Three things separate us from competitors who advertise "soft washing" but really just attach a soap tip to a pressure washer. First, we operate a dedicated soft wash system with a proper pump that delivers solution at the correct concentration and dwell time. Second, we calibrate the chemistry to the specific surface — vinyl, EIFS, Hardie board, brick, cedar, and stone all require different mixes. Third, we're built for estate-scale homes — 5,000+ sq ft properties, three-story facades, and gated communities in Potomac, Bethesda, McLean, and Great Falls are routine for us, not the exception.

Soft wash pricing depends on square footage, home height, siding material, and access. For a typical 3,500 to 5,000 sq ft home in Potomac, Bethesda, McLean, or Great Falls, whole-home soft washing generally ranges from $600 to $1,400+. Larger estates with three-story sections, extensive trim work, or detached structures price higher. Every quote is provided in writing after an on-site walkthrough — no surprise fees, no upsells.

A properly performed soft wash lasts 3 to 5 years on most siding surfaces — roughly four times longer than pressure washing. The reason is biological: our solution kills mold spores, mildew, and algae at the cellular level rather than just rinsing them off the surface. Pressure washing only displaces visible growth, which is why it typically returns within 6 to 12 months in the humid DMV climate. Shaded north-facing walls and wooded lots in Potomac, Great Falls, and McLean may need cleaning slightly sooner.

EIFS and synthetic stucco are exactly where soft washing matters most. High pressure on EIFS is one of the fastest ways to cause moisture intrusion behind the finish and lead to expensive structural repairs. Our soft wash approach uses under 100 PSI and lets the chemistry do the cleaning, which is the only method we'll use on EIFS, synthetic stucco, or three-coat hard-coat stucco. It's the EIFS Industry Members Association (EIMA) recommended approach.

Yes. The black streaks on asphalt shingle roofs are caused by Gloeocapsa magma — a blue-green algae that feeds on the limestone filler in asphalt shingles. Soft washing is the only method endorsed by ARMA (Asphalt Roofing Manufacturers Association) for removing it. Pressure washing a roof will void your shingle warranty and dislodge granules, dramatically shortening roof life. Our soft wash roof treatment kills the algae at the root and prevents regrowth for years.

No — when done correctly. Every job follows the same landscape protection protocol: pre-saturate all plants, shrubs, and lawn areas with fresh water before mixing chemical; tarp sensitive specimen plants or hand-pruned beds when needed; and post-rinse the entire perimeter after the wash to dilute any overspray. The hand-pruned boxwoods and hydrangea beds in Potomac, Avenel, and River Bend don't get chemical-burned on our watch.

Yes — regularly. We service Avenel, River Bend, Falconhurst, Bradley Farms, Lake Potomac, Salona Village, and other gated and HOA neighborhoods across both counties. We provide certificates of insurance on request, follow vendor entry protocols, schedule around community quiet hours, and run a uniformed crew with marked vehicles. Just let us know the community requirements when you book and we'll have paperwork ready before arrival.

Yes. James Hardie's own care guidelines specifically recommend low-pressure cleaning — our system meets and exceeds that spec. Cedar shake and stained wood are cleaned without raising grain, splintering, or lifting stain. Historic painted trim on older Chevy Chase Village, Kensington, and McLean homes requires a chemical-only approach with zero mechanical pressure, which is exactly what soft washing delivers. We adjust solution strength based on substrate to protect every finish.

This is the most important distinction in the industry, and most companies blur it. True soft washing uses a dedicated 12-volt or air-driven pump that applies cleaning solution at full strength under 100 PSI, with proper dwell time on the surface before rinsing. "Pressure washing with chemicals" uses a downstream injector on a 4 GPM pressure washer, which dilutes the solution roughly 10-to-1 and delivers it at higher pressure for less time. The first method cleans through chemistry; the second method is mostly rinsing. We use the first.

For a typical 3,500 to 5,000 sq ft luxury home in Potomac, Bethesda, McLean, or Great Falls, a full soft wash takes 3 to 6 hours start to finish — including setup, landscape pre-wet, application with proper dwell time, full rinse, and post-job landscape flush. Larger estates with extensive trim, multiple structures, or three-story sections can run a full day. We'll give you a realistic time window when we provide the on-site estimate.

No — soft washing is the warranty-compliant method for every major siding manufacturer, including James Hardie, CertainTeed, Mastic, Royal, and Alside. High-pressure washing is what can void a vinyl or fiber cement siding warranty, because it can force water behind the siding and damage the protective finish. Our soft wash method is the cleaning approach manufacturers actually recommend.
