Planning a new deck and wondering what the materials will actually cost? Composite decking prices vary widely depending on the brand, grade, and board profile you choose — anywhere from $3 per square foot for entry-level products to $12 or more for premium capped composites. Understanding where those dollars go helps you build a realistic budget and avoid sticker shock at the lumberyard.
Average Cost by Grade
Composite decking falls into three general tiers, and the price gaps between them are significant. Here is what to expect for materials only, before installation labor.
- Budget/entry-level: $3-$5 per sq ft — brands like MoistureShield Vantage and Fiberon Good Life
- Mid-range: $5-$8 per sq ft — Trex Select, TimberTech Edge, Fiberon Symmetry
- Premium: $8-$12+ per sq ft — Trex Transcend, TimberTech Azek Vintage, Fiberon Paramount
A standard 12 x 16-foot deck (192 sq ft of decking surface) would cost roughly $575-$960 for budget boards, $960-$1,535 for mid-range, and $1,535-$2,300+ for premium — materials only.
Price Breakdown by Popular Brand
Trex
Trex is the most recognized composite brand in the US. Their lineup starts with Trex Enhance Basics at around $4.00-$5.50 per sq ft, moves up to Trex Enhance Naturals at $5.50-$7.00, and tops out with Trex Transcend Lineage at $9.00-$11.00. A 16-foot grooved board in the Transcend line retails for roughly $55-$65.
TimberTech / Azek
TimberTech offers both capped composite (Edge and Legacy lines) and capped polymer (Azek). The composite boards range from $5.00-$8.50 per sq ft, while Azek polymer boards — which contain no wood fibers and resist moisture even better — run $9.00-$13.00 per sq ft.
Fiberon
Fiberon tends to undercut Trex and TimberTech slightly at each tier. Their Good Life line starts around $3.50 per sq ft, Symmetry sits at $5.00-$7.00, and Paramount PVC boards reach $8.00-$10.00. Fiberon is widely available at Lowe’s.
Installation Labor Costs
Professional deck installation typically runs $8-$22 per square foot for labor, depending on the complexity of the design and your local market. That number includes framing, decking, and basic railing. A straightforward rectangular deck on flat ground sits at the lower end; multi-level decks with curves, built-in benches, or pergola attachments push toward the higher end.
For that same 192 sq ft deck, budget $1,535-$4,225 for labor. Combined with materials and fasteners, total project costs land in the $3,000-$7,500 range for most homeowners. Complex builds easily exceed $10,000.
Hidden Costs to Factor In
- Substructure framing: Pressure-treated joists and posts add $2-$4 per sq ft if you are building from scratch
- Fasteners: Hidden clip systems run $80-$200 per 100 sq ft; face screws cost less but leave visible holes
- Railing: Composite railing kits cost $30-$75 per linear foot; aluminum is $50-$100+
- Permits: Most municipalities require a building permit for decks over 200 sq ft or 30 inches above grade — typically $75-$500
- Stairs: Each set of stairs adds $300-$800 depending on height and railing
Composite vs. Wood: Long-Term Value
Pressure-treated lumber decking costs just $1.50-$3.00 per sq ft for materials, making it look like a bargain upfront. But wood decks need staining or sealing every one to three years ($0.50-$1.50 per sq ft each time), and they typically last 10-15 years before boards start warping and rotting.
Composite decking prices are higher initially, but most manufacturers offer 25-50 year warranties against fading, staining, and structural defects. Over a 25-year period, composite often costs less than wood when you factor in maintenance expenses and replacement cycles.
Ways to Save on Composite Decking
- Shop end-of-season sales in September and October when retailers clear inventory
- Choose grooved boards over square-edge — they are often $1-$2 cheaper per board and hide fasteners with clips
- Stick with standard colors; specialty finishes carry a premium
- Buy directly from big-box stores (Home Depot, Lowe’s) where pricing tends to be lower than specialty dealers
- Handle demolition of the old deck yourself to cut labor costs by $500-$1,500
- Keep the design simple — every angle, curve, or level change adds labor hours
When to Buy: Seasonal Pricing Trends
Composite decking prices follow a predictable seasonal curve. Demand peaks between March and June when homeowners start outdoor projects, and retailers rarely discount during this window. The best deals land in late September through November as stores clear summer inventory. Some big-box retailers mark down composite boards 15-25% during fall clearance events. Ordering materials in winter and scheduling installation for early spring can also save money since contractors offer lower labor rates during their slow season.
Getting Accurate Quotes
Request at least three itemized quotes from licensed deck builders. Make sure each quote separates materials, labor, fasteners, railing, and permits so you can compare apples to apples. Ask about their preferred composite brand and whether the quote includes the substructure or just the decking surface.
Composite decking prices have stabilized after supply-chain spikes in recent years, and the selection of colors and textures keeps improving. Whether you choose a budget board or a top-tier capped polymer, you are investing in a low-maintenance outdoor space that holds up far better than wood over the long haul.
