What’s Happening

A gate that sags or drags on the ground almost always means one or more hinges have failed, shifted, or pulled away from the post they’re anchored to. The gate itself is usually fine – the problem is the connection between the gate and the structure holding it up. Left alone, it gets worse, not better.

Hinges carry the full weight of a gate every single time it moves. A standard residential driveway gate can weigh anywhere from 80 to several hundred pounds depending on the material. When a hinge starts to give – whether from metal fatigue, a stripped weld, loose mounting hardware, or a post that’s shifted in the ground – that weight redistributes onto the remaining hardware. The other hinges now carry more than they were designed for. The drag you’re seeing isn’t just cosmetic; it’s your gate telling you the load path is broken. The longer it runs that way, the more damage spreads to the gate frame, the motor arm (if you have an automated gate), and the post itself.

Why It Happens

Hinge pin and barrel wear

The pin inside a hinge barrel wears down over years of use, especially on a heavy gate that opens and closes multiple times a day. When the pin thins out enough, the gate loses its vertical position and starts to hang low on the latch side. You’ll usually see this as a gradual lean – the gate tilts and one corner begins scuffing the ground only at the fully open or fully closed position, not throughout the swing. Run your hand along the hinge while someone slowly moves the gate; if you feel the barrel rocking side to side, the pin or barrel is worn out.

Fastener pull-out from the post

This is the most common cause we see on wood and hollow steel posts. The lag screws or through-bolts holding the hinge plate to the post work loose over time, especially in climates with significant freeze-thaw cycling or heavy rain that softens the surrounding soil. When they pull out even slightly, the hinge plate tilts and the gate drops. Look at the hinge plate where it meets the post: if there’s a visible gap, paint cracking around the fastener holes, or the plate flexes when you push on it, the fasteners have let go.

Weld failure at the hinge or gate frame

On iron, aluminum, or steel gates, the hinge is typically welded to the gate frame. That weld can crack from repeated stress, impact (a vehicle clipping the gate, for example), or poor original workmanship. A cracked weld is usually visible as a rust line or gap running along the base of the hinge. If the hinge plate itself is solid but the entire corner of the gate has started to deform or twist, the frame weld – or the frame itself – is the problem, not just the hinge hardware.

Post movement or lean

If the post the gate is hung from has shifted – due to frost heave, soil erosion, a vehicle strike, or inadequate footer depth when it was first set – the geometry of the whole gate changes. The gate was hung plumb; the post no longer is. You’ll recognize this cause because the drag is consistent all the way through the gate’s swing, not just at one point, and the gap between the gate and the post or ground will be uneven top to bottom. Push gently on the post at shoulder height: if it moves at all, the footer below it has failed.

What to Do Right Now

• Stop running the gate through a motor if you have one. An automated operator pushing or pulling a gate that’s dragging on the ground puts serious strain on the motor arm, the drive gear, and the motor itself. Disconnect or disable the operator and move the gate manually until a technician arrives.
• Photograph the hinge from both sides before you touch anything. Get a close shot of the hinge plate where it meets the post, and a wider shot showing where the gate contacts the ground. This gives the technician a baseline and helps if there’s an insurance or HOA conversation later.
• Check whether the post rocks. Put your hands on the post and push steadily in multiple directions. If it moves, note it – that’s important information for the technician and it means the scope of the job may be larger than just the hinge.
• Do not attempt to re-weld a hinge or re-drive fasteners yourself if the post has moved. Re-attaching hardware to a shifted post just recreates the wrong geometry. The post has to be addressed before the hinge is reset, or the hinge will fail again quickly.
• Prop the gate only if you need to keep it stationary and safe. If the gate is partially open and a safety risk, brace it with a solid block or wedge to keep it from swinging. Don’t lean it on a vehicle. Don’t leave it unsecured if children or pets are around.

How We Fix It

When your local Carver Gate Repair team arrives, the first thing the technician does is a load assessment: the gate weight, the hinge type, the post condition, and what the anchoring substrate is. That takes a few minutes and it determines the actual repair path, because a hinge swap on a solid concrete-filled steel post is a different job than a hinge re-anchor on a wood post that’s rotted at the collar.

From there, the technician gives you a written price before any work starts. That number doesn’t move. If the diagnosis turns up something additional – a cracked weld, a compromised post footer – you’re told about it and given the updated written price. You decide whether to proceed.

The actual repair typically involves removing the failed hinge, cleaning and prepping the mounting surface, installing new hardware sized correctly for the gate’s weight, and re-setting the gate to plumb. If a weld has cracked, a mobile weld repair handles it on site in most cases. Post work takes longer and may require a follow-up once concrete sets. The gate repair service covers hinge replacement and frame work; gate motor repair covers reconnecting and re-calibrating the operator once the gate moves correctly again. Most hinge jobs are done in a few hours. Post replacement sets up in a day and cures over 24 to 48 hours before the gate is rehung.

Every repair is backed by the 365-Day Done Right Promise in writing. If it fails inside that year, we come back and make it right at no charge.
