How to Fix a Sticking or Squeaky Door (Every Cause, One Guide)

A door that announces every trip to the kitchen with a horror-movie creak, or one you have to shoulder-check shut, feels like a "someday" problem — until it isn't. The good news: doors almost never go wrong in complicated ways. They squeak, they sag, they swell, or their latch drifts out of line. Each of those has a clean, cheap fix, and once you can tell them apart you'll never pay someone to do this again.

This guide walks all of it in order — a 60-second diagnosis, the squeak fix, the sticking-door fixes (easiest to most involved), the won't-latch fix, and the one pro trick that solves more sagging doors than sanding ever will.

First, diagnose the symptom

Three different doors send three different signals. Match yours before you touch a tool:

The single most useful move is to find exactly where the door binds. Open and close it slowly and watch the gap — pros call it the reveal — between the door slab and the frame. Where the reveal disappears or you see a shiny, scuffed, or paint-worn stripe, that's your contact point. To be sure, rub chalk or a colored pencil along the suspect edge, close the door, and open it: the transfer mark shows you the exact high spot to address.

        A door sags AWAY from the top hinge,
        so it drops and drags at the OPPOSITE
        top corner. Lift it back with the
        long-screw trick — not the sander.

Fix 1 — Silence a squeaky hinge

A squeak is pure friction: metal rubbing metal because the hinge is dry, dirty, or lightly rusted. The fix takes minutes.

1. Lubricate the pin. Spray a silicone or dry PTFE (Teflon) lubricant onto the hinge pin and into the seam between the knuckles. Swing the door back and forth several times to work it in, then wipe off the excess so it won't collect dust.
2. If the squeak returns, clean the pin. Tap the hinge pin up and out with a nail and a few light hammer taps from below. Wipe off old grime and rust with a rag or fine steel wool, apply a thin coat of lubricant, and tap it back in.
3. Snug the screws. A loose hinge lets the knuckles grind unevenly — a hidden cause of squeaks. Tighten while you're there.

Don't reach for WD-40 here. The original formula is a water-displacing solvent: it quiets the hinge for a day or two, then evaporates and the squeak comes right back (and the residue attracts grit). For a fix that lasts years, use silicone, dry PTFE, or powdered graphite. In a true pinch, a drop of household oil, petroleum jelly, or even bar soap rubbed on the pin will hold you over.

Fix 2 — Tighten the hinges (start here for any drag)

Before you remove a single shaving of wood, do this — it solves a surprising share of sticking doors for free. Over years of slamming, hinge screws back out and the door sags away from the top hinge, dropping the opposite top corner into the frame.

Grab a screwdriver — not a drill, which strips and over-drives heads — and snug every screw on every hinge. Open and close the door; many "swollen" doors are suddenly fine. If a screw just spins in place without tightening, its hole is stripped out, which is exactly what the next fix cures.

The long-screw trick (the fix most people skip)

This is the move that separates a frustrating afternoon from a two-minute repair. When the top hinge can't hold because its screws are stripped or the door has sagged, replace one short screw in the top hinge with a 3-inch (75 mm) screw.

Here's why it works: standard hinge screws only bite into the thin door jamb. A 3-inch screw reaches past the jamb and into the wall framing (the stud) behind it. As you drive it home, it pulls the entire door up and back toward the hinge side — lifting that dragging top-latch corner clear of the frame and frequently re-aligning the latch at the same time.

Fix 3 — The swollen-in-summer door

If your door binds in humid months and frees up in winter, it's swelling, not failing. Wood is hygroscopic — it drinks moisture from humid air, expands, then shrinks back as the air dries. You have three options, in order of preference:

• Wait it out if the rub is minor — it'll likely ease when the season changes.
• Control the humidity with a dehumidifier or better ventilation; this also helps the rest of your home. (See why your house feels humid for the moisture side of the story.)
• Sand the high spot if it sticks year-round. Mark the contact point with chalk, sand it lightly with medium-grit paper on a block, and re-test often. Crucially, seal any bare wood you expose with primer or paint — an unsealed edge soaks up moisture and swells right back. An unpainted door edge is one of the most common reasons a "fixed" door starts sticking again.

Fix 4 — A door that won't latch or won't stay shut

Won't catch? The latch bolt is missing the hole in the strike plate. Smear a little lipstick or marker on the latch, close the door, and open it — the transfer mark on the strike plate shows whether the latch lands too high, too low, or short. Then either file the strike-plate opening a touch larger or unscrew and reposition the plate a few millimeters. In many cases, tightening the hinges and doing the long-screw trick raises the door just enough to re-center the latch with no plate work at all.

Swings open or shut on its own? The door isn't plumb — the hinges lean slightly. The quick carpenter's fix is to slip a thin cardboard shim behind one hinge leaf (behind the top hinge to make it swing closed, the bottom to make it stay open), or gently bend the hinge pin. Re-tightening square hinges usually solves it.

Fix 5 — Sand or plane (genuine last resort)

Only if the door still rubs after tightening and the long-screw trick should you remove material:

• Sanding handles a small high spot: medium-grit paper on a sanding block, a little at a time, re-testing as you go. You rarely need to take off more than a hair.
• Planing is for a badly swollen edge. Mark the high area, plane with the grain in thin passes, and stop the moment the door clears. Plane the hinge edge rather than the latch edge when you can, since it's easier to re-bevel.
• Always re-seal the bare wood you expose with primer/paint so it can't reabsorb moisture.

What it costs

When it's not really the door

A single door that sags or sticks seasonally is a confident DIY job. But step back and call a pro if you see the signs of a bigger problem:

Keep it from coming back

Doors drift out of true slowly, so the maintenance is light: once or twice a year, snug the hinge screws and give a dry silicone or PTFE shot to any hinge that's starting to talk. Keep exterior door edges sealed and painted so humidity can't swell them. It's the kind of tiny, high-payoff task that's easy to forget until the creak is back — which is exactly what a plan is for.

This pairs naturally with the rest of your seasonal upkeep: re-caulking and resealing around exterior doors lives on your fall maintenance checklist and month-by-month schedule, alongside replacing worn weatherstripping and re-caulking windows, doors & trim.
