A door that keeps swinging shut on its own can be incredibly annoying. Fortunately, this problem usually boils down to a couple common issues that are relatively easy to remedy. In most cases, a door that won’t stay open is caused by an imbalance in the door’s hinges, a weak door stop, or problems with the door frame itself. With some basic tools and DIY skills, you can troubleshoot the issue and fix a self-closing door so it operates smoothly.

Common Causes of Doors That Keep Swinging Shut
Before trying to fix a door that won’t stay open, it’s helpful to understand the most common underlying causes of the problem:
- Misaligned hinges: If the hinges are sagging or bent out of shape, it can create an imbalance in the door that causes it to swing closed.
- Worn out door stop: The small rubber or metal stop on the floor that keeps the door open can wear out over time and fail to hold the door.
- Warped door or frame: A warped, bent, or damaged door or frame can cause the door to swing rather than hang straight. This makes it continue moving to the closed position.
- Incorrect hinge type: Hinges that are too lightweight for the door will allow the door to overpower them and swing closed.
- Poor trimwork clearance: If the door or frame are sagging, the door may catch on surrounding trimwork causing it to swing shut.
Tightening Loose Hinges to Balance the Door
One of the first things to check if your door keeps swinging closed is whether the hinges are loose andsagging. If the hinges are misaligned or pulling away from the frame, it can create imbalance in the door. Here are some tips for tightening loose door hinges:
- Support the door while you remove weight from the hinges. Have someone hold the door up or place a doorstop underneath.
- Using a screwdriver, tighten all the loose screws in the hinges. Don’t overtighten, just tighten enough so they are snug.
- Check that each hinge leaf is sitting flush against the door frame. Tap any raised or misaligned hinges with a hammer to realign them.
- Add any missing screws to the hinge plates. Fill old screw holes with wood putty before driving in new screws.
- Consider replacing badly warped or damaged hinges with new ones of the proper size and strength.
Properly aligned hinges should allow the door to hang straight and stay in place rather than swinging closed. Make sure to tighten the top and bottom hinges for the best results.
Replacing a Worn Out Door Stop
If tightening the hinges doesn’t solve the problem, the next thing to check is the door stop. This small piece of hardware on the floor stops the door from swinging too far open. But door stops can wear out or become damaged over time, causing them to no longer keep the door in place.
Replacing a door stop is an easy, inexpensive DIY fix:
- Remove the old stop from the floor. Usually this just involves removing the small screw.
- Purchase a new stop that matches your existing hardware finish.
- Position the stop in the same location and mark spots for the screw holes.
- Pre-drill the screw holes into the floor to avoid splitting the wood.
- Drive in the screws to attach the new stop securely to the floor.
- Test that it stops the door securely without needing to overtighten the screws.
Getting a slightly larger or heavier duty door stop can provide a stronger barrier to keep the door open. Just take care not to overtighten it too much.
Adjusting a Warped Door or Frame
If your door seems to be warped or sagging, or the door frame is damaged, it can lead to the door swinging closed on its own. Trying to adjust or repair the door itself is advanced DIY work. But here are some steps you can take to deal with a warped door frame:
- Inspect the door frame, especially the top and sides, for any warping or damage.
- Use wooden shims to level any areas that are sagging. Tap them gently into gaps with a hammer.
- Add additional shims until the frame sits flush and level all the way around.
- Secure shims with wood glue or nails to hold them in place.
- Use wood filler to patch any remaining gaps prior to repainting the frame.
Dealing with a badly warped door usually requires replacing the entire door. But shimming and adjusting the frame can help compensate for minor warping issues.
Installing Stronger Hinges
If your door seems to be too heavy for the existing hinges, an easy fix is to upgrade the hinges themselves. Here’s how:
- Choose hinges rated for the thickness and weight of your door.
- Make sure the hinge screws are long enough to secure the new hinges.
- Remove existing hinges and fill old screw holes if needed.
- Position the new hinges in the same location and install them with screws.
- Make any adjustments needed so the door hangs straight.
Going to a thicker gauge hinge or using ball bearing hinges can provide much smoother swinging and keep a heavy door from closing on its own.
Adjusting the Door Trim Clearance
In some cases, a door that sticks and self-closes is due to insufficient clearance with the surrounding door trimwork. If the door rubs or catches on the trim, it can lead to it swinging shut.
To adjust the door trim:
- Identify where the door is rubbing against the trimwork.
- Use a block plane or rasp to shave off a bit of the trim to widen the gap.
- Continue slowly removing material until there is 1/8″ to 1/4″ clearance around the door.
- Use a chisel to notch out the strike plate area so the door latch can enter freely.
- Make test opens and closes to ensure the door swings freely without catching.
Careful trimwork adjustment prevents the door from binding and allows smooth operation. Minimal clearance is ideal for both appearance and proper operation.
Lubricating Sticky Hinges
Hinges that have become stiff can also cause doors to swing shut instead of staying put. Regular hinge lubrication prevents this sticking and friction. Here’s how to lube door hinges:
- Open the door so you can access the hinges.
- Use a rag to clean dirt or debris out of the hinges.
- Apply a few drops of lightweight machine oil or lubricant spray to the hinge joints.
- Allow it to penetrate for 10-15 minutes then wipe away any excess.
- Open and close the door a few times to distribute the lubricant.
- Make sure the door now swings freely without catching or sticking.
This quick hinge lubrication can eliminate squeaks and restore smooth operation to keep the door properly balanced.
When to Call a Professional
While many door issues can be addressed with DIY repairs, there are times when it pays to call in a professional:
- The door or frame are severely warped and need replacement.
- The door jamb is damaged and needs extensive repair.
- There are concerns about the door being properly level and secure.
- There are problems with the alignment of the entire doorset in the frame.
- You want to upgrade or replace the entire door and hardware.
A trained carpenter or door technician has the expertise to handle major door repairs or installation. They can also provide guidance on upgrading to a door that operates smoothly and seals properly against noise, drafts, and weather.
Conclusion
Doors that constantly swing closed quickly go from a mild annoyance to a huge headache. But in most cases the problem can be easily diagnosed and corrected with basic DIY techniques. Tightening loose hinges, replacing a worn door stop, and adjusting surrounding trimwork are good places to start. More serious issues like warped doors or frames may require calling in a professional. But hopefully these tips will allow you to get your door operating smoothly once again so it stays exactly where you want it.
