Deck skirting closes off the open space beneath an elevated deck. It cleans up the look, discourages pests, can create outdoor storage, and gives the whole structure a finished quality.
The most popular deck skirting options are traditional wood lattice, vinyl lattice, horizontal wood planks, vertical boards, composite skirting, and metal panels. Each behaves differently over time, costs differently to install, and fits different home styles.
Why Under-Deck Ventilation Matters Before You Pick a Material
The USDA Forest Products Laboratory has documented that decks and balconies are among the most moisture-vulnerable parts of any residential structure, and that trapping humid air beneath them can rot your framing, even if the deck boards above are composite.
Any skirting approach you choose needs either built-in gaps, perforated panels, or dedicated vent cutouts. That requirement shapes the options below.
Top 6 Deck Skirting Options
1. Traditional Wood Lattice
The classic. Wood lattice panels in a diagonal grid pattern have been the default under-deck finish for decades, and they remain the most affordable starting point.
Pros:
- Cheapest material cost at roughly $1–$2 per square foot for panels
- Available at every home improvement store, no special ordering
- The open grid handles ventilation without any extra planning
- Supports climbing plants if you want greenery along the base
Cons:
- Needs repainting or restaining every 2–3 years without exception
- The diamond grid catches leaves and debris
- Prone to warping in wet climates, which throws off the consistent spacing over time
- Looks dated on modern deck designs
Cost installed: $500–$1,500 for a typical deck, depending on size and the amount of trim and framing involved. Small decks can come in lower; larger perimeters will push past that range.
2. Vinyl Lattice Panels
Vinyl lattice, especially in black, has become a popular upgrade over wood because it holds its shape and color through weather that would warp or fade wood panels.
Pros:
- Never needs painting — color is consistent throughout the material
- Resistant to moisture and insects
- Grid spacing stays uniform over time, unlike wood lattice that shifts as it weathers
- Black vinyl reads as more contemporary than white-painted wood lattice
Cons:
- Higher upfront cost than wood
- Lightweight panels can flex in wind if the frame isn’t solid
- Limited color options compared to paintable wood
Cost installed: $600–$1,400 for an average deck. Black vinyl lattice panels at retail run about $53–$60 for a 4×8 sheet, or $1.65–$1.90 per square foot for materials before labor.
3. Horizontal Wood Planks
This is where skirting starts looking intentional rather than cosmetic. Horizontal planks run parallel to the ground with small, consistent gaps between them, which naturally handle ventilation and give the deck a clean, architectural silhouette.
Pros:
- Creates a visual connection between the deck surface and the skirting below
- Natural wood grain adds warmth that composite and vinyl can’t fully replicate
- Gap spacing provides airflow without separate vent panels
Cons:
- Wood at grade level is vulnerable, needs diligent sealing
- More labor-intensive to install than lattice
- Indiana’s freeze-thaw cycles are hard on wood that isn’t resealed consistently
Cost installed: $900–$2,500 for a mid-size deck, depending on wood species and complexity.
4. Vertical Boards
The same material logic as horizontal planks, but oriented vertically. The visual effect is different: vertical lines draw the eye downward, which tends to ground a tall elevated deck visually and suits homes with board-and-batten or farmhouse exterior styles.
Pros:
- Works well on taller decks where visual grounding is a design concern
- Good fit for traditional and farmhouse-style homes
- Can use cedar, pine, or pressure-treated lumber
Cons:
- Bottom edge is the most moisture-vulnerable point on the board
- Gap management requires more care than lattice, where the grid does the spacing work
- Similar maintenance demands to horizontal planks
Cost installed: $700–$2,000. Comparable to horizontal planks, but can run lower with simpler lumber choices.
5. Composite Deck Skirting
Composite boards used as skirting material are the most durable long-term answer on this list. The same boards that go on a composite deck surface, installed vertically or horizontally as skirting, create a cohesive and maintenance-free finish.
If you’re still weighing materials for the deck itself and want a full breakdown, the Decks On Point guide to composite vs. wood decking covers the tradeoffs in detail.
Pros:
- No sealing, staining, or sanding. Ever.
- Resistant to moisture, insects, and UV fading
- Matches composite deck boards above for a unified, polished look
- Entry-level composites carry 25-year warranties; premium lines from brands like TimberTech AZEK carry 50-year fade-and-stain warranties
Cons:
- Higher upfront cost than any wood option
- Solid composite skirting panels need a planned access door for storage access, there’s no built-in opening
- Precise cutting and framing make this a poor candidate for DIY
Cost installed: $1,200–$3,500, depending on composite tier and deck perimeter.
6. Metal Panels
Powder-coated aluminum or steel panels in black or gray are the most visually striking skirting option and the one most commonly seen on newly built contemporary homes. Paired with cable railing and composite deck boards, metal skirting makes a sharp, cohesive statement.
Pros:
- Zero maintenance, no painting, no sealing, no rot
- Creates a very strong modern aesthetic when it matches the railing system
- More of a security barrier than any other option; solid metal is harder to breach than lattice or wood planks
Cons:
- The most expensive option by a meaningful margin
- Looks out of place on traditional, rustic, or colonial-style homes
- Ventilation requires deliberate planning, perforated panels, cutouts, or gap spacing built into the design
Cost installed: $2,000–$5,000 or more, depending on panel finish, size, and custom fabrication.
Deck Skirting Costs at a Glance
| Approx. Installed Cost | Maintenance Level | |
| Wood lattice | $500–$1,500 | High |
| Vinyl lattice | $600–$1,400 | Low |
| Horizontal wood planks | $900–$2,500 | Moderate |
| Vertical boards | $700–$2,000 | Moderate |
| Composite boards | $1,200–$3,500 | Very Low |
| Metal panels | $2,000–$5,000+ | Very Low |
These are installed ranges. If you’re comparing material-only costs, wood lattice panels run about $1–$2 per square foot at retail. Vinyl lattice panels run about $1.65–$1.90 per square foot. Everything above those figures is labor, framing, trim, and hardware.
How to Choose Your Deck Skirting
A few questions that actually narrow it down:
- Does your home have a defined architectural style? Traditional and craftsman homes read best with wood lattice or vertical boards. Modern homes get more out of horizontal composite planks, metal panels, or black vinyl lattice.
- How much maintenance are you genuinely willing to do? If the answer is “as little as possible,” composite skirting or vinyl lattice is your range.
- Do you need access to the space beneath? Every skirting design should include an access door, especially if you’re using the under-deck area for storage. Composite and metal skirting especially need this planned in from the start.

Frequently Asked Questions
Does deck skirting require ventilation?
Yes. Most local building departments require adequate airflow when enclosing the space under a deck. Without it, moisture accumulates against the framing, and wood rot follows, even in pressure-treated frames.
Can I add skirting to an existing deck?
In most cases, yes. It’s one of the more straightforward deck improvement projects because it doesn’t touch the structural framing. You’ll need a frame to attach panels to, and you’ll want to inspect the existing structure first.
What’s the most low-maintenance skirting option?
Composite boards and vinyl lattice are the two best answers. Both resist moisture, insects, and UV without annual treatment. Composite has the edge on longevity and aesthetics; vinyl lattice has the edge on upfront cost.
How do I keep animals out from under my deck?
Any skirting with openings needs gaps no larger than 1/4 inch to block small rodents like mice and rats. For burrowing animals like groundhogs and skunks, the skirting itself isn’t enough. Bury a strip of 1/4-inch hardware cloth along the perimeter, extending at least 12 inches into the ground, and bend the bottom of the mesh outward in an L-shape.
Is composite skirting worth the extra cost?
For homeowners who already have a composite deck and plan to stay in the house long-term, yes. Over a 15-to-20-year period, the savings on staining, repairs, and board replacement typically offset the higher installation cost.
Someone Else Can Handle This Part
Picking the right material is one thing. Framing it properly, managing ventilation, cutting panels to fit a non-square perimeter, and adding an access door that actually opens cleanly is another project entirely.
At Decks On Point, skirting is part of a finished deck, not an add-on afterthought. Whether you’re adding it to an existing structure or building new, we’ll help you choose what fits your home and install it with the same attention we put into everything else.
