Key takeaways
- Most sagging gates have a loose hinge, a cracked corner, a leaning post or no diagonal brace.
- A diagonal brace often fixes a sag for good.
- Rusted bottoms need new steel, not a patch.
- Heavy gates need properly sized posts and hinges.
The usual causes
A gate is a rectangle hanging from one side, and gravity tries to turn it into a parallelogram. Loose hinge bolts, worn hinge pins, a cracked weld at a corner and a post that has shifted or leaned all let the gate drop on the latch side.
Gates without a diagonal brace sag more easily, and heavy gates on light posts will pull the post over time.
Fixes that last
The cure starts with the cause. Tighten or replace hinges, re-weld cracked corners, add a diagonal brace running from the top hinge side to the bottom latch side and reset or reinforce the post if it leaned. Adjustable hinges can take up small amounts of sag.
If the bottom rail has rusted through, we cut out the damaged steel and weld in new, then prime and paint so rust does not return.
Prevent the next one
Keep hinges greased, touch up chipped paint and do not let the gate be used as a fence for leaning or hanging loads. If you are adding a gate operator, make sure the gate is straight and well braced first, because opening and closing stress a weak gate quickly.
For new gates, ask for frames braced properly and posts set deep enough for the weight.

Quick answers
Can I fix a sagging gate myself?
Simple hinge adjustments are often possible. Re-welding cracks or replacing rusted sections should be done by a welder for strength and safety.
How long does a gate repair take?
Many gate repairs take one to three hours on site. A full rebuild takes longer and may involve shop time.
