Commercial Fencing Aberdeen SD | Call Mohr's Fencing Supply

In Aberdeen, the primary cause is frost heave, which happens when moisture in the soil freezes and expands, pushing posts upward. This is common in areas with heavy clay soils, like neighborhoods near Richmond Lake or along the Moccasin Creek floodplain. At Mohr's Fencing Supply, we recommend using concrete collars and gravel drainage at the base of posts to minimize movement. We stock extra-long steel and treated wood posts designed to anchor below the frost line—about 48 inches deep in this region.

A sure sign is a gate that won't latch properly or gaps appearing between fence pickets after a thaw cycle. If you notice posts tilting unevenly or concrete footings popping up from the soil, it's likely frost heave. Simple wear usually shows as loose nails or rotting wood. Our team near the Aberdeen Mall helps customers differentiate—often just by looking at the post's alignment with the ground. We carry adjustable gate hinges and replacement brackets to fix sag issues quickly.

For long-term stability, we recommend our galvanized steel chain-link or heavy-duty vinyl fencing paired with frost-proof installation. These materials resist moisture damage and won't warp like wood. For homeowners in the Northern State University area who want a wood look, we supply pressure-treated pine with metal post sleeves. Mohr's Fencing Supply also offers specialized gate hinges with self-closing mechanisms that prevent warping. Stop by our store near the Brown County Courthouse—we can show you what works best for your lot.
