you can
pull the paper out without tearing it, you should weather strip around the door.
