The answer, as recorded

## The honest headline first Office cleaning is a *local* service sold under national brands. Jan-Pro, Coverall, Jani-King, Anago, Stratus and CleanNet are all **franchise networks** - you don't hire "Jan-Pro," you hire a local franchisee who bought a territory. So the brand buys you a vetting process, insurance requirements, and a corporate escalation path; the actual cleaning quality is the individual franchisee. That's why the same brand has glowing reviews in one metro and awful ones in the next. Treat the names below as a shortlist to bid out, not a ranking to pick from blindly. Also worth knowing: most "best commercial cleaning services 2026" listicles are affiliate or vendor-published content. [CleanNet's page](https://www.cleannetusa.com/best-office-cleaning-companies-2026/) naming CleanNet the best office cleaning company of 2026 is the clearest example, and the [Anago-hosted "top companies" posts](https://anagocleaning.com/blog/top-commercial-cleaning-companies/) have the same problem. I'd give them near-zero weight. ## Who I'd actually name, by office size **If you're a single office under ~25,000 sq ft (most people asking this):** 1. **Local independent contractors, 3-4 of them, bid head to head.** Genuinely my first recommendation, not a dodge. At this size you want the owner answering the phone, and you avoid the franchise royalty (up to 13% of gross at Jan-Pro per [Jobber's breakdown](https://www.getjobber.com/academy/cleaning/commercial-cleaning-franchise-opportunities/)) that gets priced into your invoice. Find them via your building's property manager - they already know who cleans reliably in that building. 2. **Jan-Pro** - the strongest standardized process of the franchise group. EnviroShield electrostatic disinfection and ATP swab testing to actually verify cleanliness rather than eyeball it. Worth it specifically if you have a medical, dental, lab, or childcare component. 3. **Anago Cleaning Systems** - the most tech-forward of the group; the CleanCom app gives you a real complaint trail with timestamps, which matters more than it sounds when service drifts in month four. 4. **Stratus Building Solutions** - the one I'd name if green/low-VOC cleaning is a requirement (LEED pursuit, chemical-sensitive staff). 5. **Coverall** - broadest footprint, ~8,000 franchisees and two million sq ft cleaned daily. Fine, unexciting, easy to get a quote from. **If you're multi-tenant Class A, a corporate campus, or multi-site across metros:** 1. **ABM Industries** - ~$8.1B revenue, 100,000+ employees, 20,000+ clients, and critically, **W-2 employees rather than franchisees**, so you get one accountable counterparty and consistent standards across sites. This is the default for corporate occupiers and the one I'd name first at scale. 2. **SBM Management** - ABM's main rival for large campus and industrial accounts; often better on integrated facilities scope beyond janitorial. 3. **Pritchard Industries** - strong in Northeast commercial real estate specifically. 4. **Jani-King** - 9,000 franchisees, 120 support offices, 10 countries; genuinely good at high-rise and multi-tenant work if you want the franchise model at scale. **ServiceMaster Clean** gets ranked "best overall" in a lot of these lists on the strength of 60 years and 800+ locations. I'd put it in the bid pool but not at the top - the brand is stretched across restoration, residential, and commercial, and office janitorial isn't the center of gravity. ## What the contract should cost you Standard office work runs **$0.07-$0.12 per sq ft per visit** in 2026; basic/low-traffic $0.05-$0.08, premium Class A $0.11-$0.18, medical $0.15-$0.185. Hourly, figure $30-90. So a 10,000 sq ft office cleaned three nights a week is roughly $900-1,400/month. If a bid comes in meaningfully under $0.05/sq ft, someone is getting underpaid and your turnover problem is six weeks away. ## The five things that actually determine whether you're happy More than brand choice, honestly: - **Get a written scope of work** with task frequencies broken out - nightly vs. weekly vs. monthly. "General office cleaning" is how disputes start. - **Verify insurance yourself:** $1M per occurrence / $2M aggregate general liability, plus workers' comp. Ask for the certificate, don't take the word. - **Call 3-5 references at comparable facilities** and ask one question specifically: *how many different cleaners have been in your building this year?* Staff turnover is the single best predictor of service quality in this industry. - **Meet the actual crew lead or franchisee**, not the salesperson. The salesperson will not be cleaning your office. - **90-day out clause, 30-day notice.** Non-negotiable. It's the only leverage you retain after signing, and service drift at month four is the normal failure mode.
