What this shows

Material is the single biggest cost lever on a deck quote. Two decks of identical size and railing can land 2–3x apart on price depending solely on the deck-board choice. The comparison above covers the three options we install most often in the Upstate: pressure-treated southern yellow pine, capped composite (Trex- and TimberTech-class), and tropical hardwood (most commonly ipe or cumaru).

Pressure-treated is the value choice and still represents about 40% of our 2026 deck quotes, but its long-term math is the worst of the three. Carolina UV and humidity break down PT boards aggressively, and homeowners who don't re-stain on a strict 18–24 month cadence see board cupping and surface checking inside six years. Capped composite has overtaken PT as the most-installed material in our pipeline, primarily because the 25-year warranty matches what most homeowners actually want from a deck: build it, enjoy it, never sand it again. Hardwood is the smallest slice (under 10% of quotes) but the most beautiful, and a properly detailed ipe deck will outlast the house it's attached to.

Our usual recommendation: if the deck will be visible from the primary living space and you plan to stay 5+ years, composite is the right answer for most Upstate homeowners. If the deck is utilitarian and budget is tight, pressure-treated is honest. Hardwood is for clients who want a furniture-grade outdoor space and are committed to occasional oiling.

Key takeaways

  • Capped composite has overtaken pressure-treated as the most-installed deck material in our 2026 pipeline.
  • Pressure-treated pine is cheapest up front but has the worst 10-year ownership math in the Upstate climate.
  • Tropical hardwood is the premium choice — highest cost, longest life, lowest maintenance frequency.
