Deck building cost in the U.S.

New decks fall in the range below for typical residential sizes. Material is the dominant variable; rails, stairs, and footings are the rest.

Industry estimate from public-source pricing data. Local prices vary widely — see your metro area below.

Factors that move the price

  • Material per sq ft
    Pressure-treated pine: cheapest. Cedar: mid. Composite (Trex, TimberTech): higher but no annual sealing. PVC: highest, fully synthetic.
  • Footings + foundation
    Concrete piers below frost line are non-negotiable in cold climates. Helical piles are an upgrade. Slope + soil type changes labor materially.
  • Rails + stairs
    Cable rail, aluminum balusters, and glass panels are 3-5× the cost of wood balusters. Stairs are 1.5-2× a square foot of deck. Multiple landings multiply both.
  • Height + permit
    Anything over 30 inches off grade triggers a code-compliant rail and almost certainly a permit. Pergolas, built-in seating, and roofs are separate line items.

Common questions

Is composite decking really worth the cost?
Over 20 years, yes — no annual sanding, sealing, or board replacement. Up front, composite is ~1.5-2× the cost of pressure-treated pine.
