The main cause is the area's clay-heavy soil and high humidity. Clay soil retains moisture, which can seep into fence posts and cause them to rot or warp over time. Poor drainage from nearby lawns or irrigation systems can worsen the problem by keeping the soil consistently wet against the wood.

Look for signs like discoloration at the bottom of fence boards, soft or spongy wood near the ground, or visible mold and mildew. You might also notice that the soil around the fence posts stays muddy or damp long after watering or rain. If your sprinklers are hitting the fence directly, that's another red flag.

First, we assess the damage and identify the moisture source—often an irrigation head that's misaligned or a drainage issue. We can repair or replace damaged fence sections, adjust your irrigation system to keep water away from the wood, and improve drainage around the posts. For new fences, we recommend using pressure-treated wood or composite materials and installing proper gravel bases to prevent future rot.
