Wood vs Composite Deck: Which Is Better? (2026)
Quick answer: wood decks cost less upfront ($3–$8/sq ft) but need staining every 2–3 years and last 10–15 years; composite costs more ($8–$14/sq ft) but needs almost no maintenance and lasts 25–30 years. Choose wood for the lowest first cost, composite if you never want to stain again.

Wood vs composite: head-to-head
| Factor | Pressure-treated wood | Composite |
|---|---|---|
| Board cost / sq ft | $3–$8 | $8–$14 |
| Installed / sq ft | $6–$12 | $15–$25 |
| Lifespan | 10–15 yrs | 25–30 yrs |
| Maintenance | Stain every 2–3 yrs | Wash occasionally |
| Rot / splinters | Can rot, warp, splinter | Resists all |
| Color retention | Fades, needs restain | Fades slowly, no stain |
| Comfort underfoot | Cooler in sun | Can get hot in direct sun |
Lifespan & true cost over time
The sticker price hides the real math. A wood deck needs restaining roughly every 2–3 years (materials ~$100–$300 per job, plus labor if hired) and board replacement after 10–15 years. Composite lasts 25–30 years with little upkeep. Over a 30-year window:
- Wood: ~$9,000 initial + ~3 staining cycles + full rebuild at year ~15 ≈ often more than composite in the long run.
- Composite: ~$18,000 initial, one installation, minimal upkeep for 25–30 years.
If you plan to stay long-term, composite frequently wins on lifetime cost; if you're selling soon or want the lowest first bill, wood is hard to beat.
Maintenance
This is the deciding factor for most people. Wood needs power-washing and restaining every 2–3 years, checking for warped or rotting boards, and occasional screw-tightening. Composite needs only an occasional wash with soap and water — no staining, no sealing, no splinters. If you'd rather spend weekends using the deck than maintaining it, composite is worth the premium.
Appearance & comfort
Wood has a natural warmth many people prefer, and it's cooler underfoot in direct sun. Composite mimics wood with grooved, textured boards and holds its color longer, but dark composite can get noticeably hot in full sun — worth considering on uncovered, south-facing decks. Both come in many styles, so the choice is more about budget and maintenance tolerance than looks.
Worked example: a 12×12 deck
- Area = 12 × 12 = 144 sq ft
- Wood boards (pressure-treated) ≈ $700–$1,100
- Composite boards ≈ $1,200–$2,000
- Joists/framing are similar either way — roughly the same support structure
- Installed totals: wood ~$1,000–$1,700, composite ~$2,200–$3,600
FAQ
Composite costs more upfront ($8–$14/sq ft versus $3–$8 for wood) but needs almost no maintenance and lasts 25–30 years, versus wood's 10–15 years plus staining. Over the long run composite is often the better value.
Quality composite decking typically lasts 25–30 years and won't splinter or rot. Pressure-treated wood lasts roughly 10–15 years before boards need replacing, with staining needed every 2–3 years.
Both handle normal deck loads if framed correctly. Composite resists rot, splinters, and moisture better and holds its color longer; wood is stronger point-for-point but rots and warps without maintenance.
Yes, composite boards install with hidden or standard clips on the same joist framing as wood. It's heavier and requires specific clips and expansion gaps, but a competent DIYer can manage a straightforward deck.
