Fencing Company Fletcher NC | Call Fairview Fence

That's a sign of frost heave. Here in Fletcher, our clay soil holds moisture, and when it freezes, it expands and pushes shallow-set posts upward and out of plumb. It's a common local issue. At Fairview Fence, we solve this by setting posts at least 36 inches deep—below our area's frost line—and using a concrete collar that resists that upward pressure. This keeps your fence straight through freeze-thaw cycles.

That's usually soil saturation and slight ground movement after heavy rain. When the ground softens, posts can shift just a bit, throwing off a gate's alignment. It's especially common near low-lying spots off Hendersonville Road. Our fix is to install gate posts with a thicker concrete base and use adjustable gate hinges. That way, even if the ground moves, we can easily tweak the gate back to level without resetting the entire post.

Tree roots from common local species like oaks and pines can definitely push against fence panels over time. The best solution is to plan your fence line a few feet away from major trees. When that's not possible, we use root barriers during installation and opt for post-mount brackets that sit on top of the soil rather than deep-set posts that roots might shift. This keeps your fence stable without harming the tree.
