Drafty houses or apartments can be uncomfortable as well as costly. A few simple steps can eliminate some of the problems. Make sure all of the storm windows are closed and lock all of the windows. Locked windows create a better seal and stop a lot of air flow. Check the weather stripping around the exterior doors, if you can see daylight around a closed door it probably needs new weather stripping, don't forget to check the bottom of the door oftentimes this gap goes unnoticed and lets in a lot of unwanted cold air.If you have an older place with older windows you might try putting plastic around your windows. The new style that allows you to use a hairdryer to shrink the plastic are inexpensive as well as simple to install.
