Best Residential Fencing in New Castle, CO 81647 - Alpine Landscape and Construction

The primary cause is freeze-thaw cycles. During winter, moisture in the soil freezes and expands, which pushes fence posts upward or sideways. As the ground thaws in spring, the posts often settle unevenly, leading to leaning or loose fences. Heavy spring runoff from the nearby Flat Tops can also saturate the soil, further destabilizing posts that aren't set deep enough or with proper drainage.

Common signs include low water pressure at sprinkler heads, visible water pooling in one area of the yard, or sections of pipe that are suddenly exposed above ground. You might also notice sprinkler heads that no longer pop up fully or spray in the wrong direction. If you see these signs in early spring, it’s a strong indicator that frost heave has shifted or cracked your underground lines.

Alpine recommends setting fence posts below the frost line—typically at least 36 inches deep in New Castle—and using a gravel base for drainage. For areas with heavy runoff, they can install concrete footings with post anchors or use adjustable steel brackets that allow minor ground movement without causing the fence to lean. These techniques prevent the recurring damage that standard shallow-set posts often suffer.
