Deck staining costs vary based on size, condition, and preparation requirements. A typical residential deck ranges from $2-6 per square foot, including materials and labor. Factors affecting cost include current deck condition, amount of prep work needed, type of stain or paint selected, and accessibility challenges. Decks requiring extensive sanding, repair work, or multiple coats will cost more than well-maintained surfaces needing basic refreshing. We provide detailed, upfront estimates that break down preparation, materials, and labor costs. Our goal is competitive pricing without cutting corners on preparation or material quality, because proper work the first time costs less than fixing problems later.
