# Gate sagging or won't latch: how to fix it

Updated: 2026-10-24 · https://pros411.com/en/guides/handyman/gate-sagging-wont-latch

## Short answer

Tighten the hinge screws first, using longer exterior screws where the holes are stripped. Then prop the latch side level on a block and install an anti-sag kit. Its cable runs from the top corner on the hinge side to the bottom corner on the latch side. Tighten the turnbuckle until the gate stays square, then adjust the latch. If the post leans, fix the post.

> Safety first: If it is a pool gate, fix it right away and keep children out of the pool area until it closes and latches on its own every time.

## How to fix a sagging gate

1. **The gate drags and misses the latch.** The latch side has dropped. Find what is loose: the hinge screws, the gate frame or the post itself.
2. **Tighten the hinge screws.** Drive every hinge screw tight. Stripped holes take longer exterior screws that bite into fresh wood in the post.
3. **Block it level, add a cable kit.** Prop the latch corner up on a block. Screw one plate at the top corner on the hinge side, the other low on the latch side, and hook up the cable.
4. **Tighten the turnbuckle.** Turn it until the cable is tight and the gate stays square without the block. Do not overtighten, or the gate bows.
5. **Swings free and latches.** Pull the block out and swing the gate. If the latch still misses, move the latch bar or the catch a little until it clicks.

## Check the post first

Push the hinge post with your hand. If it leans or rocks at the base, it is rotten or loose in the ground, and no hinge or cable will hold the gate up. The post has to be reset or replaced, usually in new concrete. That is a job for a handyman or a fence contractor.

## A wood brace instead of a cable

A diagonal wood brace does the same job. It runs from the bottom corner on the hinge side up to the top corner on the latch side, so it pushes the latch side up. A brace set the other way lets the gate keep sagging.

## What not to do

- Do not just move the latch lower. The gate keeps sagging and soon drags.
- Do not use indoor drywall screws outside. They rust and snap.
- Do not hang a heavy gate on light hinges. Use hinges sized for the gate.

## When to call a handyman

- The post leans or rocks at the base.
- The gate frame is rotten or split at the joints.
- It is a pool gate that will not close and latch by itself.
- It is a metal gate and a hinge or a weld has broken.

## Frequently asked questions

### Why is my gate sagging?

Usually loose hinge screws, a frame with no diagonal brace, or a leaning post. A gate is heavy and hangs from one side, so gravity slowly pulls the latch side down.

### Do anti-sag gate kits work?

Yes, when the post is solid. The cable and turnbuckle pull the latch side back up and keep the frame square. They do not fix a leaning or rotten post.

### Which way does a gate brace go?

From the bottom corner on the hinge side up to the top corner on the latch side. That way it pushes the latch side up. Set the other way, it does not stop the sag.

### How do I fix a gate that won't latch?

First fix the sag so the gate hangs level. Then move the latch bar or the catch until they line up. Wood swells in wet weather, so leave a little play.

### How do I fix a gate dragging on the ground?

Lift it back to level: tighten the hinges and add an anti-sag kit or a diagonal brace. If the ground has built up, dig out a little soil where the gate swings.

### Does a pool gate have to close by itself?

It should close and latch on its own, with the latch out of reach of small children. If yours does not, keep kids away from the pool until it is fixed.
