Deck & Fence Cleaning in Garden City Beach, SC

Wood and composite decking and fencing gray and roughen from sun and moisture exposure over time. On natural wood, UV exposure breaks down the top layer of fibers while moisture encourages mildew, leaving a rough, discolored surface. Composite decking doesn't rot the same way, but it does collect surface grime and mildew film that dulls its color.

Cleaning restores the surface before staining or sealing — this step matters because a new coat of stain or sealant applied over dirt, mildew, or old failing sealant won't bond properly and will peel or fail early. A proper wash strips that layer away so the new finish adheres to bare, clean wood or composite.

Pressure is adjusted to the material: wood needs a gentler approach than concrete to avoid raising the grain, splintering the surface, or blasting soft spots in aging boards. Composite decking manufacturers typically specify a maximum pressure and a fan-tip nozzle to avoid surface damage.

Fence cleaning follows the same logic — wood fencing gets a lower-pressure, wider-fan approach, with extra attention to the base of posts where soil splash-back and moisture cause the most buildup. Vinyl and metal fencing can generally handle standard pressure.

A cleaned deck or fence left unsealed will gray again within months, so cleaning is usually timed a few days before staining or sealing to let the wood dry fully first. Call for a quote — deck and fence square footage, material, and current condition all affect pricing.
