What Is a Door Draft Stopper?

Common types are a stuffed fabric tube, vinyl weather stripping, and an aluminum door bottom seal with a nylon brush.

Why Use Door Draft Stoppers?

Door draft stoppers work on a very simple principle: warm air rises and cold air sinks. The cold air wafts under doors, no matter how small the space between the door and the floor is. Here are some benefits of using a door draft guard to solve the problem.

Simple and easy to install

Door snakes and many other door draft stopper ideas are quite straightforward to use. In the case of the door snake, all you have to do is place it at the base of the door.

Some door bottom seals with weatherstripping are designed to be screwed on to the door. There are self-adhesive variations, as well, that make installation easier for you.


Door draft guards are a practical option for keeping your home comfortably warm in colder months. They work just as effectively in warmer months, too, by keeping the cooler air inside the house.

Renters will appreciate that many door draft guards do not require making permanent changes to the home. They won’t put you at risk of violating your rent agreement

 How to Make a Draft Stopper

To make your own, door draft stopper, you’ll need fabric, filling, scissors, and measuring tape. You’ll also need a sewing machine or a needle and thread.

Filling options include:

  • Buckwheat
  • Crushed walnut shells
  • Beans
  • Uncooked rice
  • Beads
  • Insulating polyester or foam (with any of the above added for weight)

Pool noodles do a good job, too, as shown in this video of how to make a twin draft guard.

  1. Measure the width of the door.
  2. Cut a piece of fabric that is 8.5 inches wide and as long as the width of the door plus 1 inch.
  3. Iron the fabric, if needed, so that it is flat. Fold the fabric in half so that the two long sides come together. Ensure that the eventual inside is on the outside. Image by Mystic Art Design from Pixabay
  1. Stitch the two long sides together. You now have a long tube with its short ends open.
  2. Stitch one short end closed, as well. You now have a long tube with one short end open and the other closed.
  3. Turn out the tube so that it is no longer inside-out.
  4. Add the filling through the open end.
  5. Stitch your new door snake closed.
  6. Place it wherever it is needed.

An easier and quicker method is using one leg from a pair of tights. Tie one end closed then cut the tube so that you have the required length plus room to tie the other end once it’s filled.
