Door Won't Close or Latch? How to Fix a Sticking Door
A door that won't close or latch is one of those problems that starts small and gets annoying fast. You're slamming it a little harder each time, or you've stopped closing it at all because it takes three tries. I've been fixing doors in Phoenix's East Valley for 15 years, and I can tell you this: most sticking door problems are fixable in under an hour, and some you can handle yourself.
The good news is that a door that won't close or latch almost always has one of three root causes: hinge problems, wood swelling or settling, or a misaligned strike plate. Once you know which one you're dealing with, you can either fix it yourself or know exactly what to tell a handyman.
Diagnose Where It's Sticking
Don't guess. You need to know exactly where the door is binding against the frame.
Open the door and look for where it's dragging — is it the top corner, the latch side, the bottom? Sometimes it's obvious. Sometimes it's subtle. Here's the trick: grab a piece of cardboard (a cereal box works) and slide it between the door and frame at different spots while the door is closed. When the cardboard stops moving, that's where the gap has disappeared. That's your problem spot.
Do this at the top, middle, and bottom of the door on both sides. It takes two minutes and tells you everything you need to know.
Fix 1 — Tighten Loose Hinges
Loose hinge screws are the most common culprit. A sagging door that rubs the top corner of the frame? Ninety percent of the time, it's hinges.
Get a screwdriver and tighten every single screw on every hinge. Don't skip the ones that seem tight. Go around twice — sometimes the first pass settles things and the second pass gets them properly snug.
Now test the door. Does it close smoothly? If yes, you're done. If not, keep reading.
Here's what happens sometimes: the screw holes get stripped out, so the screw just spins and doesn't tighten. You can fix this. Unscrew it, fill the hole with wood glue, stick a toothpick or two in there, let it dry for 20 minutes, then re-drive the screw. The toothpick gives the screw something to bite into.
If you're really serious about fixing this right, replace those short little hinges screws with 3-inch wood screws that actually reach the stud. The difference is night and day. Most hardware store hinges come with half-inch screws that barely grab anything. I've been telling people this for years — use the longer screws and your door stays put.
Fix 2 — Plane or Sand the Binding Edge
So the hinges are tight, but the door still sticks. That means the door itself has swollen or the frame has settled, and now wood is rubbing against wood.
Here in Phoenix, we get humidity in the monsoon season (July and August are rough), and doors swell. Other times of year they shrink. It's normal. The problem is when the door swells and nobody addresses it — then it stays in the rubbing position even after the humidity drops.
The fix is to remove a thin layer of material from the binding edge — usually the top or the latch side. You can use a hand plane if you know how to use one, but a belt sander works faster. Makita makes a decent cordless one if you're buying. Use 80-grit sandpaper and make small passes. Sand for 30 seconds, close the door and test. Sand for 30 seconds more, test again. The goal is to remove just enough material so the door swings freely but still closes tight against the weatherstripping.
Don't get aggressive. I've seen people remove half an inch of material and end up with gaps around the door. A couple millimeters is all you usually need. Once you're done sanding, prime and paint the bare wood. That seals it and slows down future swelling.
Fix 3 — Adjust or Enlarge the Strike Plate
The door closes fine, but the latch bolt won't catch — it just pushes against the frame and bounces back out. That's a strike plate problem.
Here's the diagnostic trick: rub lipstick (or a crayon if you don't have lipstick) on the latch bolt, then close the door firmly. Open it and look at the strike plate. The lipstick mark shows exactly where the latch is hitting. If it's off by a quarter inch, you need to move the strike plate.
Loosen the two screws holding the strike plate, slide the whole thing slightly in the direction the mark indicates, and re-tighten. Test the door. Usually one adjustment does it.
If the latch mark is only a tiny bit off, you can also use a file to enlarge the hole in the strike plate slightly. File the hole wider in the direction the latch needs to go. It's quick and avoids extra holes in the frame.

Frequently Asked Questions
Why won't my door close all the way?
Most likely causes: loose hinge screws causing the door to sag, wood swelling from humidity, or a misaligned strike plate. Tighten the hinges first — that fixes the issue in about 30% of cases. If it still sticks, use the cardboard test to pinpoint whether it's binding at the top, middle, or bottom.
How do I fix a door that sticks in the summer?
Doors swell in summer humidity — Phoenix especially gets that monsoon moisture in July and August. Sand or plane the binding edge lightly, then seal the exposed wood with primer and paint. That slows future swelling. If it happens every summer, it's a sign the door needs attention before the season hits.
How do you fix a door that won't latch?
The latch bolt is missing the strike plate hole. Either shift the strike plate to align with the latch (the best fix), or file the hole slightly larger if only marginally misaligned. Use the lipstick trick to see exactly where the latch is hitting.
