Protection Fence Co-Div of Southeastern: Reliable Fence Contractors Serving Knoxville, TN 37915

Knoxville’s clay-heavy soil expands when wet and contracts during dry spells, especially with our freeze-thaw cycles. This soil movement can push fence posts out of alignment. At Protection Fence Co., we set our posts below the frost line and often add gravel or concrete collars to anchor them securely. This local approach prevents the leaning you see on many older fences in areas like Bearden or Fountain City.

Often it's both. In Knoxville, shifting ground can throw a gate’s alignment off, then the extra weight and movement strain the hinges. We reinforce gate posts with deeper footings and use heavy-duty hinges and latches. We also check the soil around the post. If the problem started after a wet spring or dry summer, it likely has a foundation issue we can fix by re-setting the post properly.

Gaps form when posts move independently due to soil expansion or rot at the base. In Knoxville’s humidity, wood posts can decay faster if not treated. We use pressure-treated lumber or steel posts with gravel drainage around the base to combat moisture buildup. For new installations, we space sections with allowed movement in mind so they don't pull apart. For repairs, we can replace a single compromised post and re-secure the rails to close up those gaps.
