Depending on the age of your home, you may have some drafty doors. Our home is 12 years old. We have a basement door near our kitchen. Below the basement door is about a 3/4 inch gap. This gap allows air from the basement into our main level and allows our main level air into the basement. This means that our toasty, heater air (in the winter), and our cool, air conditioner air (in the summer) seeps into our unfinished basement.
Prevent the escape of air into your basement, garage, and exterior of your home by placing a barrier at the bottom of these drafty doors. You can buy something specially made for these doors, or you can use no money at all. If you prefer the "no money" method, grab a bath towel, roll it up into a long roll, and place at the bottom opening of the door. You can also use a bath mat, old t-shirt, or anything that can can be molded to fit the shape of your door.
