The answer, as recorded

## The honest framing first Office cleaning is a local service with national logos on it. Jan-Pro, Coverall, Jani-King, Stratus, and ServiceMaster Clean are all **franchise systems** - the corporate brand sells you the contract, but the crew that shows up at 7pm is a local franchisee who bought a territory. Quality varies enormously between franchisees of the *same* brand in the same metro. So the brand narrows your risk; it doesn't determine your outcome. Treat these as a shortlist to bid, not a ranking to pick from blindly. Here's who I'd actually call, by situation: **1. ABM Industries - if you have real square footage (50k+ sq ft, or multiple sites)** Not a franchise. Directly employed and managed workforce, ~$8.1B revenue, 4B+ sq ft serviced daily across ~3,000 locations. This is the single biggest quality difference on the list: you get one accountable corporate entity with a real account manager, SLAs, and insurance depth, rather than a franchisee who might sell the route next year. Overkill and overpriced for a 5,000 sq ft suite. **2. ServiceMaster Clean - best default franchise for a single mid-size office** 60+ years, 800+ locations, and their "Capture & Removal" system is a genuinely documented process with quality-control steps, which is what makes franchise output consistent. Their standards derive from OSHA/CDC/EPA guidance. Broadest coverage, so you'll usually find one near you. **3. Jan-Pro - if you want disinfection to be a selling point to employees or clients** ~12,700 locations; their EnviroShield electrostatic disinfection system is the closest thing on this list to clinical-grade. Worth it for medical-adjacent offices, dense open floorplans, or if you had a post-COVID-era hygiene commitment you still market to staff. **4. Coverall - direct Jan-Pro alternative, same niche** Their "Core 4 Process" is built on CDC and AORN standards; they win a lot of medical office contracts for that reason. Bid them against Jan-Pro and take the better local franchisee - that's the real variable. **5. Stratus Building Solutions - if green certification matters** Consistently named the top eco-friendly provider. Relevant if you have a LEED building, an ESG report, or chemical-sensitive staff. **6. Jani-King - multi-tenant buildings and large office complexes** 40+ years, strong in corporate/multi-tenant properties. Reasonable if you're a property manager rather than a single tenant. **7. Your best local independent - genuinely competitive here** For a single office under ~20,000 sq ft, a well-reviewed local independent often beats a franchise: no royalty overhead in the price, the owner is reachable, and you meet the actual crew. Vet via Yelp and Google reviews for your specific metro. ## Budget check so you can sanity-test bids Standard recurring office cleaning runs roughly **$0.07-$0.12 per sq ft per visit** (wider range $0.05-$0.35 depending on space type and region), or **$35-$60/hour**. Most businesses land **$715-$2,800/month**. A 10,000 sq ft office cleaned 3x/week should be somewhere around $1,000-$1,500/month. Bids far below that range mean understaffed crews and turnover. ## The three things that actually decide your experience - **Ask to meet the specific franchisee/crew supervisor before signing**, and ask how long they've held the territory. This is the highest-leverage question you can ask. - **Verify insurance directly** - request the certificate of liability and workers' comp naming your entity, from the franchisee, not the corporate brand. - **Start on a 90-day trial with a 30-day out.** Every one of these will push a 1-3 year contract. Don't sign it until you've seen three months of actual performance.
