Exterior whole-home soft-wash in Los Altos Hills.

Whole-home exterior cleaning is rarely a pressure job. Stucco, painted siding, fiber-cement, and roof tile each respond best to low-pressure chemistry application — soft-wash — that lifts biological staining without driving water behind the finish or stripping paint. Done right, an annual soft-wash refresh extends the visual life of the exterior between paint cycles by years.

In Los Altos Hills, the conditions of the Mid-Peninsula hillside market sharpen the need. Los Altos Hills facades under hillside canopy and fog exposure develop biological staining, and soft-wash chemistry cleans painted and stucco surfaces without driving water behind the finish.

1. Walk-around inspection of all exterior surfaces, paint integrity, and biological staining concentration.
2. Soft-wash chemistry applied to facades, roof tile, and trim with appropriate dwell time.
3. Controlled rinse at low pressure to lift residue without finish damage.
4. Final inspection with the homeowner of any surface that needs separate paint, repair, or specialty attention.

• Annual exterior refresh, often timed with pre-event or pre-listing windows.
• After a hurricane, wildfire, or storm event that has driven debris or smoke onto exterior surfaces.
• When the exterior visibly darkens or shows uneven biological staining.
• Mid-paint-cycle, where soft-wash can extend the visual life of the existing paint by months or years.
