Doors that close by themselves definitely rank high on the list of crazy house problems. And it’s not just your house. We’ve all been in rooms where doors suddenly close and scare us. What causes it?
Doors close by themselves for various reasons. Doors have many moving parts. When they close by themselves, it’s usually because one of these moving parts has failed or worn out, causing the door to no longer close properly.
For most people, the only time they think about doors is when they need to open or close them, but what happens when a door closes by itself? Is something wrong with the door, or is there another explanation? This article examines why doors close by themselves and explains how to fix the problem.

Reasons why doors close by themselves
There are several possible reasons why doors close by themselves. Keep reading to see what seems most likely in your situation.
It’s just the wind. Have you ever been startled by a door closing by itself? It’s a strange feeling, and it happens to most of us. Doors close for many reasons, but one of the most common is the wind. Basement doors and windows constantly open and close by themselves. It’s just the wind.
Changes in air pressure. This phenomenon is caused by a difference in pressure between two different rooms. When you open a door between two rooms (e.g., an exterior door), a pressure imbalance is created, causing the door to swing open and close.
When someone opens a door, they create an area of low pressure behind it. This low-pressure area sucks in ambient air into the room, which is then expelled when the door closes. This process causes doors to close by themselves.
One of the most common reasons for doors to close by themselves is that the house has settled. This can be attributed to age or a recent seismic event. The problem can be as simple as the door getting off track.
Your door and frame are not aligned. When a door closes by itself, it is usually because the door and frame are not aligned. The door should be flush with the frame when closed. This prevents the door from slamming shut. The other reason doors close by themselves is a loose hinge or handle that needs to be tightened.
Hinges are not aligned. If the hinge is higher on one side than the other, the door will swing shut by itself. This can happen if you have a small door opening or uneven doors, such as one that is higher than the other. Next time you experience a door closing by itself, check if the hinges are aligned or not.
How to prevent a door from closing on its own
Fortunately, there are several methods you can use to prevent a door from closing on its own, and most of them are easy to implement.
Use a door wedge. Door wedges are a simple yet effective method to prevent doors from swinging shut on their own. They work by inserting a wedge into the door frame to block the door from closing. For those who get scared when doors close behind them or have pets that run into the room thinking you’ve left, this is a useful method to prevent that.
Tighten your hinges. If you’re looking for a way to prevent your door from closing on its own, you may need to tighten the hinges. The first step is to remove the door from its hinges and then tighten the screws. If you find that screws are missing, replace them with new ones. You can also apply lubricant or Vaseline to the hinges to help them move more smoothly.
Place a cardboard spacer under the hinge. The easiest way to prevent a door from slamming shut is to place a small washer or spacer under the hinge. This works particularly well for pocket and double doors, as they tend to swing shut.
Place a small piece of cardboard, wood, or even a thin book under the hinge to prevent the door from closing completely. If you have tall doors that tend to hit walls with the bottom edge, add an additional washer on the opposite side of the hinge.
Bend the hinge to increase friction. To increase friction in the door hinge and prevent the door from closing in this way, follow these steps:
- Remove the hinge pin: Get a pair of locking pliers, wrap the jaws of the pliers around the hinge pin, and clamp them tight. Turn the pliers clockwise to loosen and remove the hinge pin from the door. Tap the end of the pliers with a hammer if needed to loosen it.
- Bend the removed hinge pin: After removing the hinge pin from the door hinge, place a large C-clamp around the hinge pin to hold it in place. Bend the hinge pin using a vise or pliers. If any of the ends of the hinge pin are damaged, use a hacksaw blade to cut off any protruding metal before reinstallation.
- Reinsert the hinge: It’s effortless to remove the pin, but it can be tricky to put the pin back together. Apply a small amount of lubricant to one side of the hinge pin to help it slide in more easily. Then, you’ll need to insert the hinge pin at an angle into its socket and press the hinge pin into the socket with force.
- Repeat until the door no longer closes: Repeat the above steps until the door no longer closes by itself. If the door continues to move freely and close again, you may need to call a professional.
How to prevent a door from opening on its own
Some people have trouble with doors opening on their own in addition to problems with self-closing doors. Here are some ways you can make sure your doors stay closed.
Use a door stopper. Door stoppers are used to prevent automatic opening or closing of doors. The main purpose of door stoppers is to hold the door open and prevent it from closing. They can be placed anywhere on the floor or wall and are commonly used in hospitals and schools. Door stoppers do not require any special tools for installation and are a quick method to prevent a door from closing by itself.
How to fix tight doors
If your doors are snug in the frame, it could prevent them from opening and closing properly. Here’s what you can do to fix this problem.
Tighten the hinges. The hinge is exposed to all kinds of weather, wear, and other elements that can cause problems with tight doors. Minor problems with the hinge can lead to all sorts of issues with interior doors.
If you notice that your doors are becoming harder to open or require more force to close than before, then it’s time to tighten the hinges.
- Remove the screws on the hinges.
- Reinsert the screws and test the door.
- If the door still sticks, repeat the process until it fits snugly.
Replace the middle or bottom hinge. If the door is difficult to open, it may be because the hinges are too tight. You can fix this by replacing either the middle or bottom hinge, depending on which one is causing the problem. Replacing a hinge is a simple process that can be done in minutes with just a few tools.
Follow these steps to replace the hinge and fix your door:
- Remove the screws from the hinge.
- Take out the old hinge pin.
- Insert the new hinge pin.
- Replace the screws on the hinge.
- Test if the door swings correctly.
Once you’ve replaced the hinge, test the door to ensure it opens and closes smoothly. If not, repeat these steps until the door is functioning properly again.
Repair your frame. The door of a house should be as strong and tight as possible. However, over time, the wooden post loosens. If the door is not attended to in time, the problem worsens from day to day. Eventually, you may need to replace it with a new one.
Here are some things you can do at home to repair a loose door frame:
- Identify the problem – Your door may be too snug because the jamb (the frame around the door opening) is not square.
- Use a shim to fix the frame – This will help pull the door back and make it fit better.
- Check the screws on your hinges – They may need to be tightened or replaced.
- Make sure your threshold is level – If not, you can adjust it with shims.
- Seal the door frame if necessary to create a tight seal and keep drafts out.
Use a sander to smooth your door. Belt sanders are used to repair doors in homes that do not close properly. The problem occurs when the wood is uneven, causing the door to stick and stick.
If the door is sticking, it may be because it doesn’t quite have the right size for the opening. A belt sander can be used to sand down the door so that it fits better in the opening.
Get a belt sander and smooth the door so that it opens and closes more easily. Sand it with the grain of the wood to avoid damage to the surface. Be careful not to remove too much material, or else you may need to purchase a new door.
Sanding the door also helps to remove scratches or stains on the surface. Finally, apply a coat of paint or sealant to protect the wood from moisture and fading.
