Deflection / Sagging

Fence panel sag is typically caused by posts spaced too far apart for the rail and board dimensions, undersized rails, rotted or broken mid-rails in a wood fence, or loss of tension in a chain link fence. Thrive diagnoses root causes during repair assessments rather than applying cosmetic patches.

A gate drooping at the latch end has a hinge post that is out of plumb — leaning away from the gate, which gives gravity a mechanical advantage that pulls the latch end down. This is almost always a post problem, not a hardware problem. Re-plumbing and re-setting the hinge post corrects the issue permanently.

The fix depends on what is sagging. For a wood fence with a rotted mid-rail, replacing just the mid-rail and re-securing the boards often restores the fence. For chain link with stretched or failed fabric, replacing the fabric section between affected posts is sufficient. For post-related sag, the post must be re-set.
