Serving Los Altos
Exterior cleaning built for Los Altos properties
Golden State Pressure Washing is based in San Jose and serves Los Altos 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.
Los Altos properties are held to a different standard, and exterior cleaning here is a preservation job rather than a blast-and-go one. We approach estate homes with discreet, protective methods: low-pressure soft washing on painted and stucco elevations, ARMA-compliant no-pressure roof treatments on tile and shake, hand detailing on stone, and deionized pure-water rinsing on glass so nothing dries spotted. Mature landscaping is pre-soaked and rinsed, fixtures and low-voltage lighting are covered, and every technician walks the property with you before the trailer leaves the driveway.
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.

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."

Los Altos questions
Pressure washing in Los Altos, answered
How much does pressure washing cost in Los Altos?+
In Los Altos 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 Los Altos homes?+
Both, matched to the material. Stucco, siding, and roofs in Los Altos 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 Los Altos 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 Los Altos.
Which Los Altos neighborhoods do you serve?+
We work throughout Los Altos, including Los Altos Hills, North Los Altos, Country Club — plus surrounding streets and HOA communities. Travel inside Santa Clara County is included in the quoted price.
Why do homes in Los Altos 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 Los Altos also leaves mineral spotting and efflorescence on glass, stone and stucco.
Are your products safe for pets, kids and landscaping in Los Altos?+
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 Los Altos?+
Golden State Pressure Washing is licensed, bonded, fully insured and a BBB Accredited Business. Certificates of insurance are available for Los Altos HOAs and property managers on request.
Do you offer discreet, white-glove service for Los Altos estate properties?+
Yes. Los Altos estate work is scheduled around your calendar, crews arrive in marked vehicles with uniformed technicians, fixtures and mature landscaping are protected, and we walk the property with you or your estate manager before we leave.
Do you offer military, senior and new-customer discounts?+
Yes — 10% off for Military and Senior Citizens, and 10% off for New Customers. Discounts cannot be combined.
