When you're planning a new deck, the material choice will make or break your budget and maintenance routine for the next 20 years. Both wood and composite have genuine trade-offs that aren't just about upfront cost. Here's what you actually need to know to make the right call for your home and lifestyle.
Initial Installation Costs
Wood decking typically runs $15–$25 per square foot for materials alone, with pressure-treated lumber being the cheapest option and cedar or ipe commanding premium prices. Composite decking costs $25–$50 per square foot for materials, roughly double what pressure-treated wood costs, though high-end composites can exceed that range.
Labor charges from deck builders usually range $50–$100 per hour and don't vary significantly between materials—the time to frame, install, and finish is similar. A 400-square-foot deck might run $3,000–$5,000 total for a basic wood build versus $6,000–$10,000 for composite, depending on your location and deck complexity.
Long-Term Maintenance and Replacement Costs
This is where wood and composite truly diverge. Wood requires staining or sealing every 2–3 years at a cost of $0.50–$2 per square foot each time. Without regular maintenance, wood deteriorates fast—you're looking at board rot, splintering, and structural damage within 5–10 years of neglect.
Composite decking requires minimal upkeep: occasional cleaning and maybe a refresh coat of sealer every 5–7 years, totaling $150–$500 over the deck's lifetime for a typical residential deck. That low maintenance cost saves money and stress year after year.
Lifespan and Real Replacement Scenarios
Pressure-treated wood decks typically last 10–15 years with proper maintenance, or 5–8 years if neglected. Cedar and other premium woods can stretch to 15–20 years but demand consistent care.
Composite decks commonly last 25–30 years, with many manufacturers offering 25-year warranties against fading and staining. After 25 years, composites may show cosmetic wear but usually remain structurally sound.
If you plan to stay in your home for 20+ years and dislike outdoor maintenance, composite breaks even financially around year 10–12, then becomes genuinely cheaper over time.
Key Differences Beyond Cost
| Factor | Wood | Composite | |--------|------|-----------| | Appearance | Warm, natural feel; ages visibly | Consistent color; looks similar for years | | Safety | Can splinter; gets slippery when wet | No splinters; better grip surface | | Environmental impact | Renewable but often pressure-treated with chemicals | Recycled materials common; no chemical treatment needed | | Repair | Individual boards easily replaced | Harder to match color if patching years later | | Heat absorption | Stays cooler underfoot | Gets hotter in direct sun (notable in southern climates) |
What to Ask Your Deck Builder
When getting quotes, specify whether you want pressure-treated, cedar, or composite—don't let builders assume. Ask how they handle:
- Substructure and drainage: Poor framing ruins both materials quickly.
- Warranty terms: What does the builder warranty, and for how long?
- Maintenance expectations: Get their honest assessment of what you'll actually need to do each year.
- Local climate suitability: Builders in humid regions may steer you toward composite for mold resistance; those in dry climates often favor wood.
Making Your Decision
Choose wood if you enjoy outdoor maintenance, prefer natural aesthetics, and plan to stay under 12 years, or if budget is extremely tight upfront.
Choose composite if you want hands-off durability, value a consistent look, live in a humid climate, or plan to enjoy the deck for 20+ years without stress.

Frequently Asked Questions
Q: Will composite really save me money compared to wood long-term? Yes, typically after 10–12 years of ownership, composite becomes cheaper overall when accounting for staining, sealing, and repairs that wood requires. After 20 years, composite savings can reach $2,000–$4,000 depending on material choices.
Q: Can I mix wood and composite on the same deck? Absolutely—many builders use composite for the deck surface (high wear area) and wood for framing or railings to reduce overall cost while keeping the most-visible area low-maintenance.
Q: How do I know if a contractor is experienced with my chosen material? Ask to see photos of completed decks using that material and request references from homeowners at least 3–5 years past installation—they'll give honest feedback on how well it held up.
