Professional pressure washing and soft washing for Portola Valley homes and estates. We remove years of grime, algae, and staining from driveways, roofs, decks, and siding — without damaging your property. Serving Portola Valley and the surrounding Peninsula since day one.
Portola Valley's wooded terrain, coastal humidity, and oak tree canopy create ideal conditions for algae, moss, and organic staining to accumulate on driveways, roofs, fences, and home exteriors. What looks like ordinary dirt is often deeply embedded biological growth — and a standard garden hose won't touch it.
Willow Wash LLC brings professional-grade pressure washing and low-pressure soft washing directly to Portola Valley properties. We use the right pressure, the right chemistry, and the right technique for every surface type — whether that's a slate roof, a stamped concrete driveway, a redwood deck, or a painted stucco exterior.
We're a hands-on, two-man operation — which means the people who show up are the people who care about the outcome. No subcontractors. No shortcuts. Just clean.
From driveways to rooftops, we clean every exterior surface on your Portola Valley property using the appropriate pressure and technique for long-lasting results.
Low-pressure soft washing safely removes algae, mold, mildew, and oxidation from stucco, wood siding, brick, and painted surfaces. Protects your paint and finish while delivering a deeper clean than pressure washing alone.
We strip oil stains, rust, tire marks, and embedded dirt from concrete and paver driveways using high-pressure surface cleaning equipment. Leaves a uniform, streak-free finish that dramatically improves curb appeal.
Black streaking on your roof is Gloeocapsa magma — a cyanobacteria that eats away at asphalt shingles. Our low-pressure soft wash treatment eliminates it at the root, restoring your roof's appearance and extending its lifespan.
Portola Valley's oak canopy leaves decks covered in tannin stains, mold, and slippery algae. We pressure wash wood, composite, and stone patios to a clean, safe surface — a must before any sealing or staining project.
Wood fences, retaining walls, and masonry accumulate green algae and grime fast in shaded, moist environments. We restore color and texture without damaging wood grain or mortar joints.
We handle commercial buildings, multi-unit properties, and HOA common areas in and around Portola Valley. Scheduled maintenance programs available — keep your property compliant and visually sharp year-round.
Four straightforward steps from your first call to a spotless property. No guesswork, no surprises — just a clean result on schedule.

Pressure washing uses high-pressure water to blast away dirt and staining — ideal for concrete, brick, and pavers. Soft washing uses low-pressure water combined with biodegradable cleaning solutions to safely clean more delicate surfaces like roofs, painted siding, and wood fences. Using high pressure on the wrong surface can strip paint, etch wood, or void roofing warranties. We use the correct method for every surface we clean.
Yes. We pre-wet all surrounding plant beds before applying any cleaning solutions, use biodegradable detergents, and rinse thoroughly once the job is complete. Portola Valley's native landscaping and ornamental plantings are taken into account — we're careful around your garden, not just your structure.
For most Portola Valley properties, once or twice a year is sufficient. Homes under heavy tree canopy — especially oaks and bay laurels — tend to accumulate organic debris, algae, and tannin staining faster and benefit from bi-annual cleaning. Driveways, roofs, and north-facing surfaces typically need more frequent attention than south-facing walls. We'll give you an honest recommendation after assessing your specific property.
Yes. We use a low-pressure soft wash process specifically designed for roof cleaning that eliminates algae, moss, and the black streaking caused by Gloeocapsa magma bacteria — without damaging shingles or voiding manufacturer warranties. High-pressure washing on a roof causes granule loss and accelerates deterioration, which is why the soft wash method is the industry-correct approach.
Job time depends on the scope of work. A driveway or patio typically takes 1–2 hours. A full house exterior wash ranges from 2–4 hours. Larger estates or multi-surface jobs may take a full day. We'll give you a realistic time estimate when we quote the job so you can plan accordingly.
Not necessarily. We need access to an exterior water source (outdoor hose bib) and the areas being cleaned. Many clients in Portola Valley give us gate access codes and aren't home during the service. We'll take before-and-after photos and send them to you upon completion. We do recommend being available for a final walkthrough if possible.
Yes, in most cases. Fresh oil stains respond very well to professional pressure washing with a degreaser pre-treatment. Old, deeply set stains may lighten significantly but not disappear entirely — we'll tell you what to expect on your specific driveway before we start so there are no surprises. We never guarantee 100% removal of extreme set-in staining, but results are typically dramatic.
Yes. We serve the full Peninsula and South Bay, including Woodside, Menlo Park, Palo Alto, Redwood City, Atherton, Los Altos, and beyond. Larger jobs outside our primary service area may be accommodated — give us a call and we'll let you know if we can make it work.

Portola Valley sits in the foothills of the Santa Cruz Mountains, surrounded by oak woodland, redwood groves, and bay laurel. It's one of the most beautiful communities on the Peninsula — and one of the most challenging environments for home exteriors. The combination of shade, coastal moisture, and heavy organic debris creates near-perfect conditions for algae, moss, lichen, and mold to take hold on rooftops, driveways, decks, and siding. Standard cleaning methods don't touch biological growth at the root, which is why professional pressure washing and soft washing are not optional maintenance items for Portola Valley properties — they're essential ones.
Willow Wash LLC provides residential and commercial pressure washing in Portola Valley with an approach built around doing the job correctly rather than quickly. That means surface-appropriate pressure levels, the right chemical dilutions, proper dwell times for soft wash treatments, and thorough rinsing that doesn't leave detergent residue on your landscaping or hardscape. Whether you're preparing a home for sale, refreshing a property you've owned for years, or maintaining a recurring schedule on a large estate, we bring the same level of care and professionalism to every job.
Our service area extends throughout San Mateo County and Santa Clara County, with regular work in Woodside, Menlo Park, Palo Alto, Atherton, Los Altos, and the greater South Bay. Portola Valley clients benefit from our familiarity with the microclimate — we understand what grows here, what stains here, and what cleaning chemistry works best against Peninsula-specific biological growth. That local knowledge translates directly to better results and longer-lasting cleanliness between service visits.
If your driveway is stained, your roof has black streaks, your deck is slippery with algae, or your home's exterior has lost its original color under a layer of grime and oxidation, the solution is a call or a click away.
