Gates get more wear than the rest of the fence. They swing, slam, and support their own weight. Most gate problems are fixable without replacing the whole gate. Use our fence cost calculator if you are adding or replacing a gate.
Why Gates Fail More Than Fence Panels
Gates are freestanding. They hang from hinges and bear their full weight on a few attachment points. Wind, kids, and daily use add stress. Posts can shift. Hinges loosen. Latches wear out. Wood gates can sag as they absorb moisture. Metal gates can rust. Knowing these causes helps you fix problems quickly and prevent repeat failures.
Common Gate Problems and Fixes
| Problem | Common Cause | Fix |
|---|---|---|
| Sagging | Weak hinges, no diagonal brace, heavy gate | Add brace, upgrade hinges, adjust |
| Gate drags on ground | Sagging, sinking post | Lift gate, fix post, add wheel |
| Won't latch | Misalignment, worn latch | Adjust strike plate, replace latch |
| Sticks or rubs | Swollen wood, shifted post | Sand, plane, or adjust post |
| Hinges loose | Wood pulled out, rusted screws | Replace with longer screws, fill holes |
| Gate swings open | Slope, no latch | Install latch, add self-closing hinge |
Fixing a Sagging Gate
Sag is the most common gate problem. A diagonal brace helps. The brace should run from the bottom hinge side to the top latch side. For wood gates, use a 1x4 or 2x4 cut to fit and screwed firmly into the frame. For heavier gates, use a turnbuckle and cable: attach one end near the top hinge corner and the other near the bottom latch corner. Tighten the turnbuckle until the gate is level. Check that the hinges are tight. Loose hinges let the gate droop. Replace with longer screws or use through-bolts if the wood is pulling out. See fence post repair if the hinge post is leaning.
Gate Won't Latch
If the gate does not close squarely, the latch will not line up. First, fix any sag (see above). Then check the strike plate. It may need to move up, down, or in/out. Loosen the screws, shift the plate to match the latch, and retighten. If the latch is worn or broken, replace it. Magnetic latches hold better on gates that do not close perfectly.
Sticking or Rubbing
Wood gates can swell in humidity and rub against the post or latch post. Sand or plane the rubbing edge. For vinyl and metal, check if the post has shifted. If the hinge post is leaning, the gate will bind. Straighten or replace the post. See when to replace vs repair for post replacement guidance.
Hinge Upgrades
Cheap hinges bend and wear out. Heavier gates need heavy-duty hinges. Use three hinges for gates over 4 feet wide. Ensure screws are long enough to bite into solid wood—at least 2 inches. If screw holes are stripped, fill with wood filler or glue in a dowel, then re-drill. For gate posts, through-bolts provide the strongest hold.
Gate Wheel
For heavy gates that drag, a gate wheel can help. Mount it on the latch-side bottom corner. The wheel rolls on the ground and supports the gate weight. Choose a wheel rated for the gate weight and your surface (concrete, gravel, grass).
When to Replace the Gate
If the frame is rotted, warped beyond repair, or the gate is too damaged to fix, replacement is the answer. Use our fence cost calculator to estimate a new gate. Gates typically cost $200–$800 installed, depending on size and material. For installation tips, see fence gate installation.
FAQs
How do I fix a sagging gate?
Add a diagonal brace or a turnbuckle and cable. Tighten loose hinges. Ensure the hinge post is plumb. The brace should run from the bottom hinge corner to the top latch corner.
Why won't my gate latch?
Usually the gate is sagging or the strike plate is misaligned. Fix the sag first, then adjust the strike plate so the latch engages. Replace a worn latch if needed.
Can I repair a sagging gate without replacing it?
Often yes. Add a diagonal brace or turnbuckle, tighten hinges, and use longer screws if needed. If the frame is rotted or broken, replacement may be necessary.
How much does gate repair cost?
DIY repairs (brace, hinges, latch) typically cost $20–$100. Professional repair runs $75–$300. Gate replacement is $200–$800 or more depending on size and material.
