This metro spans IL, IN. Procurement rules differ by state line — we handle both sides.
Who cleans your building
In Chicago the work is performed either by cleaners we employ directly or by a partner contractor we have vetted — insurance certificates verified with the carrier, workers compensation confirmed, background-check process audited against what your state and your district require. You sign one contract with us and we carry the obligation either way. Ask, and we will tell you which it is here before you commit.
Private schools, charters and childcare centres
Not every school in Chicago runs a formal procurement. Independent, parochial and charter schools and childcare centres can usually agree a scope and a start date inside a few weeks. If that is you, a walk-through is the fastest route to a real number.
