Willow Wash delivers professional exterior cleaning for Bay Area homeowners — house washing, pressure washing, window cleaning, gutter cleaning, and solar panel cleaning. Done right. Every time.
Bay Area weather — coastal fog, summer dust, pollen, and winter rains — leaves a relentless layer of dirt, algae, mold, and mineral buildup on every exterior surface of your home. Left unchecked, this buildup doesn't just look bad. It degrades surfaces, reduces solar panel output, clogs gutters, and drives up maintenance costs over time.
Willow Wash provides professional residential exterior cleaning throughout San Jose and the greater Bay Area. We match the right method to every surface — soft washing for siding and rooflines, pressure washing for concrete and hardscape, pure water window cleaning for streak-free glass. No shortcuts. No guesswork.
The result is a clean, well-maintained home that holds its value and makes the right impression.
Five focused services, each matched to the right method and equipment. No filler, no upsells you don't need.
Moss, algae, and lichen don't just make your roof look bad — they actively break down shingles and tiles, shortening your roof's lifespan and voiding some manufacturer warranties. Our soft wash process kills growth at the root and removes staining without the high-pressure water that damages roofing materials. Protect your roof now and avoid a far more expensive replacement later.
Oil stains, tire marks, and ground-in grime make even a well-maintained home look neglected. We use professional-grade pressure washing to blast away buildup from driveways, walkways, patios, and concrete surfaces — restoring them to a clean, uniform finish. Fast, effective, and one of the highest-impact upgrades you can make to your home's exterior.
Streak-free windows make a noticeable difference — more natural light inside, a sharper appearance outside. We clean residential windows to a spotless finish using professional techniques that protect glass and frames. Whether it's a single-story home or a multi-level property, we handle it safely and efficiently.
Clogged gutters cause water to back up against your roofline and foundation — leading to costly damage that's entirely preventable. We clear out leaves, debris, and buildup so your gutters flow freely and your home stays protected through every season. Most homeowners don't think about their gutters until there's a problem. We help you stay ahead of it.
Dirty solar panels lose efficiency — sometimes significantly. Dust, pollen, and bird droppings accumulate on panel surfaces and reduce your system's output, costing you money every month. We clean solar panels safely and thoroughly, helping your system perform at the level you paid for. Especially important in the Bay Area where dust and debris build up year-round.
Every residential job follows the same proven process — no shortcuts, no surprises.
We walk your property, evaluate every surface, identify problem areas, and determine the right method for each.
We pre-water landscaping, cover delicate plants, move patio furniture, and protect anything that shouldn't get wet.
Eco-friendly detergents and surfactants are applied to break down organic growth, oil, and embedded stains before rinsing.
Pressure washing for hard surfaces, soft washing for siding and rooflines. The right method for every material.
We inspect every surface with you. If anything isn't right, we re-clean it on the spot. The job isn't done until you say so.
We're not a franchise. We're a local crew that treats your property the way we'd treat our own.
If you're not happy with any part of the job, we come back and re-clean it at no charge. If we still can't make it right, we'll refund you. That simple.
We never use one PSI for everything. Concrete gets high-pressure. Siding gets soft washed. Solar panels get pure water. Every surface is treated according to what it actually needs.
Biodegradable detergents. Water-smart methods. Full stormwater compliance. We protect your landscaping, your pets, and California's waterways on every single job.
In-person estimates, direct communication, no call centers. You talk to the people who actually clean your home. We know Bay Area properties because we live here.
We carry full liability insurance and comply with all California licensing requirements. Your property is protected from the moment we arrive.
Early mornings, weekends, and same-week availability. We work around your schedule — not the other way around. Most quotes delivered within 24 hours.
Free in-person estimates. No hidden fees. Most Bay Area properties quoted within 24 hours.
Soft washing uses low pressure (under 500 PSI) combined with biodegradable cleaning solutions to safely clean siding, stucco, and painted surfaces. Pressure washing uses high pressure (1,500–4,000 PSI) for hard surfaces like concrete driveways and walkways. We use both on most residential jobs — matched to each surface. Using high pressure on siding or stucco is one of the most common ways amateur operators cause damage.
High-pressure washing on a roof is exactly what causes damage — it strips granules from asphalt shingles, cracks tiles, and forces water under seams. We never use high pressure on roofs. Our soft wash process applies biodegradable cleaning solutions at low pressure to kill moss, algae, and lichen at the root. The growth dies and rinses away naturally, with no risk to your roofing material. This is the method recommended by most roofing manufacturers and industry standards.
Most Bay Area homes benefit from gutter cleaning once or twice a year — typically in late fall after leaves have dropped, and again in early spring. Homes with mature trees nearby or in heavily wooded areas may need service more frequently. Clogged gutters are one of the leading causes of foundation and fascia damage, so this is one service worth staying on top of.
Studies show that dirty solar panels can lose anywhere from 15% to 25% of their output depending on the level of soiling and climate conditions. In the Bay Area, where dust, pollen, and bird activity are consistent year-round, the impact is real and measurable. For most homeowners with a standard residential system, that loss translates directly to higher utility bills. Annual or bi-annual cleaning is typically enough to maintain near-peak performance.
Yes. Rain water itself is relatively clean — it's the mineral deposits, salt residue, and environmental grime already on the glass that cause streaking after rain. A professional window clean removes that buildup, so post-rain windows actually look better than before they were cleaned. We recommend scheduling window cleaning just before or after the rainy season for the best long-term result.
Single-service jobs like a driveway cleaning or gutter cleaning typically take 1–2 hours. Roof cleaning on a standard single-family home runs 2–3 hours depending on pitch and condition. If you're bundling multiple services in one visit — which most customers do — plan for 3–5 hours depending on property size. We give you a time estimate upfront so you can plan your day.
Yes. We use biodegradable, plant-safe, and pet-safe detergents on every job. Before we start, we pre-water your landscaping and cover any sensitive plants.
