NIGP 91081: Window Washing Services

NIGP 91081 Window Washing Services is an Item code under which state and local governments solicit commercial window cleaning—interior, exterior, or both—at municipal buildings, airports, courthouses, libraries, water treatment plants, schools, and university campuses on recurring annual or multi-year contracts. Recent solicitations show demand for comprehensive cleaning of glass, frames, windowsills, mullions, and ledges, often bundled with pressure washing, high-dusting, and specialized services such as atrium or skylight cleaning. The work is performed by facility maintenance departments, airports, and university systems across municipal and county jurisdictions, with issuing bodies ranging from major cities to county school districts to special authorities. Cities of Austin, San Antonio, Fort Worth, and Orlando have posted multiple windows-cleaning solicitations in the past four months; Pinellas County, Florida, reported a two-year incumbent contract value of $220,934.93 ($110,467.47 annually) for approximately 75 facilities. Contracts typically run one to five years with optional renewal periods, pricing is fixed or unit-rate with annual price-adjustment caps (often tied to CPI or 5 percent), and performance includes compliance with prevailing wage ordinances, OSHA standards, and EPA-compliant or Green Seal–certified cleaning products. Local business preferences are common; the City of Austin applies discounts up to 5 percent, and the City of Fort Worth applies a 30 percent small business participation goal. Some jurisdictions—notably the Abraham Lincoln Presidential Library in Illinois and the City of Salem, Oregon—restrict participation to small business or require demonstration of three to five years of prior experience. Insurance requirements typically include general liability ($500,000 to $2,000,000 per occurrence) and workers' compensation.
