A wood fence in Miami has to do two jobs that pull against each other. It has to give you privacy, and it has to let air move. Get the first one right and ignore the second, and you’ve built a sail in a county that sees tropical storms most summers. The style you choose — not just the height — is what balances those two jobs.
We build three wood fence styles for backyards across Miami-Dade and Broward: picket, shadow box, and privacy. All three use the same material, pressure-treated southern yellow pine, which is the right wood for this climate. What changes between them is the layout of the boards, and that layout decides how much you can see through the fence, how much wind passes through it, and what the fence is actually good for.
Here’s how each one works.
What “pressure-treated pine” means here
Every wood fence we install is pressure-treated southern yellow pine. We don’t run cedar or other species, and in South Florida that’s a feature, not a limitation.
Pressure treatment forces preservative deep into the wood under pressure, which is what lets it stand up to the two things that destroy fences down here: constant moisture and ground contact. A backyard in Kendall or Homestead gets driving summer rain, high humidity nearly year-round, and soil that stays damp. Untreated wood rots from the post line up. Treated pine resists that, and the posts — the part that fails first — are the part that benefits most.
It’s the same material across all three styles. Picket, shadow box, and privacy are layouts, not different woods.
Picket: low, open, and friendly
The picket fence is the classic front-yard or low-backyard fence. Vertical boards spaced apart with a visible gap between each one, usually three to four feet tall, often with a pointed or rounded top.
- Sightlines. Open. You can see through the gaps from either side, and so can everyone else. A picket fence marks a boundary; it does not hide anything.
- Airflow. Excellent. The gaps mean wind passes straight through, so there’s very little load on the structure during a storm. Picket is the least wind-exposed of the three.
- Typical uses. Front yards, garden borders, dog runs, pool-adjacent areas where code allows, and any spot where you want definition without a wall. It keeps a small dog in and a property line clear.
A picket fence is the wrong tool if privacy is the goal. It’s the right tool if you want your yard to feel open and you’re mostly keeping things contained, not concealed.
Shadow box: privacy with airflow
Shadow box is the one most South Florida homeowners actually want once they understand it, and it’s the style in the photo above. Boards alternate from one side of the rail to the other, so a board on the front covers the gap between two boards on the back.
Look at it straight on and it reads as a solid fence. Walk past it at an angle and you’ll catch slivers of the yard behind it — which is why it’s sometimes called a “good neighbor” fence. It looks finished from both sides, with no clearly “ugly” back.
- Sightlines. Mostly private head-on, partly open at an angle. You get real privacy without the closed-in feeling of a full wall.
- Airflow. Good. Because the boards are offset rather than sealed edge to edge, wind moves through the gaps instead of slamming a flat surface. In hurricane country that matters — a fence that breathes is a fence under less load.
- Typical uses. Backyards where you want privacy but the lot catches a breeze, neighborhoods with HOA rules about finished appearance on both sides, and anywhere a solid privacy fence would feel like a box.
Shadow box is the middle path, and for a lot of Miami backyards it’s the most sensible one.
Privacy: full coverage, no gaps
The privacy fence is what most people picture when they say “wood fence.” Vertical boards butted edge to edge with no gaps, typically six feet tall, sometimes with a decorative lattice or cap on top.
- Sightlines. Closed. From either side, you see boards, not the yard. This is the style for a pool you don’t want overlooked, a patio you want to use without an audience, or a property line with a busy street behind it.
- Airflow. Limited by design. A solid fence catches more wind than picket or shadow box, which is exactly why the posts, footings, and rail spacing have to be right. Done correctly — proper post depth, concrete footings, treated lumber — a privacy fence holds up fine here. Done on the cheap, it’s the first thing to lean after a storm.
- Typical uses. Pool enclosures, full backyard privacy, blocking a view, screening equipment or trash areas.
Privacy is the right call when seclusion is the whole point. Just know that with a solid fence, the build quality underneath matters more than with any other style, because there’s more surface for the wind to push on.
How all three hold up in South Florida
The wood is the same; what separates a fence that lasts from one that doesn’t is how it’s set. Pressure-treated pine gives you the material advantage. Proper installation gives you the rest — post depth, concrete footings, correct spacing for the style, and hardware that won’t rust out in the salt-tinged humidity.
Style choice also feeds into the permit. Fence height and pool proximity change what the county or your city requires, and almost every fence in Miami-Dade needs a permit before the first post goes in. We pull the permit for the fences we install, so that part is handled — if you’re curious how it works, we wrote up whether you need a permit for a fence in Miami-Dade. Before any build, we run a property through MyHausFax™ so we know what’s already on record — open permits, prior work, lot specifics — before we start.
If you’ve got an older wood fence that’s leaning, graying, or losing boards, that’s usually a repair question rather than a full replacement, and we handle both.
The short version: picket for open boundaries, shadow box for privacy that still breathes, privacy for full coverage. All in treated pine, all built for the climate they’re standing in.
