Soft washing is how exterior walls should be cleaned in Lubbock: 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 Lubbock. 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 Lubbock this is not a preference, it is the correct method.
On nearly every Lubbock property, the north and shaded elevations carry visible organic growth while the sunny sides look fine. Shade holds moisture, and moisture grows algae and mildew on any surface that will hold it. Pressure removes the visible layer and leaves the biology, so it returns fast. A soft wash with the correct solution kills the growth rather than just knocking it off, which is why the result lasts a season or two instead of a few months.
Lubbock is on City of Lubbock water: Bailey County and Roberts County well fields in the Ogallala Aquifer, blended with Lake Alan Henry and Lake Meredith. West Texas water is hard, and this climate is built to evaporate it: low humidity, strong sun and steady wind. Sprinkler heads near the house, a hose rinse left to air-dry, and lawn irrigation that clips the lower panes all leave white mineral spots behind, and in this sun they bond to the glass within days instead of sitting loose on top. Caught in the first season they wash off with the right chemistry. Left for a few summers they etch, and etching is in the glass, not on it.
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.

Fast-growing Frenship-area subdivisions southwest of town, with new-build construction haze and open-field dust.
Lake and canyon homes southeast of town with big view windows that are hard to reach.
Historic homes on tree-lined streets across from Texas Tech, between 19th and 34th. Older windows and hand-set glass, worked by hand with care.
North and South Overton near campus, with a mix of older homes and new infill. Construction dust from the infill is the standing issue.

Southwest Lubbock around Lakeridge Country Club, with larger homes and a lot of rear-facing glass.

Lubbock is in the South Plains. Sonlight opens here Saturday, November 7, 2026. Glass in this part of Texas deals with spring wind and dust storms off open ground, hard water that dries fast in strong sun, and hail in the spring storm season.
Brick, stucco and siding get low-pressure soft washing, mildest chemistry first. High pressure drives water and grit into mortar joints and stucco, and the damage shows up later as staining and moisture problems.
Pressure washing uses force; soft washing uses chemistry at low pressure. Hard surfaces like Lubbock 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.
