|---|---|---|---|
| Pressure-Treated | $50–$80/sf | $12,000–$18,000 | 10–15 yrs |

What Drives Cost Up
- Height — elevated decks require larger footings and more structural framing, adding $2,000–$6,000
- Stairs — each stair set adds $1,000–$2,500 depending on rise and material
- Railing type — aluminum balusters vs. cable or glass railings can swing $2,000–$5,000
- Site access — narrow side yards or steep slopes increase labor time significantly
Composite ROI: In Westchester's market, composite decks recover roughly 65–70% of their cost in home sale value. Pressure-treated decks recover a similar percentage at lower total cost. The long-term math on composite often wins for homeowners staying 7+ years.

Red flag: Be cautious of any deck quote that seems dramatically below others.
