- Herndon's housing stock compounds the problemEstablished communities like Herndon Centennial and Colonial Village carry decks and fences built in the 1980s and 1990s — wood old enough that decades of freeze-thaw cycles and Virginia humidity have already opened the grain, making it more absorbent and more vulnerable.

Herndon, Answered
Deck & Fence Cleaning in Herndon — Common Questions
Will soft-wash cleaning damage my composite deck?
No. Soft-wash uses low pressure and a cleaning solution designed to lift algae, mold, and graying without the abrasive force that can scuff or streak composite boards like Trex or TimberTech. We match pressure and dwell time to the manufacturer's care guidance for your specific material.
Why does my deck in a shaded Herndon yard gray and mildew faster than a friend's deck in an open lot?
Herndon's mature tree canopy keeps shaded decks and fences damp longer after rain or morning dew, which accelerates mold and algae growth and slows the natural drying that helps wood resist graying. Lots near Fox Mill Estates, Franklin Farm, and similar tree-heavy communities see this pattern most.
Can you clean a wood fence without stripping the existing stain?
Yes. Our soft-wash process is calibrated to remove dirt, mildew, and algae buildup while leaving sound stain and sealant intact. If a fence has failing or peeling stain, we'll flag it during the walkthrough so you know what to expect before we start. Our crews work Herndon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
How often should decks and fences be cleaned in a tree-covered Herndon yard?
Most shaded properties in Herndon benefit from a cleaning once a year, typically spring or early summer, to stay ahead of mildew before it embeds in the grain. Yards with heavier canopy or standing shade may need a check sooner. Our crews work Herndon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Do you clean both sides of a shared fence line?
We clean the side of the fence that's on your property and accessible from your yard. For shared fence lines common in tighter Herndon lots near Worldgate and Dulles Station, we're happy to coordinate with a neighbor if both sides need attention. Our crews work Herndon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Is soft-wash safe for the landscaping and root zones near my deck?
Yes. Given Herndon's tree-heavy lots and tight setbacks, we select cleaning solutions and control runoff specifically to avoid harming nearby plantings, mulch beds, and root zones during the wash. Our crews work Herndon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
How much does deck cleaning cost in Northern Virginia?
Most decks run $200–$500 depending on size and condition; fences typically price at $3–$6 per linear foot. Cleaning both together, or bundling with house washing, lowers the combined price — quotes are always written and line-item. A deck-and-fence combined visit is the most common booking — the equipment and detergents overlap, and the property reads as one refreshed space afterward. Serving Herndon and all of Fairfax County.
