A door that won't close smoothly can be a daily irritation. Before you consider a full door replacement, it's worth understanding the common issues that prevent a door from functioning correctly. Often, the problem stems from one of three areas: the latch mechanism, moisture-related wood swelling, or hinge alignment.
Understanding Why Your Door Won't Close
Most door closing issues fall into a few predictable categories:
- Latch Alignment: The most common issue, where the latch bolt doesn't properly engage with the strike plate on the door frame.
- Swollen Wood: Often caused by humidity or moisture, the wood of the door or frame expands, causing it to rub against the frame.
- Hinge Adjustment: Loose or improperly set hinges can cause the door to sag or become misaligned within the frame.

Troubleshooting: Latch Alignment Issues
If your door isn't latching, or you have to forcefully push it to close, the strike plate is likely the problem.
How to Diagnose:
- Visual Inspection: Open the door and look at the strike plate on the door frame. Do you see any scrape marks around the opening where the latch bolt should enter? This indicates the latch is hitting above or below the opening.
- The Lipstick Test: Apply a small amount of lipstick or chalk to the tip of your door's latch bolt. Slowly close the door until the latch touches the strike plate. Open the door and check the strike plate for a mark, which will show you exactly where the latch is making contact.
How to Fix:
- Adjust the Strike Plate: If the latch is slightly off, loosen the screws on the strike plate. With the screws loose, you might be able to shift the plate slightly up or down, or in or out, to align it with the latch. Retighten the screws.
- Enlarge the Opening: For more significant misalignment, you may need to carefully enlarge the opening in the strike plate using a metal file, or a chisel if the wood underneath also needs adjusting. Go slowly and test frequently.

Troubleshooting: Swollen Wood (Moisture)
Wood doors and frames can absorb moisture from the air, especially in humid environments, causing them to expand and rub against each other.
How to Diagnose:
- Look for Rub Marks: Inspect the edges of the door and the inside of the door frame for scuff marks or areas where the paint or finish is worn down. These indicate where the door is rubbing.
- Feel for Resistance: Try to close the door. Does it feel tight or get stuck at a specific point? This suggests swelling.
- Consider the Season: Is it a particularly humid time of year? Changes in weather often correlate with wood swelling.
How to Fix:
- Identify Rubbing Spots: Use a piece of chalk or even a dollar bill. Place it where you suspect rubbing and close the door. The chalk will mark the high spots, or the bill will be difficult to pull out.
- Sand or Plane the Door: For minor rubbing, you can usually sand down the affected edge of the door using medium-grit sandpaper. For more significant swelling, you might need to remove the door and use a hand plane or power planer to shave off a thin layer of wood from the edge. Always work slowly and re-check the fit frequently.
- Reseal Exposed Wood: After sanding or planing, ensure you re-paint, re-varnish, or re-seal any exposed wood edges to prevent future moisture absorption.
Troubleshooting: Hinge Adjustment
Loose or bent hinges can cause a door to sag, making it rub against the frame or preventing the latch from aligning.
How to Diagnose:
- Check for Gaps: Open the door and observe the gap between the door and the frame. Is it consistent all the way around? A widening gap at the top or bottom often indicates a sagging door.
- Tighten Screws: Grab a screwdriver and try to tighten all the screws on each hinge, both on the door and the frame side. Sometimes, this alone is enough to resolve the issue.
How to Fix:
- Replace Stripped Screws: If a hinge screw just spins and doesn't tighten, the screw hole is stripped. Replace the screw with a longer one (e.g., 2.5 to 3 inches) that can reach into the door frame's studs for a firmer hold. Alternatively, you can insert a wooden dowel (with wood glue) into the stripped hole, let it dry, and then re-drill a pilot hole for the original screw.
- Bend the Hinge Pin: For a slight adjustment, you can carefully remove a hinge pin (usually the top one) and gently tap it with a hammer to slightly bend it. Reinserting a slightly bent pin can pull the door tighter into the frame on that side.
- Shim the Hinges: If the door still sags, you can place thin shims (made from cardboard or thin wood veneer) behind the hinge leaves on the door frame side. This effectively pushes the hinge out slightly, adjusting the door's position. Experiment with different hinges (top, middle, bottom) to see which adjustment works best.
