You know that sound. That annoying scrub-scrub-scrub against the floor or the way you have to practically shoulder-check your own front door just to get the deadbolt to click. It’s infuriating. Most people assume the house is settling or the wood has warped beyond repair, so they call a contractor or start looking up the price of a brand-new pre-hung door.
Stop.
Honestly, before you spend three hundred bucks on a door you don’t need, you’ve got to try the one door hinge adjustment hack that pros use but rarely talk about. It sounds stupidly simple. It involves a long screw and about five minutes of your time. No sanding, no planing, and definitely no expensive power tools required.
The Physics of the "Sag"
Doors are heavy. A standard solid-core interior door can weigh 40 pounds, while a beefy mahogany front door might hit 100. Over time, gravity is basically your enemy. The top hinge takes all the tension, and the screws—usually those tiny one-inch ones that come in the box—start to pull out of the soft pine framing behind the drywall.
When that top hinge pulls away just a fraction of an inch, the whole door tilts. The top corner hits the jamb, and the bottom corner drags on the rug. It's a leverage game. You don't need to shave the wood down; you just need to pull the hinge back where it belongs.
This Door Hinge Adjustment Hack is All About the Long Screw
Forget the fancy shims for a second. If you look at your hinges, you’ll see three or four screws. In almost every standard residential build, those screws are only biting into the door jamb—the thin piece of decorative wood that makes up the door frame. They aren't actually hitting the "meat" of the house, which is the 2x4 or 2x6 stud framing.

Here is the hack: replace the center screw of the top hinge with a 3-inch or 3.5-inch wood screw.
By using a screw long enough to pass through the jamb, through the gap, and deep into the structural wall stud, you are effectively "anchoring" the door back into the skeleton of the house. As you tighten that long screw, it pulls the hinge—and the door attached to it—back toward the wall.
How to do it without stripping everything
- Open the door wide so you have room to move.
- Remove the middle screw from the top hinge (the one closest to the wall).
- Drive a 3-inch #8 or #9 wood screw into that hole.
- Watch the gap. As you tighten, you’ll literally see the door lift off the floor or move away from the strike jamb.
You have to be careful, though. If you go full-throttle with an impact driver, you can actually pull the jamb so far that the door won't close at all because it's now too tight on the hinge side. It’s a game of quarter-turns. Snug it up, check the swing, then give it another twist if the gap is still wonky.
Why Shimming is Usually a Waste of Time
A lot of old-school guys will tell you to take the hinge off and put a piece of cardboard or a cereal box behind it. This is called shimming. It works if the door is rubbing on the hinge side, sure. But 90% of the time, the problem is the sag. Shimming a sagging door just pushes the whole thing further into the strike zone, making the sticking problem even worse.
The door hinge adjustment hack using long screws is the "pull" method. Shimming is the "push" method. Unless your house was built perfectly square (spoiler: it wasn't), you usually need the pull.
What if the Screw Hole is Already Stripped?
Sometimes you pull out that old screw and a bunch of wood dust falls out like a tiny desert. That's bad news. It means the wood fibers are shredded and there’s nothing for even a long screw to grab onto.
Don't panic.
Grab some wooden toothpicks or a couple of wooden matchsticks (break the heads off first, obviously). Dip them in a little wood glue, jam them into the hole, and snap them off flush. Now you’ve created new "meat" for the screw to bite into. Wait about 20 minutes for the glue to get tacky, then drive your long screw in. It’ll hold better than the original did when the house was new.

The Bending the Knuckle Trick (For the Brave)
Okay, let’s say the long screw didn't quite get you there. Maybe the door is still rubbing at the very top. There is a secondary door hinge adjustment hack that feels like you're breaking something, but it's a legitimate locksmith move.
You use a crescent wrench to slightly bend the hinge "knuckles."
- Close the door.
- Pop the pin out of the problematic hinge.
- Take your adjustable wrench and slide it over the knuckles on the jamb side.
- Give it a tiny, tiny nudge toward the direction you want the door to go.
- Put the pin back in.
This essentially changes the pivot point of the door. It's aggressive. I wouldn't do this on a delicate vintage brass hinge because you might snap it, but for a standard steel hinge from a big-box store? It’s a lifesaver. Gary Katz, a well-known finish carpentry expert, has demonstrated this technique for years. It’s the difference between a door that latches with a satisfying click and one that you have to kick shut.
Common Mistakes to Avoid
Don't use drywall screws. Seriously. People do this because they have them lying around in a kitchen drawer. Drywall screws are brittle; they are designed to hold paper and gypsum, not the lateral shear force of a swinging 80-pound slab of wood. They will snap, and then you’ll have a hardened steel stump stuck in your wall stud that you can't drill out. Use construction screws or deck screws. They are designed to bend slightly under pressure rather than snapping.
Also, check your hinges for "slop." If the pin itself is wobbling inside the hinge, no amount of screwing or bending is going to fix that. That’s just a worn-out hinge. If you see metal shavings or "black dust" around the hinge knuckles, the metal is grinding away. At that point, the hack won't save you; you need to spend the $15 on a new set of hinges.
Real-World Results
Think about the "strike plate"—that metal bit on the frame where the latch goes. If you look at yours and see scratch marks above or below the hole, your hinges are the culprit. Fix the hinges, and the latch magically aligns. You don’t need to file down the metal strike plate. You don't need to move the strike plate up or down and leave a bunch of ugly holes in your wood.
Most people spend hours trying to fix the symptoms (the latch, the rubbing wood) instead of the cause (the hinge sag).

Actionable Steps to Fix Your Door Today
- Check the gap: Close the door and look at the "reveal" (the space between the door and the frame). If it's wider at the top than the bottom, you have a sag.
- Buy the right hardware: Pick up a small pack of 3-inch #9 wood screws. Torx head (star drive) is better than Phillips because they won't strip while you're driving them into an old, dry stud.
- The "One-at-a-Time" Rule: Never take all the screws out at once. Do one screw in one hinge, tighten it, and test the door.
- Lubricate while you're there: Since you’re messing with the hinges anyway, pull the pins one by one and wipe them down with a little lithium grease or even a bit of WD-40 Specialist Silicone. Avoid regular WD-40 if you can, as it attracts dust over time and can turn into a sticky mess.
- Verify the frame: If the long screw doesn't move the door, your house might have a double-stud gap that's too wide. In that rare case, you might actually need to remove the casing and shim the gap properly, but try the screw hack first. It works in about 9 out of 10 homes.
Once you get that first door swinging perfectly with just a flick of your pinky, you're probably going to walk around your entire house fixing every other door. It's strangely addictive. You’ll realize that the "house settling" excuse was mostly just an issue of short screws and gravity doing what it does best.
