Sagging Gate: Why New Hinges Usually Do Not Fix It
It is the most common misdiagnosis in this trade. The gate drops, so the hinges must be worn. Occasionally that is true. Usually it is not.
What is actually happening
A gate hangs off one post. Everything the leaf weighs, plus the leverage of it swinging, goes into that post and the ground holding it.
When the post tilts even slightly, the far edge of the gate drops noticeably. The hinges may be perfectly serviceable.
How to tell the difference in a minute
Open the gate to ninety degrees and look at the post from the side. If it is out of plumb, that is your answer.
Then grip the post and push. Movement at the base, or a visible gap opening in the soil around it, confirms it.
Why the shortcut fails
Fitting new hinges to a leaning post gets the gate latching again for a few weeks. Then it drops back, because nothing that caused the problem was addressed.
We see gates in Van Nuys on their third set of hinges where nobody has looked at the post.
The proper repair
Break out the old footing, reset the post deeper and wider in fresh concrete, let it cure, then re-hang the leaf square and adjust the latch.
It costs more than a hinge swap and it is the last time you will think about that gate.
When it genuinely is the hardware
Heavy gates on undersized hinges do wear their pins oval, and cheap electroplated hinges rust and seize.
If the post is plumb and solid and the gate still drops, then the hardware is the job, and it gets replaced with something rated for the actual weight.
