Sagging or dragging gate: causes and fixes
A gate sags when its hinges bend or rust, the hinge screws loosen or strip, the post moves, or the frame goes out of square. Signs are a latch end that scrapes the ground, a post that is not plumb, and diagonals that are not equal. On a motorized gate a sag also loads the operator. Angi puts professional repair at about $400. Source: Angi.
Likely causes
- Bent or rusted hinges.
- Loose or stripped hinge screws.
- A post that has moved.
- A frame out of square (Angi).
Signs to look for
- The latch end scrapes the ground.
- The post is not plumb.
- The two diagonals of the gate are not equal (Angi).
On a motorized gate, a sag makes the operator work harder. It can trigger force reversals (see gate reverses). With the power off and the operator released, check whether the gate moves freely by hand (Mighty Mule gate opener maintenance guide).
When to call a gate company
- The gate is motorized.
- The post has moved, or the frame is bent.
- Hinges need replacing or welding.
