323 Fence Company | Trusted Wood and Vinyl Fencing in San Antonio, TX

San Antonio's clay-rich soil expands when wet and contracts when dry. This constant movement can loosen fence posts over time, especially if they weren't set with concrete or proper anchors. Heavy rains or drought cycles make it worse. The solution is to install posts with concrete footings that extend below the frost line, or retrofit existing posts with metal anchors to stabilize them.

Look for signs like fading color, peeling paint, or bare wood that feels rough. Discoloration from UV rays is common here. If you see small cracks or splinters, moisture is already getting in. Weatherproofing with a quality stain or sealant every 2–3 years protects against rain, sun, and humidity—keeping your fence from rotting or warping.

First, check if the posts are rotted or just loose. If the wood is sound, we can reset the post in a wider hole with fresh concrete and gravel for drainage. For severe cases, we might install a post anchor system that allows movement without compromising the fence. Sometimes adjusting the grading around the post to divert water helps prevent future shifting.
