Homeowners commonly pay for decking with two main options: cedar and composite. The overall cost is driven by material choice, area to cover, labor, and add-ons such as railing and fasteners. This article outlines typical price ranges and the main cost drivers to help builders choose based on budget and long-term value.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material ( Cedar ) | $2.50/sq ft | $4.00/sq ft | $6.50/sq ft | Natural wood, maintenance varies |
| Material ( Composite ) | $4.50/sq ft | $7.50/sq ft | $9.50/sq ft | Mid-range to premium brands |
| Installation Labor | $3.50–$6.50/sq ft | $5.50–$9.00/sq ft | $9.00+/sq ft | Includes framing and fastening |
| Fasteners & Accessories | $0.50–$1.50/sq ft | $1.00–$2.50/sq ft | $3.00+/sq ft | Hidden fasteners, trim, flashing |
| Sealing/Finishing (cedar) | $0.50–$1.00/sq ft | $0.80–$1.50/sq ft | $2.00+/sq ft | Oil or sealant every 1–2 years |
Overview Of Costs
Cost ranges show total project pricing and per-unit pricing. For a typical 300 sq ft deck, cedar material totals usually fall in the $1,650–$4,500 range, while composite materials often run $2,250–$4,500. Labor for framing and installation commonly adds $1,650–$4,500. In total, a cedar deck might cost $3,300–$9,000, and a composite deck $3,900–$9,000, depending on boards, fasteners, and added features.
Assumptions: region, deck size, slope, and crew hours affect totals; costs exclude structure permits in some areas. Assumptions: region, specs, labor hours.

Cost Breakdown
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty |
|---|---|---|---|---|---|
| Cedar boards, spacers, fasteners | 3–6 hours per 100 sq ft | Miter saw, nailer | Varies by locality | Delivery included in some quotes | Wood warranty typically 1–5 years |
| Composite boards, hidden fasteners | 4–8 hours per 100 sq ft | Power tools, saw blades | Building permit if required | Delivery often separate | Warranty often 25 years |
What Drives Price
Material type is the primary variable. Cedar costs are tied to lumber grade, wood species, and density; maintenance costs accumulate over time. Composite decking price depends on brand, cap-stock technology, and color options. For both, deck size, design complexity, and substrate preparation influence totals. Regional labor rates and local permit requirements add notable variance.
Two niche drivers worth noting: hardwood decking with higher pitch or steep stairs increases install time; and composite brands with high-performance finishes may require specialized tools and longer cutting cycles, influencing per-square-foot labor costs.
Factors That Affect Price
Installation time and crew size significantly impact total cost. A simple rectangle may need fewer labor hours than a multi-level or curved design. Cedar often requires sealing every 1–2 years, adding ongoing costs beyond initial install. Composite decks reduce maintenance but may incur higher upfront material costs and sometimes more expensive hidden fasteners.
Ways To Save
Compare deck sizes and layout complexity to identify savings opportunities. Choosing cedar with standard 5/4 boards instead of wide-slat options can reduce material costs. If longevity matters more, investing in a premium composite might save sealing and staining expenses over time. Contractors frequently offer volume discounts on materials for larger projects.
Regional Price Differences
Prices diverge by region due to labor markets and supply chains. In the Northeast, expect higher material costs due to shipping and demand, while the South may show lower permit-related expenses. Rural areas often have lower labor rates but higher delivery charges. For a 300 sq ft deck, regional deltas can swing totals by ±15–25% depending on materials and crew availability.
Labor, Hours & Rates
Labor rates commonly range from $40–$70 per hour in many markets, with skilled carpenters commanding $60–$90 per hour for complex installations. A typical cedar deck may require 70–120 labor hours for mid-size work, while a composite deck with hidden fasteners and railing can push toward 120–180 hours. Higher complexity raises costs quickly.
Additional & Hidden Costs
Hidden surcharges can come from permits, demolition of old decking, drainage work, or required footings. Some regions add sales taxes on materials; others apply tax-exempt status for contractors. If moisture barriers and flashing are needed, expect added line items. Budget for contingencies of 5–10%.
Real-World Pricing Examples
Sample quotes illustrate typical ranges for a 300 sq ft project with cedar versus composite:
- Basic Cedar Deck: Cedar boards, standard 2×6 framing, no railings; 70 hours labor; materials $1,600; labor $3,000; total $4,600.
- Mid-Range Composite Deck: Cap-stock boards, hidden fasteners, railing kit; 110 hours labor; materials $3,000; labor $5,000; total $8,000.
- Premium Composite with Wide Railing: Premium boards, aluminum rails, extra flashing; 150 hours labor; materials $4,300; labor $6,800; total $11,100.
Notes: prices assume standard backyard installation, 6–8 ft tall railing, and flat substructure. Assumptions: region, specs, labor hours.
Maintenance & Ownership Costs
Long-term value often favors composite for lower maintenance. Cedar requires periodic sealing every 1–2 years and possible wood repairs from weathering. Composite decks generally avoid staining but may need occasional cleaning and board replacement if stained or scratched. A 5-year cost outlook shows cedar maintenance can add 10–25% of initial price, while composites may stabilize and reduce annual upkeep.
Price At A Glance
For a 300 sq ft deck, cedar price ranges commonly fall between $3,300–$9,000 inclusive of materials and basic labor; composite price ranges commonly fall between $3,900–$11,000 with higher-end finishes. Local market conditions and project specifics determine exact outcomes.
