PVC (or cellular PVC) decking is 100% plastic — no wood fibers. Brands like AZEK, Wolf, and Deckorators Vault dominate this tier. Installed pricing runs $45–$75 per square foot in 2026 — the most expensive mainstream decking, but waterproof, hot-day-stable, and the longest-lasting category short of tropical hardwood.
Why PVC costs more than composite
PVC uses 100% virgin or recycled plastic — no wood filler. That means zero moisture absorption, zero mold risk, and virtually zero fade. The board material itself runs $6–$10/linear foot (vs $4–$9 for composite), but the bigger driver is fastener-specific hardware (hidden clips that grip PVC don't grip composite) and installer skill — fewer crews are certified for PVC.
AZEK vs Trex (the two category leaders)
AZEK is pure PVC, owned by the TimberTech parent company. Trex Transcend is composite with a PVC cap — so only the outer 1/16" is PVC. In practice: AZEK runs 5–10°F cooler in sun, holds color slightly better past year 15, and survives pool-side splash-out indefinitely. Trex wins on installed cost by $5–10/sqft.
Where PVC shines
Pool surrounds, coastal installs, shaded wet decks, and hot climates (AZ, TX, FL) where composite gets uncomfortably warm underfoot. PVC is also lighter than composite, so it's the right choice for second-story or roof-deck builds where weight matters.
Limits to watch for
PVC expands and contracts more with temperature than composite — installers have to leave slightly larger gaps on board-ends. Dropped heavy objects can crack the cellular foam core (rare, but visible when it happens). Color selection is narrower than premium composite.
PVC / Cellular deck cost by state — 300 sqft build
Standard 12×25 deck, 3–5 ft off ground, composite balusters, one stair run. Includes framing, footings, railing, stairs, permit, and 8% contingency.
Installed: $45–$75 per square foot in 2026. Board-only: $6–$10 per linear foot for a 12-foot board. Labor runs 45–55% of the installed total — similar to composite, slightly more than PT.
Is PVC decking worth the money over composite?+
Yes in three scenarios: pool and water-adjacent decks (PVC is waterproof, composite absorbs minor moisture through the exposed bottom), hot-sun decks where temperature matters, and installs you want to fully forget for 30 years. Everywhere else, premium composite (Trex Transcend) gets 90% of the benefit at 80% of the cost.
Does PVC decking get hot?+
Less than most composite. In direct summer sun, light-color PVC runs 5–10°F cooler than equivalent composite and 15–20°F cooler than dark PT stained black. Still warm to barefoot touch on 90°F+ days, but workable.
Does PVC decking fade?+
Less than any other material. AZEK and Wolf carry 50-year limited fade-and-stain warranties. Expect near-zero visible fade through year 15 and slight lightening after year 20 on south-facing installs.
Can PVC decking be used for stairs and railings?+
Yes — most PVC systems include matched stair-tread and railing components. Stair treads are premium priced ($15–$22 each); most installs combine PVC decking with powder-coated aluminum railing to keep railing cost in check.
