Juan Caal - New Orleans's Expert Fencing Company

Rust on metal fences is typically caused by prolonged exposure to moisture, high humidity, and salt in the air—common conditions throughout New Orleans. Flooding from storms or high groundwater can also accelerate corrosion. To prevent rust, Juan Caal recommends regular cleaning to remove dirt and salt, applying a rust-inhibiting primer, and using a high-quality exterior paint or sealant designed for metal. For existing rust spots, sanding down to bare metal, treating with a rust converter, and repainting can restore the fence and extend its life.

Flood damage can weaken fence posts, warp wooden sections, and cause metal components to corrode faster. For a thorough repair, Juan Caal inspects the entire fence line, replacing any rotted or rusted posts and resetting them in concrete for better stability. Damaged pickets, rails, or panels are either repaired or replaced. Concrete work around the base of posts helps anchor them against future high water. After repairs, a fresh coat of paint or sealant protects the fence from moisture. This approach addresses both the visible damage and the underlying structural issues caused by frequent flooding in neighborhoods like Lakeview and Gentilly.

Look for cracks wider than a hairline, large chips or sections breaking away, posts that lean or feel loose, and any rust stains coming from inside the post (which suggests rebar corrosion). In New Orleans, constant moisture from rain and occasional flooding can speed up concrete deterioration. If you notice crumbling near the ground line or the post doesn't sit straight, it's often best to replace it. Juan Caal can remove the old post, excavate the base, and set a new reinforced post in fresh concrete, ensuring your fence remains sturdy and secure for years.
