Homeowners typically pay a mix of material costs and installation fees when choosing between Trex composite decking and cedar. The main cost drivers are material type, board thickness and width, hidden-fastener needs, railing choices, and labor time for installation. This guide compares pricing, breaks down components, and highlights savings opportunities for U.S. buyers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (Decking boards, rails, fasteners) | $2.50/sq ft | $6.50/sq ft | $12.50/sq ft | TREX typically higher; Cedar lower depending on species |
| Labor & Installation | $4.00/sq ft | $8.50/sq ft | $16.50/sq ft | Labor varies by complexity and region |
| Permits & Inspections | $0 | $200 | $800 | Region-dependent |
| Delivery/Disposal | $100 | $350 | $900 | Material volume dependent |
| Warranty & Extras | $0 | $250 | $900 | TREX often includes longer manufacturer warranty |
Overview Of Costs
Cost ranges reflect deck area, material selection, and installation complexity. Trex composite decking costs higher upfront but can reduce maintenance over time, while cedar offers a lower initial price with more frequent upkeep. Typical project ranges assume a mid-size, flat residential deck with standard railing and basic stairs.
Cost Breakdown
The following table outlines common cost components for Trex and Cedar decks, with totals and per-unit figures.
| Component | TREX (Composite) | Cedar | Notes |
|---|---|---|---|
| Materials (boards + rails) | $3.50-$9.50 / sq ft | $2.00-$5.50 / sq ft | Trex often requires hidden fasteners |
| Labor & Installation | $4.00-$9.50 / sq ft | $3.50-$7.50 / sq ft | Complex profiles raise labor time |
| Permits & Inspections | $0-$800 | $0-$800 | Depends on locality |
| Delivery/Disposal | $100-$600 | $50-$500 | Volume and distance matter |
| Warranty & Extras | $0-$900 | $0-$700 | TREX often comes with extended warrantied options |
Factors That Affect Price
Material specifications drive cost: composite boards often use thicker cores and protective caps that raise price, while cedar pricing depends on species (Eastern, Western red cedar) and grade. Assumptions: region, deck size, rail style.
Regional Price Differences
Prices vary by geography. In the Northeast, install labor tends to be higher, while the Southeast may see lower rates due to milder climates. In urban markets, material premiums and delivery charges can push costs higher compared with rural areas. Trex pricing tends to stay within a narrower band, but cedar can swing more with local timber availability.
Labor, Hours & Rates
Labor rates commonly range from $35 to $85 per hour depending on crew experience and market demand. Labor time grows with deck size, complexity (stair cases, curves), and railing systems. Complex railing or built-in features add to both material needs and labor hours.
Additional & Hidden Costs
Hidden costs may include ground prep, footings, soil removal, drainage adjustments, and sealants or finishes for cedar decks. Trex may require specialized cleaners or minimal maintenance products to preserve warranty terms. Assumptions: basic ground conditions, standard footings.
Real-World Pricing Examples
Three scenario cards illustrate typical price outcomes for Trex and cedar installations.
-
Basic – 250 sq ft deck, straight boards, standard railing, minimal drainage work.
Assumptions: region, standard specs, 60 hours total.- TREX: Materials $2.75/sq ft, Labor $5.25/sq ft, Subtotal $2,000–$4,000
- Cedar: Materials $1.50/sq ft, Labor $4.50/sq ft, Subtotal $1,100–$2,600
-
Mid-Range – 400 sq ft with upgraded railing and stairs.
Assumptions: region, mid-grade materials, 110 hours total.- TREX: Materials $4.00-$8.50/sq ft, Labor $6.00-$9.50/sq ft, Subtotal $5,600–$12,100
- Cedar: Materials $2.00-$4.75/sq ft, Labor $4.50-$7.50/sq ft, Subtotal $3,600–$8,300
-
Premium – 600 sq ft with custom cuts, integrated lighting, premium railing.
Assumptions: urban market, high-end features, 180+ hours total.- TREX: Materials $5.00-$11.00/sq ft, Labor $8.00-$12.50/sq ft, Subtotal $13,200–$28,500
- Cedar: Materials $2.50-$6.00/sq ft, Labor $6.00-$10.50/sq ft, Subtotal $7,800–$17,700
Maintenance & Ownership Costs
TREX typically incurs lower ongoing maintenance costs—occasional cleaning and sealant is rarely required, and stainings are usually unnecessary. Cedar decks require periodic sealing, staining, and treatments to maintain color and resistance. 5-year cost outlook shows Trex staying steadier as cedar upkeep ramps up over time.
Price By Region
Regional price differences reflect material transport, labor markets, and permit costs. In the Pacific Northwest, higher timber costs can narrow the cedar price gap, while Midwestern markets may offer competitive cedar pricing due to local sawmills. Trex price tends to align with national averages across regions.
Permits, Codes & Rebates
Local rules may require deck permits, especially for larger or elevated projects. Some regions offer rebates or tax incentives for low-maintenance materials or energy-related improvements. Include permit fees in the planning budget to avoid delays. Assumptions: local policy varies.
Budget Tips
- Compare total installed price rather than per-sq-ft alone to capture labor differences.
- Consider hidden costs like footings, drainage, and railing options when estimating.
- Ask for material warranties and maintenance recommendations to estimate long-term costs.
- Consider rough-in timelines to take advantage of off-peak installation discounts in shoulder seasons.
Assumptions: region, specs, labor hours.
