You've tightened that gate latch three times this month. Maybe you replaced the hardware entirely. But here's the thing — two weeks later, the gate's sagging open again and you're back out there with a screwdriver. Sound familiar?

The problem isn't the latch. It's not even the hinges most of the time. If your gate won't stay closed no matter what you fix, you're treating symptoms while the real issue keeps getting worse. Working with a Fence Contractor Villa Rica GA who understands gate mechanics can save you from wasting money on parts that won't solve anything.

The Real Reason Gates Stop Latching

Gates fail because of movement — not the gate itself moving, but the posts it's attached to. Your fence posts shift over time from soil settling, weather cycles, and the repeated stress of opening and closing a gate. When posts move even half an inch, the gate frame goes out of square.

That misalignment means your latch no longer lines up with the catch plate. You can adjust it temporarily, but the posts keep moving and you're back where you started. The latch you bought isn't defective. The installation wasn't necessarily bad when it was new. Physics just caught up.

Three Structural Problems That Break Gates

Most homeowners don't check these until after they've spent money on new hardware. Here's what actually needs inspection before you buy another latch.

First — rotted or undersized posts. If your gate post is a standard 4x4 and you've got a six-foot double gate, that post is working too hard. Wood posts also rot from ground contact. A post that looks fine above ground might be crumbling below the soil line. Push hard on the post perpendicular to the fence line. If it moves more than a quarter inch, that post is compromised.

Second — undersized or worn-out hinges. A residential gate needs hinges rated for its actual weight, not what the packaging says fits a "standard gate." Wood gates get heavier as they age and absorb moisture. If you've got two small strap hinges holding up a solid wood gate, those hinges are bending under load. The gate sags, the latch misaligns, and no amount of adjustment fixes it because the hinges can't hold the gate level.

Third — a gate frame that's come apart at the joints. Most wood gates have diagonal bracing and corner joints held together with screws. Those joints loosen from vibration and stress. When the frame loses its rigidity, the whole gate twists slightly and your latch alignment goes out the window. Tightening the latch doesn't tighten the frame.

How to Tell If Your Posts Have Shifted

This is the test most people skip. Close your gate and look at the gap between the gate edge and the latch post. Is it even top to bottom? If the gap is wider at the top than the bottom, your latch post is leaning away from the gate. If it's wider at the bottom, the post is leaning in or the hinge post is leaning out.

Now check the hinge post. Stand parallel to the fence line and eyeball whether the post is plumb (straight up and down). If it's leaning even slightly toward the yard, your gate is sagging at the latch end because the hinge side dropped. A four-foot level against the post will confirm it.

If either post has moved, fixing the latch is pointless. The posts need to be reset or the gate needs to be rehung to account for the new post positions. And if the posts are rotted below grade, they need replacement before any other fix will hold.

When to Call a Fence Contractor Instead of DIY Fixing

You can replace a latch yourself if the posts are still plumb and solid. But if you've already replaced hardware twice and the problem keeps coming back, it's a structural issue. A Fence Contractor can pull a post, inspect it, and reset it properly with concrete. They'll also catch things like undersized hinges or frame joints that are about to fail.

Here's what they check that most homeowners don't — post depth (should be one-third the post height below grade), concrete condition around posts, hinge size relative to gate weight, and whether the gate frame itself is still square. If your New Georgia Fence Company crew is resetting a post, they're also checking adjacent posts for movement because if one shifted, others probably did too.

Why Surface Fixes Keep Failing

Every time you adjust that latch, you're compensating for a moving target. The posts keep shifting, the gate keeps sagging, and your adjustments get you a few more weeks of function before it fails again. Meanwhile, the real problem — rotted posts, bending hinges, or a frame that's lost rigidity — is progressing.

Eventually you'll hit a point where no adjustment works because the misalignment is too severe. Now you're facing a full gate replacement when you might've gotten away with a post reset six months ago. Fence and Gates Installation Villa Rica professionals see this pattern constantly — homeowners who spent $200 on latches and hardware when a $400 post repair would've solved it permanently.

What Actually Needs to Be Fixed

If your posts are plumb and solid, and your hinges are rated for the gate weight, then you've probably got a frame issue. The diagonal brace that keeps the gate square has either come loose or was never installed correctly. You can usually tell by lifting the latch end of the gate slightly — if it moves up more than half an inch before binding, the frame isn't rigid.

Fixing that means disassembling part of the gate, re-squaring the frame, and securing all joints properly. It's not a latch replacement job. It's a rebuild. And if you're going to rebuild the gate, it's worth having someone check the posts at the same time because post movement might be what stressed the frame joints in the first place.

Some gates just weren't built to last. If you've got a big wood gate on undersized posts with minimal bracing, it was always going to fail. A proper gate has a frame that's cross-braced, hinges sized for the weight, and posts sunk deep enough to resist the leverage forces. Fence Repair Services near me get calls all the time from homeowners who thought they were getting a good deal on a gate install, but the installer skimped on posts or hinges and now the whole thing's failing two years in.

The Cost of Waiting Too Long

A gate that won't latch is annoying. A gate that's visibly sagging is a safety issue — it can swing into people, drag on the ground and create a trip hazard, or fall off the hinges entirely if the posts give way. And if your gate is part of a pool enclosure or required for building code compliance, you're also looking at potential liability if it fails and someone gets hurt.

Catching post movement early means you can reset the posts without replacing them. Wait until the post is rotted through and you're replacing posts, concrete, hardware, and possibly the gate itself. The price difference between a post reset and a full gate replacement is usually 3-4 times.

Here's the reality — if you've adjusted that latch more than twice and it keeps failing, you're past the DIY fix stage. If you're looking for a Fence Contractor Villa Rica GA, get someone who'll inspect the posts and frame, not just slap new hardware on and hand you a bill. The right fix addresses why the gate moved in the first place, so you're not doing this again next year.

Frequently Asked Questions

How long should a gate latch last before needing replacement?

A properly installed latch on a structurally sound gate should last 5-10 years depending on usage and weather exposure. If you're replacing latches every year or two, the gate or posts have an underlying problem that hardware can't fix.

Can I fix a sagging gate without replacing the posts?

Sometimes. If the sag is minor and caused by loose frame joints or worn hinges, you can repair those without post work. But if the posts have shifted or rotted below grade, no amount of gate repair will hold — the posts need attention first.

How do I know if my gate posts are rotted underground?

Push hard on the post perpendicular to the fence. If it moves easily or feels spongy, there's rot. You can also dig down six inches next to the post and inspect the wood directly. Brown, soft wood that crumbles when you press it means rot has set in.

What size hinges do I need for a six-foot wood gate?

A solid wood gate that size typically weighs 80-120 pounds. You need hinges rated for at least 150 pounds total capacity to account for stress and aging. Most residential "gate hinge kits" are undersized for anything over four feet.

Why does my gate only sag in summer or winter?

Temperature and moisture cause wood to expand and contract, and soil to shift. A gate that works fine in spring might bind in summer heat or sag in winter cold because the posts or frame are moving slightly with seasonal changes. If it's happening every year, the posts likely aren't set deep enough or the soil around them is unstable.
