How to fix a sagging gate
Dragging or won't latch? The anti-sag brace, hinges, and post — in order.
By The T.A.P. Team · September 2024 · 5 min read
A gate that drags on the ground or won't line up to latch is almost always sagging at the far corner — pulled down by gravity and its own weight over time. The fixes, from easiest to hardest: tighten the hinges, add an anti-sag cable-and-turnbuckle brace to pull the corner back up, or, if the hinge post itself is leaning, reset the post. Here's how to work through it.
- 1Tighten or replace loose/worn hinge screws.
- 2Check whether the hinge post is leaning.
- 3Install an anti-sag kit (cable + turnbuckle) corner-to-corner.
- 4Tighten the turnbuckle to lift the latch corner.
- 5Reset the hinge post if it's the real problem.
Start with the hinges
A gate's weight works hinge screws loose over time, letting the gate drop. Tighten every hinge screw; if the holes are stripped, move to longer screws or fill and re-drill. Sometimes snugging the hinges alone lifts the gate enough to latch again. It's the five-minute first step before anything more involved.
Check the hinge post
If the hinges are tight but the gate still sags, look at the hinge post (the one the gate hangs from). A heavy gate can pull that post out of plumb, or our clay soil can heave it. If the post is leaning, no amount of gate bracing fully fixes it — the post has to be reset or replaced first, like any leaning fence post.
Install an anti-sag brace
The classic fix for a sagging gate frame is an anti-sag kit: a steel cable running diagonally from the top hinge-side corner to the bottom latch-side corner, with a turnbuckle you tighten to pull the drooping corner back up. Get the diagonal direction right (it must run from the top of the hinge side down to the bottom of the latch side) and tighten until the gate squares up and latches.
Prevent future sag
Heavy gates sag fastest, so a diagonal brace built into the frame from the start, quality hinges sized for the weight, and a solid, plumb hinge post prevent it. A gate wheel or a drop rod can also take load off a wide, heavy gate. If a gate keeps sagging despite all this, the frame itself may be racking and worth rebuilding — see how deep posts should be.
| Symptom | Likely cause | What to do |
|---|---|---|
| Gate drags, hinges loose | Loose hinge screws | Tighten or replace screws |
| Sags after tightening hinges | Hinge post leaning | Reset the hinge post |
| Latch corner drooping | Racked/heavy gate frame | Anti-sag cable + turnbuckle |
| Wide gate sags | Too much weight/span | Add brace, wheel, or drop rod |
| Keeps sagging | Frame racking / worn | Rebuild the gate |

An anti-sag turnbuckle brace works wonders on a racked gate frame — but only if the hinge post is solid and plumb. If the post is leaning, bracing the gate just fights a losing battle. Best practice is to confirm the post first, reset it if needed, then square the gate with the brace. Diagnose in that order and the gate latches — and stays that way.

The short version
- A sagging gate drags or won't latch because the far corner has dropped.
- Start by tightening the hinge screws — sometimes that's all it needs.
- Check the hinge post: if it's leaning, reset it before bracing the gate.
- An anti-sag cable-and-turnbuckle kit pulls the drooping corner back up.
- Run the cable from the top hinge corner down to the bottom latch corner.
- Heavy, wide gates sag fastest — build in a brace and use quality hinges.
