| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Trex Sample Lumber (per linear ft) | $4.00 | $6.50 | $9.50 | Standard Trex boards, color varies |
| Substructure (framing, joists) | $2.50 | $4.00 | $6.50 | Pressure-treated or alloy joists |
| Labor for Installation (per sq ft) | $4.00 | $7.50 | $12.00 | Includes measuring and fastening |
| Fasteners & Accessories | $0.60 | $1.20 | $2.50 | Hidden fasteners or color-matched screws |

Assumptions: Midwest or Southeast markets, standard 5/4×6 or grooved boards, normal access, weather window non-restrictive.
Trex Board Price Range by Deck Size and Grade
Pricing scales with deck size and profile: longer boards and embossed textures push per-ft costs higher. For a 250 sq ft deck using 16-foot grooved boards, expect $9-$14 per sq ft for materials, plus $4-$7 per sq ft for labor. A smaller 100 sq ft project may land on the lower end of that range, while a larger 500 sq ft installation approaches the higher end when premium colors or railing integration is included. Assumptions: standard residential installation, moderate slope, no fascia work.
Material Costs: Trex vs Other Composite Options
Trex board prices sit above basic composite options but below premium exotic hardwoods. Typical material ranges: Trex $4.50-$7.50 per linear ft for most lines; alternatives like other composites run $3.50-$6.50 per linear ft, and hardwoods can exceed $8.00 per linear ft. For a 200 sq ft area using 12 ft boards, materials total often lands around $1,100-$1,900 for Trex, plus installation costs. Assumptions: standard 5/4 x 6 boards, no bulk discount, regional freight included.
Labor and Tools Impact on Trex Decking Project
Labor intensity rises with elevation, complex layouts, and hidden-fastener systems. Typical labor ranges: $4-$7 per sq ft for basic install, $7-$12 per sq ft for elevated or curved layouts, plus tool rental where needed. For a 300 sq ft deck, total installed price may be $2,100-$4,800 in labor, depending on joist replacement and substrate repair. Assumptions: standard height, acceptable access, no extensive demolition.
Fasteners and Accessories Price for Trex Installations
Hidden fasteners and color-matched screws add measurable cost but improve aesthetics and spacing accuracy. Accessories typically run $0.60-$2.50 per linear ft on top of board cost. For a 400 sq ft deck using hidden fasteners, expect $240-$1,000 in accessories depending on system chosen and color matching. Assumptions: grooved boards, standard joist spacing, no specialty trim.
Regional Price Variations for Trex Decking in the U.S.
Geography influences both material availability and labor rates. In the South and Midwest, installed Trex decks commonly price $15-$26 per sq ft total, while coastal regions with higher labor costs may reach $28-$40 per sq ft. A project in a rural area might see lower overall costs due to simpler access. Assumptions: typical home elevations, no luxury finishes, standard permits where required.
Installation Scope: Surface Prep and Substructure Costs
Deck preparation and substructure work can swing the budget by thousands. Surface prep (soil removal, leveling, moisture barriers) may add $1-$3 per sq ft, while substructure upgrades (replacing rotted joists) can add $2-$5 per sq ft. For a 350 sq ft deck with minor joist repair, total prep and frame work could be $1,200-$4,000. Assumptions: no structural remediation beyond standard wear.
Maintenance and Replacement Costs Over Time
Trex is marketed as low-maintenance, influencing long-term cost planning. Annual maintenance can be minimal, with occasional cleaning and stain touch-ups. Expect $0.20-$0.50 per sq ft per year for cleaning and sealing avoidance, or roughly $60-$180 per year for a 300 sq ft deck if periodic protection is used. Replacement cycles typically span 25-40 years, depending on climate and usage. Assumptions: typical user upkeep, moderate sun exposure.
Permits, Warranties, and Financing Implications
Permits and warranties affect the total price through fees and coverage gaps. Permits may range from $0 to $300 depending on city and scope. Trex warranties vary by product line but generally cover materials for 25 years; labor warranties are often offered by installers and can add 1-2% to project cost if extended. Financing or credit options can influence upfront price through interest or promo plans. Assumptions: single-family residence, standard deck footprint, no structural upgrades mandated by code.
Cost Components Table
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Trex Board Lengths (per ft) | $4.00 | $6.50 | $9.50 | Grooved or square-edge options |
| Substructure Material | $2.50 | $4.00 | $6.50 | Pressure-treated or metal framing |
| Labor (per sq ft) | $4.00 | $7.50 | $12.00 | Includes layout and fastening |
| Fasteners & Accessories | $0.60 | $1.20 | $2.50 | Hidden fasteners often used |
| Delivery | $0.15 | $0.40 | $1.10 | Depends on distance |
| Permits & Fees | $0 | $150 | $300 | Location dependent |
Formula example: labor cost = labor hours × hourly rate. For a 300 sq ft deck at 6 hours of labor per 100 sq ft and $8/hour, labor ≈ $14,400 total.
