How Much Does House Washing Cost in Ashburn, VA? (2026 Pricing Guide)

What Affects the Cost of House Washing in Ashburn

Every Ashburn home is a little different, and pricing reflects the real work involved. The biggest factors:

• Home size (square footage) — larger footprints take more product and time.
• Number of stories — two- and three-story homes need extended reach equipment.
• Siding type — vinyl, HardiePlank, stucco, brick, and painted wood each rinse differently.
• Algae and mildew severity — heavy north-side green or black streaking needs longer dwell time and more algaecide.
• Add-ons — gutter face brightening, soffits, downspouts, and attached porches or sunrooms.

Soft Wash vs. Pressure Wash

Houses in Ashburn should always be soft washed, not pressure washed. The two are not interchangeable:

• Soft wash (~200 PSI or less) — a gentle, low-pressure application of a cleaning solution that kills algae, mildew, and mold at the root, then a rinse. Safe for siding, paint, and window seals.
• Pressure wash (2,000-3,500 PSI) — high-pressure water for hard surfaces like concrete driveways, sidewalks, and patios. Never appropriate for siding.

Using pressure on siding can force water behind panels, strip paint, and void manufacturer warranties. Every Pristine America Washing house cleaning is a true soft wash.

What's Included in a Pristine America House Wash

• Professional-grade algaecide treatment that kills organic growth at the root so it doesn't grow back in weeks
• Low-pressure rinse of siding, soffits, eaves, shutters, and downspout exteriors
• Landscape protection — pre-wetting plants and grass, dilution rinses after
• Pet and electrical safety — outlets covered, exterior lights and fixtures worked around, pets kept safe
• Cleanup and a walkthrough before we leave
