When comparing Trex or other capped composite decking to traditional wood, buyers typically see clear cost drivers: material price per square foot, installation labor, and long-term maintenance. This article breaks down the price ranges in dollars, including low, average, and high estimates, to help plan a budget for a standard 200 square foot deck.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material (Trex/Capped Composite per sq ft) | $4.50 | $6.50 | $9.50 | Includes basic boards and hidden fasteners |
| Material (Standard Wood per sq ft) | $2.00 | $3.50 | $5.00 | Pine or pressure-treated; higher for hardwoods |
| Installation Labor (per sq ft) | $2.50 | $4.00 | $6.50 | Labor varies by site access |
| Total Installed Cost (per sq ft) | $7.00 | $10.50 | $16.00 | Composite tends higher; wood varies with finish |
| Total Installed for 200 sq ft Deck | $1,400 | $2,100 | $3,200 | Assumes standard framing and flashing |
Assumptions: Midwest labor rates, standard one-story deck, no advanced railing systems, basic permits if required.
Material Cost Breakdown for Trex and Wood Decking
Trex and similar capped composites cost more per square foot upfront, but offer longer lifespans and lower maintenance. For Trex, expect roughly $4.50-$9.50 per sq ft for boards and fasteners. Wood decking ranges from about $2.00-$5.00 per sq ft, depending on species and quality. A typical 200 sq ft deck materials alone can run $900-$1,700 for composite versus $400-$1,000 for wood. The difference widens if premium woods or exotic species are chosen. Assumptions: standard 2×6 boards, concealed fasteners for Trex, pressure-treated pine for wood.
| Component | Trex/Capped Composite | Wood Decking |
|---|---|---|
| Board Price per sq ft | $4.50-$9.50 | $2.00-$5.00 |
| Fasteners and Trim per sq ft | $0.50-$1.50 | $0.20-$0.80 |
| Underlayment/Footing per sq ft (approx) | $0.20-$0.60 | $0.15-$0.50 |
| Substructure (framing) per sq ft | $2.00-$4.50 | $1.00-$3.00 |
Labor and Installation Rates by Deck Size
Labor costs are a major differentiator between Trex and wood projects. Typical installation ranges per square foot: 2.50-$6.50 for Trex and 1.80-$4.50 for wood, depending on access, railing complexity, and whether stair work is included. A standard 200 sq ft deck often requires 2-4 days of crew time. Larger or more intricate railings, built-ins, or lighting can push costs higher. Assumptions: local union/non-union rates, standard access, no solar installations.
- Trex: 200 sq ft at $2.50-$6.50 per sq ft = $500-$1,300 in labor for basic framing and decking.
- Wood: 200 sq ft at $1.80-$4.50 per sq ft = $360-$900 in labor for basic framing and decking.
Regional Price Differences Across the United States
Geography matters: coastal cities and the Midwest show distinct price bands for both materials and labor. On average, Trex installation can be 5-15% higher in the Northeast and West compared with the Southeast or Midwest due to labor rates and material sourcing. Composite costs can swing by about 10-20% regionally, while wood costs are more sensitive to local species availability. Assumptions: typical climates, standard access, no major site prep.
Maintenance, Longevity, and Long-Term Costs
Maintenance cycles heavily influence the “price” of each option over time. Trex decks generally require cleaning and occasional sealing-less maintenance, with long-term cost advantages in stain resistance and rot protection. Wood decks may need yearly to biannual sealing or staining, weatherproofing, and more frequent board replacement in high-traffic areas. Over a 20-year horizon, Trex can cost less per year when factoring maintenance avoidance, but up-front pricing remains higher. Assumptions: standard climate, typical wear, normal usage.
| Cost Driver | Trex Impact | Wood Impact |
|---|---|---|
| Annual Maintenance Cost (est.) | $0-$150 | $150-$400 |
| Board Replacement Frequency (years) | 10-25 | 5-15 |
| Finish and Sealing Needs | Minimal | Common |
Key price drivers: size, material, and system type
Size matters most for per-square-foot pricing, while material choice shifts the balance of upfront vs long-term costs. A 12×14 ft deck (168 sq ft) would show composite material premium of roughly 30-60% over wood at installation, driven by board density, hidden fasteners, and substructure choices. If choosing a composite with a high-end railing system or lighting, expect a multiplier on the total. Assumptions: standard railing height, simple straight spans, no elevated zones.
Ways to reduce decking costs without sacrificing durability
Control scope and timing to lock in better quotes. Consider using fewer railing post-holes, selecting mid-range Trex colors, or replacing only marquee areas instead of the entire deck. Compare multiple quotes, bundle delivery/dump fees with installation, and look at alternative boards within the same material family. Replacing damaged boards rather than full deck replacement is another common cost saver. Assumptions: market pricing varies, no seasonal rush fees.
