Fix a Door That Rubs or Sticks

If your interior door suddenly started sticking, rubbing, or needing a shoulder check to close, you are not alone. Houses move. Humidity swells wood. Hinges loosen. The good news is many sticking doors are an often 10 to 30 minute fix once you figure out where it is rubbing.

This guide walks you through a simple “find the cause first” process, then the right fix: tighten hinges, tweak alignment with a shim, adjust the strike, or plane or sand for a clean, even reveal (that consistent gap around the door).

Safety and quick reality check

• Pinch points are real. Keep fingers clear when testing swing and latch alignment.
• Lead paint note: If your home is pre-1978 and you are sanding or scraping paint, assume lead may be present. Use a HEPA vac, contain dust (plastic, cleanup, and careful disposal), and wear a P100 or HEPA-rated respirator. In some areas, lead-safe work practices are legally required. If in doubt, follow EPA RRP guidance or hire a certified pro.
• Go from reversible to permanent. Tighten screws before you start removing wood. You can always plane later. You cannot un-plane.

Tools and materials (pick what matches your fix)

• Phillips screwdriver or drill/driver with clutch
• 4 ft level (or a shorter level plus a straightedge)
• Pencil
• Masking tape or painter’s tape
• Small shims (wood or composite)
• Utility knife
• Hammer and nail set (for hinge pins if needed)
• Block plane or hand plane (or a power planer if you are experienced)
• Sandpaper (120 and 180 grit) and sanding block
• Longer wood screws (commonly #9 or #10, about 2-1/2 in to 3 in, sized to your hinge holes)
• Touch-up paint or clear finish for the trimmed edge

Step 1: Find exactly where it rubs

Before you touch a screw, do a quick “detective lap.” You are looking for the contact point and the pattern of the problem.

Fast ways to spot the rub

• Look for shiny spots. Rub marks often look polished, scuffed, or slightly darker on the door edge or jamb.
• Tape test: Put painter’s tape along the door edge where you suspect rubbing. Open and close the door a few times. The tape will wrinkle or tear where it contacts.
• Pencil scribble test: Lightly scribble pencil on the door edge near the suspected area. Close the door. The pencil will transfer to the jamb at the rub point.
• Feel the reveal: Run your fingers along the gap. A tight spot will feel obvious.

Quick checks people forget

• Check the floor and threshold. A new rug, thicker carpet pad, or a raised threshold can make a door “stick” at the bottom even if the sides look fine.
• Check for paint ridges. A bead of paint on the door edge, stop molding, or hinge barrels can rub like sandpaper. Scrape or sand paint buildup before you start removing wood.

Step 2: Match the symptom to the likely cause

Most sticking doors fall into a handful of patterns. Find yours below, then jump to the fix section.

Common rub patterns

• Rubs at the top latch-side corner: Door sag from loose screws, worn hinges, or a hinge-side jamb that has shifted.
• Rubs along the latch side middle: Jamb may be pinched or twisted, paint buildup, or the door has swollen.
• Rubs at the bottom latch-side corner: Door is out of square, floor is higher (new rug, new flooring), or the jamb settled.
• Hard to latch but not rubbing much: Strike plate alignment issue, latch not centered, or the door is slightly racked.
• Seasonal sticking (worse in summer): Humidity swell in the door or jamb, especially if the top or bottom edge is unsealed.

Fix 1: Tighten hinges (the first thing I do)

Loose hinges are the number one culprit. When a hinge leaf shifts even a hair, the top of the door swings into the frame and rubs.

How to tighten the right way

• Open the door slightly so it is stable and not pulling on the screws.
• Tighten every screw on all hinges. Use a screwdriver for the final snug so you do not strip the head.
• If a screw just spins, remove it and stick a couple toothpicks (or a golf tee) with wood glue into the hole. Snap flush and reinstall the screw.

Upgrade move: replace one screw with a long screw

If the door is sagging, swap one screw in the top hinge jamb-side leaf for a 2-1/2 in to 3 in screw. That bites into the framing behind the jamb and pulls everything back into line.

• Use a screw that fits the hinge hole countersink so the hinge closes flat.
• Tighten slowly. Watch the reveal at the top latch corner as you snug it.

When tightening is not enough

If the hinge barrels have obvious play, the pin is bent, or a hinge leaf looks warped, tightening will not fix it. At that point, replacing the hinge (or all hinges so they match) is usually the clean move.

Fix 2: Shim the hinge (move the door a hair)

If your hinges are tight but the door still rubs, you may need a tiny geometry change. A paper-thin shim at a hinge can move the latch side more than you would expect.

Simple decision rules

• Top latch corner rub (classic sag look): Start with Fix 1 and the long screw in the top hinge. If it still kisses the frame, a thin shim behind the bottom hinge (jamb-side leaf) can help rotate the door so the top latch corner pulls away.
• Bottom latch corner rub: A thin shim behind the top hinge can sometimes lift the latch side slightly and change the swing path. Also check floor clearance before you do anything else.
• Hinge side rubs: Often it is paint buildup, a hinge not seated flat, or a mortise issue. Clean first, then consider seating the hinge properly (below).

How to shim a hinge (quick and clean)

• Close the door and mark the rub area with pencil so you can re-check after.
• Open the door, support it, and remove the screws from one hinge leaf (usually jamb-side).
• Cut a shim the shape of the hinge leaf. Cardstock, a playing card, or purpose-made hinge shims work great.
• Reinstall the hinge with the shim behind it and test the swing.

Start with one thin layer. If you go too thick, you can create a new rub somewhere else. Doors are funny like that.

If the hinge is not sitting flush

If the hinge is held out by paint or a shallow mortise, shimming is the wrong direction. Scrape paint off the hinge and mortise first. If the mortise is truly too shallow, you can carefully deepen it with a sharp chisel. Go slow and stay flat so the hinge leaf sits fully seated. If that sentence made your stomach tighten, stick to tightening and shimming and call in help for mortise work.

Fix 3: Adjust the strike plate (if it closes but will not latch)

Sometimes the door swings fine, but you have to lift, shove, or slam to get the latch to click. That is usually strike plate alignment, not a rubbing issue.

Quick diagnosis

• Close the door slowly and watch where the latch hits the strike plate opening.
• Look for fresh metal scratches on the strike plate.

Two simple fixes

• Tighten the strike plate screws. Loose plates drift.
• Reposition the plate slightly. Remove it, fill the old holes with toothpicks and glue, then re-screw in the correct spot. You can lightly file the opening in a pinch, but moving it is the cleaner solution.

Fix 4: Plane or sand the door (when the house is right and the door is not)

If hinges are solid and the jamb looks reasonably straight, but the door is still rubbing, you likely need to remove a small amount of material from the door edge. This is common with humidity swell or after new paint.

How much to remove?

Usually: a little. Think 1/32 in to 1/16 in. If you are taking off more than that, stop and re-check the root cause. Something else might be shifting.

Before you plane wood, remove paint ridges

If the door was recently painted, the “rub” might be thick paint on the edge or stop molding. Scrape or sand the paint buildup first. It is faster than planing and keeps you from changing the door fit unnecessarily.

Step-by-step planing (my go-to method)

• Mark the rub area clearly with pencil.
• If you are unsure, take the door off. Light touch-ups can be done on the hinges, but it is easier to control a plane with the door on sawhorses.
• Use a sharp block plane and take light passes with the grain.
• Test fit often. I like to plane a few strokes, hang or close the door, then check again.
• After it clears, sand the planed area (120 then 180) to remove sharp edges.
• Seal the fresh wood. Paint or clear coat the edge so it does not swell again as easily.

Note on hollow-core doors

Many interior doors are hollow-core with a thin skin. You can plane a small amount, but do not get greedy. If you remove too much on the latch edge, top, or bottom, you can expose the hollow area or weaken the edge. If you need major material removal, re-check hinges and jamb alignment first, and consider a pro if the opening is badly out of whack.

What if you do not have a plane?

You can sand, but it is slower and easier to make a wavy edge. If you sand, use a sanding block and keep the edge square. Avoid rounding over the corner too much or the door will look “melted.”

Fix 5: Shim the jamb (when the frame is the problem)

If your jamb is twisted or pinched, the door can rub even when it is perfectly hung. This is more common in older homes or after foundation settling, but it can happen anywhere.

How to check the jamb quickly

• With the door open, put a level against the hinge-side jamb and the latch-side jamb.
• Look for spots where the stop molding is tight against the door slab and other spots where there is daylight.

Simple jamb tweak (no full re-hang)

If the jamb is pinched near a hinge, you can sometimes correct it by adjusting the shims behind the jamb at that hinge location, but that usually means pulling casing. If that sounds like a whole Saturday, you are not imagining it.

For most homeowners, I recommend trying hinge, strike, and light planing fixes first. If you have to force the door into a visibly crooked opening, that is when jamb work makes sense.

Quick troubleshooting table

Finishing touches (so it stays fixed)

• Seal any fresh wood. Especially the top and bottom edges of the door. Unsealed edges drink humidity like a sponge.
• Lubricate hinge pins lightly. A tiny bit of silicone spray on a rag, wiped on the pin, keeps squeaks down. Avoid soaking painted surfaces.
• Do a final reveal check. You want an even gap on the sides and top, and enough clearance at the bottom for rugs and seasonal movement.

FAQ

Why does my door stick only in summer?

Humidity causes wood to expand. If the door edge or top is unsealed or the home is more humid in summer, the slab swells and the gap disappears. A light plane and sealing the edge usually solves it.

Can I just sand the sticking spot?

Yes, if it is minor and you use a sanding block. For anything more than a tiny touch-up, a sharp plane is faster and leaves a straighter edge.

How do I know if I should plane the door or fix the hinges?

If the rub is at the top latch corner, assume hinge sag first. If the door is tight along a long section of the latch side or it changes with weather, planing is more likely. If you see hinge play, bent hardware, or stripped screws, fix that first.

Is it normal for doors to go out of alignment over time?

Totally normal. Settling, seasonal movement, and simple screw loosening all add up. The goal is not perfection forever. It is a door that closes smoothly without needing a pep talk.
