A door that will not stay open, swings shut on its own, or sticks badly enough that you have to shoulder it open is not a minor inconvenience, it is a sign something is out of alignment. Most interior door problems come down to four things: loose hinges, a shifted frame, humidity swelling, or a latch that no longer lines up with the strike plate. All four are fixable without calling anyone.
Step 1: Figure out what the door is actually doing
Close the door slowly and watch where it rubs or catches. If it drags at the top on the latch side, the hinge side is sagging. If it sticks along the bottom edge, the house may have shifted or humidity expanded the wood. If it latches but only barely, the latch bolt and strike plate are misaligned. If it swings open or closed on its own, the door is not hanging plumb.
Each problem has a specific fix. Diagnosing correctly saves you from doing extra work that does not solve the issue.
Step 2: Tighten the hinges first, this fixes more problems than you expect
Loose hinge screws are the most common cause of sagging doors. Over years of use the screws strip out, the hinge pulls away from the frame slightly, and suddenly the door drags. Open the door, check every hinge screw with a screwdriver. If any turn freely without tightening, the hole is stripped.
The fastest fix for a stripped hinge screw hole: dip a wooden toothpick in wood glue, snap it off in the hole, let it dry for an hour, then drive the screw back in. The wood gives the screw something to bite into. For badly stripped holes, a longer 3-inch screw driven through the hinge and jamb into the framing behind it is more permanent and very effective. This is the fix most carpenters reach for first.
Step 3: Fix a door that self-swings (not plumb)
If the door swings open or rolls shut without being touched, the hinges are not perfectly aligned and gravity is doing the work. The easiest fix without removing the door: place a thin shim (a playing card, a piece of cardboard, a matchbook cover) behind one of the hinges on the side that needs to be pushed out. Unscrew the hinge leaf from the jamb, slide the shim behind it, and rescrew. This pivots the door slightly and changes how gravity acts on it.
Start with the top hinge for a door that swings open, bottom hinge for a door that swings shut. You may need to try a thicker or thinner shim to get it right. It takes ten minutes to test both options.
Step 4: Fix a sticking door (humidity or paint buildup)
Doors that stick in summer and not in winter are almost always swollen from humidity. Mark where the door is sticking with a pencil by rubbing it along the edge while the door is closed, then open it and you can see where it made contact. Sand that area down with 80-grit sandpaper on a block, remove just enough material to get clearance, and seal the exposed wood with primer and paint. Bare wood absorbs moisture even faster than painted wood.
If humidity is not the issue and the door has been painted many times, layers of paint build up on the edges and in the hinge mortise. Strip the excess paint with a utility knife or a pull scraper to restore the original fit. A properly fitted door should close with just light resistance.
Step 5: Fix a latch that misses the strike plate
Rub lipstick or a pencil on the latch bolt, then press the door closed. The mark left on the strike plate shows exactly where the bolt is hitting. If it is off by less than an eighth of an inch, file the strike plate opening in the direction needed with a metal file. If it is off more than that, unscrew the strike plate, chisel the mortise in the new direction, and move the plate. Drill a new pilot hole for the screw and fill the old one with a toothpick and wood glue.
For these kinds of jobs, having a good screwdriver set with proper grip and the right Phillips sizes matters more than people think. Cam-out (where the screwdriver slips in the screw head) strips screws and makes a simple job into a frustrating one. The HOTO compact tool set is built around exactly this kind of precision household work.
When to call someone
If your door frame has a visible gap at the top or a diagonal crack running from a corner into the wall, the house frame may have shifted significantly. That is worth a conversation with a contractor to rule out foundation movement before you patch and repaint. For everything else, hinges, sticking, latch alignment, this is firmly in DIY territory.
Small home repairs like these add up to real savings over a year. The Broke Mom Home Reset ($17) is built around that idea: fix the small things yourself, redirect that money, and stop letting minor problems turn into expensive ones because they sat too long.
