What Affects the Price?

  • Demolition: Removing and disposing of an old deck adds labor and dumpster fees.
  • Height: Elevated decks require larger posts, more bracing, and longer build times.
  • Railings: Cable rails and glass cost significantly more than standard wood spindles.
  • Stairs: Custom landings and wrap-around steps increase framing complexity.
