What goes into the price of a 12x10 deck

  • Material — the single biggest swing, from budget pressure-treated to premium composite or hardwood.
  • Height — a raised or second-story 12x10 deck costs more than a ground-level one.
  • Railing & stairs — included above; removing them lowers the price.
  • Labor vs DIY — labor is often close to half the total.
