Drive any street in Willow Glen or Cambrian after a wet winter and you can see it — green film creeping up north-facing stucco, black streaks under the eaves, mildew shadowing the fence line. San Jose's rhythm of wet winters, morning marine layer, and long dry summers feeds biological growth on the shaded side of a house while the sunny side collects dust and irrigation overspray. Mold and algae are not just a curb-appeal problem: they hold moisture against stucco and siding, and over time that breaks down paint and finish coats years ahead of schedule.
House washing done right is a chemistry job, not a pressure job. We apply a biodegradable cleaning solution at low pressure — gentle enough for stucco, fiber cement, vinyl, and painted wood — let it dwell, and rinse. The solution kills mold, algae, and mildew at the root instead of blasting the visible stain off and leaving the organism behind to regrow. That is why a soft washed house stays clean longer, and why we never point a high-pressure tip at siding.
Before any solution touches the wall, plants and garden beds near the house are pre-wet and kept wet through the wash, then rinsed with fresh water at the end. Exterior windows are rinsed as part of the job so you are not left with spotting. And we photograph every project before and after — you see exactly what changed, not just a cleaner-looking blur from the curb.
We wash houses across every corner of San Jose — the older wood-sided homes of Willow Glen, ranch stucco in Cambrian and Almaden, newer builds out in Evergreen, and the full mix up in Berryessa. Different materials and different decades, same standard: the right pressure and the right solution for each surface.

We walk the property first — noting siding material, stucco condition, and problem spots like peeling paint or hairline cracks — and photograph the house before a drop of water is applied.
Garden beds, shrubs, and lawn along the wash zone get soaked with fresh water before we start and stay wet throughout. Delicate plantings are rinsed continuously or covered.
Biodegradable soft wash solution goes on at roughly garden-hose pressure — safe for stucco, siding, and painted wood. No blasting, no water forced behind joints or into cracks.
The solution sits and works, killing mold, algae, and mildew at the root instead of stripping the surface stain. This is the step that keeps regrowth away for seasons, not weeks.
The whole exterior is rinsed from the eaves down, including every exterior window, so nothing dries streaked or spotted. Runoff is flushed off walkways and away from garden beds.
We re-shoot the same angles as the before photos and walk the results with you if you are home. Anything that needs a second pass gets one before we pack up.

These photos are from our Oakland Hills house wash — the same soft wash rig, solution, and process we bring to San Jose homes. The hero photo at the top of this page is our house washing job in Los Altos Hills. Every project gets documented like this, before and after.

Soft washing cleans at low pressure — close to garden-hose strength — using a biodegradable solution that kills mold, algae, and mildew at the root. Pressure washing relies on mechanical force, which is right for concrete but wrong for house exteriors. In San Jose we soft wash stucco, siding, and painted wood, and save high pressure for driveways and hardscape.
Yes. Most San Jose houses are stucco, and soft washing is the only method we recommend for it. High pressure erodes the finish coat and drives water into hairline cracks. Our low-pressure process lets the cleaning solution do the work, then rinses clean without scarring the texture.
No — protecting plants is built into the process. We pre-wet garden beds and shrubs near the house before any solution goes up, keep them wet during the wash, and give everything a final freshwater rinse afterward. The solution is biodegradable and dilutes quickly.
Not quickly. Because soft washing kills the organism rather than blasting the visible stain off the surface, regrowth takes much longer than after a pressure-only cleaning. Most San Jose homes stay clean for one to two years; heavily shaded north-facing walls may show growth sooner.
We rinse every exterior window as part of the wash so nothing is left spotted with solution or dirt. Detailed hand window cleaning is a separate service — ask when you call and we can quote both together.
All of them. We wash homes in Willow Glen, Cambrian, Almaden, Evergreen, and Berryessa every season, and we cover the rest of San Jose plus the South Bay, San Mateo County and lower Alameda County.
No. As long as we can reach exterior spigots and any gates are unlocked, we complete the job while you are out. We photograph the house before and after and send you the documentation when we finish.
