How to fix a door that sticks, squeaks, or won't latch

A door that sticks, squeaks, or won’t latch is annoying and sometimes genuinely frustrating. The good news is that most door problems are fixable with basic tools and a small amount of effort. Understanding what causes common problems helps you fix them, or at least understand when professional help is necessary.

Door Sticking and Binding

A sticking door is usually caused by one of several things.

Humidity swelling is the most common cause. In humid weather, wood absorbs moisture and swells. A door that fits fine in dry weather might bind in humid weather. In dry weather, the door might have gaps around it. This swelling and shrinking is normal and usually temporary.

A quick fix is a dehumidifier in the room. Reducing humidity allows the door to shrink back to normal size. Once humidity normalizes, the door usually functions normally again.

A permanent sticky door might be caused by hinges that are worn or misaligned. If the door frame has shifted, the door might not be perfectly vertical. This causes binding.

You can check door alignment by looking at the gaps between the door and the frame. The gaps should be consistent on all four sides. If the gaps are uneven (wider at the top on one side, narrower on the other side), the door is misaligned.

Minor misalignment can be corrected by adjusting hinges. The top hinge has a screw that allows adjustment. Loosening this screw slightly allows you to shimmy the door into a better position. Retightening the screw holds the door in the new position.

If the binding is severe, you might need to plane the door edge. This involves removing a thin layer of wood from the edge where the door binds. This is more complex and might be better handled by a professional if you’re uncomfortable with woodworking.

Squeaky Doors

A squeaky door is almost always caused by dry hinges. The solution is simple: lubrication.

Use a light oil or silicone spray lubricant. Spray or apply oil to the hinge pin and the hinge mechanism. Open and close the door a few times to distribute the lubricant. The squeak should disappear.

If lubrication doesn’t eliminate the squeak, the hinge might be worn. Worn hinges can sometimes be adjusted or replaced. If the door has multiple squeaky hinges, hinge replacement might be more practical than trying to fix each hinge individually.

Won’t Latch or Catch

A door that won’t latch is usually caused by misalignment between the door’s latch and the strike plate.

The strike plate is the piece on the door frame that receives the latch. If the strike plate is too high or too low, the latch passes above or below it without catching.

Check alignment by placing a piece of graphite (pencil mark) on the latch. Close the door gently. When you open it, the graphite will mark where the latch contacts the strike plate. If the mark is above or below the strike plate, the strike plate needs adjustment.

The strike plate can usually be adjusted by loosening the screws and shifting it up or down. Try moving it slightly in the direction needed to center the latch in the strike plate opening. Retighten the screws and test the door.

If the misalignment is severe, you might need to drill new screw holes in a different position. Mark the new position, drill holes, and install the strike plate screws in the new location. Fill the old screw holes with wood filler.

Loose or Rattling Handles

A loose handle usually has loose fastening screws. Tightening the screws usually solves the problem.

Interior handles typically have set screws under or beside the handle that tighten the handle onto the spindle (the metal shaft that connects the two sides of the handle).

Exterior handles typically have screws on the interior side of the door that connect the handle plates together.

Tighten these screws periodically as they loosen with use.

If tightening doesn’t solve the problem, the handle mechanism might be stripped or broken. In this case, handle replacement is necessary.

Gaps Around the Door

Gaps around the door frame allow drafts, noise, and pests to enter.

Gaps are usually caused by worn or missing weatherstripping. Weatherstripping is the foam, rubber, or metal seal around the door frame.

Inspect the weatherstripping. If it’s cracked, compressed, or missing, it needs replacement.

Weatherstripping is usually self-adhesive. Remove the old weatherstripping, clean the surface, and install new weatherstripping. It’s a simple, inexpensive fix.

Gaps at the bottom of the door are addressed with a door sweep. A door sweep is a strip that seals the gap between the door and the threshold.

Stuck Locks

A lock that’s stuck or difficult to turn might be dry inside.

Apply lock lubricant (a graphite-based spray, not oil) into the lock. Don’t use oil; it attracts dirt and makes the problem worse.

Spray a small amount into the lock and manipulate the key several times to work the lubricant into the mechanism.

If lubrication doesn’t help, the lock cylinder might be worn or broken. Lock cylinder replacement is necessary.

Water Damage or Rot

If a door has soft spots, visible rot, or water damage, it needs replacement. Water damage is progressive. A door with early rot will worsen over time. Replacement is more practical than repair.

When to Replace vs. Repair

For old doors with multiple problems, replacement might be more cost-effective than fixing each issue individually.

A new door costs $200 to $800 depending on type and quality. Repair costs vary based on the problem. If you’re spending $100 to $200 on repairs repeatedly, a new door might be a better investment.

New doors offer improvements like better insulation, improved security features, and modern aesthetics.

Prevention and Maintenance

Most door problems can be prevented through regular maintenance.

Lubricate hinges once or twice per year.

Check weatherstripping periodically and replace if needed.

Tighten loose fasteners before they become problems.

Keep humidity levels in your home consistent to minimize wood swelling and shrinking.

Address small problems before they become big ones.

The Reality

Most common door problems are fixable with basic tools and a small amount of effort. Lubricating hinges, adjusting strike plates, and replacing weatherstripping are all straightforward tasks. If you’re unsure about any repair, or if the problem persists after attempting a fix, consult a professional. A handyman or door specialist can diagnose and repair more complex problems. Most door problems don’t warrant professional help, but some do.
