Trusted on Homes Like Yours
“We hired Lawn Theory for pressure washing and landscaping. It is like we have a brand new home. Five stars!”
“They explained why they'd soft-wash our deck instead of blasting it with a wand, and I appreciated that. Came out clean without a single splintered board.”
“Written quote same day, on time for the appointment, and our HOA letter about the driveway staining is officially resolved. Would use again for our patio next.”
Mount Vernon, Answered
Deck & Fence Cleaning in Mount Vernon — Common Questions
Is soft-washing safe for both wood and composite decking?
Yes. Soft-washing uses low pressure combined with a cleaning solution matched to the material, so it lifts mildew, algae, and graying without the fiber damage a high-pressure wash can cause on softwood or the surface etching it can cause on composite boards like Trex or TimberTech.
Why does my deck gray or turn green so fast under our trees?
Mount Vernon's mature tree canopy keeps decks and fences shaded and damp longer than open lots, which accelerates both UV graying on exposed boards and mildew growth in shaded, moisture-trapping areas \— especially common on north-facing fence lines near wooded lots. Our crews work Mount Vernon 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.
Will pressure washing strip my deck's stain or seal?
Standard high-pressure washing often does, which is why Lawn Theory uses soft-wash methods instead \— low pressure with the right dwell time cleans the surface without stripping an intact stain or sealant coat. Our crews work Mount Vernon 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 this area?
Given the tree cover and river humidity common across Mount Vernon, most wood decks and fences benefit from a cleaning once or twice a year, timed before staining season in spring or after heavy leaf drop in fall. Our crews work Mount Vernon 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 fences too, or just decks?
Both. Privacy fences, split-rail, and picket fencing all get the same material-specific soft-wash treatment as decking, since fence lines bordering wooded lots are often the first place mildew and algae show up. Our crews work Mount Vernon 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.
What areas of Mount Vernon do you service?
Lawn Theory covers the full Mount Vernon area of Fairfax County, including Belle Haven, Hollin Hills, Fort Hunt, Waynewood, Wellington, Riverside Estates, Stratford Landing, and the surrounding neighborhoods along the George Washington Memorial Parkway. Our crews work Mount Vernon 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.
