Composite vs. Wood Decking
Composite decking costs more upfront but requires minimal maintenance over its life. Pressure-treated wood starts cheaper but needs regular staining and sealing to hit its rated lifespan. The real comparison is total cost over 20+ years, not just the day-one material bill.
Bottom line
Composite wins on total lifecycle cost for owners who stay put 15+ years. Wood wins on day-one cost and flexibility — as long as you commit to the maintenance schedule.
How they compare
| Category | 🟫 Composite Decking | 🪵 Wood Decking |
|---|---|---|
| Upfront material cost | Higher | Lower |
| Lifespan | 25–30 years | 15–20 years with regular staining |
| Annual maintenance | Wash once per year | Sand and stain every 2–3 years |
| Splinters | None | Possible as boards age |
| DIY difficulty | Moderate (heavier boards) | Easier (lighter boards, standard cuts) |
| Fading/staining | Fade-resistant (UV inhibitors built in) | Grays and silvers without regular staining |
| Surface lamination | Capped composite has a polymer shell — resists stains, mold, and moisture | Raw wood — must be sealed; still checks and weeps over time |
Pros and cons
🟫 Composite Decking

🪵 Wood Decking
- ✓Lower initial material cost
- ✓Can be painted or stained any color at any time
- ✓Works with standard circular saw blades
- ✓Cooler underfoot in direct sun
- ✕Requires staining and sealing every 2–3 years
- ✕Can splinter and develop surface checks over time
- ✕Shorter lifespan without consistent upkeep
- ✕Susceptible to rot if water pools underneath
When to choose each
Choose Composite Decking
