How to Fix a Drafty Door Frame

Fixing a drafty door frame is not only beneficial in terms of comfort and energy efficiency, but it also increases the overall security of your home. By sealing the windows and keeping air from entering your house, you can reduce the risk of unwanted entry into your property.

As a bonus, this will also help to muffle outside noises, giving you more peace inside your home. You can find step-by-step instructions on how to fix a drafty door frame in this blog article.

Materials You Will Need

  • A screwdriver
  • Weatherstripping
  • Caulk
  • Putty knife
  • Hammer
  • Nails or screws (depending on the type of weatherstripping)
  • Utility knife
  • Masking tape
  • Sandpaper or sanding block
  • Paint (if desired)

Step-by-step Instructions for How to Fix a Drafty Door Frame

Step 1: Inspect the Door Frame

Check for any drafts around the door frame, which will help you narrow down potential solutions. Pay attention to areas like the threshold and weatherstripping that could be causing air leaks.

Step 2: Check Door Alignment

If one side of the door is higher than the other, it can create a gap between the door and the frame, leading to a draft. Use a level to check for proper alignment. If the door isn’t aligned properly, you can adjust the hinges of the door. Loosen them with the screwdriver and reposition them until you have achieved an even balance on all sides of the door.

Use a Screwdriver and Remove the Screws

Step 3: Re-Installation of the Door Frame

If your frame is sagging or not properly sealed, you may need to re-install it to prevent drafts. Use a screwdriver and remove the screws holding the frame in place, then lift it out and level it before placing it back into position. Then, use shims to make sure it is properly sealed.

Step 4: Install Weatherstripping

Weatherstripping is designed to help seal the door frame from air leaks. Measure the perimeter of your door and buy a roll of weatherstripping that matches those measurements, then cut it to size and install it around the frame. A threshold seal will help to fill any gaps between the floor and the bottom of your door. Measure the gap first, then buy a threshold seal that fits properly. Cut it to size and install it along the base of the door frame.

Step 5: Caulk Cracks in Door Frame

If there are any visible cracks or gaps in the door frame, use caulk to fill them in. Clean away any dirt and debris from the area before applying the caulk. Check around your door lock set for any air leaks. If you find any gaps, use a caulking tube to seal them up.

Step 6: Install Door Sweeps

Door sweeps are designed to help seal the gap between your door and the floor. Measure the width of your door and buy a door sweep that matches those measurements. Install it along the bottom of your door frame for added protection against drafts.

After all the adjustments and installations, inspect the door frame one last time to ensure you have sealed any possible drafts. This will help ensure your home is warm and cozy for many years.

Use a Roll of Weatherstripping

If there are gaps around your windowsill or any other part of your home, you can also use door sweeps to help seal these areas. They are an easy and affordable way to prevent air leaks throughout your home.

Safety Tips for How to Fix a Drafty Door Frame

  1. Wear protective gear, such as gloves and safety glasses, when handling tools during installation.
  2. Ensure that any screws or nails you use are properly installed and secured before continuing to the next step.
  3. Never use a power drill on an unprotected door frame, as it can damage the surrounding area and cause injury.
  4. Ensure that any weatherstripping you use is of the proper size and fits snugly against the frame.
  5. When applying caulk, use it sparingly and evenly around the door frame to prevent air leaks.
  6. Measure your door frame twice before cutting with a saw or other power tool.
  7. If you are unsure how to perform any of the steps in this guide, it’s best to consult a professional for assistance.

By following these safety tips and instructions, you can safely and effectively fix your drafty door frame so that your home is warm and cozy all year round.

How Do You Identify Where the Draft is Coming From?

The first step to solving a drafty door frame is to identify the source of the draft. There are several possible sources, so it’s important to note any areas where air might enter your home from outside. Start by checking around your windows and doors for gaps, cracks, or holes in the wall or around the casing (the trim that holds the frame in place). No matter how small, any opening can be a source of air infiltration.

Gloves and Safety Glasses

For doors specifically, look at the weather stripping and threshold for any signs of wear or tear. If your door’s threshold is cracked or split, it could let cold air into your home. Likewise, if the weather stripping has come loose, gaps can occur between the door and the frame, allowing air to seep through.

Are Any Other Long-term Solutions to Prevent Your Door Frame From Becoming Drafty?

The good news is that fixing a drafty door frame doesn’t have to be a long-term inconvenience. There are some longer-term solutions you can consider that will help keep your door frame from becoming drafty in the future. One option is to weatherstrip the door with a flexible vinyl strip, foam, or felt.

This material is designed to fill the gaps around your door frame, creating a tight seal and preventing air infiltration. You can find weatherstripping at most hardware stores or online retailers.

Another option is to replace the door sweep on the bottom of your door frame with a new one. This helps ensure that unwanted air from outside won’t come into your home through the cracks at the bottom of the door. You can find these door sweeps in many hardware stores or online retailers.

Finally, consider installing a storm door over your existing door frame. This will provide an extra layer of protection from drafts and unwanted air infiltration. Storm doors are available in many sizes and materials, so you should be able to find one that fits your door frame.

Will You Need Professional Help to Fix Your Drafty Door Frame?

Generally, it’s not necessary to hire a professional when fixing a drafty door frame. Most of the above solutions are easy enough for even the least experienced DIYer to complete in an afternoon.

If you do decide that you need help with the job, however, plenty of professionals are available who can help ensure the job is done right. They can advise you on the best materials to use for weatherstripping, and they can also install a new door sweep or storm door for you if needed.

No matter what solution you choose, it’s important to take the time to fix your drafty door frame properly. Taking the time now will save you money in energy bills over the long run.

Are There Other Ways to Improve Your Home’s Energy Efficiency?

In addition to fixing a drafty door frame, there are many other ways to improve your home’s energy efficiency. One way is to install insulation in attics and crawl spaces, which helps keep warm air in during the winter and cool air in during the summer. You can also check for any areas of air infiltration around windows and doors and address them with weatherstripping or caulking.

Another great way to conserve energy is to install new windows and doors designed specifically for energy efficiency. These windows and doors can make a huge difference in your home’s energy efficiency, as they reduce the amount of air infiltration into your home.

Finally, you may want to consider upgrading your HVAC system. Installing a new energy-efficient HVAC system can help you save money on your monthly energy bills in the long run.

Are There Any Potential Health Risks Associated With Having a Drafty Door Frame?

Drafty door frames can cause a range of health issues. The cold air can seep into your home, leading to higher energy bills and creating an uncomfortable environment for those in the home.

If not addressed quickly and properly, drafty door frames may lead to respiratory problems due to the cold air breathed in or mold growth from the moisture that collects in door frames. To make sure your home is safe and comfortable, it’s important to fix any drafty door frames as soon as possible.

One way to do this is by installing weatherstripping around the frame. Weatherstripping can help seal the cold air from entering and keep warm air inside during colder months. You should also check to see if the door frame is warped. If it is, you must replace it before sealing the draft with weatherstripping.

Fixing a Drafty Door Frame is Easier


In conclusion, fixing a drafty door frame is easier than it may seem. Proper insulation and weatherproofing techniques can help to prevent heat loss or air infiltration. With the right materials, tools, and instructions, you can easily make your door frames more energy efficient and keep drafts at bay.
