How to Stop Drafts From Entering Doors & Windows

During colder months, you may notice more cool drafts coming from your doors and windows. Not only do these drafts reduce the number of places where you can sit comfortably, they raise the cost of heating your home. By taking a few proactive measures, you can keep your home well-sealed and comfortable throughout the winter months.

Things You'll Need

• Towels or blankets
• Bleach-based cleaner
• Window weather stripping
• Door weather stripping
• Window-sealing kit
• Blow dryer

Instructions

1. Use temporary measures. Since you probably don't have the more permanent materials on hand, you can stop drafts temporarily by placing blankets or towels near the crack. Roll them up and place them near the bottom of the door or between the window and screen.

2. Clean the bottom of the window. Use a bleach-based cleaner to move any mold or mildew that may have accumulated. If possible, tilt the moving portion of the window forward and clean both sides as well.

3. Stick on weather stripping. Once the edges of the window are dry, run a line of window weather stripping along the bottom and sides (if possible).

4. Seal your door. Repeat Steps 2 and 3 for your doors, using the door weather stripping.

5. Seal the windows. Window-sealing kits typically include a roll of shrinkwrap-like plastic that you stretch over the window frame and blow dry to tighten. Check the instructions of your specific kit for any extra steps.

6. Consider replacement. Many state and federal agencies offer incentives, grants and even tax credits to offset the cost of replacing less efficient doors and windows with energy-efficient versions. Replacement usually removes the need for annual sealing, and can reduce your heating and cooling bills year-round.

Tips & Warnings

• Stubborn under-the-door drafts can be cured with buckwheat-filled rolls called "draft dodgers." Just put them against the base of the door to block the draft.

• Remove plastic window sealants during the summer to prevent excess heat or melted plastic.
