The answer, as recorded

Quick framing before the names: office cleaning is a local-labor business, so there's no national "best" the way there is for software. What you're really picking is a *tier*, and within the tier the specific local operator or franchise owner matters more than the brand on the invoice. Here's who I'd actually name, in the order I'd consider them. ## Large or multi-site portfolios (50k+ sq ft, or several buildings) **1. ABM Industries** - the default first call. Founded 1909, ~$8B annualized revenue, 20,000+ clients, 350+ offices across the US/UK/Ireland. They self-perform janitorial (under "ABM Janitorial Services" / "American Building Maintenance") rather than subcontracting it out, which is the single biggest quality variable in this industry. Best when you need one accountable contract across multiple sites, union-compliant staffing, and real insurance depth. ([ABM SEC filing](https://www.sec.gov/Archives/edgar/data/771497/000095013406023656/f25881e10vk.htm), [investor.abm.com](https://investor.abm.com/node/17876/html)) **2. SBM Management, Aramark, Sodexo, or C&W Services** - worth bidding alongside ABM if you want janitorial bundled into integrated facilities management (HVAC, security, landscaping, reception). You pay a coordination premium; it's worth it if your facilities team is thin, and not worth it if cleaning is all you need. ## Small to mid-size single offices (2k-50k sq ft) This is franchise territory. The brand sets the standards and systems; the *local franchise owner* does the work, so interview them directly. **3. Jan-Pro** - the one I'd shortlist first in this tier. Founded 1995, Alpharetta GA; broad service menu (routine janitorial, carpet and hard-floor care, disinfecting, green cleaning, post-construction) and strong systematization across business offices, medical, financial, and government facilities. Good coverage density in most US metros. ([CB Insights profile](https://www.cbinsights.com/compare/jan-pro-franchising-international-vs-office-pride)) **4. Office Pride Commercial Cleaning Services** - founded 1992, Palm Harbor FL. Consistently the best-reviewed franchise on *retention and reliability* - the mundane thing that actually matters, since the failure mode in this industry is crew turnover, not bad chemicals. Routine janitorial, floor care, deep cleaning, disinfection. ([CB Insights](https://www.cbinsights.com/compare/jan-pro-franchising-international-vs-office-pride)) **5. ServiceMaster Clean** - in business since 1929, franchising since 1952, 900+ franchises in 12 countries. The most mature operation of the group and the one I'd pick if you also want disaster/water-damage restoration from the same vendor. ([franchise.servicemasterclean.com](https://franchise.servicemasterclean.com/franchise-blog)) **6. OpenWorks (O.P.E.N. America)** - founded 1983, Phoenix. Pick these if you want janitorial *plus* pest control, HVAC, lighting, plumbing, handyman, and consumables replenishment on one contract. Effectively light-touch FM for mid-size tenants. ([CB Insights](https://www.cbinsights.com/compare/jan-pro-franchising-international-vs-open-america)) **7. Jani-King** - founded 1969, Addison TX; 120 regional support offices in 10 countries. Enormous footprint, so often the only option in smaller markets. Their real specialty is large venues (stadiums, arenas, ballparks), which makes them stronger on event/surge work than on quiet nightly office routes. ([janiking.com](https://janiking.com/)) **8. Anago Cleaning Systems, CleanNet USA, 360clean** - the second tier of franchises; worth a quote to pressure-test pricing. 360clean in particular leans health-focused/"hygiene-first" protocols, which some medical-adjacent offices want. ([CB Insights](https://www.cbinsights.com/compare/360clean-vs-jan-pro-franchising-international)) **9. A well-reviewed local independent** - genuinely my top recommendation for a single office under ~20k sq ft. No franchise royalty in your rate, the owner often walks the site, and you can usually get the same crew every night. The catch is that you must verify what a franchise gives you for free: general liability and janitorial bond, workers' comp, and E-Verify/I-9 compliance. ## What to actually do Get **three bids in writing** with a line-item scope and frequency schedule. For benchmarking, nightly office cleaning runs roughly **$0.07-$0.20 per sq ft per visit**, monthly contracts around **$0.15-$0.25 per sq ft** at the average, daytime labor **$35-60/hour**, and one-time deep cleans **$0.50-$1.00 per sq ft** - with regional swings of 10-40%. ([HouseCall Pro](https://www.housecallpro.com/resources/how-to-price-commercial-cleaning-jobs), [HomeStars price guide](https://www.homestars.com/cleaning/price-guides/commercial-office-cleaning-cost)) Two things I'd insist on in the contract: a **30-day termination clause** (vendor quality decays after the first quarter more often than it fails up front), and a named **on-site supervisor with escalation contact**. Also ask directly whether the crew is employed or subcontracted - subcontracted labor is where liability and turnover problems concentrate. One caveat on sourcing: searching this term surfaces a lot of low-quality "Top 10 cleaners in [city]" SEO pages with unverifiable ratings, and I'd discount the specific local companies they name. For local vetting I'd use BBB accreditation, your building's property manager (they usually already know who services the building well), and ISSA CIMS certification as a real quality signal.
