Fence Gate Sagging? 5 Fixes Before You Replace the Whole Gate
Why gates sag (especially in New Orleans)
Most sagging gates aren’t “bad wood”—they’re bad alignment + weak hardware + post movement. In New Orleans, wet soil, humidity, and storm winds accelerate it. The good news: many gates can be fixed without replacement.
Quick diagnosis (30 seconds)
Dragging at the latch side bottom? Classic sag.
Latch won’t catch unless you lift the gate? Alignment is off.
Hinges loose or pulling out? Hardware failure.
Post leaning? That’s the real root cause.
5 fixes to try before replacement
1) Tighten/upgrade hinges and fasteners
If the hinge screws are stripped or too short, the gate will drift.
Replace with longer exterior screws into solid framing (not just pickets).
Upgrade to heavy-duty strap hinges for wider/heavier gates.
Best for: gates that sag but the post is still solid.
2) Add a gate anti-sag kit (cable + turnbuckle)
A diagonal cable supports the gate frame so it doesn’t “rack” out of square.
Install cable from top hinge corner to bottom latch corner (most cases).
Tighten turnbuckle until the gate lifts back into alignment.
Best for: wooden gates that are square-ish but drooping.
3) Re-square the frame with a diagonal brace
If the gate frame has twisted, a brace is stronger than cable.
Add a diagonal brace that pushes weight into the hinge side.
Replace cracked rails and re-fasten the frame properly.
Best for: older gates, warped frames, or gates that flex when pushed.
4) Reset the latch and strike plate (alignment fix)
Sometimes the gate is fine—the latch hardware isn’t.
Raise/lower the latch and strike to meet cleanly.
Add a stop block so the gate closes to the same point every time.
Best for: “it closes but won’t latch” problems.
5) Stabilize or reset the gate post (the real fix)
If the post is leaning or loose, every other fix is temporary.
Re-pack and set the post plumb.
Repair rot at the base or replace the post if it’s soft.
Best for: gates that keep re-sagging after “quick fixes.”
When replacement is the better move
Replace the gate when:
The gate frame is rotten/soft in multiple areas
The post is compromised and repairs would exceed replacement value
The opening is out of square and needs a full reset
