Pressure Washing in Dominion Valley
House soft washing, driveways, walkways & roofs — done by a neighbor who lives in the community.
Cornerstone Property Care is based right here in Dominion Valley Country Club. The owner lives in the community, drives the same streets you do, and answers the phone himself — so when your home in Regency, Amberleigh, or one of the village neighborhoods off Dominion Valley Drive needs its siding, driveway, or walkways cleaned up, you are hiring a neighbor, not a crew dispatched in from an hour away.
The homes here — mostly newer Toll Brothers and Brookfield builds with a mix of vinyl siding, Hardie board, and brick — look fantastic when they are kept up. But Northern Virginia weather works against them year-round, and Dominion Valley’s mature tree canopy and shaded lots make it worse. We bring the curb appeal back without damaging your finishes or your landscaping.
Why Dominion Valley homes get dirty fast
It is not your imagination — exterior surfaces in this part of Prince William County need attention more often than the national average, and here is why:
- Humid summers breed algae and mildew. That green-black film on north-facing siding, shaded brick, and the bottom courses near the foundation is living growth, not just dirt. It comes back unless it is killed at the root, not just blasted off.
- Mature trees mean organic staining. Dominion Valley’s established canopy drops pollen, sap, leaf tannins, and seeds onto roofs, decks, and concrete — leaving the dark streaks and gray haze you see on driveways and walkways.
- Red Virginia clay stains hardscape. Our soil leaves a rust-orange film on concrete, pavers, and the lower siding that a garden hose will never touch.
- Freeze-thaw drives grime deeper. Winter cycles push dirt and biological growth into the pores of concrete and the texture of Hardie board, so it sets in harder every year it is left.
What we clean in Dominion Valley
House & Siding Soft Washing
Vinyl, Hardie, and brick get a low-pressure soft wash with a cleaning solution that kills algae and mildew at the root — so it stays gone for months, not days. No water forced behind your siding, no etched surfaces.
Driveways, Walkways & Patios
Concrete, pavers, and aggregate get surface-cleaned to pull out the gray biofilm, red-clay staining, and tire marks. We finish edges and seams evenly — no zebra striping from a careless wand.
Roof Soft Washing
Those black streaks on your shingles are Gloeocapsa magma — a roof algae that eats at granules over time. We treat it with a no-pressure soft wash that is safe for asphalt shingles and your manufacturer warranty.
Decks, Fences & Pre-Stain Prep
We clean wood and composite decks and fences gently, and prep deck boards before a re-stain. Pair it with our deck repair & staining for a full refresh in one visit.
SOFT WASH, NOT BLAST
The right pressure for the right surface
“Pressure washing” is the search term, but on a home you almost never want full pressure. High PSI cracks vinyl, forces water behind siding, etches Hardie board, and strips mortar from brick. The fix for algae and mildew is a low-pressure soft wash — a cleaning solution does the work, then we rinse. That is what makes the growth stay gone instead of greening back up in a few weeks.
We save real pressure for the surfaces that can take it — concrete driveways, walkways, and patios — using a flat-surface cleaner that delivers an even result without the wand stripes a lot of homeowners end up with. Matching the method to the material is the whole job, and it is why your finishes and your landscaping come through clean and undamaged.
Keeping your home HOA-friendly
The Dominion Valley Owners Association keeps the community looking sharp, and that includes home exteriors. Green-streaked siding, a stained driveway, or a mildewed walkway is exactly the kind of thing that draws a friendly reminder letter. A scheduled wash keeps your home looking the way the neighborhood expects — and because we live here, we understand the standard you are trying to hold to.
Most homes here do well with a house soft wash once a year and concrete cleaned as needed. We are glad to take a look and tell you honestly what does and does not need doing — no upselling a roof wash you do not need yet.
Dominion Valley pressure washing FAQs
How often should I wash my house in Dominion Valley?
For most homes here, once a year keeps siding ahead of the algae and mildew our humid summers cause. North-facing and heavily shaded walls under the tree canopy can green up faster and may benefit from a touch-up. Concrete is more about appearance — we clean it when the gray and clay staining bothers you.
Will pressure washing damage my vinyl or Hardie siding?
Not the way we do it. We soft wash siding at low pressure and let the cleaning solution lift the growth, so there is no risk of cracking vinyl, etching Hardie board, or driving water behind the panels. Full pressure is reserved for concrete and other hard surfaces that can handle it.

Yes. Dominion Valley is home base, and we also serve Piedmont, Heritage Hunt, Evergreen, the Town of Haymarket, and Gainesville. Staying tight to this area is what lets us show up on time and keep quality high.
