Why is there a draft from my door?
A draft occurs when gaps form around doors and windows, allowing outside air to get in the house. In fall and autumn, this can make the inside of your home cold and force your heater to work harder. In the summer months, the infiltration of warm air might make you crank up the fans or AC in order to stay cool.
How do you winterize an old door?
How to Winterize Your Home’s Doors and Windows
- Check your window panes and storm windows for cracks and replace any that are damaged.
- Install those storm windows (and doors) if they aren’t installed year-round.
- Caulk around your windows (or apply rope caulk), especially anyplace you notice a breeze slipping in.
How do you fill the gap at the top of a door?
Weatherstripping. A small gap above the door can be filled by weatherstripping, which is flexible and will conform to the gap, filling the space up and preventing air from entering and exiting. Different types of weatherstripping are made from rubber, felt and foam.
