Why Composite Decking Has Taken Over
Twenty years ago, composite decking was a niche product with a mixed reputation — early versions faded, stained, and felt more like plastic than wood. Those days are over. Today's capped composite boards are virtually indistinguishable from premium hardwood at a glance, and they deliver something no wood product can: decades of use with almost zero maintenance. No staining, no sealing, no sanding, no splinters.
For Staten Island homeowners specifically, composite's advantages are amplified by the local climate. Salt air corrodes fasteners and accelerates wood decay. Humid summers promote mold growth. Freeze-thaw cycles crack and warp wood boards season after season. Composite handles all of these stresses without deteriorating, which is why it has become the most popular decking material we install — surpassing pressure-treated wood in demand for the first time in 2024.
This guide goes deeper than our general deck building guide to cover everything specific to composite: how brands compare, what capped vs. uncapped means, realistic cost expectations, color and texture options, and the limitations you should know before committing.
How Composite Decking Is Made
Understanding what's inside composite boards helps explain their performance characteristics and price differences. All composite decking combines two primary ingredients: wood fibers (sawdust, wood flour, or wood chips) and plastic polymers (high-density polyethylene, polypropylene, or PVC). The ratio and manufacturing process vary by brand, but typical composites are roughly 50 to 60 percent wood fiber and 40 to 50 percent polymer.
The wood fibers give composite boards their texture, weight, and some structural rigidity. The plastic polymers provide moisture resistance, dimensional stability, and binding strength. The two materials are heated, mixed, and extruded into board profiles that mimic the dimensions of standard lumber — typically 5.5 inches wide and available in 12, 16, and 20-foot lengths.
Capped vs. Uncapped: The Critical Distinction
Capped composite has a protective polymer shell — typically polyethylene or acrylic — wrapped around the core material on all four sides. This cap is what makes modern composites so durable. It creates a non-porous surface that blocks moisture penetration, resists UV fading, prevents mold and mildew growth, and makes the board far more resistant to scratching and staining than the core material alone. Virtually all premium composite decking sold today is capped.
Uncapped composite exposes the core material directly. Without the protective shell, the wood fibers in the core absorb moisture, swell, and can develop mold. UV exposure fades the color more rapidly. Uncapped boards are significantly cheaper — roughly 30 to 40 percent less than capped — but the trade-off in lifespan and appearance retention is substantial. We generally recommend uncapped composite only for hidden structural elements, utility areas, or budgets that can't accommodate capped products.
Always choose capped composite for your deck surface. The price premium of $2 to $4 per square foot over uncapped pays for itself in appearance retention and lifespan alone. Uncapped composite from ten years ago is the source of most negative composite decking stories you'll find online — fading, staining, mold growth — and doesn't represent what modern capped products deliver.
Top Composite Decking Brands Compared
Three brands dominate the composite decking market, and all three are available through Staten Island contractors. Each offers multiple product tiers at different price points.
Trex
Trex is the largest composite decking manufacturer in the world and the name most homeowners recognize. Their product line includes three tiers: Trex Enhance (entry-level capped composite, $4 to $6 per square foot for materials), Trex Select (mid-range with deeper woodgrain textures, $5 to $7), and Trex Transcend (premium with the most realistic wood appearance and best fade resistance, $7 to $10). All Trex products are capped and carry 25-year fade and stain warranties.
Trex is made from 95 percent recycled materials — a genuine selling point for environmentally conscious homeowners. The color range spans traditional wood tones (Saddle, Tiki Torch, Lava Rock) through contemporary grays (Gravel Path, Island Mist, Pebble Grey). Trex Transcend boards feature multi-tonal streaking that closely mimics the natural variation in real hardwood.
TimberTech / AZEK
TimberTech offers two distinct product lines under one brand. TimberTech PRO and TimberTech EDGE are capped composite products that compete directly with Trex at similar price points ($5 to $9 per square foot). TimberTech Advanced PVC (AZEK) is a different category entirely — it's 100 percent synthetic with no wood fibers, making it completely impervious to moisture. AZEK runs $9 to $14 per square foot for materials and is the premium choice for waterfront and pool decks where moisture exposure is constant.
TimberTech's composite lines feature a proprietary cap technology they call "Protective Polymer Capping" that includes built-in UV inhibitors and mold resistance. Their color palette emphasizes natural wood aesthetics, with standout options like Pecan (warm brown), Driftwood (gray-brown), and Mahogany (deep red-brown).
Fiberon
Fiberon occupies a strong value position — delivering capped composite performance at prices typically 10 to 20 percent below Trex and TimberTech for comparable products. Their Fiberon Good Life line starts at $3.50 to $5 per square foot, making it the most affordable capped composite on the market. Fiberon Symmetry ($5 to $7) and Fiberon Concordia ($7 to $9) step up in appearance and fade resistance.
Fiberon boards use a three-sided cap (top and both edges) rather than four-sided capping on their entry-level products, which is worth noting — the bottom is exposed core. For face-up deck boards this is rarely an issue, but for applications where the underside is visible (elevated decks, multi-level transitions), four-sided capping from Trex or TimberTech may be preferable.

Composite vs. Wood: The Real Comparison
The composite vs. wood debate comes down to how you weigh upfront cost against long-term cost, and how much value you place on maintenance-free living.
Upfront Cost
Composite costs roughly 2 to 2.5 times more than pressure-treated wood for materials and installation. A 300-square-foot pressure-treated deck runs $4,500 to $9,000 installed; the same deck in mid-range composite costs $10,500 to $21,000. That's a significant difference, and it's the primary reason wood still holds market share.
Lifetime Cost
Over a 25-year span, the math shifts. A pressure-treated deck needs staining or sealing every 2 to 3 years (roughly $300 to $600 per application for a 300-square-foot deck), periodic board replacements as individual boards rot or warp ($200 to $500 per repair), and a possible partial rebuild around year 15. Total 25-year maintenance cost: $4,000 to $8,000. Composite maintenance cost over the same period: effectively zero beyond occasional soap-and-water cleaning. The break-even point — where composite's lower maintenance cost offsets its higher upfront price — typically falls around year 8 to 10.
Appearance Over Time
This is where composite wins decisively. A new pressure-treated deck looks good, but within 6 to 12 months the wood grays and weathers unless stained immediately. Even with regular staining, wood develops hairline cracks, raised grain, and wear patterns from foot traffic. A capped composite deck looks essentially the same on year 15 as it did on year one — the color stabilizes after initial "weathering" in the first few weeks and then holds steady for decades.
When Wood Still Wins
Natural wood has qualities composite can't fully replicate. The warmth and grain of real cedar or Ipe hardwood is genuinely different from composite's simulated woodgrain — you can see and feel the difference up close. Wood stays cooler underfoot in direct sun. And if budget is the overriding factor, pressure-treated wood delivers a solid, attractive deck at half the price of composite.

Colors and Styles for Staten Island Homes
Composite decking comes in a wider range of colors and textures than most homeowners expect. The key is matching the deck color to your home's exterior, not choosing a color in isolation at the showroom.
Warm Browns and Tans
Colors like Trex Tiki Torch, TimberTech Pecan, and Fiberon Warm Sienna complement traditional homes with warm-toned brick, stone, or beige siding. These are the most popular choices for Staten Island's colonial and ranch-style homes in neighborhoods like Great Kills, Annadale, and Eltingville.
Weathered Grays
Gray tones (Trex Island Mist, TimberTech Driftwood, Fiberon Castle Gray) have surged in popularity over the past five years. They pair beautifully with white, light gray, or blue siding and create a contemporary coastal feel that suits Staten Island's waterfront neighborhoods. Gray decking also hides dirt and footprints better than dark browns.
Deep and Dark Tones
Rich brown and espresso tones (Trex Lava Rock, TimberTech Mahogany, Fiberon Rosewood) create dramatic contrast against lighter homes and landscaping. They look stunning when paired with white or black aluminum railings. The trade-off: darker colors absorb more heat and show scratches more readily than lighter options.
Installation Considerations
Composite decking installs on a standard pressure-treated wood substructure — the joists, beams, and posts are still wood. This is an important point that surprises many homeowners: your "composite deck" is roughly 50 percent wood by structural volume. The composite boards are the visible surface, but the bones of the deck are pressure-treated lumber.
Joist spacing is critical. Most composite products require 16-inch on-center joist spacing for standard perpendicular installations and 12-inch spacing for diagonal or herringbone patterns. The increased flexibility of composite compared to solid wood means tighter joist spacing is needed to prevent sagging and bounce. Your contractor should follow the manufacturer's specific requirements — deviating can void the warranty.
Hidden fastener systems are standard with composite decking. Rather than face-screwing through the board (which would create screw holes in the protective cap), hidden clips grip the edge groove of each board and pull it tight against the joist. The result is a clean, screw-free surface that looks better and eliminates the possibility of raised screw heads catching bare feet.
Thermal expansion is more significant with composite than wood. Composite boards expand and contract with temperature changes, and the installation must account for this with proper gapping between boards and at the ends. A board installed tight against a wall on a cold day will buckle when summer heat arrives. Experienced composite deck installers know the specific expansion gaps required for each product and season of installation. If you're planning deck lighting, have the low-voltage wiring run during construction — most composite post sleeve systems accept color-matched post cap lights and stair riser fixtures that integrate seamlessly.
Maintenance: What "Low Maintenance" Actually Means
Composite decking is marketed as "low maintenance" — not "no maintenance." Here's what you actually need to do to keep it looking its best.
Periodic cleaning (2 to 4 times per year) with soap and water or a composite deck cleaner removes pollen, dirt, mold spores, and food stains before they set. A soft-bristle brush and garden hose are all you need. Pressure washing is acceptable on most capped composites at low settings (under 1,500 PSI with a fan tip), but check the manufacturer's guidelines first — high-pressure washing can damage some cap surfaces.
Leaf and debris removal matters more than many homeowners realize. Wet leaves trapped between boards or in corners create a damp environment where mold can take hold even on capped composite. Keep the deck swept, especially in fall and after storms.
Furniture pads under metal chair legs, table bases, and planter bottoms prevent scratching the cap surface. Composite is scratch-resistant, not scratch-proof — dragging a metal patio chair across the surface will leave marks. Most minor scratches on capped composite can be buffed out with a heat gun or hidden with a matching touch-up pen from the manufacturer.
Salt air doesn't damage composite decking itself, but it can corrode metal fasteners and joist hangers in the substructure below. When building a composite deck in coastal Staten Island neighborhoods, insist on stainless steel or hot-dipped galvanized hardware throughout the substructure. The extra cost (roughly $200 to $400 for a typical deck) prevents premature structural failure that would undermine your investment in premium decking above.
Frequently Asked Questions
Is composite decking worth the extra cost over wood?
For most Staten Island homeowners, yes. While composite costs roughly twice as much as pressure-treated wood upfront, you eliminate all staining, sealing, and sanding costs — savings that total $3,000 to $6,000 over 25 years for a standard deck. The break-even point is usually around year 8 to 10, and a capped composite deck will still look like new when a wood deck of the same age needs major repairs or replacement.
Does composite decking get hot in the sun?
Yes, composite absorbs more heat than natural wood, and darker colors are noticeably hotter. On a 90-degree day, a dark composite board in full sun can reach 140 to 160 degrees — uncomfortable for bare feet. Choose lighter colors if your deck gets full afternoon exposure, or plan for shade with a pergola or umbrella. Some premium lines include heat-mitigating technology.
How long does composite decking last?
Capped composite from major brands lasts 25 to 50 years with 25-year fade and stain warranties. Uncapped composite lasts 15 to 25 years. The substructure (joists and beams) is pressure-treated wood and may need attention before the composite boards show wear. Regular cleaning and proper drainage extend lifespan significantly.
Can composite decking be installed over an existing wood deck frame?
Yes, provided the frame is structurally sound with correct joist spacing (usually 16 inches on center). This resurfacing approach saves 40 to 60 percent compared to a full rebuild. Your contractor should inspect joists, beams, and posts for rot, insect damage, and structural integrity before committing to a resurface.
