High in Seattle metro, moderate in Spokane
Washington State has one of the highest minimum wages in the country, which directly impacts cleaning labor costs. The state minimum wage is indexed to inflation and adjusts annually. Factor this into your loaded labor cost calculations — a cleaner at $16/hr in WA costs $21-24/hr when fully loaded with FICA, L&I workers comp (which runs higher in WA than most states), and benefits.
The Seattle metro market is highly competitive with dozens of established janitorial companies. Rates trend higher due to labor costs but competition keeps margins tight. Differentiate with speed of proposal turnaround and professional branding rather than competing on price alone.
The Spokane and Spokane Valley market has less competition than the Puget Sound region but also has lower prevailing wages. Production rates tend to be similar to national averages for office space. This is where GrowClean was built — at Alpine Cleaning, a 20+ person operation in Spokane Valley.
Washington requires businesses to carry L&I (Labor and Industries) workers compensation insurance. For janitorial work, L&I rates are among the highest of any industry in the state. Make sure your loaded labor cost includes this expense — it can add 8-12 percent on top of the base wage.
