Deck Material Comparison: Wood vs. Cedar vs. Composite vs. PVC
Advertisement
The sticker price is the wrong number. A wood deck is half the price of composite on day one — and costs $11,500 more over 25 years. Here's every material compared on installed cost, lifespan, maintenance, and true cost per year of life.
The four materials, side by side
Installed prices, ground-level deck, October 2026 US ranges
| Material | Installed / sqft | Lifespan | Maintenance | $/sqft per year of life |
|---|---|---|---|---|
| Pressure-treated wood | $15–$30 | 10–15 yrs | Stain/seal every 2 yrs (~$1,000/cycle on 400 sqft) | ~$2.64 |
| Cedar / redwood | $22–$45 | 15–20 yrs | Stain/seal every 3 yrs (~$1,200/cycle on 400 sqft) | ~$2.84 |
| Composite (Trex/TimberTech) | $30–$58 | 25–30 yrs | Seasonal wash (~$100/yr supplies) | ~$1.49 |
| PVC / cellular vinyl | $35–$85 | 30–50 yrs | Seasonal wash (~$100/yr supplies) | ~$1.77 |
$/sqft/year = 25-year true cost ÷ 25 ÷ 400 sqft (see the worked example below). Installed ranges: FixUpFirst, HonestCasa, RemodelCalculators, IARemodelings 2026. Maintenance figures are industry estimates — hired staining, not DIY.
25-year true cost: 400-sqft deck, pro install
Standard tier, ground-level, October 2026 prices · straight-line math, no discounting — illustrative
| Cost over 25 years | PT wood | Cedar | Composite | PVC |
|---|---|---|---|---|
| Installed (day one) | $7,200 | $9,400 | $12,400 | $15,200 |
| Maintenance (25 yrs) | $12,000 (stain $1,000/2 yrs) | $9,600 (stain $1,200/3 yrs) | $2,500 (wash $100/yr) | $2,500 (wash $100/yr) |
| Rebuild (at lifespan) | $7,200 (yr 12) | $9,400 (yr 18) | $0 | $0 |
| 25-year total | $26,400 | $28,400 | $14,900 | $17,700 |
The frame is pressure-treated lumber under every material — the price gap is almost entirely the boards. Installed $/sqft used: PT $18, cedar $23.50, composite $31, PVC $38 (midpoints of 2026 ranges). Maintenance cycles are hired-out staining; DIY staining roughly halves those numbers but costs your weekends. Full method: methodology.
The insight nobody advertises: composite costs $5,200 more than wood on day one for a 400-sqft deck — then wood needs $1,000 of staining every two years plus a full rebuild at year 12. Composite's higher sticker price is recovered around year 11, and it finishes 25 years $11,500 cheaper. The "cheap" deck is the expensive one if you stay in the home.
Which material for which yard?
| Your situation | Best pick | Why |
|---|---|---|
| Selling within 7 years | Pressure-treated wood | Lowest upfront cost; you won't own it long enough for maintenance to bite. Remodeling's Cost vs. Value: ~64% ROI on a wood deck addition. |
| Staying 10+ years, hate maintenance | Composite | Wins the 25-year math by $11,500 over wood; no staining ever. |
| Love the natural look, budget for upkeep | Cedar / redwood | The most beautiful deck — but be honest: it's the priciest over 25 years. Budget the staining. |
| Coastal, pool, or "forever home" | PVC | Impervious to moisture, 30–50 year life, best color retention. Highest upfront cost. |
| DIY build | Pressure-treated wood | Most forgiving to cut and fasten; composite needs tighter joist spacing and hidden fasteners. |
Resale reality check
2026 Remodeling Cost vs. Value data (via HonestCasa): a wood deck addition (16×20) averages $17,364 and adds $11,099 in resale value (63.9% ROI); a composite deck addition averages $25,623 and adds $16,533 (64.5% ROI). Buyers value the outdoor space itself — premium materials don't command proportional premiums at resale. Build the deck you'll enjoy; don't overbuild for the appraisal.

What the price range really means: tiers inside each material
The $15–$30 spread on pressure-treated wood isn't noise — it's real product tiers. Here's what sits at the bottom, middle, and top of each range (October 2026 planning estimates).
| Material | Bottom of range | Top of range |
|---|---|---|
| Pressure-treated wood | $15–$20/sqft — basic #2-grade boards, 16" joist spacing | $25–$30/sqft — premium/select boards, 12" joist spacing, hidden fasteners |
| Cedar / redwood | $22–$30/sqft — construction-heart grades with knots | $35–$45/sqft — clear vertical-grain, the showpiece deck |
| Composite | $30–$42/sqft — value lines (uncapped or basic capping) | $45–$58/sqft — premium capped lines with deep grain and 50-yr warranties |
| PVC | $35–$55/sqft — standard colors, basic profile | $60–$85/sqft — multi-tone, heat-reflective, premium profiles |
The tier that matters most is composite's: value-line uncapped composite (~$30–$35/sqft) can stain and fade like a problem child, while premium capped composite (~$50+/sqft) is nearly bulletproof. The mid-range "standard tier" used in the 25-year table ($31/sqft) is capped composite — the sweet spot for most buyers. Framing note: composite needs 12" on-center joists (vs. 16" for wood), which adds roughly $1–$2/sqft to the frame — already reflected in installed prices above.
The extras that move the budget
The deck surface is only part of the project. On a typical 400-sqft build, these line items add up — and they're where "the deck cost $12,000" becomes "the project cost $19,000." Ranges are October 2026 US planning estimates, consistent with our deck cost calculator.
| Extra | Typical cost (2026) | Notes |
|---|---|---|
| Stairs | $50–$100 per step, installed | A 6-step run = $300–$600. Multi-level decks multiply this fast. |
| Railing | $25–$80 / LF installed; cable/glass $80+ | A 16×20 deck needs ~50–60 LF of railing — that's $1,250–$4,800, often the second-biggest line item. |
| Raised / second-story height | ~+30% raised; ~+55% rooftop/2nd story | Industry rule of thumb on the deck-surface price: posts, beams, deeper footings, more labor. |
| Old deck tear-off | $2–$5 / sqft | Disposal included; rotten frames take longer to pull. |
| Permit | $100–$800 | Engineered drawings add $500–$2,500 where required. Anything attached or elevated almost always needs one. |
| Lighting | $50–$200 per fixture, installed | Post-cap lights, stair risers, under-rail strips — plus the electrical run. |
| Pergola or roof structure | $3,500–$15,000+ | Needs its own footings and engineering; don't price it as "a few posts." |
Height multipliers (+30% raised, +55% rooftop/second-story) are industry rules of thumb, labeled as estimates. On small elevated decks, railing + stairs can rival the deck surface itself — always price the whole project, not just the boards.
Two worked examples
300-sqft pressure-treated deck, ground level (Ohio)
Surface at $22/sqft (mid-range): 300 sqft = $6,600. Add 4 steps ($75 × 4 = $300), 45 LF of wood railing ($40/LF = $1,800), and a permit ($250). All-in: ~$8,950 — planning estimate ±25%. The railing is 20% of the project; cutting railing footage (a lower deck may not need it on all sides) is the biggest single lever.
400-sqft composite deck, raised 4 ft with railing (Colorado)
Surface at $31/sqft: 400 sqft = $12,400. Raised height adds ~+30% on the surface = $3,720. Add 6 steps ($450), 60 LF of composite railing ($45/LF = $2,700), and a permit ($400). All-in: ~$19,670. Same material, but height + railing + stairs add ~60% over the bare surface — the classic budget surprise. Budgeting estimate, not a quote.
Never budget "deck material × square feet" and stop. Stairs, railing, height, and the permit routinely add 40–70% on top of the surface number. Run the full scope through the deck cost calculator before you fall in love with a material.
Climate notes: pick for your weather
- Sun belt (AZ, TX, FL): UV and heat are the killers. Composite gets hot underfoot — choose light colors or heat-reflective PVC lines. Wood needs staining every 18–24 months here, not every 2–3 years.
- Snow country (upper Midwest, New England): Freeze-thaw cycles punish wood joints and cheap composite. Footings below the frost line (36–48") are code, not optional. PVC shrugs off ice-melt chemicals best.
- Wet / Pacific Northwest: Constant moisture rots wood fast — use ground-contact-rated lumber or skip wood entirely. Composite and PVC thrive here; ensure good under-deck drainage.
- Coastal: Salt air corrodes standard fasteners — stainless or coated fasteners are mandatory regardless of board material. PVC and capped composite handle salt best.
Deck material FAQs
What is the cheapest deck material in 2026?
Pressure-treated wood: $15–$30/sqft installed. But over 25 years it's the most expensive option (~$26,400 on 400 sqft with staining and a rebuild) vs. composite (~$14,900). Cheapest day one ≠ cheapest over time.
How long does a composite deck last vs. wood?
Composite: 25–30 years (some lines warrantied to 50). Pressure-treated wood: 10–15 years with diligent staining. Cedar: 15–20 years. PVC: 30–50 years.
Does composite decking get hot?
Yes — especially dark colors in direct sun, noticeably hotter than wood underfoot. Lighter colors and PVC's heat-reflective lines help. It's the most common complaint about composite after price.
Can I put composite boards on my existing wood frame?
Sometimes — if the frame is sound, level, and the joist spacing meets the composite's span rating (usually 12" on-center vs. 16" for wood). Have a pro inspect the frame first; a rotted frame under new boards is money wasted.
How much does a 12×12 deck cost in 2026?
A 144-sqft ground-level deck: pressure-treated wood ~$2,200–$4,300 for the surface, composite ~$4,300–$8,400. Add railing (often required above 30" high — budget $25–$80/LF), stairs ($50–$100/step), and a permit ($100–$800). Realistic all-in for a basic wood 12×12 with railing: ~$4,000–$7,000; composite: ~$7,000–$12,000. Planning estimates, not quotes.
Can you stain or paint composite decking?
You shouldn't need to — and manufacturers generally advise against it, since paint and stain don't bond well to the capped polymer shell and can void the warranty. If a composite deck is faded beyond tolerance, check the fade warranty first; some lines cover excessive fading for 20+ years. For uncapped first-generation composite that's grayed out, a composite-specific restorer is the only finish worth trying.
Is composite decking slippery when wet?
It can be — smooth, uncapped composite is the worst offender, and algae growth in shade makes any deck slick. Capped composite with embossed wood grain has meaningfully better wet traction, and PVC lines marketed as "barefoot-friendly" tend to grip best. In rainy climates, choose textured profiles and keep the deck washed; anti-slip strips exist but look aftermarket.
Should I DIY or hire a pro for a composite deck?
Composite is less DIY-forgiving than wood: it needs 12" joist spacing, hidden fastener systems, precise gapping for thermal expansion, and careful cutting (it chips). A first-timer can do a small ground-level rectangle with patience; anything raised, multi-level, or with complex railing deserves a pro. The labor you save (~30–40% of the project) is real money, but framing mistakes on an elevated deck are structural — when in doubt, hire the frame and DIY the finish work.
