Wood vs. composite decking — upfront cost, maintenance, lifespan, and which delivers more long-term value.

Decking is one of the most debated material choices in home improvement. Pressure-treated wood is the traditional standard — cheap, strong, and universally available. Composite decking (Trex, Fiberon, TimberTech) entered the market as a premium alternative. Today, composite outsells wood decking in many markets. The reason comes down to maintenance math.

## Pressure-Treated Wood: Low Entry Cost, High Maintenance

Pressure-treated pine is the most affordable decking option at **$15–$25 per sq ft installed**. It's structurally strong and holds fasteners well. But PT wood requires annual sealing or staining to prevent splitting, graying, and rot — and if neglected even for 2–3 years, it deteriorates noticeably. A PT deck that's properly maintained can last 15–25 years; one that isn't may need significant repair or replacement in 10.

## Composite Decking: Higher Upfront, Lower Lifetime Cost

Premium composite decking (Trex Transcend, TimberTech Azek) runs **$35–$60 per sq ft installed**. It requires no staining, no sealing, and no annual maintenance beyond occasional washing. Most premium composite lines carry 25–30 year fade and stain warranties. Over a 25-year period, the maintenance cost savings on a 400 sq ft deck (staining every 2–3 years at $300–$600) can close a significant portion of the upfront premium gap.

| Factor | Composite Decking | Pressure-Treated Wood |
| --- | --- | --- |
| Installed Cost (per sq ft) | $35–$60 | $15–$25 |
| Annual Maintenance | Wash occasionally | Seal/stain every 1–3 years |
| Lifespan | 25–30+ years (warrantied) | 15–25 years (if maintained) |
| Splinters / Warping | No | Yes (especially if neglected) |
| Fade/Stain Warranty | 25–30 years (premium products) | None |
| Resale Appeal | High — low-maintenance selling point | Expected standard |
| Best For | Long-term owners, low-maintenance preference | Tight budget, shorter ownership horizon |

Bottom Line

Composite decking wins on lifetime value for homeowners staying 10+ years — the maintenance savings close the upfront gap. Pressure-treated wood is the right call for tight budgets or shorter ownership horizons. Never skip the PT wood sealing schedule.[Get Exterior Quotes →](https://offers.remodelyourhome.com/roofing/simple)
