Penniston Fence: Professional Fencing Company Serving Florissant, MO 63033

The primary cause is our region's clay-rich soil, which expands when wet and contracts during dry spells. This movement, combined with freezing temperatures, can push posts upward. Penniston Fence resolves this by setting posts below the frost line (typically 30-36 inches deep) and using concrete footings with proper drainage gravel. For existing heaving, we can reset and brace the posts, then backfill with a non-expansive gravel mix to prevent future movement.

A sagging gate that drags on the ground or won't latch properly is often a sign of post movement rather than simple hinge wear. If the gap between the gate and the latch post changes with the seasons, it's likely soil-related. Penniston Fence will inspect the post foundation first. If the post is stable but the gate is heavy, we can add a tension cable or upgrade to heavier-duty hinges. For posts that have shifted, we'll re-set them with a deeper, frost-proof foundation.

In many cases, we can repair individual warped or rotted panels without replacing the entire fence. For moisture-related warping in Florissant, we often recommend replacing affected pickets or sections with pressure-treated or cedar wood that's more resistant to humidity. We also check the drainage around the fence line to ensure water isn't pooling at the base. If the posts are still solid, a targeted repair is much more cost-effective than a full rebuild.
