What are the common problems with chain link in South Florida?
Rust and corrosion
Humidity and salt air attack bare steel. Hot-dip galvanized parts hold up better than cheaper coatings, and vinyl-coated mesh adds another layer. Ask what fittings, ties and hardware come with the quote, since rusty small parts are often the first thing to fail.
Wind
Open mesh lets wind through, which helps in a storm. Adding privacy slats or windscreen fabric turns the fence into a sail, so those add-ons need stronger posts and fixings. Ask how the fence is designed for the addition.
Sagging and leaning
Loose mesh, bent top rails and leaning corner posts show up when the original tension or footings were weak, or when a vehicle has struck the fence. A properly set post and a tight stretch prevent most of this.
Rules
HOAs commonly restrict chain link, especially in front yards. Cities also set rules on height and on barbed wire or similar toppings, so check before you plan a security fence.
