Residential Fencing South Lyon MI | Call DeBord Fence

South Lyon's heavy clay soil expands significantly when wet and contracts as it dries. Over time, this repeated freeze-thaw cycle loosens the soil around standard-sized post holes. Without proper drainage or deep enough footings, the shifting soil pushes the post out of alignment, causing the entire fence section to lean.

Look for visible gaps between the post and the ground, especially after a heavy rain or spring thaw. If your gate no longer latches smoothly, or if you notice a bow in the fence line, the post likely moved. A telltale sign is water pooling around the base of the post—this indicates poor drainage and ongoing soil movement.

We dig post holes below the frost line—typically 42 to 48 inches deep—and use a wider diameter to accommodate drainage gravel at the bottom. This gravel layer wicks moisture away from the post and prevents the clay from heaving upward during freeze-thaw cycles. We also use pressure-treated lumber or galvanized steel posts for extra stability.
