Soft washing is how exterior walls should be cleaned in Cedar Park: low pressure, the right solution, adequate dwell time, and a gentle rinse. It handles the organic growth and film that pressure cannot remove without damage, and on siding, painted surfaces, and stucco it is the only appropriate method.
Quick answer
Soft wash kills mildew, algae, and bacteria on exterior surfaces using low pressure (~500 PSI) and a biocidal cleaning solution.
The checklist is the same everywhere. What is on your glass is not. These are the conditions that actually shape this job in Cedar Park. Each one is true here and false in plenty of other towns we serve.
Siding and painted surfaces have seams, laps, and fasteners. High pressure drives water past the surface into the assembly behind it, and it does not dry out from there. The result appears weeks or months later as blistering, staining, or a moisture problem that gets blamed on something else. Soft washing puts the work on the chemistry instead of the force, which cleans more thoroughly and leaves the wall intact. In Cedar Park this is not a preference, it is the correct method.
Low-pressure (~500 PSI) wash of every exterior surface: vinyl, fiber-cement (Hardie), stucco, painted wood, brick, masonry. Hardware-friendly: trim, gutters, soffit, and fascia all included.
Biocide application: sodium hypochlorite-based solution (the standard for soft-wash) that kills mildew, algae, lichen, and the black/green biological staining you see on shaded north-facing walls.
Plant and lawn protection, surfactant rinse during application, then full rinse-down at the end so nothing carries to your landscape.
Window pre-coat, we coat windows with plain water before the biocide so any drift doesn't streak the glass. We can also include the windows in the same trip, soft wash + window cleaning is a popular combo.
Optional add-ons: deck soft-wash, fence soft-wash, full-property bundle with driveway pressure wash.
Enter your address. Our autoquoter sizes the home; we'll confirm siding type and any add-ons when scheduling.
Plant covers, lawn pre-rinse, window pre-coat (plain water). Pets indoors. We tape any wall outlets or vents that need protection.
Top-down soft-wash with the biocidal solution. Dwell time 5-15 minutes, long enough to kill the biological staining, not long enough to damage paint.
Plain-water rinse from top to bottom to remove all solution and dead biological material. We watch for any streaking and re-apply if needed.
Walk-around to confirm clean coverage, plants and lawn rinsed, no overspray on neighbors. Before/after photos emailed.

Pressure washing uses force; soft washing uses chemistry at low pressure. Hard surfaces like Cedar Park driveways and walks take pressure fine. Walls, siding, painted surfaces, stucco, should never take it, because pressure drives water into the assembly where it causes damage that shows up later. Soft washing cleans those surfaces more thoroughly and does not put moisture where it does not belong.
A season to two years depending on exposure. North and shaded elevations regrow first because they hold moisture. The reason a soft wash lasts longer than a pressure wash is that the solution kills the organic growth rather than just removing what is visible, pressure leaves the biology behind and it comes back within months.
Soft wash uses low pressure (~500 PSI) and a biocidal cleaning solution. Pressure wash uses high pressure (~3,000 PSI) and mechanical force. Soft-wash is for siding, stucco, painted wood. Anything that high pressure could damage. Pressure wash is for concrete, brick, and other durable hard surfaces.
No, when done properly. We pre-rinse plants and lawn before applying the biocide, use a surfactant during application, and do a full final rinse so nothing accumulates. Plants are the same green color when we leave as when we arrived.
Yes. Soft wash is the right tool for stucco, high-pressure washing damages stucco by pushing water behind the surface and eroding the texture. Soft-wash cleans without any mechanical force on the surface itself.
Yes. Wood decks, composite decks, and painted wood decks all benefit from soft wash. The biocide kills the black mildew that builds up between deck boards. Pre-stain or pre-paint prep is a common request.
