For construction professionals, knowing the precise costs of power washing and staining a deck is crucial. Typically, costs range from $1.40 to $2.80 per square foot. This guide provides a detailed breakdown of cost factors, including deck size, lumber type, and stain selection, ensuring accurate budgeting and efficient project management.
Accurate measurements are essential. A 12 × 12 deck differs significantly from a 400 sq ft multilevel layout, affecting the amount of wash time and materials needed.
• Light dirt requires a 2,000-psi rinse.

Cedar and pressure-treated pine absorb stain differently than hardwoods like ipe, impacting material costs.
Labor costs can vary by 15-25% depending on the region, affecting overall project expenses.
• Clear sealers are less expensive but require frequent re-coating.
• Semi-transparent stains offer a balance of cost and durability.
