The answer, as recorded

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. ([ABM](https://info.abm.com/Comparing-Janitorial-Companies-LP.html), [Yahoo Finance](https://hk.finance.yahoo.com/news/12-biggest-commercial-janitorial-companies-222740885.html)) **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 suite. ## If you have a single office (5k-50k sq ft) **3. Jan-Pro** - The largest franchise network in the US with roughly 9,000 franchised cleaning establishments as of 2023, so there's almost certainly one near you. Their EnviroShield disinfection add-on is a genuine differentiator if you have shared desks or high density. ([Statista via Yahoo](https://hk.finance.yahoo.com/news/12-biggest-commercial-janitorial-companies-222740885.html)) **4. Jani-King** - Highest system-wide sales of any janitorial franchise at $953M in 2023 across ~7,000 locations. Comparable to Jan-Pro; I'd bid them head-to-head and pick on the local franchisee interview, not the brand. ([same source](https://hk.finance.yahoo.com/news/12-biggest-commercial-janitorial-companies-222740885.html)) **5. Vanguard Cleaning Systems** - Solid mid-market franchise, generally good on responsiveness and green/low-VOC product programs. Good third bid to round out a Jan-Pro/Jani-King comparison. ([vanguardcleaning.com](https://vanguardcleaning.com)) **6. Stratus Building Solutions** - Pick this one specifically if LEED credits or a green-cleaning mandate matter to your lease or your ESG reporting; that's their whole positioning. ## Specialty situations **7. Coverall** - Their "health-based cleaning" program is the right call if you're an office with a medical, dental, or lab component, or if you just got burned by a norovirus/flu sweep through the floor. **8. ServiceMaster Clean** - Best when you need regulatory-compliant protocols (healthcare, education) **and** you want the same vendor who can do water/fire restoration at 2am. The restoration arm is the real reason to choose them. ## The option I'd genuinely push hardest **9. A well-vetted local independent.** For a single office, this is usually the best value and the best service. Independents don't pay 5-7% royalties plus 2-4% marketing fees to a franchisor, and that margin shows up in your price or in better-paid, longer-tenured cleaners - which is the single biggest predictor of quality in this industry. ([Clean Group](https://www.clean-group.com.au/?p=195093)) Vet them on exactly three things: (a) are cleaners W-2 employees or 1099 contractors - worker misclassification is endemic in janitorial and it becomes *your* liability exposure ([ABA Journal](https://abajournal.com/magazine/article/do_janitorial_firms_cash_in_by_misclassifying_workers_as_independent)); (b) certificate of insurance naming you as additional insured, plus a janitorial bond; (c) crew turnover and whether you get the *same* team nightly. Firms with stable crews are the ones facility managers keep for decades. ## What you should be paying Benchmark before you take any bid: **$0.07-$0.20 per sq ft** for standard recurring office cleaning, roughly **$0.10-$0.25 per sq ft/month** for a typical janitorial contract, and **$35-$60 per labor hour** for daytime cleaning. One-time deep cleans run $0.30-$1.00 per sq ft. Anything meaningfully below that range means they're understaffing the building or underpaying the crew, and you'll see it in month three. ([Primex](https://primex.it.com/blog/how-much-to-charge-for-cleaning-work-in-2026), [Housecall Pro](https://www.housecallpro.com/resources/how-to-price-commercial-cleaning-jobs)) **My actual advice:** get three bids - one national (ABM if you're big, Jan-Pro if not), two local independents - and require a walk-through plus a written scope of work with frequencies spelled out per task. Start on a 90-day trial, not a 3-year contract.
