  "summary": "Stain, prep/cleaning, and labor cost per square foot of deck surface.",
  "description": "Deck staining cost depends on square footage, the condition of the existing wood (which drives prep labor like power washing, sanding, and old-stain stripping), and the stain type chosen — solid, semi-transparent, or clear/toner finishes all have different material costs and coverage rates. 2026 US national averages run roughly $1-$2 per sq ft for stain material and $1.50-$3.50 per sq ft for professional application labor, with heavily weathered decks needing stripping or sanding adding $0.75-$1.50 per sq ft in prep labor. A typical 300 sq ft deck therefore runs $750-$1,800 professionally stained depending on condition and stain quality. This calculator totals stain material, prep labor, and application labor by square footage so you can benchmark a painter's quote; railings and stairs typically add 15-25% more surface area than the deck floor alone, so measure carefully or use the railing multiplier included here.",
  "formula": "Total = Deck Sq Ft × (Stain Rate + Prep Rate + Application Rate) × (1 + Railing/Stairs Multiplier).",

    {
      "q": "Solid, semi-transparent, or clear stain — which costs more?",
      "a": "Solid stains cost slightly more per gallon and hide wood grain but last longest (3-5 years); semi-transparent shows grain and lasts 2-3 years; clear/toner finishes are cheapest per gallon but need reapplication almost yearly, often making them costlier over time."
    },
    {
      "q": "How much does old stain removal add to the cost?",
      "a": "Stripping old solid stain to bare wood before restaining can add $1-$2 per sq ft in labor and is one of the most time-consuming parts of a deck refresh — it's often why switching from solid back to semi-transparent stain costs more than staying with the same finish type."
    },
    {
      "q": "How often should a deck be restained?",
      "a": "Semi-transparent stains typically need reapplication every 2-3 years, solid stains every 3-5 years, and high-traffic or sun-exposed decks on the shorter end of those ranges regardless of stain type."
    },
    {
      "q": "Does weather affect staining cost or timing?",
      "a": "Yes — stain needs 48-72 hours of dry weather above roughly 50°F to cure properly, so scheduling around a clear weather window is essential and rescheduling due to rain is a common reason contractors build buffer days into quotes."
