Walking Surfaces That Aren't Slippery

Deck Washing in Fairmont for wood and composite decks with visible mildew and discoloration

Decks accumulate layers of mildew, dirt, and organic debris that create slippery surfaces and hide the wood grain or composite texture underneath. Wet Boys Power Washing removes this buildup using pressure levels calibrated to your deck material—wood receives different treatment than composite to avoid splintering or surface damage while still achieving effective cleaning. In Fairmont's humid climate, decks in shaded areas develop thick algae coats that turn black or green, particularly on boards that never get direct sun to dry them out between rain events.


The cleaning process strips away years of accumulated grime and restores the natural appearance of the decking, whether that's the grain pattern of pressure-treated lumber or the uniform texture of composite planks. Proper washing also prepares surfaces for staining or sealing if you're planning that additional step, since sealers won't bond properly to dirty or mildewed wood.


Request a detailed estimate based on your deck's size and current condition to understand what full restoration involves.

What Changes After Deck Washing

Deck washing begins with clearing furniture and planters, then treating the entire surface with appropriate pressure—typically 1200 to 1500 PSI for wood and lower for composite materials that can show permanent streaking if washed too aggressively. The process works across the grain on wood decks to lift embedded dirt without gouging softer spring growth between harder grain lines.


After completion, your deck shows its original color instead of gray weathering or black mildew staining. Boards feel textured rather than slimy, and the surface provides better traction when wet since the algae layer that made it dangerously slippery is completely gone. If you're planning to stain or seal, the cleaned wood absorbs products evenly instead of showing blotchy areas where grime blocked penetration.


The service works best as seasonal maintenance before summer use or after fall leaf drop, though it's also effective as preparation before selling a home since clean decks photograph dramatically better than mildewed ones. Bundling with fence washing makes sense when both structures share similar materials and condition, reducing overall project time.

Answers to Frequent Service Questions

Deck washing involves specific considerations about materials, timing, and follow-up maintenance that homeowners ask about regularly.

  • How does the washing process differ for wood versus composite decks?

    Wood decks receive pressure washing at levels that remove dirt and mildew without raising grain or splintering soft spots, while composite decks require lower pressure to prevent surface damage and streaking that can permanently mark certain composite formulations.

  • What preparation do homeowners need to complete before deck washing?

    You'll need to remove furniture, planters, grills, and other items from the deck surface so every board receives thorough cleaning, and it helps to trim back any vegetation touching the deck perimeter to prevent plant damage from overspray.

  • Why does deck washing improve safety beyond just appearance?

    Removing algae and mildew eliminates the slippery biofilm that makes wet decks dangerously slick, particularly on stairs and high-traffic areas where worn surfaces already provide less traction than newer wood or composite materials.

  • When is the ideal time to wash decks in Fairmont?

    Spring cleaning before outdoor entertaining season and fall washing after leaves drop both work well, with moderate temperatures allowing surfaces to dry completely and avoiding the freeze risk that makes winter washing impractical in this climate.

  • How soon after washing can homeowners apply stain or sealer?

    Wood decks need at least 48 hours of dry weather to release absorbed moisture before staining, since applying products to damp wood traps moisture that causes premature failure and peeling of the finish layer.

Wet Boys Power Washing tailors deck cleaning methods to your specific material and condition, ensuring effective results without the surface damage that comes from incorrect pressure levels. Arrange an evaluation to review your deck's current state and discuss bundling options with fence or full exterior cleaning.
