Professional Wood and Vinyl Fencing in Gainesville, VA 20155 - A & A Fencing

In Gainesville, with our wet clay soils and cold winters, freeze-thaw cycles can push fence posts upward. Look for visible signs like a post that is leaning, a gate that no longer latches properly, or gaps forming between the top rail and the post. If you notice the ground around a post is raised or cracked, that's a strong indicator the post is being pushed out of the ground.

The main culprit is our local climate: high humidity throughout the year, combined with periods of heavy rain and intense summer sun. This constant moisture exposure, especially at the ground line where wood rests on damp soil, speeds up rot. Additionally, the rapid drying from the sun can cause the wood's surface to check and warp. A & A Fencing combats this by using pressure-treated lumber and proper drainage techniques at the base.

We specifically use a deep-set installation method. For all new fences in Gainesville, we dig post holes well below the frost line—typically 30 to 36 inches deep. We then set the posts in a concrete collar that extends above the soil line to prevent water from pooling at the base. This concrete base is also shaped to slope away from the post, directing water runoff and minimizing frost heave.
