🌿 Spring cleaning season is here — book your post-rain exterior clean before the schedule fills up
Every Bay Area rainy season leaves a residue — algae, mud stains, mold, and pollen buildup on every exterior surface. Willow Wash restores your home's appearance and protects surfaces before the summer heat sets in.
From October through April, Bay Area homes take a beating. Months of rain, wind, and organic debris leave behind a layer of algae growth on north-facing surfaces, mud splash-back on siding and fences, mold starting to form in shaded corners, and pollen coating every horizontal surface as spring arrives.
Left uncleaned, this isn't just cosmetic. Algae and mold colonies expand through summer, breaking down paint and surface sealers. Pollen and organic debris in gutters create the foundation for the next season's blockage. Mud stains on concrete oxidize and become permanent without treatment. Spring is the window — clean now before the summer heat bakes everything in.
Willow Wash handles the full post-rainy season reset: pressure washing, soft washing, window cleaning, gutter flushing, and roof treatment — all in one coordinated visit. We document every surface before and after so you can see exactly what was done.
Every surface that took a hit this rainy season — we clean it. One call, one crew, full property reset. Bundle multiple services for the best value.
Low-pressure soft wash treatment removes algae, mold, mildew, and winter grime from stucco, siding, brick, and painted surfaces — without damaging paint or caulk. The right method for every surface type.
Winter rain drives tire marks, oil, and mud deep into concrete. Spring pressure washing lifts embedded stains before they oxidize permanently, restoring your driveway, walkways, and patio surfaces to a clean baseline.
Spring pollen and rain water spots leave Bay Area windows coated in a haze that no amount of sunlight improves. We clean interior and exterior glass, screens, tracks, and sills — streak-free and documented.
Six months of moisture creates ideal conditions for moss, lichen, and algae to establish on Bay Area roofs. Spring soft wash treatment kills active growth and applies a residual treatment to prevent regrowth through the dry season.
After a wet winter, gutters collect compacted debris and silt that downspouts can't flush on their own. Our spring gutter service clears channels and flushes downspouts so your system is ready for the next season.
Spring pollen is the single biggest driver of solar output loss in the Bay Area. A professional panel clean in April or May recovers lost efficiency before the long dry season — the highest-ROI cleaning service on your property.
One coordinated visit covers your entire property. We assess every surface, apply the right method for each one, and document everything from start to finish.
Tell us what surfaces you need cleaned and we'll provide a clear, itemized quote. Bundle multiple services for the best per-service rate.
Before starting, we walk the property and identify the right cleaning method and solution for every surface — no one-size-fits-all pressure washing.
We work through every service systematically — roof to concrete, windows to gutters. Your landscaping is protected throughout and cleaned up after.
Before and after photos for every surface are sent directly to you after the job. A complete record of what was cleaned and what it looked like.
Most Bay Area homes need more than one service after a wet winter. Bundling saves you money compared to booking each service separately and gets everything done in a single visit.
We're a local Bay Area team — not a franchise. The same crew that quotes your job cleans your property, and you see documented proof of every surface we touched.
Soft washing for stucco and siding, high pressure for concrete, gentle technique for solar panels and windows. We don't use one method for everything — surface damage from wrong-pressure washing is common and avoidable.
Willow Wash LLC carries full general liability insurance on every job. Your property is protected, your HOA is satisfied, and you're working with a legitimate business — not an unlicensed pressure washer from Craigslist.
Before and after photos are standard on every service — not an upsell. You'll see exactly what was cleaned, what products were used, and the condition of each surface after we finish. No guesswork, no taking our word for it.
We're a two-person crew based in San Jose. We don't subcontract your job to rotating workers — the same people who quoted your property are the ones who show up and clean it.
We use biodegradable, plant-safe, and pet-safe detergents on every job. Pre-watering landscaping before application and full California stormwater compliance on every service — no harmful runoff into storm drains.
No arrival-day price changes. No hidden fees for "difficult access" or extra equipment. What we quote is what you pay. For bundled services, we price transparently so you see the savings clearly.
Algae, mold, and stains are easiest to remove now. Once summer heat bakes them into your surfaces, cleaning becomes harder and more expensive. Get your free estimate today.
The ideal window is April through May — after the last significant rains have passed and before summer heat arrives. Cleaning during this window gives algae and mold treatments time to work while surfaces are still accessible, and removes pollen and storm residue before it bakes in. Booking earlier in April is better as schedules fill quickly once the weather stabilizes.
Pressure washing uses high-pressure water to blast debris off hard surfaces like concrete, pavers, and brick. Soft washing uses low-pressure application of biodegradable cleaning solutions to kill and remove organic growth — algae, mold, mildew — from delicate surfaces like stucco, siding, roofing, and painted wood. Using high pressure on the wrong surface causes paint stripping, surface etching, and water intrusion. We assess every surface before starting and use the correct method for each one.
No. We use biodegradable, plant-safe detergents on every job. Before applying any cleaning solution near landscaping, we pre-water plants and cover sensitive areas. We also follow California stormwater compliance guidelines — all runoff is managed responsibly. Your garden, lawn, and any potted plants near work areas are fully protected throughout the job.
Stucco should never be high-pressure washed — it is a porous material that absorbs water and can be damaged, cracked, or have paint stripped by high-pressure application. We use a low-pressure soft wash method on all stucco surfaces, which safely removes algae, efflorescence, and dirt without any risk to the material. The majority of Bay Area homes are stucco — this is standard practice for us.
Once a year is sufficient for most Bay Area homes — and spring is the optimal timing because you're cleaning off six months of accumulated rainy season residue right before summer. Homes under heavy tree canopy, with north-facing walls that don't see direct sun, or in high-pollen areas may benefit from twice-yearly cleaning. We'll give you an honest assessment after the first visit.
Yes — bundling is encouraged and comes with discounted pricing compared to booking services individually. Our most popular spring combination is house soft wash + driveway pressure wash + window cleaning + gutter flush. You can add roof treatment and solar panel cleaning to the same visit. One crew, one appointment, full property covered.
No. As long as we have access to your exterior and a water source, you don't need to be present. We'll send before and after photos when the job is complete. Most of our clients are at work during the service and come home to a clean property and a full photo report in their inbox.
Significantly. Exterior cleaning is consistently cited by real estate agents as one of the highest-ROI pre-sale improvements. A full spring clean — pressure washing, soft wash, window cleaning — removes years of weathering and biological staining that makes a property look older and less maintained than it actually is. Spring is also peak home selling season in the Bay Area, making timing ideal.
Yes. We work with HOAs, property managers, and multi-unit complexes throughout the Bay Area for post-rainy season exterior cleaning. We provide service documentation for HOA records, can coordinate multi-building scheduling, and offer recurring annual contracts for communities that want consistent spring and fall exterior maintenance on autopilot.

The Bay Area's rainy season creates a predictable but serious accumulation problem. From October through April, the combination of wet conditions, limited sunlight on north-facing surfaces, and organic material from the region's dense tree canopy creates ideal conditions for algae, mold, and mildew to establish on exterior surfaces. Stucco walls develop green biological staining. Concrete driveways accumulate mud, tire marks, and oil that rain alone cannot remove. Wood fences and decks develop surface mold in shaded areas. And as spring arrives, pollen from the Bay Area's oak, juniper, and grass pollination season coats windows, solar panels, and every horizontal surface in a layer of yellowish haze.
Our spring exterior cleaning process is designed to address all of it in a single coordinated visit. House soft washing removes biological growth from stucco and siding using low-pressure application of biodegradable cleaning solutions — the only safe method for painted and porous exterior surfaces. Driveway and concrete pressure washing lifts embedded stains before summer heat oxidizes them permanently. Window cleaning removes pollen film and rain spots from glass, screens, tracks, and sills. Roof soft wash treatment kills active moss and algae growth before the dry season allows it to spread. And a gutter flush clears compacted debris from the winter's final storms before fall buildup begins.
