Serving Cupertino
Exterior cleaning built for Cupertino properties
Golden State Pressure Washing is based in San Jose and serves Cupertino year-round. We soft wash siding and roofs, surface-clean concrete, and detail everything in between — using eco-friendly, pet-safe products and protecting your landscaping from start to finish.
Homes in Cupertino take a specific kind of weathering: damp shaded mornings that feed moss and algae, dry summers that bake dust and oxidation into siding, and hard water that leaves mineral spotting and efflorescence on stone, stucco and glass. We clean each surface with the method it actually needs — soft washing for stucco and siding, rotary surface cleaning for concrete, no-pressure treatment for roofs, and deionized water for windows and solar panels.
Local housing stock drives the method. Craftsman and ranch elevations need gentle low-pressure work around wood trim, while stucco subdivisions need controlled downstreaming that never forces water behind the finish coat. Shaded lots hold moisture and grow moss and lichen on north-facing roof planes, and hard water leaves efflorescence on stone and mineral spotting on glass. We adjust PSI, GPM, dwell time and detergent strength for each of them.

Reviews
What neighbors say
"Our stucco had green streaks on the whole north side. They soft washed it and it looks like a repaint. Showed up on time, cleaned up after themselves."
"Driveway had 12 years of oil stains. I honestly did not think it would come out. It came out. Fair price and they were careful around my planters."
"Roof was covered in moss under the oaks. No pressure treatment, no broken tiles, and the moss is gone. Booked them for the gutters too."
"Solar production was down noticeably. After the cleaning it went right back up. Easy scheduling and they sent photos when they finished."

Cupertino questions
Pressure washing in Cupertino, answered
How much does pressure washing cost in Cupertino?+
In Cupertino a full house soft wash starts at $289, driveway and sidewalk surface cleaning starts at $169, and roof soft washing starts at $429. Final pricing depends on square footage, stories, roof pitch and how much moss, algae or lichen has taken hold. Every quote is flat and written — never hourly.
Do you soft wash or pressure wash Cupertino homes?+
Both, matched to the material. Stucco, siding, and roofs in Cupertino get low-pressure soft washing — under 100 PSI with downstreamed sodium hypochlorite, algaecide and surfactants. Concrete driveways and walkways get rotary surface cleaning at higher PSI and GPM for an even, stripe-free finish.
Is roof washing safe for Cupertino roofs?+
Yes, when it is done without pressure. We follow ARMA-compliant methods: a no-pressure chemical treatment that kills moss, algae and lichen at the root. Pressure would strip granules from composition shingles and crack the concrete and clay tile common across Cupertino.
Which Cupertino neighborhoods do you serve?+
We work throughout Cupertino, including Rancho Rinconada, Monta Vista, Garden Gate — plus surrounding streets and HOA communities. Travel inside Santa Clara County is included in the quoted price.
Why do homes in Cupertino get black streaks and green growth?+
Cool coastal mornings, tree cover and irrigation overspray keep north-facing walls and shaded roof planes damp long enough for gloeocapsa magma algae, moss and lichen to establish. Hard water in Cupertino also leaves mineral spotting and efflorescence on glass, stone and stucco.
Are your products safe for pets, kids and landscaping in Cupertino?+
Yes. We use biodegradable, eco-friendly detergents, pre-soak and rinse all landscaping, and pets and kids can be back outside as soon as surfaces dry.
Are you licensed, bonded and insured to work in Cupertino?+
Golden State Pressure Washing is licensed, bonded, fully insured and a BBB Accredited Business. Certificates of insurance are available for Cupertino HOAs and property managers on request.
How quickly can I get a quote in Cupertino?+
