What Is Power Washing and Why Is It Important for Decks?
Power washing uses high-pressure water jets to remove dirt, grime, moss, and mildew from deck surfaces. This cleaning method prepares decks for staining, painting, or sealing, ensuring longer-lasting protection against the elements. Regular power washing prevents wood rot, slippery surfaces, and discoloration caused by mold or algae growth. Homeowners aiming to maintain their deck’s safety and attractiveness benefit significantly from periodic power washing.
Key Factors Affecting the Cost to Power Wash a Deck
The price of power washing a deck depends on many variables. The most notable include:
Deck Size
Most professionals charge based on the deck’s square footage, typically $25 to $75 per 100 square feet. Larger decks require more time, equipment use, and water, increasing the overall cost.
Deck Material
Wood decks, especially softwoods like pine or cedar, demand gentler pressure to avoid damage, which may increase labor intensity and price. Composite and vinyl decks often require specialized cleaning solutions, affecting the cost as well.
Location and Labor Rates
Labor costs vary across the U.S., with metropolitan areas generally costing more due to higher wages and operational expenses. Remote or rural locations might incur additional travel charges.
Additional Services
Mildew removal, stain or sealant application, and repairs can raise the overall cost. Some companies offer bundled packages that include these treatments post power wash.
