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
