## The answer, as recorded

Asked on 2026-10-17 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually rank these, with the caveat up front that "best" in this category is mostly about *who shows up at your building*, not the logo on the invoice - most national brands are franchise networks, so you're really hiring a local operator under a national brand.
> 
> ## If you have multiple sites or a large office (50k+ sq ft)
> 
> **1. 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.

> 
> **2. ISS or Sodexo** - Worth bidding against ABM if you're a corporate campus and want integrated facility management (cleaning + food + reception) under one contract. Only makes sense above a certain scale; they're not interested in a 10,000 sq ft sui
