Prices for decking materials vary widely by product line, region, and installation details. This guide focuses on the cost and price ranges for Trex composite decking compared with pressure-treated wood, highlighting main cost drivers, typical per-square-foot pricing, and practical budgeting tips. Expect material costs to dominate, with installation labor and finishes adding to the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Trex Decking (boards, per sq ft) | $5.50 | $7.50 | $9.50 | Board quality and profile affect price |
| Pressure-Treated Decking (boards, per sq ft) | $1.80 | $3.10 | $4.50 | Standard 5/4×6 or 2×6 common sizes |
| Labor & Installation (per sq ft) | $3.50 | $5.50 | $8.00 | Includes framing, fasteners, basic finish |
| Fasteners & Hardware (per sq ft) | $0.30 | $0.60 | $1.20 | Hidden fasteners add cost for composites |
| Warranty & Maintenance (per sq ft, 1st year) | $0.05 | $0.15 | $0.35 | Composite often includes longer warranty |
| Delivery & Prep (flat or per project) | $100 | $350 | $800 | Depends on distance and site access |
| Permits (if required) | $0 | $50 | $200 | Local rules may apply |
Overview Of Costs
Cost varies by material type, deck size, and install complexity. Trex typically commands higher upfront material prices but offers lower maintenance costs over time. Pressure-treated wood starts with a lower sticker price but may incur more maintenance and shorter lifespan. This section presents total project ranges and per-unit estimates for standard 300–400 square-foot decks, assuming ground-level installation with basic railing. Assumptions: region, specs, labor hours.
Cost Breakdown
The cost breakdown below uses a table to show major cost categories and where money goes in a typical deck project. The per-square-foot figures assume a 350 sq ft deck and standard truckload logistics. data-formula=”labor_hours × hourly_rate”> Different regions and crew experience can shift these numbers.
| Category | Trex (per sq ft) | Pressure-Treserved Wood (per sq ft) | Notes |
|---|---|---|---|
| Materials | $7.00 | $2.50 | Composite vs treated wood; profile and color options affect Trex |
| Labor | $5.00 | $4.00 | Framing, decking installation, railing prep |
| Equipment | $0.50 | $0.60 | Joiners, saw rental, drills |
| Permits | $0 | $50 | Local code compliance |
| Delivery/Disposal | $0.80 | $0.70 | Material transport and waste removal |
| Warranty/Overhead | $0.20 | $0.15 | Labor and material protection |
| Taxes | $0.60 | $0.40 | Local sales tax varies |
What Drives Price
Material durability and maintenance needs drive long-term cost. For Trex, price is influenced by board profile (grooved vs solid), color, and presence of capped polymer layers. Pressure-treated wood price hinges on species (pine vs cedar), preservative treatment quality, and the added resistance features. Regional lumber markets, freight, and seasonal demand can create price swings of 10–25% year over year. A typical decking project balances upfront material cost against upkeep and replacement intervals.
Cost Drivers and Pricing Variables
Two key driver groups affect total spend: material specifications and installation complexity. Trex boards often require compatible hidden fasteners and longer joist spacing, which can add to costs if higher-grade framing is used. For pressure-treated wood, higher-grade boards, stain or sealant, and longer span requirements can raise both material and labor costs. Specialty finishes or railings add to the budget.
Ways To Save
The most effective savings come from balancing material life-cycle costs against upfront price. Consider: choosing a lower-profile Trex line for a smaller deck, bundling delivery, or using standard railing options instead of custom elements. For pressure-treated installations, selecting kiln-dried framing and applying a quality sealant can extend life without big upfront premium. Planning site access and permitting early helps avoid delays.
Regional Price Differences
Price variation among regions can be substantial. In the Northeast, higher freight costs and labor rates push total project costs upward. The Midwest typically offers moderate pricing with strong supply chains. The Southwest may see cheaper materials but higher heat-related labor adjustments. For a 350–400 sq ft deck, expect regional deltas of ±10–25% between Urban, Suburban, and Rural markets. Assumptions: region, specs, labor hours.
Labor & Installation Time
Labor cost ties closely to deck size, complexity, and crew efficiency. An average crew might install 25–40 sq ft per day on simple decks. Trex installations often take longer per board due to hidden fasteners and tighter tolerances, while pressure-treated wood can be quicker to assemble but slower to finish with sealants. Labor hours and rates strongly influence total price.
Additional & Hidden Costs
Hidden costs include permits, ground preparation, drainage considerations, and potential structural upgrades if the joist system needs reinforcement. Trex may require additional underlayment or moisture barriers in certain climates. Pressure-treated projects could incur extra costs for sealants, extra coats, or anti-rot finishes. Budget for contingencies and site-specific needs.
Real-World Pricing Examples
Three scenario cards illustrate typical ranges with varying specs. Each includes labor hours, per-unit prices, and totals to help compare Trex and pressure-treated options. Assumptions: region, specs, labor hours.
Scenario Card 1 — Basic (Trex)
Deck size: 320 sq ft; Trex grooved boards; standard hidden fasteners; basic railing. Materials: $2,200; Labor: $1,800; Fasteners: $180; Delivery: $150; Total: $4,330; per sq ft: $13.53. Lower maintenance costs on Trex can offset higher upfront price.
Scenario Card 2 — Mid-Range (Pressure-Treated)
Deck size: 320 sq ft; 2×6 boards; basic railing; sealant. Materials: $1,000; Labor: $1,600; Fasteners: $120; Delivery: $120; Permits: $50; Total: $2,890; per sq ft: $9.03. Lower initial cost but potential resealing and replacement cycles.
Scenario Card 3 — Premium (Trex with Custom Rail)
Deck size: 420 sq ft; Trex capped boards; premium railing; hidden fasteners; curved sections. Materials: $3,000; Labor: $2,600; Delivery: $200; Accessories: $320; Warranty: $60; Total: $6,180; per sq ft: $14.71. Premium features increase both upfront and long-term value.
