How to Fix a Fence Gate That Won't Close

A gate that won't close is usually caused by sagging hinges, warped wood, or misaligned latches that can be fixed by adjusting hardware, planing wood, or repositioning strike plates.

1. Spot the Sag First. Look at your gate from the side to see if it's dropped lower than when first installed. Sagging happens when hinge screws loosen or when hinges wear out. If the gate hangs crooked or the bottom corner drags on the ground, your hinges need attention. Lift the gate slightly - if this makes it align with the latch, sagging is your problem.
2. Secure Every Screw. Remove any loose screws from the hinges and examine the screw holes. If holes are stripped and screws won't hold, pack them with wooden toothpicks or dowels dipped in wood glue, then trim flush once dry. Replace screws with slightly longer ones if possible, ensuring they bite into solid wood. Use a drill with a screwdriver bit to avoid over-tightening.
3. Swap Bad Hinges Out. If hinges are bent, cracked, or severely worn, replace them entirely. Choose heavy-duty hinges rated for your gate's weight - most residential gates need hinges rated for at least 150 pounds. Mark new screw holes carefully, drill pilot holes to prevent splitting, and use galvanized or stainless steel screws to prevent rust.
4. Feel Out the Warp. Run your hand along the gate's closing edge to feel for warping or swelling that prevents proper closure. Wood gates often swell in humid weather or warp from sun exposure. Mark any high spots with a pencil where the gate contacts the frame or latch post.
5. Shave Down High Spots. Use a hand plane or electric sander to remove material from marked high spots. Work gradually, testing the gate's closure frequently. Remove only small amounts at a time - you can always take off more material, but you can't put it back. Focus on the areas that actually contact the frame during closing.
6. Align the Catch Point. Check if the latch aligns properly with its strike plate or catch. The latch should slide smoothly into position without forcing. If misaligned, loosen the screws holding the latch or strike plate and reposition as needed. Sometimes moving the strike plate up, down, or in or out just a quarter-inch solves the problem completely.
7. Oil Every Moving Part. Apply a few drops of 3-in-1 oil or white lithium grease to hinge pins and latch mechanisms. Work the gate back and forth several times to distribute the lubricant. Avoid heavy oils that attract dirt and debris. Clean off any excess lubricant with a rag.
8. Verify Smooth Operation. Open and close the gate several times to ensure smooth operation. The gate should close easily without binding, dragging, or requiring excessive force. The latch should engage securely without rattling. Make small adjustments as needed until the gate operates like new.
