Jay James construction | Reliable Commercial Fencing in Laplace, LA

The primary cause is prolonged exposure to moisture from our area's frequent rainstorms and localized flooding. In LaPlace, especially near neighborhoods like Belle Chase or the Reserve, soil stays damp for days after heavy rains. When fence posts are set directly in this wet ground without proper drainage or treatment, the wood absorbs water and eventually rots from the base. That’s why we always inspect for standing water and recommend using pressure-treated posts with gravel footings.

Look for visible leaning or sagging sections, especially along the bottom rail. After a flood event near the Mississippi River or Lake Pontchartrain, you might also notice spongy or crumbling wood where the posts meet the ground. Another clear sign is if the gate drags or won’t latch properly—this often means the post base has expanded or rotted. If you see mushrooms growing near the post base or a musty smell, that’s a sure sign moisture has set in. A quick call to a carpenter can confirm the damage.

The most effective solution is a combination of proper grading and professional installation. First, we check the slope around the fence line—if water pools near the posts, we recommend regrading or adding a French drain. Second, we install all posts in a gravel-and-concrete mixture that lets water drain away from the wood. Using stainless steel or galvanized hardware also prevents rust from moisture. And since plumbing issues often contribute to pooling water, we always include a plumbing inspection as part of the build. This way, we fix any hidden leaks before they rot your new fence.
