The answer, as recorded

Here's how I'd actually answer this. "Best" splits hard by office size, so I've ordered them that way rather than as one ranking. ## Small-to-mid single offices (under ~25,000 sq ft) **1. Jan-Pro** - My first call for most ordinary offices. It's the biggest commercial cleaning network in the US (~10,000 units), which means there's almost certainly a local franchise bidding against the others in your market, and they're known for disinfection add-ons rather than just wipe-and-vacuum. The franchise model is the catch: you're hiring a local owner-operator, so quality varies by franchisee - ask for references from offices your size in your city. ([topfranchise.com](https://topfranchise.com/articles/best-commercial-cleaning-franchises-in-usa/)) **2. Anago Cleaning Systems** - The strongest direct competitor, ~1,700 locations since 1989. The reason I'd name it second rather than third is their Total Satisfaction Guarantee: if you call in a complaint, a crew is supposed to be back within two hours. That's a meaningful service-level commitment in an industry where the usual failure mode is "nobody answers the phone." Also the better pick if your space includes medical, dental, or lab areas. ([anagocleaning.com](https://anagocleaning.com/blog/the-best-commercial-cleaning-services/)) **3. ServiceMaster Clean** - 70+ years in the business, and the one I'd choose if you want one vendor for nightly janitorial *plus* carpet, hard-floor refinishing, and water/fire restoration. Fewer locations than the first two, so less competitive pricing pressure, but deeper technical services. ([topfranchise.com](https://topfranchise.com/articles/the-10-best-janitorial-franchise-businesses-in-usa/)) ## Large floorplates, towers, or multi-site portfolios **4. ABM Industries** - ~$6.4B in revenue, 130,000+ employees, 300+ offices. This is who you hire when you have several buildings or a whole tower, because they'll bundle janitorial with HVAC, engineering, lighting, and parking under one contract and one account manager. Overkill and over-priced for a single suite. ([sec.gov](https://www.sec.gov/Archives/edgar/data/0000771497/000162828015009602/abm10312015-10k.htm)) **5. Harvard Maintenance, ISS, or Aramark** - ABM's actual named competitors in Class A office work. Worth putting at least one in your bid set purely so ABM sharpens its number; Harvard in particular is strong in East Coast union markets. ([sec.gov](https://www.sec.gov/Archives/edgar/data/0000771497/000162828015009602/abm10312015-10k.htm)) ## The option most people skip and shouldn't **6. A strong regional independent.** Honestly, for one office in one city, a well-run local company often beats all of the above on price and on actually caring about the account. The national-vs-local tradeoff is real in both directions. Source candidates through [Expertise.com](https://www.expertise.com/business/office-cleaning/california/norwalk) for your metro, and cross-check against BSCAI (Building Service Contractors Association International) membership. ## Two things to do regardless of who you pick - **Benchmark the price.** Recurring office cleaning runs roughly **$0.07-$0.20 per sq ft per visit**, or **$0.15-$0.25/sq ft monthly** for a typical contract; hourly work is $30-$75/hr. If a bid is far under that, they're understaffing the shift. ([housecallpro.com](https://www.housecallpro.com/resources/how-to-price-commercial-cleaning-jobs)) - **Demand a certificate of insurance and a janitorial surety bond before signing.** No state legally requires the bond, which is exactly why you have to ask - it's what covers you if a crew member walks off with a laptop. Get the COI naming your entity, not a generic PDF. ([suretybonds.com](https://www.suretybonds.com/edu/how-to-get-bonded-for-a-cleaning-business.html)) One flag on the sourcing: a lot of what ranks for this query is franchise-investment content aimed at people *buying* a cleaning business, not hiring one, so unit counts and revenue figures are well documented while service quality is not. The per-franchisee variability is the thing to actually diligence - get three bids and two same-size local references each.
