The answer, as recorded

Here's how I'd actually answer this. One upfront caveat that matters: office janitorial is a franchise-dominated industry, so the "national brand" you hire is almost always a local franchisee. The brand sets standards, training, and insurance; the franchisee does the work. Vet the local owner as hard as the logo. Also, several of the "top 10" lists that surface for this query are published by the cleaning companies themselves (CleanNet ranks CleanNet #1; Anago publishes a "top companies" list) - I've weighted those down. **The ones I'd actually name, in order:** 1. **ServiceMaster Clean** - my default first call. ~70 years in business, 1,200+ US franchises, and the broadest service menu (nightly janitorial plus carpet, hard-floor, post-construction, disaster/water restoration). If you want one vendor who can handle both the recurring contract and the one-off emergency, this is it. 2. **Jani-King** - the one I'd name for large or multi-tenant buildings. 9,000+ franchisees, 40+ years, and the deepest bench for big square footage and multi-site portfolios where you need consistent standards across locations. 3. **Anago Cleaning Systems** - best fit for mid-size offices on a nightly after-hours schedule. Their differentiator is accountability tech: a client-facing app for requests and issue tracking, plus tiered supervision. Published pricing runs roughly $0.09-$0.22/sq ft, which is a useful sanity check on any bid you receive. 4. **Jan-Pro** - the pick if disinfection is the actual driver (shared desks, high-density floors, post-outbreak). Their EnviroShield electrostatic system is the real product here, not the general janitorial. 5. **Coverall** - strongest in regulated/health-adjacent space. If your office includes a clinic, dental suite, lab, or childcare, their Health-Based Cleaning System is built for that compliance profile. 6. **Stratus Building Solutions** - the one to name if green certification is a procurement requirement or you have LEED/ESG reporting obligations. Green Seal-certified chemicals as the standard offering, not an upcharge tier. 7. **A vetted local independent** - genuinely competitive, and often better. Locals typically give you the owner's cell number and more schedule flexibility; the tradeoff is thinner insurance, less backup staffing when someone quits, and no multi-site consistency. For a single office under ~10,000 sq ft, a good local usually beats a mediocre franchisee. **What to check before signing, regardless of brand:** proof of general liability *and* workers' comp (not just "bonded and insured" on the website), whether staff are W-2 employees or subcontractors, employee turnover rate, who supervises and how often they inspect, a written scope of work with task frequencies, and a 30-day out clause. Get three bids on the same written scope - otherwise you're comparing numbers that don't mean the same thing.
