Air Coming in Through Door


Do you often feel a draft or notice air coming in through your door? This can be quite uncomfortable, especially during extreme weather conditions. In this article, we will explore the possible reasons behind this issue and provide you with some effective solutions to prevent air infiltration through your door.


One of the common reasons for air coming in through the door is worn-out or inadequate weatherstripping. Over time, the weatherstripping can deteriorate, causing gaps between the door and the frame. To address this issue, it is recommended to inspect and replace the weatherstripping if necessary. There are various types of weatherstripping available in the market, such as adhesive-backed foam tapes, V-strip, door sweeps, and more.

Door Threshold

The door threshold, which is located at the bottom of the door, can also be a potential entry point for air. If the threshold is damaged or not properly sealed, air can easily pass through. To fix this issue, you can replace the threshold or use a door sweep, which is a flexible strip attached to the bottom of the door to block the gap and prevent air infiltration.

Door Gaps and Cracks

Inspect your door for any visible gaps or cracks. These gaps can allow air to seep in, making it less energy-efficient. Depending on the severity of the gaps, you can either repair them by using caulk or sealant or consider replacing the door if it is beyond repair.

Proper Insulation

Inadequate insulation around the door frame can also contribute to air leakage. Ensure that the area around the door frame is properly insulated to prevent air infiltration. You can use expanding foam insulation or install foam gaskets to seal any gaps between the door frame and the wall.

Door Alignment

If your door is not properly aligned, it may not close tightly, leaving gaps for air to come through. Check the hinges and screws to ensure they are tight and properly aligned. If necessary, adjust the hinges or call a professional to realign the door for a better seal.

Double-Pane or Storm Doors

If you live in an area with extreme weather conditions, consider installing double-pane or storm doors. These doors provide an extra layer of insulation and help to reduce air infiltration. They are designed to withstand harsh weather and can significantly improve energy efficiency.

Regular Maintenance

Regularly inspect and maintain your doors to prevent any potential issues that may lead to air infiltration. Clean the door frames, hinges, and weatherstripping regularly to remove dirt and debris that can affect their performance. Lubricate the hinges and moving parts to ensure smooth operation.

Professional Assistance

If you have tried various solutions and still experience air coming in through your door, it is advisable to seek professional assistance. A qualified technician can assess the situation, identify any underlying issues, and provide suitable recommendations to resolve the problem effectively.


Dealing with air coming in through the door can be frustrating, but with the right solutions, you can significantly improve the energy efficiency and comfort of your home. By addressing issues such as weatherstripping, door thresholds, gaps, insulation, alignment, and regular maintenance, you can minimize air infiltration and create a more comfortable living environment.
