How to Fix a Sticking Door: 8 Proven Ways to Get It Swinging Smoothly

There is nothing more annoying than a door that scrapes, drags, or flat-out refuses to latch. Whether it is an interior door that swelled up during a humid summer or an entry door that has sagged on loose hinges, the good news is that learning how to fix a sticking door is one of the easiest DIY repairs you can do. Most fixes take under an hour and need nothing more than a screwdriver, some sandpaper, and a little patience.

This guide walks you through exactly how to fix a sticking door with 8 proven methods, from five-minute tweaks to planing a swollen edge. Start with the easiest fixes first — most sticking doors are solved in the first two steps.

Why Doors Stick: The 4 Most Common Causes

Before you pick up a tool, it helps to understand what causes a sticking door in the first place. Finding the root cause when you learn how to fix a sticking door tells you which method to try first.

Humidity and wood swelling. Wood absorbs moisture from the air, so doors near bathrooms or exposed to weather can swell enough to jam in the frame — which is why doors often stick in summer and swing freely in winter.

Loose or sagging hinges. Over thousands of open-close cycles, hinge screws loosen and the door tilts downward — even 1/8 inch of sag can make the top rub against the jamb. The most common cause, and the easiest fix.

Misaligned strike plate. If the door swings freely but will not latch, the latch bolt is hitting the edge of the strike plate instead of sliding in. This needs only a small adjustment of the plate.

House settling. As homes settle, frames shift slightly out of square and a once-fine door starts rubbing — usually gradually.

Tools and Materials You Will Need

You probably own most of what this job requires. Gather these before you start learning how to fix a sticking door, so you do not have to hunt for tools mid-repair:

• Phillips and flat-head screwdrivers (or a cordless drill)
• 3-inch wood screws (to replace short hinge screws)
• Wooden golf tees or dowels plus wood glue (for stripped screw holes)
• 80- and 120-grit sandpaper or a sanding block
• A small hand plane or belt sander (only for stubborn swelling)
• Silicone spray lubricant or powdered graphite
• A pencil (for marking rub spots)
• Exterior-grade primer and paint or polyurethane (for sealing)

How to Fix a Sticking Door: 8 Proven Methods

Work through these methods in order. Each one builds on the last, and there is no point sanding or planing a door if a loose hinge is the real problem. Most homeowners who learn how to fix a sticking door find they never need to go past Method 2.

Method 1: Tighten the Hinge Screws

Close the door slowly and watch the gap between the door and the frame. If the gap narrows toward the top, the hinges have loosened and the door is sagging. Open the door and check every hinge screw — at least one is usually loose.

Tighten every screw on every hinge, both the ones in the door and the ones in the frame. Use a screwdriver rather than a drill so you feel how much grip is left. Test the door after each hinge — usually this is enough: the door lifts back into alignment and swings freely. It is the first trick in every guide on how to fix a sticking door for a reason.

Method 2: Drive Longer Screws Into the Top Hinge

If tightening did not fully solve the sag, the original hinge screws are probably too short: most builder-grade doors are hung with 3/4-inch screws that grip only the thin jamb, not the framing behind it. Remove one screw at a time from the top hinge on the jamb side (never all at once, or the door will fall) and drive a 3-inch wood screw in its place until the hinge leaf sits flat. Test the door; if it still drags, repeat with a second screw. This single trick fixes a surprising number of sticking doors permanently, which is why every guide on how to fix a sticking door includes it.

Method 3: Adjust the Strike Plate

Some doors swing perfectly but will not latch — the latch bolt hits the edge of the strike plate instead of sliding in. Loosen the plate’s two screws, shift it a millimeter or two in the needed direction, and retighten while holding it in place. For larger misalignment, file the edge of the strike-plate opening with a small metal file. If you are learning how to fix a sticking door that will not latch, always check this before sanding anything.

Method 4: Lubricate the Hinges

Stiff, dry hinges can make a well-aligned door feel like it is sticking. Spray a silicone-based lubricant into the hinge barrels, then swing the door back and forth a dozen times to work it in. Wipe away the excess with a rag.

Avoid cooking oils or heavy greases — they collect dust and eventually gum up the hinge worse than before. Dry hinges are one of the most overlooked causes of a sticking door, so this step belongs in every how to fix a sticking door routine. Make lubrication a yearly habit.

Method 5: Mark and Sand the Rubbing Spots

If the hinges are tight and the latch is aligned but the door still drags, you need to remove a small amount of material from the door itself. Close the door and slide a piece of paper around the edges — wherever it binds, the door is rubbing. Mark those spots with a pencil.

Open the door and sand the marked areas with 80-grit sandpaper, working with the grain. Check your progress often with the paper test — remove the absolute minimum of wood. Smooth with 120-grit once the door swings freely. This is the gentlest material-removal method for anyone learning how to fix a sticking door, and it is all most doors ever need.

Method 6: Plane the Edge of the Door

For doors swollen badly enough that sanding would take forever, a hand plane removes thin, even shavings quickly. Among all the methods for how to fix a sticking door, planing removes material the fastest — so set a shallow cut, work from the outer edge toward the middle to avoid splintering corners, and test-fit often. No plane? A belt sander with 80-grit paper works too; just keep it moving. Once the door swings freely, smooth the edge with 120-grit sandpaper and seal the bare wood (Method 8), because an unsealed edge will absorb moisture and swell right back up.

Method 7: Repair Stripped Screw Holes

When hinge screws spin freely without biting, the screw holes are stripped. Coat a wooden golf tee or short dowel in wood glue, tap it into the hole, and let it dry completely. Trim the plug flush, drill a small pilot hole, and drive the screw in — it now bites into solid new wood. Give the glue at least a few hours to cure, overnight if you can.

Method 8: Seal the Door Against Moisture

The final step protects your repair from coming back, and it is the step most people skip when learning how to fix a sticking door — which is why their doors stick again next year. Bare wood, especially freshly sanded or planed edges, soaks up humidity and swells. Seal every exposed surface: top and bottom edges (often left unfinished), planed areas, and any bare spots.

For interior doors, primer plus paint is enough; for exterior doors, use exterior-grade primer plus two coats of paint, or spar polyurethane for a natural-wood look. As the experts at This Old House recommend, sealing all six sides of a door is the best long-term defense against seasonal sticking — do it in the driest part of the year, when the door has shrunk to its smallest size.

How to Fix a Sticking Door: FAQ

Why does my door stick only in summer?

Summer air carries far more moisture, and wood doors absorb it and expand — even 1/16 of an inch is enough to jam a tight frame. This seasonal pattern points to moisture, so remove the swelling (Methods 5 and 6), then seal the wood (Method 8) so it cannot absorb moisture next summer.

Can I fix a sticking door without removing it from the hinges?

Yes. Methods 1 through 5, 7, and 8 can all be done with the door hanging in place. Only planing (Method 6) is sometimes easier with the door removed and laid on sawhorses, but it can also be done in place if you protect the floor. That is one reason how to fix a sticking door is such a popular DIY project — no door removal required.

How much wood should I sand or plane off a sticking door?

In most cases, removing 1/32 to 1/16 of an inch is plenty. Take off a little, test the door, and repeat — remember that doors swell and shrink with the seasons, so removing too much in summer leaves a drafty gap in winter. Aim for a consistent 1/8-inch gap around the door.

When should I call a professional instead of doing it myself?

Call a pro if the frame is badly out of square, if you suspect structural or foundation issues, or if an expensive solid-core or historic door is involved. For everything else — loose hinges, sticky latches, swollen edges — this guide on how to fix a sticking door has you covered.

Final Thoughts

A sticking door is annoying, but rarely serious. Nine times out of ten, the fix is a loose hinge screw or a misaligned strike plate — jobs that take minutes and cost nothing. Even a swollen door surrenders to a little sanding and a good coat of sealer. Now that you know how to fix a sticking door, check the other doors in your house; the ones starting to drag will thank you for the attention.

Seasonal swelling returns every year, so this is a skill you will use again and again.
