Stable Fence: Reliable Fencing Company Serving Milwaukee, WI 53216

The main cause is frost heave. In Milwaukee, the ground freezes and thaws repeatedly during late winter and spring. When moisture in the soil freezes, it expands and pushes against fence posts. If the posts aren't set deep enough—below the frost line—they can lift and tilt. This is especially common in neighborhoods like Riverwest or near the Menomonee River Valley where the soil has high clay content.

Look for signs like a gate that drags on the ground, won’t latch properly, or has visible gaps between the gate and the latch post. You might also see the gate sagging on its hinges. If you notice these issues after a thaw, it’s a strong sign the supporting posts have shifted. Catching it early can prevent damage to the gate or hinges.

The most effective solution is to reset the affected posts with concrete footings that extend below the frost line—typically 48 inches deep in our area. At Stable Fence, we also use galvanized brackets and heavy-duty hinges that can handle minor movement without failing. For gates, we recommend adding an anti-sag kit or upgrading to a self-closing hinge system. This keeps your fence functional through every season.
