Composite vs Wood Decking
A complete side-by-side comparison to help you choose the right decking material for your project.
Last updated: May 2026
| Factor | Composite | Wood (Pressure-Treated) |
|---|---|---|
| Cost per Sq Ft | $8–$15 | $2–$5 |
| Lifespan | 25–50 years | 10–15 years |
| Maintenance | Virtually none (wash only) | Stain/seal every 2–3 years |
| Appearance | Uniform, many colors | Natural wood grain |
| Heat Retention | Gets hot in sun | Stays cooler |
| Scratch Resistance | Can scratch, hard to repair | Can sand out scratches |
| Rot & Insect Resistance | Immune | Treated but can still rot |
| Eco-Friendly | Made from recycled materials | Chemical treatment process |
| DIY Difficulty | Easy (hidden fasteners) | Easy (standard screws) |
| Warranty | 25–50 year manufacturer | Limited or none |
Cost Comparison
Wood decking wins on upfront cost — pressure-treated pine runs $2–$5 per square foot for materials, while composite ranges from $8–$15. For a typical 12×16 ft deck (192 sq ft), that's roughly $580–$960 for wood vs $1,540–$2,880 for composite in materials alone. However, factoring in maintenance costs over 20 years (staining every 2–3 years at $200–$500 per application), wood's total cost approaches composite's. Over 25+ years, composite often costs less overall.
Composite Decking: Pros & Cons
Pros
- No staining, sealing, or painting ever
- Won't rot, warp, or splinter
- Immune to termites and insects
- 25–50 year manufacturer warranty
- Made from recycled materials
- Consistent color throughout
Cons
- 2–3× higher upfront cost
- Gets hotter in direct sunlight
- Can look artificial up close
- Scratches are hard to repair
- Heavier than wood (harder to work with)
- Can develop mold in shady, damp areas
Wood Decking: Pros & Cons
Pros
- Much lower upfront cost
- Natural look and feel
- Stays cooler in sun than composite
- Easy to cut, sand, and repair
- Can be refinished to look new
- Widely available at any lumber yard
Cons
- Requires staining/sealing every 2–3 years
- Can rot, warp, crack, and splinter
- Vulnerable to termites without treatment
- Shorter lifespan (10–15 years)
- Fades and grays without maintenance
- Higher total cost of ownership over 20+ years
Which Should You Choose?
Choose Composite If:
- You want a "build it and forget it" deck with minimal upkeep
- You're planning to stay in the home long-term (10+ years)
- Your budget allows for the higher upfront investment
- The deck is in a shaded area (less heat concern)
Choose Wood If:
- You're working with a tight budget
- You prefer the natural look and feel of real wood
- You don't mind annual maintenance
- You may sell the home within 5–10 years

Composite is the better choice for most homeowners who plan to keep their deck long-term: it lasts 25–50 years with virtually no maintenance, never needs staining or sealing, and is immune to rot and insects. Wood is better if upfront cost is the priority or you prefer the look and feel of real lumber. Neither is universally better — composite wins on longevity and upkeep, while wood wins on price, natural appearance, and staying cooler in the sun.
Composite decking costs $8–$15 per square foot for materials, versus $2–$5 for pressure-treated wood — roughly 2–3 times more upfront. For a typical 12×16 ft deck (192 sq ft), that works out to about $1,540–$2,880 for composite versus $580–$960 for wood. However, wood needs staining or sealing every 2–3 years at $200–$500 per application, so over 20–25 years the total costs converge and composite often ends up cheaper.
Composite decking lasts significantly longer: 25–50 years, backed by 25–50 year manufacturer warranties. Pressure-treated wood decking typically lasts 10–15 years, and even with diligent staining and sealing it will eventually rot, warp, or splinter. A single composite deck can easily outlast two or three wood decks.
