San Mateo's Exterior Cleaning Company

Professional Pressure Washing & Exterior Cleaning in San Mateo, CA

San Mateo sits right between the Bay and the hills, which means your property gets the worst of both worlds — bay moisture on one side, tree debris and shade on the other. From historic streets in Baywood and Aragon to newer townhomes near Bay Meadows and the Hillsdale Caltrain station, Willow Wash keeps San Mateo exteriors clean, bright, and protected.

Stucco homes along El Camino Real collect traffic film and grime. Bayside neighborhoods like Shoreview and North Shoreview deal with algae, mildew, and salt air. West-of-Alameda homes up toward Laurelwood and the Highlands fight moss on shaded roofs and slippery pathways after winter storms. We match the cleaning method to each surface and micro-climate so you get a deep clean without damage.

Every detergent we use is biodegradable and safe for kids, pets, and landscaping. We pre-water plants, control runoff so it stays out of San Mateo storm drains, and rinse everything down when we are finished. Most San Mateo properties are quoted within 24 hours. Call 📞 (669) 254-7406 or request a visit online anytime.

FAQ

Pressure Washing Questions — San Mateo

Most San Mateo residential pressure washing projects run between $150 and $400 depending on size, access, and surfaces. Driveway-only jobs often start around $100–$150. Full exterior house washing is usually $250–$400, and roof cleaning typically ranges from $300–$600. Commercial work is quoted per square foot after an on-site visit.
Yes. Properties near Highway 101, Highway 92, and the bay collect extra exhaust film, moisture, and mildew. We use the right detergents and dwell times to remove that buildup from concrete, siding, and stucco without damaging the surface.
We work everywhere in San Mateo, including Baywood, Baywood-Aragon, San Mateo Park, Hillsdale, Beresford Park, Fiesta Gardens, Parkside, Shoreview, North Shoreview, San Mateo Village, Hayward Park, Downtown San Mateo, and surrounding areas.
Yes. Willow Wash is fully licensed and insured for residential and commercial exterior cleaning throughout San Mateo County and the Bay Area. We carry general liability insurance and can provide certificates of insurance for HOAs, property managers, and commercial clients.
Once a year works for many San Mateo homes. Properties under heavy tree cover, near the bay, or in shaded hillsides may benefit from cleaning every 6–12 months because moss, algae, and mildew grow faster. During your estimate we will give a schedule that fits your property and budget.
No. Our detergents are biodegradable and used at proper dilutions. We pre-wet plants, control runoff, and rinse thoroughly after cleaning. We also avoid letting wash water enter storm drains whenever possible to help protect San Mateo’s waterways.
Yes. For properties near Downtown San Mateo, Hillsdale, Bay Meadows, and along El Camino Real, we often schedule early mornings, evenings, or weekends to avoid peak hours and parking pressure. We are available 24/7 with no extra charge for off-hours work.
Most projects can be scheduled within a few days, but spring and early summer fill up quickly. If you are planning around photos, open houses, or a big event, booking one to two weeks in advance is ideal. Rush and short-notice cleanings are often available — just ask.
