Composite vs Wood DeckingWhich Is Better?
A comprehensive comparison of composite and wood decking materials to help you choose the right option for your budget, climate, and lifestyle.
Quick Answer
Choose composite decking if you want minimal maintenance, 25-50 year lifespan, and consistent appearance over time. Choose wood (pressure-treated or cedar) if upfront budget is your primary concern, you enjoy the natural look and feel of real wood, and you are willing to maintain it annually. Composite costs 2-4x more upfront but saves money over 20+ years when you factor in staining, sealing, and replacement costs for wood.
What Is Composite Decking?
Composite decking is an engineered building material made from a combination of wood fibers (sawdust, wood flour) and plastic polymers (typically polyethylene or polypropylene). The wood fibers provide structural rigidity and a natural appearance, while the plastic component delivers moisture resistance and durability. Most modern composite boards feature a protective polymer cap (shell) on all four sides that resists staining, fading, mold, and scratching.
Major composite decking brands include Trex (the market leader, using 95% recycled materials), TimberTech/AZEK (offering both composite and PVC options), Fiberon, Deckorators, and MoistureShield. Prices range from $4 to $12 per linear foot for the boards alone, with most homeowners choosing mid-range products at $6 to $8 per linear foot. Composite boards are typically available in 12, 16, and 20-foot lengths and 5.5-inch or 7.25-inch widths.
What Is Wood Decking?
Wood decking uses natural lumber boards as the deck surface. The three most common wood species for decking are pressure-treated southern yellow pine (the most affordable and widely available), western red cedar (naturally rot-resistant with a warm tone), and tropical hardwoods like ipe, cumaru, and tigerwood (the most durable but most expensive). Pressure-treated pine accounts for roughly 75% of all wood decks built in the United States.
Pressure-treated deck boards cost $1.50 to $3.00 per linear foot, making them the most budget-friendly decking option. Cedar ranges from $3.00 to $5.00 per linear foot, while tropical hardwoods run $5.00 to $12.00 per linear foot. Wood deck boards are available in 8, 10, 12, 16, and 20-foot lengths. The standard deck board is a 5/4x6 (actual 1 inch thick by 5.5 inches wide), which provides good stiffness and comfort underfoot.
Composite vs Wood: Side-by-Side Comparison
How the two materials stack up across every important category.
| Category | Composite Decking | Wood Decking |
|---|---|---|
| Upfront Cost (per sq ft) | $8-$22 installed | $4-$12 installed |
| Lifespan | 25-50 years | 10-30 years (varies by species) |
| Annual Maintenance | Soap and water wash | Stain/seal every 1-2 years |
| Maintenance Cost (20 yr) | $0-$200 total | $2,000-$5,000 total |
| Appearance | Consistent, manufactured look | Natural grain, ages to gray |
| Heat Retention | Gets very hot in sun | Stays cooler underfoot |
| Scratch Resistance | Good (capped products) | Varies by species |
| Fade Resistance | Excellent (25-yr warranty) | Grays without maintenance |
| Environmental Impact | Recycled content, long life | Renewable, shorter life |
| DIY Difficulty | Moderate (special fasteners) | Easy (standard screws) |
Cost Comparison: The Full Picture
The upfront price difference between composite and wood is significant, but the total cost of ownership over the deck's lifetime tells a different story.
For a typical 12x16-foot deck (192 sq ft), pressure-treated wood decking material costs $600 to $900 for the boards alone. The same deck in mid-range composite (Trex Select or TimberTech Edge) costs $1,500 to $2,400 for boards. Including the substructure, fasteners, and installation labor, the total installed cost is approximately $3,000 to $5,000 for wood and $5,500 to $9,000 for composite.
However, wood decks require annual maintenance. Staining and sealing a 192 sq ft deck costs $150 to $400 per year in materials (quality exterior stain plus application supplies). Over 20 years, that is $3,000 to $8,000 in maintenance costs alone. A pressure-treated deck also typically needs board replacement after 12 to 15 years ($1,000 to $2,000). Composite decks need only occasional soap-and-water cleaning.
Over a 25-year period, the total cost of ownership for a 12x16 wood deck is approximately $7,000 to $15,000 (initial build plus maintenance and partial replacement). The same composite deck costs $5,500 to $9,000 total with virtually zero maintenance expense. At the 15 to 20-year mark, composite becomes the more economical choice.
When to Choose Composite Decking
Composite decking is the better choice in these situations:
- You want a low-maintenance deck that never needs staining, sealing, or painting.
- You live in a humid, rainy, or coastal climate where wood decays quickly.
- You plan to stay in the home for 10+ years and want long-term value.
- You prefer a consistent, uniform appearance that will not change over time.
- You want a 25 to 50-year manufacturer warranty for peace of mind.
- You are building a second-story or hard-to-access deck where maintenance would be difficult.
Composite is the best all-around choice for homeowners who prioritize convenience, durability, and long-term savings over the lowest possible upfront cost.
When to Choose Wood Decking
Wood decking makes more sense in these situations:
- Your upfront budget is limited and you need to minimize initial construction cost.
- You love the natural look, feel, and scent of real wood and are willing to maintain it.
- You live in an extremely hot climate where composite would be uncomfortably hot underfoot.
- You are building a temporary or short-term structure (5 to 10 year horizon).
- You enjoy DIY maintenance projects and view annual staining as a satisfying ritual.
- You want a tropical hardwood deck (ipe, cumaru) that offers both natural beauty and 25+ year durability.
Wood is ideal for budget-conscious builders, natural-wood enthusiasts, and projects where the warmth and character of real wood outweigh the maintenance commitment.
