If you notice a draft coming inside, Manfredini recommends first checking if your windows are locked. He says the No. 1 mistake people forget to do with their windows is lock them. Without locking them, you’re likely leaving open space, even the smallest sliver, to let in that cool air and make your home feel cold.

What's the secret to sealing that tiny crack? Manfredini suggests using adhesive weather stripping, which should only cost a few bucks. Once the weather stripping is in and the window is locked, cold weather doesn’t stand a chance!

How to do it:

  1. To install adhesive weather stripping, first open the window and remove the old stripping.
  2. Then stick a new strip right over where the old piece was.

  4. If you still notice a draft, place a piece of clay around the window to seal the draft completely.

You’ll be so much warmer and you might even lower your energy bills. Now that's music to our ears!
