Fence Gate Dragging or Won't Close After Settling

A wooden gate that scrapes the ground or won't latch is sagging from loose hinges or a leaning post. Square it up before the gate destroys itself.

For Fence Gate Dragging or Won't Close After Settling, start with "Check if it's the hinges or the post": Open the gate halfway and look at the gap between the gate and the post on the latch side. If the gap is wider at the bottom than the top, the hinges are sagging. If the gap is wider at the top, the post is leaning. Use a 4-foot level on the hinge-side post — if the bubble is way off, the post has moved. This determines your whole approach: sagging hinges are a 15-minute fix, a leaning post is an afternoon project. Stop DIY if the post is rotted below ground level — if you dig down and the wood is soft, black, or crumbles in your hand, the post needs replacement. setting a new gate post requires digging out the old concrete and pouring a new footing, which may need a permit in some areas. This is listed as a moderate recovery and usually takes about 30-45 min.

help1. Understand the Problem

Wooden fence gates are heavy — a 6-foot gate weighs 40-60 pounds — and gravity never takes a day off. Every gate eventually sags. The weight pulls on the hinge side, the screws loosen or the wood around them compresses, and the latch side drops. Gravity also works on the post itself: the gate post leans outward over time as the soil compacts under the weight. The combination of sagging hinges and a leaning post means the gate corner drags on the ground, the latch no longer lines up, and if you ignore it long enough, the gate frame joints pull apart and the whole thing falls off.

Best First Step

Check if it's the hinges or the post

Open the gate halfway and look at the gap between the gate and the post on the latch side. If the gap is wider at the bottom than the top, the hinges are sagging. If the gap is wider at the top, the post is leaning. Use a 4-foot level on the hinge-side post — if the bubble is way off, the post has moved. This determines your whole approach: sagging hinges are a 15-minute fix, a leaning post is an afternoon project.

Tighten or replace loose hinge screwsIf the hinges are sagging but the post is plumb, start with the screws. Tighten every hinge screw on both the gate and the post. If a screw spins without tightening, the hole is stripped. Fix it: jam a wooden golf tee coated in exterior wood glue into the hole, let it dry, cut it flush, and drill a new pilot hole. Replace the original screws with longer ones if the originals are under 2 inches — sink them deeper into fresh wood. Use stainless or coated exterior screws; interior screws will rust in weeks.

Install an anti-sag gate kit if hinges are wornIf the hinges are tight but the gate still sags, the hinge pins themselves are worn. An anti-sag gate kit (also called a turnbuckle cable kit) costs $15-20. It's a stainless steel cable with a turnbuckle that runs diagonally from the top hinge corner to the bottom latch corner. Tightening the turnbuckle pulls the latch side up. Install it according to the kit directions — the cable must run from the top hinge (the fixed point) to the bottom latch (the sagging point). This is the permanent fix for wooden gates and will outlast the gate itself.

Straighten a leaning gate postIf the post is leaning, tightening hinges won't fix it. Dig down about 18 inches on the side of the post opposite the lean — expose the concrete footing. Plumb the post with a level and brace it with a 2x4 staked into the ground. Pack crushed gravel into the hole you dug, tamping it tight every few inches with a 2x4 or a tamper. The gravel locks the post in its new position. Then fill the top 4 inches with soil. If the post was set in concrete that's cracked, you may need to break out the old concrete and pour a new footing — a 60-pound bag of quick-set concrete is $5.

cut
Shorten the bottom of the gateIf the gate is solid and well-hung but just too long for the opening after settling, you can trim the bottom. Remove the gate, mark a straight cut line 1/2 to 1 inch above where it drags, and cut with a circular saw. Seal the raw edge with exterior paint or wood preservative before rehanging. Only do this if the gate is structurally sound and the cut won't compromise the bottom rail.

Replace the gate entirely if the frame is rottedIf the wood at the hinge points is soft, punky, or you can poke a screwdriver into it, the gate frame is rotting. Reinforcement hardware won't help — the wood can't hold screws anymore. Build or buy a new gate. Cedar and pressure-treated pine are the right materials. A pre-built cedar gate is $80-150 and comes with the frame already assembled.

Frequently Asked Questions

Why does my gate sag more in summer than winter?expand_more
Wood absorbs moisture in humid summer air and swells, which can actually tighten joints slightly — but soil also gets softer with rain, allowing the post to lean. Winter freeze-thaw cycles heave posts. The real answer is that weather cycles slowly work everything loose. An anti-sag cable kit works year-round regardless of weather.
Can I fix a sagging gate without removing it?expand_more
Yes. Install the anti-sag cable kit with the gate hanging. Tighten the turnbuckle incrementally and check the latch alignment as you go. The cable pulls the latch side up while the gate stays on its hinges. It's a 20-minute job with a drill and a wrench.
How deep should a gate post be set?expand_more
At minimum, one-third of the above-ground height. A 6-foot gate post should go at least 2 feet deep, preferably 2.5 feet. Below the frost line in cold climates — check your local code. Posts set too shallow will lean within the first year.
My gate latch won't line up — should I move the latch or fix the gate?expand_more
Fix the gate first. Moving the latch to match a sagging gate is treating the symptom, not the problem. After you've squared up the gate with an anti-sag kit or hinge repair, the latch will either line up again or you'll know it needs its own adjustment.

warning5. Stop DIY If

Don't continue if any of these apply.

reportThe post is rotted below ground level — if you dig down and the wood is soft, black, or crumbles in your hand, the post needs replacement. Setting a new gate post requires digging out the old concrete and pouring a new footing, which may need a permit in some areas.
reportThe gate is hanging from a masonry pillar that's cracked or loose — masonry repair is a different trade. If the pillar isn't solid, the gate can pull it down. Get a mason to assess it.
reportThe gate is part of a shared fence with a neighbor — check your property line and any agreements before removing or modifying the gate. Fence disputes get ugly fast.
