Fix a Cabinet Door That Won't Stay Closed

Cabinet doors that won't stay closed are annoying and they're a sign something has shifted. Whether it's a swollen door from humidity, hinges that have loosened from years of opening and closing, or mounting hardware that's come adrift, the fix is almost always straightforward. The good news is you don't need to replace the door or call anyone—most of these problems live in the hinges themselves. This guide walks you through diagnosing which problem you have and fixing it with basic tools and a methodical approach.

1. Read the gap like a problem statement. Close the cabinet door gently and look at the seam between the door and the frame. The gap should be even top to bottom and left to right. If the door touches the frame at the top but gaps at the bottom, the door is sagging. If it only touches on one side, the hinges have shifted sideways. If the entire door sits away from the frame, the hinges have backed out. Take a moment to understand exactly where the contact point is—this tells you what's happening.
2. Tighten every hinge screw. Open the cabinet door fully. Locate each hinge on the door's edge—most cabinet doors have two or three hinges. With a screwdriver that fits the screw head snugly, tighten every screw you see. Don't muscle them; turn them hand-tight plus one quarter turn. Check the top hinge first, then the middle (if there is one), then the bottom. This simple step solves the problem in most cases because hinges loosen from vibration and repeated use.
3. Test the result. Close the door slowly and feel for resistance. Look at the gaps again. If they're now even and the door closes with a consistent soft stop, you're done. If the problem persists, move to the next step. If the door now closes but the gap is uneven (tight at one end, loose at the other), you need to adjust the hinge mounting.
4. Find your adjustment points. Look at the hinge mounting plate on the cabinet body. European-style hinges (the most common in newer cabinets) have two or three small holes in the mounting plate. One hole is for mounting, but the other holes are for adjustment. The hole at the edge of the hinge (parallel to the door edge) adjusts side-to-side movement. The hole toward the cabinet's interior adjusts depth (how far the door sits from the face frame). Some hinges have both adjustments; some have one.
5. Shift the door left or right. If the door is tight on one side and gapped on the other, you need to move the hinge sideways. Loosen (but don't remove) the screw that mounts the hinge to the cabinet body. Locate the adjustment hole that runs along the edge of the door. Insert a Phillips screwdriver or hex key into this hole and turn it clockwise to move the door away from the frame, or counterclockwise to move it toward the frame. Make small adjustments—a quarter turn moves the door about 1/16 inch. Tighten the mounting screw again and close the door to check the gap.
6. Move the door forward or back. If the entire door sits too far out from the cabinet face (or sinks too close), the depth adjustment is what you need. This is the screw that runs perpendicular to the door edge, toward the inside of the cabinet. Loosen the main hinge mounting screw again. Insert your screwdriver or hex key into the depth adjustment hole. Turn clockwise to pull the door toward the cabinet body (into the frame), or counterclockwise to push it out. Make quarter-turn adjustments, tighten the mounting screw, and test the close.
7. Spot warping with a straightedge. If the hinges are tight and adjusted but the door still won't close evenly, the door itself may have warped or absorbed moisture. Look at the door edge-on from the side—sight along the length of the door to see if it bows outward. Place a straightedge against the back of the door in the middle and along the edges. If there's a gap under the straightedge, the door is not flat. A slightly warped door can sometimes be corrected by adjusting hinge depth to tilt the door back into plane, but significant warping means replacement.
8. Fine-tune with a shim. If you've adjusted the hinge and the door is close but not perfect, you can add a thin shim behind the hinge mounting plate. Remove the mounting screw that holds the hinge to the cabinet. Slip a thin piece of metal or plastic shim (available in hardware stores, or use a small piece of thin wood) behind the hinge plate. Reinstall the screw. This moves the entire hinge outward or inward slightly and is useful when hinge adjustment screws have reached their limit. Use a shim no thicker than 1/16 inch to avoid overcorrecting.
9. Rule out cabinet racking. Stand back and look at the entire cabinet unit. If the frame itself has twisted (one corner is further forward than the others), no hinge adjustment will fix a single door permanently. Check by looking at the cabinet from the side and also from above. If the box is out of square, the door problem is a symptom of a bigger issue. Stabilize the cabinet by securing it to the wall with L-brackets, or add diagonal cross-bracing inside the cabinet if it's a standalone unit. A racked cabinet will cause door problems across all doors.
10. Fix stripped mounting holes. If a mounting screw spins freely and won't tighten, the hole is stripped. Remove the stripped screw completely. Fill the hole with a wooden toothpick or wooden dowel coated in wood glue. Let it dry, then trim it flush with a utility knife. Drill a new pilot hole in the same location and install a new screw of the same size. If the hole is repeatedly stripped, use a slightly larger diameter screw, or move the hinge mounting up or down one inch and drill fresh holes.
11. Soften the door swing. If the door now closes properly but swings shut too fast or slams, consider adding a soft-close damper or adjusting the existing one. Many newer hinges have built-in soft-close mechanisms with adjustment screws. Look for a small screw on the side of the hinge near the joint. Turning this screw clockwise increases the closing resistance. If your hinges don't have this, you can add adhesive-mounted dampers to the inside of the cabinet frame—these slow the door's swing mechanically. Follow the manufacturer's instructions for installation.
12. Verify smooth closure. Close the door slowly ten times and listen for any creaks or grinding sounds, which indicate ongoing looseness. The door should close with a soft, even resistance and seat firmly without gaps. Look at the gap from the front and the side—it should be consistent. If you see any remaining unevenness, make one more small adjustment to the hinge that controls that area. Once the door closes cleanly and stays closed without drifting open, the repair is complete.
