River Stone Construction: Experienced Fence Contractors Serving San Antonio, TX 78207

The primary cause is the expansive clay soil common throughout San Antonio, especially in areas like Stone Oak and Alamo Heights. When this soil gets wet it swells, and when it dries out it shrinks, causing the ground around a fence post to shift. Over time, this movement loosens the post in its hole. River Stone Construction solves this by excavating the post and setting it in a deep concrete pier that extends below the active soil layer, providing a stable base that won’t shift with seasonal moisture changes.

Vines, climbing roses, and overgrown shrubs push against fence boards and trap moisture against wood or metal, which leads to rot, rust, and warped panels. In neighborhoods like the Dominion or Olmos Park, this is a common sight. River Stone Construction recommends a two-step solution: first, cutting back any vegetation that contacts the fence, and second, installing a gravel or mulch bed along the fence line to improve drainage and prevent plants from rooting against the structure. For new installations, we can also pour a concrete mow strip to keep growth at a distance.

Look for posts that wiggle when you push them, gates that sag or drag on the ground, and cracked concrete around post bases. Also check for fence boards that are pulled away from the rails or have soft spots from rot. If you notice any of these signs, catching them early can save you money. River Stone Construction can inspect your San Antonio fence, reinforce the weak posts with concrete footings, and replace damaged sections so the whole fence stays solid through our hot summers and occasional heavy rains.
