ABM Industries** - The one I'd call first for anything at scale. Founded 1909, ~$3B market cap, and critically it's a **direct employer**, not a franchise - W-2 janitorial staff, not subcontracted franchisees. That means consistent training, real liability coverage, and accountability that rolls up to one company. They also bundle HVAC, engineering, parking, and landscaping, so you can consolidate facilities vendors.

ISS or Sodexo** - Worth bidding against ABM if you're a corporate campus and want integrated facility management (cleaning + food + reception) under one contract.
