Residential Fencing San Francisco CA | Call Mission Iron Works

San Francisco's coastal climate brings persistent fog and salty air, which accelerate rust on standard chain link fences. Moisture and salt combine to break down the galvanized coating over time, leading to orange-brown corrosion. This is especially common near the ocean or in areas like the Sunset District.

Look for visible tilting, uneven gaps between the fence and ground, or posts that shift when pushed. A leaning fence often indicates loose or rotted posts, especially after heavy rains or soil erosion in neighborhoods like Bernal Heights. If the lean exceeds 10 degrees, it's a safety concern that needs immediate attention.

We assess the cause—usually post movement or soil issues—and reinforce or replace the posts with concrete footings. For corrosion-damaged chain link, we install new galvanized or vinyl-coated sections. In the Mission District, we also recommend stainless steel hardware to prevent future rust. Our goal is a sturdy, long-lasting fence that stays straight.
