Best Residential Fencing in Edwardsville, IL 62025 - Greenscape Pools & Landscaping

Frost heave is the main culprit here in Edwardsville. When moisture in the soil freezes, it expands and pushes fence posts upward. You’ll notice signs like a post that looks taller than it used to be, gaps forming between the post and the ground, or a gate that no longer swings or latches correctly. If your fence rails appear to be pulling away from the posts, that’s another clear sign the ground has shifted.

Yes, in many cases we can. If the rails have pulled away from the posts because of frost heave, we assess whether the posts can be reset or if they need replacing. We’ll realign the posts, set them deep enough to stay stable, and then reattach the rails with sturdy hardware. It’s a targeted fix that saves you from tearing down a whole fence section.

The key is setting posts below the frost line—typically 36 to 42 inches deep in our area—and using concrete that extends above the soil to shed water away. We also choose materials like pressure-treated wood or steel posts that resist moisture damage. For existing fences, we can retrofit posts with gravel bases to improve drainage and reduce heave risk.
