As a responsible homeowner, you will want to be aware of the signs that indicate your home needs new windows. This way, when that time comes, you will realize it and be able to take immediate action.  You Can Feel the Draft Even if you like the feel of cool air, it should never come through the windows of your home while they are closed. If you are feeling a draft, it could be because there is a broken seam or the windows are simply too old to be truly energy efficient.
