How to Prevent Door Drafts

A drafty door can be one of the biggest causes of increased energy bills in your home. That’s why it pays to be proactive when spotting gaps. Diagnosing a drafty door isn’t difficult, and there are plenty of ways to patch them up with a small amount of time and effort.

Learn how to seal a drafty door and how to spot one before it becomes a problem.

What Causes Door Drafts?

Door drafts are usually caused by wear and tear. Since you use your front door every day, the likelihood of the door sweep or weather stripping getting worn is high. Because of this, it’s always a good idea to pay close attention to the condition of your door.

Diagnose the Problem

If your house feels cooler and your energy bills keep increasing, the first step of any solution is to check for gaps. Windows, attics, and doors are all common culprits, and each should be checked carefully. Simply hold your hand up to the area of the suspected gap to see if you can feel any change in temperature.

You can also test the draftiness of your door using a fan or a hair dryer. Simply use one of these tools to create a breeze on one side of the door. Then, have a partner stand on the opposite side to feel for any drafts. If you can feel air coming through your door, it’s time to seek a solution.

Check Your Door’s Alignment

If you suspect your door may be drafty, there’s one simple way you can tell for sure. Misaligned doors are easy to spot, as they tend to stop or stick when opened or can be visibly crooked. You can also check to see if yours has any loose screws or warped wood.

How to Fix a Drafty Front Door

Once you’ve determined whether you have a drafty door, it’s time to fix it. There are plenty of ways to help improve your door’s energy efficiency.


Weatherstripping is inexpensive and easy to apply. However, it must cover the entire perimeter of your door, even the corners. Also, it’s crucial that it stays in good condition. Replace it every two to three years for best results.

Door Sweeps

Most doors come with sweeps already installed. They are the thin strips of material along the bottom of your door. When working properly, they create an airtight seal that insulates the door at this vulnerable point. Usually, after a few years, they get cracked or worn and need replacing.

There are various types of door sweep available, but the most popular consist of a metal strip with a rubber or brush-like sweep on the bottom. These are measured to size, cut, and screwed into the bottom of your door.

Consider a Replacement Door

Sometimes, the only way to fix a draft in your front door is to replace the door entirely. While it may demand more upfront cost than the other two methods, in the long run, a quality door will drastically cut down on heating and cooling bills. However, to make sure the job is done right, it’s important to find the right person to handle the installation.
