Is Composite Decking Worth the Cost? ROI vs Pressure-Treated Wood

The question every homeowner faces: pay more upfront for composite or save now with pressure-treated wood? Here's the data-driven answer based on total cost of ownership.

20-Year Total Cost of Ownership

A pressure-treated deck costs roughly $23,000–$26,000 over 20 years when you account for staining every 2–3 years ($300–$450 per session DIY) and full replacement at year 12–15. An entry-level composite deck like Trex Enhance or Fiberon Good Life costs $11,000–$13,500 over 20 years — roughly half the total cost of wood, even though the upfront price is similar or slightly higher. Premium composite like Trex Transcend or TimberTech Legacy costs more upfront but still beats wood on 20-year total cost.

Resale Value

According to Remodeling Magazine's 2025 Cost vs. Value Report, wood deck additions recover 66.8% of cost at resale while composite recovers 54.2%. Wood wins on percentage because it starts cheaper, but in absolute dollars, composite adds more to home value ($13,131 vs $11,390). Real estate agents report that composite decks are increasingly expected by buyers in the $400K+ home range.

Maintenance Time

Pressure-treated wood: 15–25 hours per year (annual washing, staining every 2–3 years, spot repairs). Composite: 2–5 hours per year (sweeping, twice-yearly wash). If you value your time at $50/hour, the 20-year maintenance savings alone are worth $12,000–$20,000 for composite.

Climate Factors Favoring Composite

High humidity (wood warps and rots faster), wildfire zones (PVC offers Class A fire ratings), poolside (PVC is 100% waterproof), and coastal areas (salt air accelerates wood decay) — all these conditions favor composite or PVC over pressure-treated wood.

When Wood Still Makes Sense

Short ownership (selling in 3–5 years), rental properties, and strict upfront budgets where the choice is a small wood deck vs no deck at all. Wood's lower entry price can make sense when cash flow is the primary constraint.

The Verdict

Composite decking is worth the cost if you plan to stay 7+ years, value your weekends, and can handle the $1,500–$5,000 upfront premium. The break-even point is typically year 7–10, when cumulative wood maintenance costs surpass the initial composite premium. After that, composite is pure savings.
