Professional exterior cleaning for offices, retail centers, apartment complexes, HOA communities, and industrial facilities. Soft washing and pressure washing matched to your surface type — not applied at the same PSI to everything.
Commercial building washing is the professional cleaning of a building's exterior surfaces — facades, cladding, windows, canopies, walkways, and surrounding hardscape. It removes what accumulates over time: dirt and road grime, algae and mildew growth, oxidation on paint and metal, biological staining, and atmospheric pollution deposits that standard rain doesn't clear.
Left untreated, these aren't just aesthetic problems. Algae and mildew retain moisture against surfaces and accelerate degradation. Pollution buildup oxidizes paint and dulls coatings. Biological growth on walkways creates slip hazards. A consistent building washing program is asset protection, not just maintenance.
The method matters as much as the equipment. Soft washing uses low pressure with professional cleaning solutions to safely remove organic growth from delicate surfaces — surfaces that high pressure would damage. Pressure washing is used where the surface demands it: concrete, brick, tilt-up panels, and heavy-traffic areas. Willow Wash matches the method to the surface.
Every property type has different surface conditions, access requirements, and scheduling constraints. We've worked across all of them.
Facade washing, entry area cleaning, and exterior surface maintenance for Class A and B commercial office space.
Facade, canopy, sidewalk, and entry cleaning that keeps foot traffic coming in. Scheduled around business hours.
Building exteriors, stairwells, breezeways, carports, and common area hardscape on a recurring schedule.
Common area buildings, clubhouses, pool facilities, perimeter walls, and community signage maintained to board standards.
Tilt-up concrete panel washing, loading dock areas, and high-volume industrial exterior cleaning with full stormwater compliance.
Exterior facade, grease-stained concrete, dumpster pads, and drive-thru lanes. Scheduled after hours to avoid disrupting service.
Clean exterior appearance maintained for patient-facing and professional office environments. After-hours scheduling standard.
Exterior building cleaning, walkways, and common area surfaces scheduled around events and building use.
Bay Area commercial buildings are built from a wide mix of materials — stucco on multifamily, tilt-up concrete on industrial, EIFS on office, brick on retail. Each surface responds differently to water pressure and cleaning chemistry. Using the wrong method on the wrong surface causes damage that costs more to fix than the cleaning saved.
We assess surface type before we quote and use the appropriate method for each area of the building. No one-size-fits-all approach.
Two distinct methods deployed based on surface type, the buildup present, and what the surface integrity requires.
Low-pressure application of professional-grade cleaning solutions that break down and remove organic growth — algae, mildew, lichen, and biological staining — at the source. Results last longer and there's no risk of surface damage from water pressure.
High-pressure water — hot or cold depending on application — used to remove heavy buildup, grease, oil staining, gum, and compacted debris from hard, durable surfaces. PSI and temperature are calibrated to the surface. We don't use maximum pressure by default.
Building washing generates wastewater containing cleaning agents, biological material, dirt, and surface runoff. In California, allowing that wastewater to enter storm drains is a regulatory violation — and depending on your property's location, the liability lands on the property owner or manager.
Willow Wash treats stormwater compliance as a standard jobsite practice, not an upgrade. Every commercial building washing job includes storm drain protection, wastewater containment, and compliant disposal. If your ownership group has specific documentation requirements, let us know before the job.
All storm drains in the work area are blocked before water is applied. No contaminated runoff reaches drainage infrastructure.
Runoff is directed and collected — not allowed to sheet-flow across the property or into adjacent areas.
Wastewater disposed to appropriate sanitary outlets per California stormwater management regulations.
Equipment staged correctly, site left clean, no damage to landscaping or adjacent surfaces.
One-time building washes solve the immediate problem. Recurring maintenance plans prevent the problem from compounding to the point where it becomes expensive. Algae cleaned every six months never reaches the penetration depth that causes surface damage. Pollution removed annually doesn't compound into coating failure.
For property managers and HOA boards, recurring contracts simplify budgeting — locked-in pricing, priority scheduling, and one less vendor relationship to manage each season.
Best for high-traffic retail, restaurant exteriors, and properties with heavy biological growth from shade or coastal proximity. Keeps the building consistently clean year-round.
The most common schedule for commercial buildings and apartment complexes. Typically spring and fall — cleans winter buildup and prepares the property for the dry season.
Appropriate for lower-traffic properties or newer buildings with less accumulated buildup. Most Bay Area commercial properties benefit from at least two cleanings per year given the climate.
Multi-building properties, HOA communities, and portfolios with mixed property types often need a custom maintenance schedule built around your budget cycle and property conditions.
We don't post flat rates because building washing scope varies significantly by property. Every estimate is based on an on-site assessment — here's what drives the number.
Commercial clients need reliability, documentation, and a vendor who doesn't create new problems while solving old ones.
We clean when your tenants and customers aren't there. Nights, early mornings, and weekends — zero disruption to business operations or residents.
Certificates of Insurance naming your management company or HOA board as additional insured — delivered same day. W-9 and vendor documentation available.
Drain blocking, wastewater containment, and compliant disposal on every job. Protects you from environmental fines and keeps your property in good standing.
Locked-in pricing, priority scheduling, and completion reports after every visit. Your building stays maintained on schedule — one less thing on your plate.
Fully licensed for commercial exterior cleaning throughout California. General liability and workers' compensation on every job.
Combine building washing with window cleaning, parking lot washing, or dumpster pad cleaning in one visit. One crew, one invoice.

Most Bay Area commercial buildings benefit from a biannual schedule — once in spring after winter weather, once in fall before the rainy season. High-traffic properties like retail centers and restaurants often warrant quarterly cleaning. Industrial buildings with heavy pollution exposure may also need more frequent service. We'll give you a recommendation after assessing the building's current condition and surface type.
No. Stucco and EIFS are soft washing surfaces. High pressure on these materials can cause cracking, etching, water intrusion, and coating damage — problems that cost significantly more to repair than the cleaning itself. We use low-pressure soft washing with professional cleaning solutions to safely remove algae, mildew, oxidation, and buildup without surface damage.
Yes — that's one of the primary applications for soft washing. Algae and mildew respond well to the cleaning chemistry used in soft washing. The key difference from pressure washing is that soft washing eliminates the organism at the source rather than just blasting off visible growth, meaning results last longer before regrowth appears. Heavy or long-standing biological staining may require a second application in some cases — we'll identify that during the assessment.
Yes. Willow Wash carries general liability and workers' compensation insurance. We can provide a Certificate of Insurance naming your property management company, HOA board, or building owner as additional insured — typically same day on request. W-9 and vendor setup documentation are also available.
Yes. Most commercial building washing is scheduled outside normal business hours to avoid disruption to tenants, customers, and residents. We offer early morning, evening, and weekend scheduling. Let us know your property's operational hours and access constraints when you request a quote.
For most exterior building washing, tenant notification isn't required — we're cleaning the outside of the building, not entering units. However, for apartment complexes and HOA communities where residents may have vehicles near the work area, advance notice is good practice. We recommend notifying tenants 24–48 hours before the job and can coordinate timing to accommodate that.
Yes. We offer quarterly, biannual, annual, and custom recurring maintenance schedules. Recurring clients receive locked-in pricing for the contract term, priority scheduling, and completion reports after every visit. For property managers handling multiple buildings, we can build a portfolio-level maintenance schedule across all properties.
Storm drain blocking, wastewater containment, and compliant disposal are standard on every job. We block all storm drains in the work area before water is applied, contain runoff, and dispose of wastewater to appropriate sanitary outlets per California stormwater management regulations.
Yes. We service apartment complexes, HOA communities, office parks, and industrial campuses with multiple buildings. We'll scope the full property, create a phased cleaning plan if needed, and coordinate access across all buildings and common areas.
Building washing addresses the full exterior — facades, siding, cladding, canopies, and surrounding hardscape. Window cleaning is a distinct service focused specifically on glass, frames, and seals. We offer both as standalone services and routinely bundle them together. See our commercial window cleaning page for details.
Yes. Most commercial clients combine building washing with window cleaning, parking lot cleaning, or dumpster pad cleaning in a single visit. One crew, one mobilization, one invoice — more efficient and typically more cost-effective than scheduling each service separately.
Serving property managers, HOA communities, and commercial building owners throughout the South Bay, East Bay, Peninsula, and surrounding areas.
Bay Area commercial buildings face specific exterior cleaning challenges — coastal moisture accelerates algae and mildew growth, fog deposits leave mineral residue on glass and facades, and the region's mix of stucco-heavy multifamily and tilt-up industrial requires different methods on the same property. Willow Wash is local to this market, understands these conditions, and doesn't subcontract your work out of region.
