Composite Decking vs Wood Decking | Materials Compared for 2026

If you’re planning a new deck, the material choice drives every other decision — cost, time spent maintaining it, and how long it lasts before needing replacement. Composite and wood serve the same purpose but work very differently once installed. Here’s what each actually costs and delivers, so you can match the right material to your situation.

What Each Material Is Made Of

Composite decking blends wood fibers with recycled plastic, or uses 100% PVC (synthetic). Wood decking means pressure-treated lumber, cedar, redwood, or tropical hardwoods like Ipe. The composition difference is what creates the maintenance gap: composite resists rot, insects, and moisture by design; wood requires chemical treatment or natural oils to do the same, and those protections wear down over time.

Composite boards resist warping, cracking, and splintering, and they’re termite-proof. Wood splits, weathers, and attracts pests unless it’s sealed regularly. But wood can be repaired — sand a damaged spot and re-stain next season — while composite damage is permanent. If you move heavy furniture around, wood generally holds up better to that kind of wear.

Which One Costs Less Today — And Over Time

Wood wins on upfront price. Pressure-treated lumber runs $3–$6 per square foot in materials; cedar and redwood run $7–$12. A 300-square-foot wood deck installed costs roughly $3,300–$6,000.

Composite material pricing starts at about $5 per square foot for entry-level lines and goes up to $15 or more for premium capped products. Installed, a 12×12 composite deck runs from roughly $6,500 on the low end to over $10,500 for a premium line like Trex Transcend. Labor nationally adds $10–$20 per square foot, with higher rates in the Northeast, Pacific Northwest, and coastal California.

But the long math matters. Wood needs annual staining or sealing — that’s time, product cost, and labor every year. Composite requires nothing. Over 25 years, the maintenance savings on composite can narrow or even erase the upfront price gap.

Durability, Heat, and Daily Use Trade-Offs

There’s one real downside to composite in full-sun locations: it gets hot. Darker colors absorb more heat and can be uncomfortable for barefoot use in direct afternoon sun. Lighter composite colors or heat-mitigating product lines stay cooler. Wood generally stays cooler to the touch under the same conditions, which is why it’s still popular for pool decks and barefoot spaces.

Repairability and Aesthetic Differences

Part of the upfront cost of composite is betting that you won’t need repairs. A gouge, scratch, or stain on a composite board is there permanently. Wood lets you sand, stain, or replace individual boards as needed — repairs are straightforward and cheap, though they do add to the lifetime maintenance work.

Aesthetically, wood offers a natural grain that ages to a silver-gray patina unless you seal it annually to preserve the original color. Composite mimics wood grain, and premium capped lines look very close, but it’s still a manufactured surface. Which one looks better is personal, but if a natural, changing appearance matters, wood wins.

Sample Testing Before You Buy

If you’re considering composite for a full-sun deck, order samples from the manufacturer and leave them in your actual yard during peak sun hours. Test both the color you’re leaning toward and a lighter alternative. Surface temperature varies significantly by color and product line, and the brochure won’t tell you whether you’ll be comfortable walking on it barefoot in July.
