COI on request. W-9 ready. Licensed, insured, and documented — so your procurement team can add us to the preferred vendor list without the back-and-forth.
General contractors and project managers need subcontractors who show up properly documented, communicate clearly, and don't create liability problems. That's the standard we hold ourselves to on every commercial engagement.
Willow Wash LLC operates as a California-registered limited liability company. We carry commercial general liability insurance, maintain current workers' compensation coverage, and can furnish certificates with additional insured endorsements to accommodate your contract requirements.
We've completed post-construction and exterior cleaning scopes at facilities totaling hundreds of thousands of square feet in the Bay Area. Our documentation, communication protocols, and invoicing are built to meet the demands of commercial construction workflows.

Final cleans for handover-ready facilities. We remove construction debris, dust, adhesives, paint overspray, and protective films.
Commercial-grade pressure washing for building exteriors, plazas, parking structures, loading docks, and hardscape.
Interior and exterior window cleaning for office buildings, warehouses, industrial facilities, and retail properties.
Low-pressure chemical application for roofs, stucco, EIFS, painted surfaces, and materials that can't tolerate high PSI.
High-volume cleaning for warehouse distribution centers, data center facilities, manufacturing spaces, and industrial parks.
Scheduled cleaning programs for property managers, asset managers, and facilities teams managing multiple locations.
Willow Wash completed a commercial post-construction cleaning engagement at 2222 Qume Drive, North San Jose — a multi-building office campus totaling over 719,000 square feet across four structures.
Services performed included commercial window cleaning, exterior pressure washing, and post-construction office cleaning. The scope required coordination with the general contractor's site schedule and adherence to access and safety protocols across an occupied development site.
This project demonstrates our capacity to execute large-scale commercial scopes with the documentation, communication, and site behavior that GC relationships require.
View Full Project DetailWe've streamlined the onboarding process. Most procurement teams have us set up in their system within 48 hours.
Email us your company's vendor questionnaire, new subcontractor form, or a list of the specific documents your system requires.
We'll pull together your COI with the correct language, W-9, business docs, and any scope letters or safety acknowledgments needed.
We'll review and execute your standard subcontractor agreement or master services agreement. Most are returned within 24 hours.
Once you're set up, send us a scope or RFP for your next project. We'll provide a detailed bid with line-item breakdown.
Commercial construction sites have rules — access protocols, safety requirements, and environmental obligations. We know them and we work within them.
Crew operates in proper PPE for the scope — eye protection, gloves, non-slip footwear, and hi-vis where required. We follow the site-specific safety plan provided by your superintendent.
Before starting any scope, we assess the work area for site-specific hazards — overhead work, proximity to other trades, electrical panels, drainage, and surface sensitivities.
Pressure washing generates wastewater with potential FOG and chemical content. We contain runoff, prevent storm drain discharge, and use licensed haulers where volumes require it.
All cleaning chemicals are matched to the surface and scope. Safety Data Sheets are available for every product used on your site and can be submitted with your pre-job documentation package.
We provide itemized invoices with scope line items, quantities, and project reference numbers. Format can be adapted to match your AP system requirements. Net 15 and Net 30 available.
Yes. Email us your company's legal name, address, and any specific additional insured language your contract requires. We'll coordinate with our carrier to issue the certificate, typically within the same business day for requests submitted before noon.
Coverage limits are confirmed on the certificate itself. Contact us directly at info@willowwashllc.com or (669) 254-7406 and we'll send you a current sample certificate showing the exact limits. If your contract requires specific minimum limits, let us know and we'll verify coverage accommodates your requirements before you proceed.

We completed a multi-building post-construction scope at 2222 Qume Drive in North San Jose — a four-building, 719,000+ square foot campus — working within a general contractor's site schedule and access protocols.

We serve the full San Francisco Bay Area — South Bay (San Jose, Santa Clara, Sunnyvale, Cupertino, Milpitas), Peninsula (Palo Alto, Redwood City, San Mateo), and East Bay (Fremont, Hayward, Pleasanton, Walnut Creek). For large commercial scopes, contact us directly and we'll confirm coverage for your specific project location.
We contain wastewater runoff and prevent discharge to storm drains per local stormwater regulations. For scopes generating significant volume or chemical content (e.g., degreaser application), we coordinate licensed hauler disposal. We can provide a written disposal protocol for inclusion in your environmental compliance documentation on request.
We invoice via Jobber and can accommodate Net 15 or Net 30 payment terms for approved commercial accounts. Invoices are itemized by scope line item with project reference numbers. We accept ACH, check, and credit card. If your AP department has specific invoicing format requirements, let us know upfront and we'll match them.
For planned scopes, we typically mobilize within 3–5 business days of executed agreement and confirmed access. For urgent or time-sensitive cleans tied to project milestones or occupancy deadlines, contact us directly — we prioritize commercial clients with active projects and can often mobilize faster for scopes with clear scope definitions.
